The French Foreign Legion (French: Légion étrangère, also known simply as la Légion, "the Legion") is an elite corps of the French Army created to allow foreign nationals into French service. The Legion was founded in 1831 and today consists of several specialties, namely infantry, cavalry, engineers, and airborne troops. It formed part of the Armée d’Afrique, French Army units associated with France's colonial project in North Africa, until the end of the Algerian War in 1962.

Legionnaires are today renowned as highly trained soldiers whose training focuses on traditional military skills and on the Legion's strong esprit de corps, as its men come from different countries with different cultures. Consequently, training is often described as not only physically challenging, but also very stressful psychologically. Legionnaires may apply for French citizenship after three years' service, or immediately after being wounded in the line of duty: This latter provision is known as "Français par le sang versé" ("French by spilled blood").

The Foreign Legion was created by Louis Philippe, the King of the French, on 10 March 1831 to allow the incorporation of foreign nationals into the French Army from the foreign regiments of the Kingdom of France. Recruits included soldiers from the recently disbanded Swiss and German foreign regiments of the Bourbon monarchy. The Royal Ordinance for the establishment of the new regiment specified that the foreigners recruited could only serve outside France. The French expeditionary force that had occupied Algiers in 1830 was in need of reinforcements, and the Legion was accordingly transferred by sea in detachments from Toulon to Algeria. Since its establishment in 1831, the Legion has consisted of hundreds of thousands in active service at its peak, and suffered the aggregated loss of nearly 40,000 men in France, Algeria, Morocco, Tunisia, Madagascar, West Africa, Mexico, Italy, Crimea, Spain, Indo-China, Norway, Syria, Chad, Zaïre, Lebanon, Central Africa, Gabon, Kuwait, Rwanda, Djibouti, former Yugoslavia, Somalia, the Republic of Congo, Ivory Coast, Afghanistan, Mali, as well as others. The Legion was primarily used to help protect and expand the French colonial empire during the 19th century. The Foreign Legion was initially stationed only in Algeria, where it took part in the Algerian genocide and destruction of the natural habitat of the colony. Subsequently, the Foreign Legion was deployed in a number of conflicts, including the First Carlist War in 1835, the Crimean War in 1854, the Second Italian War of Independence in 1859, the French intervention in Mexico in 1863, the Franco-Prussian War in 1870, the Tonkin Campaign and Sino-French War in 1883, supporting growth of the French colonial empire in Sub-Saharan Africa, the Second Franco-Dahomean War in 1892, the Second Madagascar expedition in 1895 and the Mandingo Wars in 1894. In World War I, the Foreign Legion fought in many critical battles on the Western Front. It played a smaller role in World War II than in World War I, however, participated in the Norwegian, Syrian and North African campaigns. During the First Indochina War (1946–1954), the Foreign Legion saw its numbers swell. In Vietnam, the Legion lost a large number of men in the catastrophic Battle of Dien Bien Phu against forces of the Viet Minh.

Subsequent military campaigns included those during the Suez Crisis, the Battle of Algiers and various offensives in Algeria launched by General Maurice Challe including Operation Oranie and Operation Jumelles. During the Algerian War of Independence (1954–1962), the Foreign Legion came close to being disbanded after some officers, men, and the highly decorated 1st Foreign Parachute Regiment (1 REP) took part in the Generals' putsch. In the 1960s and 1970s, Legion regiments had additional roles in sending units as a rapid deployment force to preserve French interests – in its former African colonies and in other nations as well; it also returned to its roots of being a unit always ready to be sent to conflict zones around the world.

