The Kingdom of Hungary held a noble class of individuals, most of whom owned landed property, from the 11th century until the mid-20th century. Initially, a diverse body of people were described as noblemen, but from the late 12th century only high-ranking royal officials were regarded as noble. Most aristocrats claimed ancestry from chieftains of the period preceding the establishment of the kingdom around 1000; others were descended from western European knights who settled in Hungary. The lower-ranking castle warriors also held landed property and served in the royal army. From the 1170s, most privileged laymen called themselves royal servants to emphasize their direct connection to the monarchs. The Golden Bull of 1222 established their liberties, especially tax exemption and the limitation of military obligations. From the 1220s, royal servants were associated with the nobility and the highest-ranking officials were known as barons of the realm. Only those who owned allods – lands free of obligations – were regarded as true noblemen, but other privileged groups of landowners, known as conditional nobles, also existed.

In the 1280s, Simon of Kéza was the first to claim that noblemen held authority in the kingdom. The counties developed into institutions of noble autonomy, and the nobles' delegates attended the Diets (parliaments). The wealthiest barons built stone castles allowing them to control vast territories, but royal authority was restored in the early 14th century. In 1351, King Louis I introduced an entail system and enacted the principle of "one and the selfsame liberty" of all noblemen, but legal distinctions between true noblemen and conditional nobles prevailed. The most powerful nobles employed lesser noblemen as their familiares (retainers) but this private link did not sever the familiaris' direct subjection to the monarch. According to customary law, only males inherited noble estates, but under the Hungarian royal prerogative of prefection the kings could promote "a daughter to a son", allowing her to inherit her father's lands. Noblewomen who had married a commoner could also claim their inheritance – the daughters' quarter (that is one-quarter of their father's possessions) – in land.

Although the Tripartitum – a frequently cited compilation of customary law published in 1514 – reinforced the idea that all noblemen were equal, the monarchs granted hereditary titles to powerful aristocrats, and the poorest nobles lost their tax exemption from the mid-16th century. In the early modern period, because of the expansion of the Ottoman Empire, Hungary was divided into three parts: Royal Hungary, Transylvania and Ottoman Hungary. The princes of Transylvania supported the noblemen's fight against the Habsburg dynasty in Royal Hungary, but prevented the Transylvanian noblemen from challenging their own authority. Ennoblement of whole groups of people was not unusual in the 17th century. Examples include the 10,000 hajdú who received nobility as a group in 1605. After the Diet was divided into two chambers in Royal Hungary in 1608, noblemen with a hereditary title had a seat in the upper house, other nobles sent delegates to the lower house.

After the Ottomans' defeat in the Great Turkish War in the late 17th century, Transylvania and Ottoman Hungary were integrated into the Habsburg monarchy. The Habsburgs confirmed the nobles' privileges several times, but their attempts to strengthen royal authority regularly brought them into conflicts with the nobility, who represented nearly five percent of the population. Reformist noblemen demanded the abolition of noble privileges from the 1790s, but their program was enacted only during the Hungarian Revolution of 1848. Most noblemen lost their estates after the emancipation of their serfs, but the aristocrats preserved their distinguished social status. State administration employed thousands of impoverished noblemen in Austria-Hungary. Prominent (mainly Jewish) bankers and industrialists were awarded with nobility, but their social status remained inferior to traditional aristocrats. Noble titles were abolished only in 1947, months after Hungary was proclaimed a republic.

The Magyars (or Hungarians) lived in the Pontic steppes when they first appear in written sources from the mid-9th century. Muslim merchants described them as wealthy nomadic warriors, but they also noticed the Magyars had extensive arable lands. The Magyars crossed the Carpathian Mountains after the Pechenegs invaded their lands in 894 or 895. They settled in the lowlands along the Middle Danube, annihilated Moravia and defeated the Bavarians in the 900s. According to some scholarly theories, at least three Hungarian noble clans were descended from Moravian aristocrats who survived the Magyar conquest. Historians who are convinced that the Vlachs (or Romanians) were already present in the Carpathian Basin in the late 9th century propose that the Vlach knezes (or chieftains) also endured. Neither of these hypotheses are universally accepted.

Around 950, the Byzantine Emperor Constantine VII Porphyrogenitus (r. 913–959) wrote that the Hungarians were organized into "tribes", and each had its own "prince". The tribal leaders most probably bore the title úr (now "lord"), as it is suggested by Hungarian terms deriving from this word, such as ország (now "realm") and uralkodni ("to rule"). The Emperor noted the Magyars spoke both Hungarian and "the tongue of the Chazars" (a powerful steppe people), showing that at least their leaders were bilingual.

The Magyars lived a nomadic or semi-nomadic life but archaeological research shows that most settlements consisted of small pit-houses and log cabins in the 10th century. Tents in use are only mentioned in 12th-century literary sources. No archeological finds evidence fortresses in the Carpathian Basin in the 10th century, but fortresses were also rare in Western Europe during the same period. A larger log cabin – measuring five by five metres (16 ft × 16 ft) – which was built on a foundation of stones in Borsod was tentatively identified as the local leader's household.

More than a 1,000 graves yielding sabres, arrow-heads and bones of horses show that mounted warriors formed a significant group in the 10th century. The highest-ranking Hungarians were buried either in large cemeteries (where hundreds of their men were buried without weapons around their leader's burial place), or in small cemeteries with 25–30 graves. The wealthy warriors' burial sites yielded richly decorated horse harness, and sabretaches ornamented with precious metal plaques. Rich women's graves contained their braid ornaments and rings made of silver or gold and decorated with precious stones. The most widespread decorative motifs which can be regarded as tribal totems – the griffin, wolf and hind – were rarely applied in Hungarian heraldry in the following centuries. Defeats during the Hungarian invasions of Europe and clashes with the paramount rulers from the Árpád dynasty had decimated the leading families by the end of the 10th century. The Gesta Hungarorum, a chronicle written around 1200, claimed that dozens of noble kindred flourishing in the late 12th century had been descended from tribal leaders, but most modern scholars do not regard this list as a reliable source.

Stephen I (r. 997–1038), who was crowned the first king of Hungary in 1000 or 1001, defeated the last resisting tribal chieftains. Earthen forts were built throughout the kingdom and most of them developed into centers of royal administration. About 30 administrative units, known as counties, were established before 1040; more than 40 new counties were organized during the next centuries. Each county was headed by a royal official, the ispán. The royal court provided further career opportunities. As the historian Martyn Rady noted, the "royal household was the greatest provider of largesse in the kingdom" where the royal family owned more than two thirds of all lands. The palatine – the head of the royal household – was the highest-ranking royal official.