Some notable operations include the Chadian–Libyan conflict in 1969–1972 (the first time that the Legion was sent in operations after the Algerian War), 1978–1979, and 1983–1987; Kolwezi in what is now the Democratic Republic of the Congo in May 1978. In 1981, the 1st Foreign Regiment and Foreign Legion regiments took part in the Multinational Force in Lebanon. In 1990, Foreign Legion regiments were sent to the Persian Gulf and participated in Opération Daguet, part of Division Daguet. Following the Gulf War in the 1990s, the Foreign Legion helped with the evacuation of French citizens and foreigners in Rwanda, Gabon and Zaire. The Foreign Legion was also deployed to Cambodia, Somalia, Sarajevo, Bosnia and Herzegovina. In the mid-to late 1990s, the Foreign Legion was deployed to the Central African Republic, Congo-Brazzaville and in Kosovo. The French Foreign Legion also took part in operations in Rwanda in 1990–1994; and the Ivory Coast from 2002 to the present. In the 2000s, the Foreign Legion was deployed to Operation Enduring Freedom in Afghanistan, Opération Licorne in Ivory Coast, the EUFOR Tchad/RCA in Chad, and Operation Serval in the Northern Mali conflict.

As discussed below, other countries have attempted to emulate the French Foreign Legion model. The Foreign Legion was primarily used, as part of the Armée d'Afrique, to protect and expand the French colonial empire during the 19th century, but it also fought in almost all French wars including the Franco-Prussian War, World War I and World War II. The Foreign Legion has remained an important part of the French Army, and sea transport protected by the French Navy survived three Republics, the Second French Empire, two World Wars, the rise and fall of mass conscript armies, the dismantling of the French colonial empire, and the loss of the Foreign Legion's base, Algeria.

Created to fight "outside mainland France", the Foreign Legion was stationed in Algeria, where it took part in the Algerian genocide and destruction of the natural habitat of the colony, notably by drying the marshes in the region of Algiers. The Foreign Legion was initially divided into six "national battalions" (Swiss, Poles, Germans, Italians, Spanish, and Dutch-Belgian). Smaller national groups, such as ten Englishmen recorded in December 1832, appear to have been placed randomly.

In late 1831, the first legionnaires landed in Algeria, the country that shaped its character and became the Foreign Legion's homeland for 130 years. The early years in Algeria were hard on the legion because it was often sent to the worst postings and received the worst assignments, and its members were generally uninterested in the new colony of the French. The Legion served alongside the Battalions of Light Infantry of Africa, formed in 1832, which was a penal military unit made up of men with prison records who still had to do their military service or soldiers with serious disciplinary problems.

The Foreign Legion's first service in Algeria came to an end after only four years, as it was needed elsewhere.

The French government sent the Foreign Legion to Spain to support Isabella II’s claim to the Spanish throne against her uncle. On 28 June 1835, the unit was handed over to the Spanish government. The Foreign Legion landed via sea at Tarragona on 17 August with around 1,400 who were quickly dubbed Los Argelinos (the Algerians) by locals because of their previous posting.

The Foreign Legion's commander immediately dissolved the national battalions to improve the esprit de corps. Later, he also created three squadrons of lancers and an artillery battery from the existing force to increase independence and flexibility. The Foreign Legion was dissolved on 8 December 1838, when it had dropped to only 500 men. The survivors returned to France, many reenlisting in the new Foreign Legion along with many of their former Carlist enemies.

On 9 June 1854, the French ship Jean Bart embarked four battalions of the Foreign Legion for the Crimean Peninsula. A further battalion was stationed at Gallipoli as brigade depot. Eight companies drawn from both regiments of the Foreign Legion took part in the Battle of Alma (20 September 1854). Reinforcements by sea brought the Legion contingent up to brigade strength. As the "Foreign Brigade", it served in the Siege of Sevastopol, during the winter of 1854–1855.

The lack of equipment was particularly challenging and cholera hit the Allied expeditionary force. Nevertheless, the "leather bellies" (the nickname given to the legionnaires by the Russians because of the large cartridge pouches that they wore attached to their waist-belts), performed well. On 21 June 1855, the Third Battalion, left Corsica for Crimea.