The kings from the Árpád dynasty appointed their officials from among the members of about 110 aristocratic clans. These aristocrats were descended either from native (that is, Magyar, Kabar, Pecheneg or Slavic) chiefs, or from foreign knights who had migrated to the country in the 11th and 12th centuries. The foreign knights had been trained in the Western European art of war, which contributed to the development of heavy cavalry in Hungary. Their descendants were labelled as newcomers for centuries, but intermarriage between natives and newcomers was not rare, which enabled their integration in two or three generations. The monarchs pursued an expansionist policy from the late 11th century. Ladislaus I (r. 1077–1095) seized Slavonia – the plains between the river Drava and the Dinaric Alps – in the 1090s. His successor, Coloman (r. 1095–1116), was crowned king of Croatia in 1102. Both realms retained their own customs, and Hungarians rarely received land grants in Croatia. According to customary law, Croatians could not be obliged to cross the river Drava to fight in the royal army at their own expense.

The earliest royal decrees authorized landowners to dispose freely of their private estates, but customary law prescribed that inherited lands could only be transferred with the consent of the owner's kinsmen who could potentially inherit them. From the early 12th century, only family lands traceable back to a grant made by Stephen I could be inherited by the deceased owner's distant relatives; other estates escheated to the Crown if their owner did not have offspring or brothers. Aristocratic families held their inherited domains in common for generations before the 13th century. Thereafter the division of inherited property became the standard practice. Even families descended from wealthy clans could become impoverished through the regular divisions of their estates.

Medieval documents mention the basic unit of estate organization as praedium or allodium. A praedium was a piece of land (either a whole village or part of it) with well-marked borders. Archaeologist Mária Wolf identifies the small motte forts, built on artificial mounds and protected by a ditch and a palisade that appeared in the 12th century, as the centers of private estates. Most wealthy landowners' domains consisted of scattered praedia, in several villages. Due to the scarcity of documentary evidence, the size of the private estates cannot be determined. The descendants of Otto Győr, the ispán of Somogy County remained wealthy landowners even after he donated 360 households to the newly established Zselicszentjakab Abbey in 1061. The establishment of monasteries by wealthy individuals was common. Such proprietary monasteries served as burial places for their founders and the founders' descendants, who were regarded as the co-owners, or from the 13th century, co-patrons, of the monastery. Serfs cultivated part of the praedium, but other plots were hired out in return for in-kind taxes.

The term "noble" was rarely used and poorly defined before the 13th century: it could refer to a courtier, a landowner with judicial powers, or even to a common warrior. The existence of a diverse group of warriors, who were subjected to the monarch, royal officials or prelates is well documented. The castle warriors, who were exempt from taxation, held hereditary landed property around the royal castles. Lightly armored horsemen, known as lövők (or archers), and armed castle folk, mentioned as őrök (or guards), defended the borderlands.

Official documents from the end of the 12th century only mentioned court dignitaries and ispáns as noblemen. This group had adopted most elements of chivalric culture. They regularly named their children after Paris of Troy, Hector, Tristan, Lancelot and other heroes of Western European chivalric romances. The first tournaments were held around the same time.

The regular alienation of royal estates is well-documented from the 1170s. The monarchs granted immunities, exempting the grantee's estates from the jurisdiction of the ispáns, or even renouncing royal revenues that had been collected there. Béla III (r. 1172–1196) was the first Hungarian monarch to give away a whole county to a nobleman: he granted Modrus in Croatia to Bartholomew of Krk in 1193, stipulating that the grantee was to equip warriors for the royal army. Béla's son, Andrew II (r. 1205–1235), decided to "alter the conditions" of his realm and "distribute castles, counties, lands and other revenues" to his officials, as he narrated in a document in 1217. Instead of granting the estates in fief, with an obligation to render future services, he gave them as allods, in reward for the grantee's previous acts. The great officers who were the principal beneficiaries of his grants were mentioned as barons of the realm from the late 1210s.

Donations of such a large scale accelerated the development of a wealthy group of landowners, most descending from a high-ranking kindred. Some wealthy landowners could afford to build stone castles. Closely related aristocrats were distinguished from other lineages through a reference to their (actual or presumed) common ancestor with the words de genere ("from the kindred"). Families descending from the same kindred adopted similar insignia. The author of the Gesta Hungarorum fabricated genealogies for them and emphasized that they could never be excluded from "the honor of the realm", that is from state administration.

The new owners of the transferred royal estates wanted to subjugate the freemen, castle warriors and other privileged groups of people living in or around their domains. The threatened groups wanted to achieve confirmation of their status as royal servants, emphasizing that they were only to serve the king. Béla III issued the first extant royal charter about the grant of this rank to a castle warrior. Andrew II's Golden Bull of 1222 enacted royal servants' privileges. They were exempt from taxation; they were to fight in the royal army without proper compensation only if enemy forces invaded the kingdom; only the monarch or the palatine could judge their cases. According to the Golden Bull, only royal servants who died without a son could freely will their estates, but even in this case, their daughters were entitled to the daughters' quarter. The final article of the Golden Bull authorized the bishops, barons and other nobles to resist the monarch if he ignored its provisions. Most provisions of the Golden Bull were first confirmed in 1231.

The clear definition of the royal servants' liberties distinguished them from all other privileged groups, whose military obligations remained theoretically unlimited. From the 1220s, the royal servants were regularly called noblemen and started to develop their own corporate institutions at the county level. In 1232, the royal servants of Zala County asked Andrew II to authorize them "to judge and do justice", stating that the county had slipped into anarchy. The king granted their request and Bartholomew, Bishop of Veszprém, sued one Ban Oguz for properties before their community.

The first Mongol invasion of Hungary in 1241 proved the importance of well-fortified locations and heavily armored cavalry. In the following decades, Béla IV of Hungary (r. 1235–1270) gave away large parcels of the royal demesne, expecting that the new owners would build stone castles there. Béla's burdensome castle-building program was unpopular, but achieved his aim: almost 70 castles were built or reconstructed during his reign. More than half of the new or reconstructed castles were in noblemen's domains. Most new castles were erected on rocky peaks, mainly along the western and northern borderlands. The spread of stone castles profoundly changed the structure of landholding, because castles could not be maintained without proper income. Lands and villages were legally attached to each castle, and castles were thereafter always transferred and inherited along with these "appurtenances".

The royal servants were legally identified as nobles in 1267. That year "the nobles of all Hungary, called royal servants" persuaded Béla IV and his son, Stephen V (r. 1270–1272), to hold an assembly and confirm their collective privileges. Other groups of land-holding warriors could also be called nobles, but they were always distinguished from the true noblemen. They held their estates conditionally, as they were required to provide well-defined services to another lord, hence their groups are now collectively known as conditional nobles. The noble Vlach knezes who had landed property in the Banate of Severin were obliged to fight in the army of the ban (or royal governor). Most warriors known as the "noble sons of servants" were descended from freemen or liberated serfs who received estates from Béla IV in Upper Hungary on the condition that they were to equip jointly a fixed number of knights. The nobles of the Church formed the armed retinue of the wealthiest prelates. The nobles of Turopolje in Slavonia were required to provide food and fodder to high-ranking royal officials. Two privileged groups, the Székelys and Saxons firmly protected their communal liberties, which prevented their leaders from exercising noble privileges in the Székely and Saxon territories in Transylvania. Székelys and Saxons could only enjoy the liberties of noblemen if they held estates outside the lands of the two privileged communities.

Most noble families failed to adopt a strategy to avoid the division of their inherited estates into dwarf-holdings through generations. Daughters could only demand the cash equivalent of the quarter of their father's estates, but younger sons rarely remained unmarried. Impoverished noblemen had little chance to receive land grants from the kings, because they were unable to participate in the monarchs' military campaigns, but commoners who bravely fought in the royal army were regularly ennobled.

The historian Erik Fügedi noted that "castle bred castle" in the second half of the 13th century: if a landowner erected a fortress, his neighbors would also build one to defend their own estates. Between 1271 and 1320, noblemen or prelates built at least 155 new fortresses. In comparison, only about a dozen castles were erected on the royal demesne. Most castles consisted of a tower, surrounded by a fortified courtyard, but the tower could also be built into the walls. Noblemen who could not erect fortresses were occasionally forced to abandon their inherited estates or seek the protection of more powerful lords, even through renouncing their liberties.

The lords of the castles had to hire a professional staff for the defence of the castle and the management of its appurtenances. They primarily employed nobles who held nearby estates, which gave rise to the development of a new institution, known as familiaritas. A familiaris was a nobleman who entered into the service of a wealthier landowner in exchange for a fixed salary or a portion of revenue, or rarely for the ownership or usufruct (right to enjoyment) of a piece of land. Unlike a conditional noble, a familiaris remained de jure an independent landholder, only subject to the monarch.

From the 1270s, the monarchs' coronation oath included a promise to respect the noblemen's liberties. The counties gradually transformed into an institution of the noblemen's local autonomy. Noblemen regularly discussed local matters at the counties' general assemblies. The sedria (the counties' law courts) became important elements in the administration of justice. They were headed by the ispáns or their deputies, but they consisted of four (in Slavonia and Transylvania, two) elected local noblemen, known as judges of the nobles.

Hungary fell into a state of anarchy because of the minority of Ladislaus IV (r. 1272–1290) in the early 1270s. To restore public order, the prelates convoked the barons and the delegates of the noblemen and the nomadic Cumans who had settled in Hungary to a general assembly near Pest in 1277. This first Diet (or parliament) declared the fifteen-year-old monarch to be of age in an attempt to put en end to the anarchy. In the early 1280s, Simon of Kéza associated the Hungarian nation with the nobility in his Deeds of the Hungarians, emphasizing that the community of noblemen held real authority.

The barons took advantage of the weakening of royal authority and seized large, contiguous territories. The monarchs could not appoint and dismiss their officials at will anymore. The most powerful barons – known as oligarchs in modern historiography – appropriated royal prerogatives, combining private lordship with their administrative powers. When Andrew III (r. 1290–1301), the last male member of the Árpád dynasty, died in 1301, about a dozen lords held sway over most parts of the kingdom.

Ladislaus IV's great-nephew, Charles I (r. 1301–1342), who was a scion of the Capetian House of Anjou, restored royal power in the 1310s and 1320s. He seized the oligarchs' castles mainly by force, which again secured the preponderance of the royal demesne. He refuted the Golden Bull in 1318 and claimed that noblemen had to fight in his army at their own expense. He ignored customary law and regularly "promoted a daughter to a son", granting her the right to inherit her father's estates. The King reorganized the royal household, appointing pages and knights to form his permanent retinue. He established the Order of Saint George, which was the first chivalric order in Europe. Charles I was the first Hungarian monarch to grant coats of arms (or rather crests) to his subjects. He based royal administration on honors (or office fiefs), distributing most counties and royal castles among his highest-ranking officials. These "baronies", as the historian Matteo Villani (d. 1363) recorded it in about 1350, were "neither hereditary nor lifelong", but Charles rarely dismissed his most trusted barons. Each baron was required to hold his own banderium (or armed retinue), distinguished by his own banner.

In 1351, Charles's son and successor, Louis I (r. 1342–1382) confirmed all provisions of the Golden Bull, save the one that authorized childless noblemen to freely will their estates. Instead, he introduced an entail system, prescribing that childless noblemen's landed property "should descend to their brothers, cousins and kinsmen". This new concept of aviticitas also protected the Crown's interests: only kin within the third degree could inherit a nobleman's property and noblemen who had only more distant relatives could not dispose of their property without the king's consent. Louis I emphasized all noblemen enjoyed "one and the selfsame liberty" in his realms and secured all privileges that nobles owned in Hungary proper to their Slavonian and Transylvanian peers. He rewarded dozens of Vlach knezes with true nobility for military merits. The vast majority of the Upper Hungarian "noble sons of servants" achieved the status of true noblemen without a formal royal act, because the memory of their conditional landholding fell into oblivion. Most of them preferred Slavic names even in the 14th century, showing that they spoke the local Slavic vernacular. Other groups of conditional nobles remained distinguished from true noblemen. They developed their own institutions of self-government, known as seats or districts. Louis decreed that only Catholic noblemen and knezes could hold landed property in the district of Karánsebes (now Caransebeș in Romania) in 1366, but Eastern Orthodox landowners were not forced to convert to Catholicism in other territories of the kingdom. Even the Catholic bishop of Várad (now Oradea in Romania) authorized his Vlach voivodes (leaders) to employ Orthodox priests. The king granted the Transylvanian district of Fogaras (around present-day Făgăraș in Romania) to Vladislav I of Wallachia (r. 1364–1377) in fief in 1366. In his new duchy, Vladislav donated estates to Wallachian boyars; their legal status was similar to the position of the knezes in other regions of Hungary.

Royal charters customarily identified noblemen and landowners from the second half of the 14th century. A man who lived in his own house on his own estates was described as living "in the way of nobles", in contrast with those who did not own landed property and lived "in the way of peasants". A verdict of 1346 declared that a noble woman who was given in marriage to a commoner should receive her inheritance "in the form of an estate in order to preserve the nobility of the descendants born of the ignoble marriage". According to the local customs of certain counties, her husband was also regarded as a nobleman – a noble by his wife.