On 8 September the final assault was launched on Sevastopol. Two days later, the Second Foreign Regiment with flags and band playing ahead, marched through the streets of Sevastopol. Although initial reservations had been expressed about whether the Legion should be used outside Africa, the Crimean experience established its suitability for service in European warfare, as well as making a cohesive single entity of what had previously been two separate foreign regiments. Legion casualties in the Crimea were 1,703 killed and wounded out of total French losses by battle and disease of 95,615.

Like the rest of the "Army of Africa", the Foreign Legion provided detachments in the campaign of Italy. Two foreign regiments, grouped with the 2nd Regiment of Zouaves, were part of the Second Brigade of the Second Division of Mac Mahon's Corps. The Foreign Legion acquitted itself particularly well against the Austrians at the battle of Magenta (4 June 1859) and at the Battle of Solferino (24 June). Legion losses were significant and the 2nd Foreign Regiment lost Colonel Chabrière, its commanding officer. In gratitude, the city of Milan awarded, in 1909, the "commemorative medal of deliverance", which still adorns the regimental flags of the Second Regiment.

The 38,000 strong French expeditionary force dispatched to Mexico via sea between 1862 and 1863 included two battalions of the Foreign Legion, increased to six battalions by 1866. Small cavalry and artillery units were raised from legionnaires serving in Mexico. The original intention was that Foreign Legion units should remain in Mexico for up to six years to provide a core for the Imperial Mexican Army. However the Legion was withdrawn with the other French forces during February–March 1867.

It was in Mexico on 30 April 1863 that the Legion earned its legendary status. A company led by Captain Jean Danjou, numbering 62 Legionnaires and 3 Legion officers, was escorting a convoy to the besieged city of Puebla when it was attacked and besieged by three thousand Mexican loyalists, organised in two battalions of infantry and cavalry, numbering 2,200 and 800 respectively. The Legion detachment under Danjou, Sous-Lieutenant Jean Vilain, and Sous-Lieutenant Clément Maudet made a stand in the Hacienda de la Trinidad – a farm near the village of Camarone. When only six survivors remained, out of ammunition, a bayonet assault was launched in which three of the six were killed. The remaining three wounded men were brought before the Mexican commander Colonel Milán, who allowed them to return to the French lines as an honor guard for the body of Danjou. The captain had a wooden hand, which was later returned to the Legion and is now kept in a case in the Legion Museum at Aubagne and paraded annually on Camerone Day. It is the Foreign Legion's most precious relic.

During the Mexican Campaign, 6,654 French died. Of these, 1,918 were from a single regiment of the Legion.

According to French law, the Foreign Legion was not to be used within Metropolitan France except in the case of a national invasion, and was consequently not a part of Napoleon III's Imperial Army that capitulated at Sedan. With the defeat of the Imperial Army, the Second French Empire fell and the Third Republic was created.

The new Third Republic was desperately short of trained soldiers following Sedan, so the Foreign Legion was ordered to provide a contingent. On 11 October 1870 two provisional battalions disembarked via sea at Toulon, the first time the Foreign Legion had been deployed in France itself. It attempted to lift the Siege of Paris by breaking through the German lines. It succeeded in retaking Orléans, but failed to break the siege. In January 1871, France capitulated but civil war soon broke out, which led to revolution and the short-lived Paris Commune. The Foreign Legion participated in the suppression of the Commune, which was crushed with great bloodshed.

The Foreign Legion's First Battalion (Lieutenant-Colonel Donnier) sailed to Tonkin in late 1883, during the period of undeclared hostilities that preceded the Sino-French War (August 1884 to April 1885), and formed part of the attack column that stormed the western gate of Sơn Tây on 16 December. The Second and Third Infantry Battalions (chef de bataillon Diguet and Lieutenant-Colonel Schoeffer) were also deployed to Tonkin shortly afterwards, and were present in all the major campaigns of the Sino-French War. Two Foreign Legion companies led the defence at the celebrated Siege of Tuyên Quang (24 November 1884 to 3 March 1885). In January 1885 the Foreign Legion's 4th Battalion (chef de bataillon Vitalis) was deployed to the French bridgehead at Keelung (Jilong) in Formosa (Taiwan), where it took part in the later battles of the Keelung Campaign. The battalion played an important role in Colonel Jacques Duchesne's offensive in March 1885 that captured the key Chinese positions of La Table and Fort Bamboo and disengaged Keelung.

In December 1883, during a review of the Second Legion Battalion on the eve of its departure for Tonkin to take part in the Bắc Ninh Campaign, General François de Négrier pronounced a famous mot: Vous, légionnaires, vous êtes soldats pour mourir, et je vous envoie où l'on meurt! ('You, Legionnaires, you are soldiers in order to die, and I'm sending you to where one dies!')

As part of the Army of Africa, the Foreign Legion contributed to the expansion of the French colonial empire in Sub-Saharan Africa. Simultaneously, the Legion took part to the pacification of Algeria, suppressing various tribal rebellions and razzias.

In 1892, King Béhanzin ordered his soldiers to attack villages near Grand Popo and Porto-Novo (in modern-day Benin) in an effort to reassert the older boundaries of Dahomey. King Béhanzin rejected complaints by the French, who proceeded to declare war

A battalion, led by commandant Faurax Montier, was formed from two companies of the First Foreign Regiment and two others from the second regiment. From Cotonou, the legionnaires marched to seize Abomey, the capital of the Kingdom of Dahomey. Two and a half months were needed to reach the city, at the cost of repeated battles against the Dahomean warriors, especially the Amazons of the King. King Behanzin surrendered and was captured by the legionnaires in January 1894.

In 1895, a battalion formed by the First and Second Foreign Regiments was sent to the Kingdom of Madagascar as part of an expeditionary force whose mission was to conquer the island. The foreign battalion formed the backbone of the column launched on Antananarivo, the capital of Madagascar. After a few skirmishes, Queen Ranavalona III promptly surrendered. The Foreign Legion lost 226 men, only a tenth of whom died during actual combat. Others, like much of the expeditionary force, died from tropical diseases. Despite the success of the expedition, the quelling of sporadic rebellions would take another eight years until 1905, when the island was completely pacified by the French under Joseph Gallieni. During that time, insurrections against the Malagasy Christians of the island, missionaries and foreigners were particularly terrible. Queen Ranavalona III was deposed in January 1897 and was exiled to Algiers in Algeria, where she died in 1917.

From 1882 until his capture, Samori Ture, ruler of the Wassoulou Empire, fought the French colonial army, defeating them on several occasions, including a notable victory at Woyowayanko (2 April 1882), in the face of French heavy artillery. Nonetheless, Samori was forced to sign several treaties ceding territory to the French between 1886 and 1889. Samori began a steady retreat, but the fall of other resistance armies, particularly Babemba Traoré at Sikasso, permitted the colonial army to launch a concentrated assault against his forces. A battalion of two companies from the 2nd Foreign Regiment was created in early 1894 to pacify the Niger. The Legionnaires' victory at the fortress of Ouilla and police patrols in the region accelerated the submission of the tribes. On 29 September 1898, Samori Ture was captured by the French Commandant Gouraud and exiled to Gabon, marking the end of the Wassoulou Empire.

The annexation of Alsace and Lorraine by Germany in 1871 led to numerous volunteers from the two regions enlisting in the Foreign Legion, which gave them the option of French citizenship at the end of their service.

With the declaration of war on 29 July 1914, a call was made for foreigners residing in France to support their adopted country. While many would have preferred direct enlistment in the regular French Army, the only option immediately available was that of the Foreign Legion. On 3 August 1914 a reported 8,000 volunteers applied to enlist in the Paris recruiting office of the Legion.