The peasants' legal position had been standardized in almost the entire kingdom by the 1350s. The free peasant tenants were to pay seigneurial taxes, but were rarely obliged to provide labour service. In 1351, the king ordered that the ninth – a tax payable to the landowners – was to be collected from all tenants, thus preventing landowners from offering lower taxes to persuade tenants to move from other lords' lands to their estates. In 1328, all landowners were authorized to administer justice on their estates "in all cases except cases of theft, robbery, assault or arson" which remained under the jurisdiction of the sedria. The kings started to grant noblemen the right to execute or mutilate criminals who were captured in their estates. The most influential noblemen's estates were also exempted of the jurisdiction of the counties' law courts.

Royal power quickly declined after Louis I died in 1382. His son-in-law, Sigismund of Luxembourg (r. 1387–1437), entered into a formal league with the aristocrats who had elected him king in early 1387. Initially, when his position was weak, he gave away more than half of the 150 royal castles to his supporters, although this abated when he strengthened his authority in the early 15th century. His favorites were foreigners, but old Hungarian families also took advantage of his magnanimity. The wealthiest noblemen, known as magnates, built comfortable castles in the countryside which became important centers of social life. These fortified manor houses always contained a hall for representative purposes and a private chapel. Sigismund regularly invited the magnates to the royal council, even if they did not hold higher offices. He founded a new chivalric order, the Order of the Dragon, in 1408 to reward his most loyal supporters.

The expansion of the Ottoman Empire reached the southern frontiers in the 1390s. A large anti-Ottoman crusade ended with a catastrophic defeat near Nicopolis in 1396. Next year, Sigismund held a Diet in Temesvár (now Timișoara in Romania) to strengthen the defence system. He confirmed the Golden Bull, but without the two provisions that limited the noblemen's military obligations and established their right to resist the monarchs. The Diet obliged all landowners to equip one archer for every 20 peasant plots on their domains to serve in the royal army. Sigismund granted large estates in Hungary to neighboring Orthodox rulers to secure their alliance. They established Basilite monasteries on their estates.

Sigismund's son-in-law, Albert of Habsburg (r. 1438–1439), was elected king in early 1438, but only after he promised always to make important decisions with the consent of the royal council. After he died in 1439, a civil war broke out between the partisans of his son, Ladislaus the Posthumous (r. 1440–1457), and the supporters of the child king's rival, Vladislaus III of Poland (r. 1440–1444). Ladislaus the Posthumous was crowned without election with the Holy Crown of Hungary, but the Diet proclaimed the coronation invalid, stating that "the crowning of kings is always dependent on the will of the kingdom's inhabitants, in whose consent both the effectiveness and the force of the crown reside". Vladislaus died fighting the Ottomans during the Crusade of Varna in 1444 and the Diet elected seven captains in chief to administer the kingdom. The talented military commander, John Hunyadi (d. 1456), was elected the sole regent in 1446.

The Diet developed from a consultative body into an important institution of law making in the 1440s. The magnates were always invited to attend it in person. Lesser noblemen were also entitled to attend the Diet, but in most cases they were represented by delegates, who were almost always the magnates' familiares.

Hunyadi was the first noble to receive a hereditary title from a Hungarian king, when Ladislaus the Posthumous granted him the Saxon district of Bistritz (now Bistrița in Romania) with the title perpetual count in 1453. Hunyadi's son, Matthias Corvinus (r. 1458–1490), who was elected king in 1458, rewarded further noblemen with the same title. Fügedi states that 16 December 1487 was the "birthday of the estate of magnates in Hungary", because an armistice signed on this day listed 23 Hungarian "natural barons", contrasting them with the high officers of state, who were mentioned as "barons of office". Corvinus' successor, Vladislaus II (r. 1490–1516), and Vladislaus' son, Louis II (r. 1516–1526), formally began to reward important persons of their government with the hereditary title of baron.

Differences in the nobles' wealth increased in the second half of the 15th century. About 30 families owned more than a quarter of the territory of the kingdom when Corvinus died in 1490. A further tenth of all lands in the kingdom was in the possession of about 55 wealthy noble families. Other nobles held almost one third of the lands, but this group included 12–13,000 peasant-nobles who owned a single plot (or a part of it) and had no tenants. The Diets regularly compelled the peasant-nobles to pay tax on their plots. Average magnates held about 50 villages, but the regular division of inherited landed property could lead to the impoverishment of aristocratic families. Strategies applied to avoid this – family planning and celibacy – led to the extinction of most aristocratic families after a few generations.

The Diet ordered the compilation of customary law in 1498. The jurist István Werbőczy (d. 1541) completed the task, presenting a law-book at the Diet in 1514. His Tripartitum – The Customary Law of the Renowned Kingdom of Hungary in Three Parts – was never enacted, but it was consulted at the law courts for centuries. It summarized the noblemen's fundamental privileges in four points: noblemen were only subject to the monarch's authority and could only be arrested in a due legal process; furthermore, they were exempt from all taxes and were entitled to resist the king if he attempted to interfere with their privileges. Werbőczy also implied that Hungary was actually a republic of nobles headed by a monarch, stating that all noblemen "are members of the Holy Crown" of Hungary. Quite anachronistically, he emphasized the idea of all noblemen's legal equality, but he had to admit that the high officers of the realm, whom he mentioned as "true barons", were legally distinguished from other nobles. He also mentioned the existence of a distinct group, who were barons "in name only", but without specifying their peculiar status.

The Tripartitum regarded the kindred as the basic unit of nobility. A noble father exercised almost autocratic authority over his sons, because he could imprison them or offer them as a hostage for himself. His authority ended only if he divided his estates with his sons, but the division could rarely be enforced. The "betrayal of fraternal blood" (that is, a kinsman's "deceitful, sly, and fraudulent ... disinheritance") was a serious crime, which was punished by loss of honor and the confiscation of all property. Although the Tripartitum did not explicitly mention it, a nobleman's wife was also subject to his authority. She received her dower from her husband at the consummation of their marriage. If her husband died, she inherited his best coach-horses and clothes.

Demand for foodstuffs grew rapidly in Western Europe in the 1490s. The landowners wanted to take advantage of the growing prices. They demanded labour service from their peasant tenants and started to collect the seigneurial taxes in kind. The Diets passed decrees that restricted the peasants' right to free movement and increased their burdens. The peasants' grievances unexpectedly culminated in a rebellion in May 1514. The rebels captured manor houses and murdered dozens of noblemen, especially on the Great Hungarian Plain. The voivode of Transylvania, John Zápolya, annihilated their main army at Temesvár on 15 July. György Dózsa and other leaders of the peasant war were tortured and executed, but most rebels received a pardon. The Diet punished the peasantry as a group, condemning them to perpetual servitude and depriving them of the right of free movement. The Diet also enacted the serfs' obligation to provide one day's labour service for their lords each week.

The Ottomans annihilated the royal army at the Battle of Mohács. Louis II died fleeing from the battlefield and two claimants, John Zápolya (r. 1526–1540) and Ferdinand of Habsburg (r. 1526–1564), were elected kings. Ferdinand tried to reunite Hungary after Zápolya died in 1540, but the Ottoman Sultan, Suleiman the Magnificent (r. 1520–1566), intervened and captured Buda in 1541. The sultan allowed Zápolya's widow, Isabella Jagiellon (d. 1559), to rule the lands east of the river Tisza on behalf of her infant son, John Sigismund (r. 1540–1571), in return for a yearly tribute. His decision divided Hungary into three parts: the Ottomans occupied the central territories; John Sigismund's eastern Hungarian Kingdom developed into the autonomous Principality of Transylvania; and the Habsburg monarchs preserved the northern and western territories (or Royal Hungary).

Most noblemen fled from the central regions to the unoccupied territories. Peasants who lived along the borders paid taxes both to the Ottomans and their former lords. Commoners were regularly recruited to serve in the royal army or in the magnates' retinues to replace the noblemen who had perished during fights. The irregular hajdú foot-soldiers – mainly runaway serfs and dispossessed noblemen – became important elements of the defence forces. Stephen Bocskai, Prince of Transylvania (r. 1605–1606), settled 10,000 hajdús in seven villages and exempted them from taxation in 1605, which was the "largest collective ennoblement" in the history of Hungary.

In addition to the Székely and Saxon leaders, the noblemen formed one of the three nations (or Estates of the realm) in Transylvania, but they could rarely challenge the princes' authority. In Royal Hungary, the magnates successfully protected the noble privileges, because their vast domains were almost completely exempt from royal officials' authority. Their manors were fortified in the "Hungarian manner" (with walls made of earth and timber) in the 1540s. Noblemen in Royal Hungary could also count on the support of the Transylvanian princes against the Habsburg monarchs. Intermarriages among Austrian, Czech and Hungarian aristocrats gave rise to the development of a "supranational aristocracy" in the Habsburg monarchy. Foreign aristocrats regularly received Hungarian citizenship, and Hungarian noblemen were often naturalized in the Habsburgs' other realms. The Habsburg kings rewarded the most powerful magnates with hereditary titles such as baron from the 1530s.

The aristocrats supported the spread of the Reformation. Most noblemen adhered to Lutheranism in the western regions of Royal Hungary, but Calvinism was the dominant religion in Transylvania and other regions. John Sigismund promoted Unitarian views, but most Unitarian noblemen perished in battles in the early 1600s. The Habsburgs remained staunch supporters of the Catholic Counter-Reformation and the most prominent aristocratic families converted to Catholicism in Royal Hungary in the 1630s. The Calvinist princes of Transylvania supported their co-religionists. Gabriel Bethlen granted nobility to all Calvinist pastors.

The kings and the Transylvanian princes regularly ennobled commoners, but often without granting landed property to them. Jurisprudence maintained that only those who owned land cultivated by serfs could be regarded as fully fledged noblemen. Armalists – noblemen who held a charter of ennoblement, but not a single plot of land – and peasant-nobles continued to pay taxes, for which they were collectively known as taxed nobility. Nobility could be purchased from the kings who were often in need of funds. Landowners also benefitted from the ennoblement of their serfs, because they could demand a fee for their consent.

The Diet was officially divided into two chambers in Royal Hungary in 1608. All adult male members of the titled noble families had a seat in the Upper House. The lesser noblemen elected two or three delegates at the general assemblies of the counties to represent them in the Lower House. The Croatian and Slavonian magnates also had seats at the Upper House, and the sabor (or Diet) of Croatia and Slavonia sent delegates to the Lower House.

Forces from the Holy Roman Empire and the Polish–Lithuanian Commonwealth inflicted a crushing defeat on the Ottomans at Vienna in 1683. The Ottomans were expelled from Buda in 1686. Michael I Apafi, the prince of Transylvania (r. 1661–1690), acknowledged the suzerainty of Emperor Leopold I, who was also king of Hungary (r. 1657–1705), in 1687. Grateful for the liberation of Buda, the Diet abolished the noblemen's right to resist the monarch for the defense of their liberties. In 1688, the Diet authorized the aristocrats to establish a special trust, known as fideicommissum, with royal consent to prevent the distribution of their landed wealth among their descendants. In accordance with the traditional concept of aviticitas, inherited estates could not be subject to the trust. Estates in fideicommissum were always held by one person, but he was responsible for the proper boarding of his relatives.

The liberation of central Hungary continued, and the Ottomans were forced to acknowledge the loss of the territory in 1699. Leopold set up a special committee to distribute the lands in the reconquered territories. The descendants of the noblemen who had held estates there before the Ottoman conquest were required to provide documentary evidence to substantiate their claims to the ancestral lands. Even if they could present documents, they were to pay a fee – a tenth of the value of the claimed property – as compensation for the costs of the liberation war. Few noblemen could meet the criteria and more than half of the recovered lands were distributed among foreigners. They were naturalized, but most of them never visited Hungary.

The Habsburg administration doubled the amount of the taxes to be collected in Hungary and demanded almost one third of the taxes (1.25 million florins) from the clergy and the nobility. The palatine, Prince Paul Esterházy (d. 1713), convinced the monarch to reduce the noblemen's tax burden to 0.25 million florins, but the difference was to be paid by the peasantry. Leopold did not trust the Hungarians, because a group of magnates had conspired against him in the 1670s. Mercenaries replaced the Hungarian garrisons, and they frequently plundered the countryside. The monarch also supported Cardinal Leopold Karl von Kollonitsch's attempts to restrict the Protestants' rights. Tens of thousands of Catholic Germans and Orthodox Serbs were settled in the reconquered territories.

The outbreak of the War of the Spanish Succession (1701–1715) provided an opportunity for the discontented Hungarians to rise against Leopold. They regarded one of the wealthiest aristocrats, Prince Francis II Rákóczi (d. 1735), as their leader. Rákóczi's War of Independence lasted from 1703 to 1711. Although the rebels were forced to yield, the Treaty of Szatmár granted a general amnesty for them and the new Habsburg monarch, Charles III (r. 1711–1740), promised to respect the privileges of the Estates of the realm.