In World War I, the Foreign Legion fought in many critical battles on the Western Front, including Artois, Champagne, Somme, Aisne, and Verdun (in 1917), and also suffered heavy casualties during 1918. The Foreign Legion was also in the Dardanelles and Macedonian front, and was highly decorated for its efforts. Many young foreigners volunteered for the Foreign Legion when the war broke out in 1914. There were marked differences between the idealistic volunteers of 1914 and the hardened men of the old Legion, making assimilation difficult. Nevertheless, the old and the new men of the Foreign Legion fought and died in vicious battles on the Western front, including Belloy-en-Santerre during the Battle of the Somme, where the poet Alan Seeger, after being mortally wounded by machine-gun fire, cheered on the rest of his advancing battalion.

While suffering heavy casualties on the Western Front the Legion had emerged from World War I with an enhanced reputation and as one of the most highly decorated units in the French Army. In 1919, the government of Spain raised the Spanish Foreign Legion and modeled it after the French Foreign Legion. General Jean Mordacq intended to rebuild the Foreign Legion as a larger military formation, doing away with the legion's traditional role as a solely infantry formation. General Mordacq envisioned a Foreign Legion consisting not of regiments, but of divisions with cavalry, engineer, and artillery regiments in addition to the legion's infantry mainstay. In 1920, decrees ordained the establishment of regiments of cavalry and artillery. Immediately following the armistice the Foreign Legion experienced an increase of enlistments. The Foreign Legion began the process of reorganizing and redeploying to Algeria.

The Legion played a major part in the Rif War of 1920–25. In 1932, the Foreign Legion consisted of 30,000 men, serving in six multi-battalion regiments including the 1st Foreign Infantry Regiment 1 REI – Algeria, Syria and Lebanon; 2nd Foreign Infantry Regiment 2 REI, 3rd Foreign Infantry Regiment 3 REI, and 4th Foreign Infantry Regiment 4 REI – Morocco, Lebanon; 5th Foreign Infantry 5 REI – Indochina; and 1st Foreign Cavalry Regiment 1 REC – Lebanon, Tunisia and Morocco. In 1931, Général Paul-Frédéric Rollet assumed the role of 1st Inspector of the Foreign Legion, a post created at his initiative. While serving as colonel of the 1st Foreign Infantry Regiment (1925–1931), Rollet was responsible for planning the centennial celebrations of the Legion's foundation; scheduling this event for Camarón Day 30 April 1931. He was subsequently credited with creating much of the modern mystique of the Legion by restoring or creating many of its traditions.

The Foreign Legion played a smaller role in World War II in mainland Europe than in World War I, though it saw involvement in many exterior theatres of operations, notably sea-transport protection through to the Norwegian, Syria-Lebanon, and North African campaigns. The 13th Demi-Brigade, formed for service in Norway, found itself in the UK at the time of the French Armistice (June 1940), was deployed to the British 8th Army in North Africa and distinguished itself in the Battle of Bir Hakeim (1942). Reflecting the divisions of the time, part of the Foreign Legion joined the Free French movement while another part served the Vichy government. Germany incorporated German legionnaires into the Wehrmacht's 90th Light Infantry Division in North Africa.

The Syria–Lebanon Campaign of June 1941 saw legionnaire fighting legionnaire as the 13 D.B.L.E clashed with the 6th Foreign Infantry Regiment 6 REI at Damascus. Nevertheless, many legionnaires of the 6th Foreign Infantry Regiment 6 (dissolved on 31 December 1941) integrated into the Marching Regiment of the Foreign Legion R.M.L.E in 1942. Later, a thousand of the rank-and-file of the Vichy Legion unit joined the 13 D.B.L.E. of the Free French forces which were also part (as of September 1944) of Jean de Lattre de Tassigny's successful amalgam of the French Liberation Army (French: Armée française de la Libération), the (400,000 men) amalgam consisted of the Armistice Army, the Free French Forces and the French Forces of the Interior which formed Army B and later became part of the French 1st Army with forces also issued from the French Resistance.