Charles III again confirmed the privileges of the Estates of the "Kingdom of Hungary, and the Parts, Kingdoms and Provinces thereto annexed" in 1723 in return for the enactment of the Pragmatic Sanction which established his daughters' right to succeed him. Montesquieu, who visited Hungary in 1728, regarded the relationship between the king and the Diet as a good example of the separation of powers. The magnates almost monopolized the highest offices, but both the Hungarian Court Chancellery – the supreme body of royal administration – and the Lieutenancy Council – the most important administrative office – also employed lesser noblemen. In practice, Protestants were excluded from public offices after a royal decree, the Carolina Resolutio, obliged all candidates to take an oath on the Virgin Mary.

The Peace of Szatmár and the Pragmatic Sanction maintained that the Hungarian nation consisted of the privileged groups, independent of their ethnicity, but the first debates along ethnic lines occurred in the early 18th century. The jurist Mihály Bencsik claimed that the burghers of Trencsén (now Trenčín in Slovakia) should not send delegates to the Diet because their ancestors had been forced to yield to the conquering Magyars in the 890s. A priest, Ján B. Magin, wrote a response, arguing that ethnic Slovaks and Hungarians enjoyed the same rights. In Transylvania, a bishop of the Romanian Greek Catholic Church, Baron Inocențiu Micu-Klein (d. 1768), tried to speak "on behalf of the whole Romanian nation in Transylvania" at the Diet in 1737 but he could not finish the speech because other delegates stated that he could refer only to the Romanians or to the Romanian people for the Romanian Nation did not exist. Five years later, he unsuccessfully demanded the recognition of the Romanians as the fourth Nation on ethnic grounds.

Maria Theresa (r. 1740–1780) succeeded Charles III in 1740, which gave rise to the War of the Austrian Succession. The noble delegates offered their "lives and blood" for their new "king" and the declaration of the general levy of the nobility was crucial at the beginning of the war. Grateful for their support, Maria Theresa strengthened the links between the Hungarian nobility and the monarch. She established the Theresian Academy and the Royal Hungarian Bodyguard for young Hungarian noblemen. Both institutions enabled the spread of the ideas of the Age of Enlightenment. Freemasonry became popular, especially among the magnates, but masonic lodges were also open to untitled noblemen and professionals.

Cultural differences between the magnates and lesser noblemen grew. The magnates adopted the lifestyle of the imperial aristocracy, moving between their summer palaces in Vienna and their newly built splendid residences in Hungary. Prince Miklós Esterházy (d. 1790) employed the celebrated composer Joseph Haydn. Count János Fekete (d. 1803), a fierce protector of noble privileges, bombarded the French philosopher Voltaire with letters and dilettante poems. Count Miklós Pálffy (d. 1773) proposed to tax the nobles to finance a standing army. Most noblemen were unwilling to renounce their privileges. Lesser noblemen also insisted on their traditional way of life and lived in simple houses, made of timber or packed clay.

Maria Theresa did not hold Diets after 1764. She regulated the relationship of landowners and their serfs in a royal decree in 1767. Her son and successor, Joseph II (r. 1780–1790), mocked as the "king in hat", was never crowned, because he wanted to avoid the coronation oath. He introduced reforms which clearly contradicted local customs. He replaced the counties with districts and appointed royal officials to administer them. He also abolished serfdom, securing all peasants the right to free movement after the revolt of Romanian serfs in Transylvania. He ordered the first census in Hungary in 1784. According to its records, the nobility made up about 4.5 percent of the male population in the Lands of the Hungarian Crown (with 155,519 noblemen in Hungary proper, and 42,098 noblemen in Transylvania, Croatia and Slavonia). The nobles' proportion was significantly higher (six–sixteen percent) in the northeastern and eastern counties, and less (three percent) in Croatia and Slavonia. Poor noblemen, who were mocked as "nobles of the seven plum trees" or "sandal-wearing nobles", made up almost 90 percent of the nobility. Previous investigations of nobility show that more than half of the noble families received their rank after 1550.

The few reformist noblemen greeted the news of the French Revolution with enthusiasm. József Hajnóczy [eo] (d. 1795) translated the Declaration of the Rights of Man and of the Citizen into Latin, and János Laczkovics [hu] (d. 1795) published its Hungarian translation. To appease the Hungarian nobility, Joseph II revoked almost all his reforms on his deathbed in 1790. His successor, Leopold II (r. 1790–1792), convoked the Diet and confirmed the liberties of the Estates of the realm, emphasizing Hungary was a "free and independent" realm, governed by its own laws. News about the Jacobin terror in France strengthened royal power. Hajnóczy and other radical (or "Jacobin") noblemen, who had discussed the possibility of the abolition of all privileges in secret societies, were captured and executed or imprisoned in 1795. The Diets voted in favor of the taxes and the recruits that Leopold's successor, Francis (r. 1792–1835), demanded between 1792 and 1811.

The last general levy of the nobility was declared in 1809, but Napoleon easily defeated the noble troops near Győr. Agricultural bloom encouraged the landowners to borrow money and to buy new estates or to establish mills during the war, but most of them went bankrupt after peace was restored in 1814. The concept of aviticitas prevented both the creditors from collecting their money and the debtors from selling their estates. Radical nobles played a crucial role in the reform movements of the early 19th century. Gergely Berzeviczy (d. 1822) attributed the backwardness of the local economy to the peasants' serfdom already around 1800. Ferenc Kazinczy (d. 1831) and János Batsányi (d. 1845) initiated language reform, fearing the disappearance of the Hungarian language. The poet Sándor Petőfi (d. 1849), who was a commoner, ridiculed the conservative noblemen in his poem The Magyar Noble, contrasting their anachronistic pride and their idle way of life.

From the 1820s, a new generation of reformist noblemen dominated political life. Count István Széchenyi (d. 1860) demanded the abolition of the serfs' labour service and the entail system, stating that, "We, well-to-do landowners are the main obstacles to the progress and greater development of our fatherland". He established clubs in Pressburg and Pest and promoted horse racing, because he wanted to encourage the regular meetings of magnates, lesser noblemen and burghers. Széchenyi's friend, Baron Miklós Wesselényi (d. 1850), demanded the creation of a constitutional monarchy and the protection of civil rights. A lesser nobleman, Lajos Kossuth (d. 1894), became the leader of the most radical politicians in the 1840s. He declared that the Diets and the counties were the privileged groups' institutions, and that only a wider social movement could secure the development of Hungary.