Following World War II, many French-speaking former German soldiers joined the Foreign Legion to pursue a military career, an option no longer possible in Germany, including French German soldiers of Malgré-nous. It would have been considered problematic if the men from Alsace-Lorraine had not spoken French. These French-speaking former German soldiers made up as much as 60 percent of the Legion during the war in Indochina. Contrary to popular belief however, French policy was to exclude former members of the Waffen-SS, and candidates for induction were refused if they exhibited the tell-tale blood type tattoo, or even a scar that might be masking it.

The high percentage of Germans was contrary to normal policy concerning a single dominant nationality, and in more recent times Germans have made up a much smaller percentage of the Foreign Legion's composition.

During the First Indochina War (1946–54) the Foreign Legion saw its numbers swell due to the incorporation of World War II veterans. Although the Foreign Legion distinguished itself in a territory where it had served since the 1880s, it also suffered a heavy toll during this war. Some of the legionnaires, such as Stefan Kubiak, deserted and began fighting for the Việt Minh upon witnessing torture of Vietnamese peasants at the hands of French troops. Constantly being deployed in operations, units of the Legion suffered particularly heavy losses in the climactic Battle of Dien Bien Phu, before the fortified valley finally fell on 7 May 1954.

No fewer than 72,833 served in Indochina during the eight-year war. The Legion suffered the loss of 10,283 of its own men in combat: 309 officers, 1082 sous-officiers and 9092 legionnaires. While only one of several Legion units involved in Indochina, the 1st Foreign Parachute Battalion (1 BEP) particularly distinguished itself, while being annihilated twice. It was renamed the 1st Foreign Parachute Regiment (1 REP) after its third reformation.

The 1 BEP sailed to Indochina on 12 November and was then engaged in combat operations in Tonkin. On 17 November 1950 the battalion parachuted into That Khé and suffered heavy losses at Coc Xa. Reconstituted on 1 March 1951, the battalion participated in combat operations at Cho Ben, on the Black River and in Annam. On 21 November 1953 the reconstituted 1 BEP was parachuted into Dien Bien Phu. In this battle, the unit lost 575 killed and missing. Reconstituted for the third time on 19 May 1954, the battalion left Indochina on 8 February 1955. The 1 BEP received five citations and the fourragère of the colors of the Médaille militaire for its service in Indochina. The 1 BEP became the 1st Foreign Parachute Regiment (1 REP) in Algeria on 1 September 1955.

Dien Bien Phu fell on 7 May 1954 at 17:30. The couple of hectares that were the battlefield today are corn fields surrounding a stele which commemorates the sacrifices of those who died there. While the garrison of Dien Bien Phu included French regular, North African, and locally recruited (Indochinese) units, the battle has become associated particularly with the paratroops of the Foreign Legion.

During the Indochina War, the Legion operated several armoured trains which were an enduring Rolling Symbol during the chartered course duration of French Indochina. The Legion also operated various Passage Companies relative to the continental conflicts at hand.

The legion was heavily engaged in fighting against the National Liberation Front and the Armée de Libération Nationale (ALN). The main activity during the period 1954–1962 was as part of the operations of the 10th Parachute Division and 25th Parachute Division. The 1st Foreign Parachute Regiment, 1 REP, was under the command of the 10th Parachute Division (France), 10 DP, and the 2nd Foreign Parachute Regiment, 2 REP, was under the command of the 25th Parachute Division (France), 25 DP. While both the 1st Foreign Parachute Regiment (1 REP), and the 2nd Foreign Parachute Regiment (2 REP), were part of the operations of French parachute divisions (10 DP and 25 DP established in 1956), the Legion's 1st Foreign Parachute Regiment (1 REP), and the Legion's 2nd Foreign Parachute Regiment (2 REP), are older than the French divisions. The 1 REP was the former thrice-reconstituted 1st Foreign Parachute Battalion (1 BEP) and the 2 REP was the former 2nd Foreign Parachute Battalion (2 BEP). Both battalions were renamed and their Legionnaires transferred from Indochina on 1 August 1954 to Algeria by 1 November 1954. Both traced their origins to the Parachute Company of the 3rd Foreign Infantry Regiment commanded by Legion Lieutenant Jacques Morin attached to the III/1 R.C.P.

With the start of the War in Algeria on 1 November 1954, the two foreign participating parachute battalions back from Indochina, the 1st Foreign Parachute Battalion (1 BEP, III Formation) and the 2nd Foreign Parachute Battalion (2 BEP), were not part of any French parachute divisions yet and were not designated as regiments until September and 1 December 1955 respectively.

Main operations during the Algerian War included the Battle of Algiers and the Bataille of the Frontiers, fought by 60,000 soldiers including French and Legion paratroopers. For paratroopers of the Legion, the 1st Foreign Parachute Regiment (1 REP) and 2nd Foreign Parachute Regiment (2 REP), were the only known foreign active parachute regiments, exclusively commanded by Pierre Paul Jeanpierre for the 1 REP and the paratrooper commanders of the 2 REP. The remainder of French paratrooper units of the French Armed Forces were commanded by Jacques Massu, Buchond, Marcel Bigeard, Paul Aussaresses. Other Legion offensives in the mountains in 1959 included operations Jumelles, Cigales, and Ariège in the Aures and the last in Kabylie.

The image of the Legion as a professional and non-political force was tarnished when the elite 1st Foreign Parachute Regiment 1 REP, which was also part of the 10th Parachute Division played a leading role in the generals' putsch of 1961 and was subsequently disbanded.

Coming out of a difficult Indochinese conflict, the Foreign Legion reinforced cohesion by extending the duration of basic training. Efforts exerted were successful during this transit; however, entering into December 1960 and the generals' putsch, a crisis hit the legion putting its faith at the corps of the Army.

For having rallied to the generals' putsch of April 1961, the 1st Foreign Parachute Regiment of the 10th Parachute Division was dissolved on 30 April 1961 at Zeralda.

In 1961, at the issue of the putsch, the 1st Mounted Saharan Squadron of the Foreign Legion (French: 1 Escadron Saharien Porté de la Légion Etrangère, 1 ESPLE) received the missions to assure surveillance and policing.

The independence of Algeria from the French in 1962 was traumatising since it ended with the enforced abandonment of the barracks command center at Sidi Bel Abbès established in 1842. Upon being notified that the elite regiment was to be disbanded and that they were to be reassigned, legionnaires of the 1 REP burned the Chinese pavilion acquired following the Siege of Tuyên Quang in 1884. The relics from the Legion's history museum, including the wooden hand of Captain Jean Danjou, subsequently accompanied the Legion to France. Also removed from Sidi Bel Abbès were the symbolic Legion remains of General Paul-Frédéric Rollet ( The Father of the Legion ), Legion officer Prince Count Aage of Rosenborg, and Legionnaire Heinz Zimmermann (last fatal casualty in Algeria).

The Legion acquired its parade song "Non, je ne regrette rien" ("No, I regret nothing"), a 1960 Édith Piaf song sung by Sous-Officiers and legionnaires as they left their barracks for re-deployment following the Algiers putsch of 1961. The song has remained a part of Legion heritage since.

The 1st Foreign Parachute Regiment 1 REP was disbanded on 30 April 1961. However, the 2nd Foreign Parachute Regiment 2 REP prevailed in existence, while most of the personnel of the Saharan Companies were integrated into the 1st Foreign Infantry Regiment, 2nd Foreign Infantry Regiment and 4th Foreign Infantry Regiment respectively.

By the mid-1960s the Legion had lost its traditional and spiritual home in French Algeria and elite units had been dissolved. President de Gaulle considered disbanding it altogether but, being reminded of the Marching Regiments, and that the 13th Demi-Brigade was one of the first units to declare for him in 1940 and taking also into consideration the effective service of various Saharan units and performances of other Legions units, he chose instead to downsize the Legion from 40,000 to 8,000 men and relocate it to metropolitan France. Legion units continued to be assigned to overseas service, although not in North Africa (see below).