Since the end of the Age of Enlightenment, nationality was more and more associated with the vernacular. Predictions by the German Romantic philosopher Johann Gottfried Herder (d. 1803) about the inevitable assimilation of small peoples to a large linguistic group fanned the flames of linguistic nationalism. Although ethnic Hungarians made up only about 38 percent of the population, the official use of the Hungarian language spread from the late 18th century. Kossuth declared that all who wanted to enjoy the liberties of the nation should learn Hungarian. In contrast, the Slovak Ľudovít Štúr (d. 1856) stated that the Hungarian nation consisted of many nationalities and their loyalty could be strengthened by the official use of their languages. Count Janko Drašković (d. 1856) recommended that Croatian should replace Latin as the official language in Croatia and Slavonia.

News of the Revolutions of 1848 reached Pest on 15 March 1848. Young intellectuals proclaimed a radical program, known as the Twelve Points, demanding equal civil rights to all citizens. Count Lajos Batthyány (d. 1849) was appointed the first prime minister of Hungary. The Diet quickly enacted the majority of the Twelve Points, and Ferdinand V (r. 1835–1848) sanctioned them in April.

The April Laws abolished the nobles' tax-exemption and the aviticitas, but the magnates' 31 fideicommissa remained intact. Although the peasant tenants received the ownership of their plots, a compensation was promised to the landowners. Adult men who owned more than 0.032 km (7.9 acres) of arable lands or urban estates with a value of at least 300 florins – about one quarter of the adult male population – were granted the right to vote in the parliamentary elections. The noblemen's exclusive franchise in county elections was confirmed, otherwise ethnic minorities could have easily dominated the general assemblies in many counties. Noblemen made up about one quarter of the members of the new parliament, which assembled after the general elections on 5 July.

The Slovak delegates demanded autonomy for all ethnic minorities at their assembly in May. Similar demands were adopted at the Romanian delegates' meeting. Ferdinand V's advisors persuaded the ban (or governor) of Croatia, Baron Josip Jelačić (d. 1859), to invade Hungary proper in September. A new war of independence broke out and the Hungarian parliament dethroned the Habsburg dynasty on 14 April 1849. Nicholas I of Russia (r. 1825–1855) intervened on the legitimist side and Russian troops overpowered the Hungarian army, forcing it to surrender on 13 August.

Hungary, Croatia (and Slavonia) and Transylvania were incorporated as separate realms in the Austrian Empire. The advisors of the young emperor, Franz Joseph (r. 1848–1916), declared that Hungary had lost its historic rights and the conservative Hungarian aristocrats could not persuade him to restore the old constitution. Noblemen who had remained loyal to the Habsburgs were appointed to high offices, but most new officials came from other provinces of the empire. The vast majority of noblemen opted for a passive resistance: they did not hold offices in state administration and tacitly obstructed the implementation of imperial decrees. An untitled nobleman from Zala County, Ferenc Deák (d. 1876), became their leader around 1854. They tried to preserve an air of superiority, but their vast majority was assimilated to the local peasantry or petty bourgeoisie during the following decades. In contrast to them, the magnates, who retained about one quarter of all lands, could easily raise funds from the developing banking sector to modernize their estates.

Deák and his followers knew the great powers did not support the disintegration of the Austrian Empire. Austria's defeat in the Austro-Prussian War of 1866 accelerated the rapprochement between the king and the Deák Party, which led to the Austro-Hungarian Compromise of 1867. Hungary proper and Transylvania were united and the autonomy of Hungary was restored within the Dual Monarchy of Austria-Hungary. Next year, the Croatian–Hungarian Settlement restored the union of Hungary proper and Croatia, but secured the competence of the Croatian sabor in internal affairs, education and justice.

The Compromise strengthened the position of the traditional political elite. Only about six percent of the population could vote in the general elections. More than half of the prime ministers and one third of the ministers were appointed from among the magnates from 1867 to 1918. Landowners made up the majority of the members of parliament. Half of the seats in municipal assemblies were preserved for the greatest taxpayers. Noblemen also dominated the state administration, because tens of thousands of impoverished nobles took jobs at the ministries, or at the state-owned railways and post offices. They were ardent supporters of Magyarization, denying the use of minority languages. An emigrant aristocrat Baroness Emma Orczy (d. 1947) wrote her novels in English in the United Kingdom. She had left Hungary with her parents when farm workers fearing of losing their job set the Orczy manor on fire at Abádszalók in 1868. Her first novel featuring the Scarlet Pimpernel – "the first character who could be called a superhero" (Stan Lee) – was published in 1905.

Only nobleman who owned an estate of at least 1.15 km (280 acres) were regarded as prosperous, but the number of estates of that size quickly decreased. The magnates took advantage of lesser noblemen's bankruptcies and bought new estates during the same period. New fideicommissa were created which enabled the magnates to preserve the entailment of their landed wealth. Aristocrats were regularly appointed to the boards of directors of banks and companies.

Jews were the prime movers of the development of the financial and industrial sectors. Jewish businessmen owned more than half of the companies and more than four-fifths of the banks in 1910. They also bought landed property and had acquired almost one-fifth of the estates of between 1.15–5.75 km (280–1,420 acres) by 1913. The most prominent Jewish burghers were awarded with nobility and there were 26 aristocratic families and 320 noble families of Jewish origin in 1918. Many of them converted to Christianity, but other nobles did not regard them as their peers.

The First World War brought about the dissolution of Austria-Hungary in 1918. The Aster Revolution – a movement of the left-liberal Party of Independence, the Social Democratic Party and the Radical Citizens' Party – persuaded Charles IV (r. 1916–1918), to appoint the radical Count Mihály Károlyi (d. 1955), prime minister on 31 October. After the Lower House dissolved itself, Hungary was proclaimed a republic on 16 November. The Hungarian National Council adopted a land reform setting the maximum size of the estates at 1.15 square kilometres (280 acres) and ordering the distribution of any excess among the local peasantry. Károlyi, whose inherited domains had been mortgaged to banks, was the first to implement the reform.

The Allied Powers authorized Romania to occupy new territories and ordered the withdrawal of the Royal Hungarian Army almost as far as the Tisza on 26 February 1919. Károlyi resigned and the Hungarian Communist Party leader Béla Kun (d. 1938) announced the establishment of the Hungarian Soviet Republic on 21 March. All estates of over 0.43 km (110 acres) and all private companies employing more than 20 workers were nationalized. The Bolsheviks could not stop the Romanian invasion and their leaders fled from Hungary on 1 August. After a short-lived temporary government, the industrialist István Friedrich (d. 1951) formed a coalition government with the support of the Allied Powers on 6 August. The Bolsheviks' nationalization program was abolished. The Hungarian Social Democratic Party boycotted the general elections in early 1920. The new one-chamber Diet of Hungary restored the Hungarian monarchy, but without restoring the Habsburgs. Instead, a Calvinist nobleman, Miklós Horthy (d. 1957), was elected regent on 1 March 1920. Hungary had to acknowledge the loss of more than two thirds of its territory and more than 60 percent of its population (including one third of the ethnic Hungarians) in the Treaty of Trianon on 4 June.

Horthy was never crowned king, and therefore could not grant nobility, but he established a new order of merit, the Order of Gallantry. Its members received the hereditary title of vitéz ("brave"). They were also granted parcels of land, which renewed the "medieval link between land tenure and service to the crown" (Bryan Cartledge). Two Transylvanian aristocrats, Counts Pál Teleki (d. 1941) and István Bethlen (d. 1946), were the most influential politicians in the interwar period. The events of 1918–19 convinced them that only a "conservative democracy", dominated by the landed nobility, could secure stability. Most ministers and the majority of the members of the parliament were nobles. A conservative agrarian reform – limited to 8.5 percent of all arable lands – was introduced, but almost one third of the lands remained in the possession of about 400 magnate families. The two-chamber parliament was restored in 1926, with an Upper House dominated by the aristocrats, prelates and high-ranking officials.

Antisemitism was a leading ideology in the 1920s and 1930s. A numerus clausus law limited the admission of Jewish students in the universities. Count Fidél Pálffy (d. 1946) was one of the leading figures of the national socialist movements, but most aristocrats disdained the radicalism of "petty officers and housekeepers". Hungary participated in the Axis invasion of Yugoslavia in April 1941 and joined the war against the Soviet Union after the bombing of Kassa in late June. Fearing the defection of Hungary from the war, Nazi Germany occupied the country in Operation Margarethe on 19 March 1944. Hundreds of thousands of Jews and tens of thousands of Romani were transferred to Nazi concentration camps with the local authorities' assistance. The wealthiest business magnates of Jewish origin were forced to renounce their companies and banks to redeem their own and their relatives' lives.

The Soviet Red Army reached the Hungarian borders and took possession of the Great Hungarian Plain by 6 December 1944. Delegates from the region's towns and villages established the Provisional National Assembly in Debrecen, which elected a new government on 22 December. Three prominent Anti-Nazi aristocrats had a seat in the assembly. The Provisional National Government soon promised land reform, along with the abolishment of all "anti-democratic" laws. The last German Wehrmacht troops left Hungary on 4 April 1945.

Imre Nagy (d. 1958), the Communist Minister of Agriculture, announced land reform on 17 March 1945. All domains of more than 5.75 km (1,420 acres) were confiscated and the owners of smaller estates could retain a maximum 0.58–1.73 km (140–430 acres) of land. The land reform, as Cartledge noted, destroyed the nobility and eliminated the "elements of feudalism, which had persisted for longer in Hungary than anywhere else in Europe". Similar land reforms were introduced in Romania and Czechoslovakia. In both countries, ethnic Hungarian aristocrats were sentenced to death or prison as alleged war criminals. Hungarian aristocrats could retain their estates only in Burgenland (in Austria) after 1945.

Soviet military authorities controlled the general elections and the formation of a coalition government in late 1945. The new parliament declared the Second Hungarian Republic on 1 February 1946. An opinion poll showed that more than 75 percent of men and 66 percent of women were opposed to the use of noble titles in 1946. The parliament adopted an act that abolished all noble ranks and related styles, also banning their use. The new act came into force on 14 February 1947.

The Communists took full control of the government between 1947 and 1949, and Hungary was proclaimed a "people's republic" on 20 August 1949. The aristocrats were declared as "class enemies", and most of them interned to "social camps" – actually, forced labour camps – to work in the fields in the Great Hungarian Plain. Mass internal deportations occurred in 1950 and 1951. Almost all aristocrats were interned from Budapest to under-populated villages in eastern Hungary, primarily in Hortobágy region within two months in May–July 1951. Figures of a final report shows that 9 dukes, 163 counts, 121 barons and 8 knighted noblemen – altogether 301 aristocrats – and their families were deported from the capital during this period. The deportees were prohibited to leave the boundary of their assigned village and were under constant police surveillance. They were deprived of their belongings, properties and civil rights – they were prohibited to take part in elections. Most of them could work as manual workers in agriculture at state farms on a limited basis, but their deprivation was constant.

Some leftist aristocrats tried to cooperate with the new regime but the Communist leaders did not trust them. As a consequence of the Khrushchev Thaw, those who had been interned were allowed to leave the labour camps, but their former homes were not restored to them. Although Communist historians did their utmost to prove the aristocrats' preeminent role during the failed anti-Communist Hungarian revolution of 1956, few aristocrats took an active part. Many aristocrats left the country following the suppression of the 1956 revolt. During the 1960s and 1970s, people of aristocratic descent were mainly employed as blue-collar workers, and their children needed a special permit for studying at universities until 1962. Although official discrimination was abolished, former aristocrats were rarely appointed to higher positions. Péter Esterházy (d. 2016) became a celebrated writer during the last decades of the Communist regime.

The Communist one-party system collapsed in the late 1980s, and Hungary was proclaimed a republic in 1989. The first prime minister of the democratic era, József Antall (d. 1993) offered positions in state administration to aristocrats who returned to Hungary, but the aristocracy did not regain its former position. The restitution of former property was an important political issue in most new democracies in the early 1990s. In Hungary, in kind restitution was excluded because many pieces of formerly confiscated property had already been privatized during the last years of the Communist regime. Instead, monetary compensation was made available to the original owners and their descendants but its amount was limited to about US$70,000. In contrast, in kind restitution was the preferred method of restitution in Czechoslovakia, and the original owners could also claim in kind restitution in Romania and Poland. Hungarian aristocrats regained part of their former properties in Romania, and at least one Hungarian noble family also seized property in the Czech Republic, Poland and Slovakia during the restitution process.

The Hungarian act banning the use of noble ranks and styles has not been abolished, and the Constitutional Court of Hungary declared, in 2009 and 2010, that the ban was fully in line with the revised Hungarian Constitution of 1949. In December 2010, two members of the rightist Jobbik Group submitted a draft for the abolition of the ban but they withdrew it in two weeks. On the initiative of the former aristocrat János Nyáry, a private club, the Association of Hungarian Noble Families, was established for people of noble descent in Budapest in 1994. The association became a member of the European Commission of the Nobility in 2007.