In the early 1960s, and besides ongoing global rapid deployments, the Legion also stationed forces on various continents while operating different function units.

The main Disciplinary Company of the Foreign Legion (CDLE), based on rules and regulations set by général Rollet in 1931, received serious offenders sent from Legion regiments garrisoned or operating in Algeria, Morocco, Tunisia, the Levant and Tonkin (special section of the 5th Foreign Infantry Regiment and later in 1963, part of a Saharan disciplinary section unit of the 5e REI and 2nd Foreign Infantry Regiment). It was dissolved on July 1, 1964.

From 1965 to 1967, the Legion operated several companies, including the 5th Heavy Weight Transport Company (CTGP), mainly in charge of evacuating the Sahara. The area of responsibility of some of these units extended from the confines of the in-between of the Sahara to the Mediterranean. Ongoing interventions and rapid deployments two years later and the following years included in part:

• 1969–1971 : interventions in Chad
• 1978–present : Peacekeeping operations around the Mediterranean, including the United Nations Interim Force in Lebanon during the Global War on Terror
• 1978–1978 : Battle of Kolwezi (Zaïre)
• 1981–1984 : Peacekeeping operations in Lebanon at the corps of the United Nations Multinational Force during the Lebanese Civil War along with the 31 Brigade which included the 1st Foreign Regiment 1 RE. Operation Épaulard I was spearheaded by Lieutenant-colonel Bernard Janvier. The Multinational Force also included the British Armed Forces 1st The Queen's Dragoon Guards, U.S. American contingents of United States Marine Corps and the United States Navy, the French Navy and 28 exclusive French Armed Forces regiments including French paratroopers regiments, companies, units of the 11th Parachute Brigade along with the 2nd Foreign Parachute Regiment 2 REP. The multinational force also included the Irish Armed Forces and units of the French National Gendarmerie, Italian paratroopers from the Folgore Brigade, and infantry units from the Bersaglieri regiments and Marines of the San Marco Battalion.

In September 1990, the 1st Foreign Regiment, the 1st Foreign Cavalry Regiment, the 2nd Foreign Parachute Regiment, the 2nd Foreign Infantry Regiment, and the 6th Foreign Engineer Regiment were sent to the Persian Gulf as a part of Opération Daguet along with the 1st Spahi Regiment, the 11th Marine Artillery Regiment, the 3rd Marine Infantry Regiment, the 21st Marine Infantry Regiment, the French Army Light Aviation, the Régiment d'infanterie-chars de marine, and components of the 35th Parachute Artillery Regiment, the 1st Parachute Hussard Regiment, and the 17th Parachute Engineer Regiment. Division Daguet was commanded by Général de brigade Bernard Janvier.

The Legion force, made up of 27 different nationalities, was attached to the French 6th Light Armoured Division whose mission was to protect the Coalition's left flank.

After the four-week air campaign, coalition forces launched the ground offensive. They quickly penetrated deep into Iraq, with the Legion taking the As-Salman Airport, meeting little resistance. The war ended after a hundred hours of fighting on the ground, which resulted in very light casualties for the Legion. During war, French Foreign Legion engineers operated in support of the U.S. Army's 82nd Airborne Division, and provided the EOD services to the division. After the ceasefire, they conducted a joint mine clearing operation with a Royal Australian Navy clearance divers.

Regarding the operational aspect, the units of the Legion belong to different brigades or territorial commands of the French Army. On the other hand, with regard to the administrative management (including recruitment, traditions and training), these units depend on the Foreign Legion Command (COMLE), which itself is subordinate to the Army.

The regiments are now mainly stationed in Metropolitan France, with some units in the overseas departments and territories (mainly in French Guiana).
