Liberec (Czech: [ˈlɪbɛrɛts] ; German: Reichenberg) is a city in the Czech Republic. It has about 108,000 inhabitants, making it the fifth largest city in the country. It lies on the Lusatian Neisse River, in a basin surrounded by mountains. The city centre is well preserved and is protected by law as an urban monument zone.

Liberec was once home to a thriving textile industry and hence nicknamed the "Manchester of Bohemia". For many Czechs, Liberec is mostly associated with the city's dominant Ještěd Tower. Since the end of the 19th century, the city has been a conurbation with the suburb of Vratislavice nad Nisou and the neighbouring city of Jablonec nad Nisou.

Liberec is made up of 32 city parts and one self-governing borough (Vratislavice nad Nisou):

In the early 1990s, some parts became independent municipalities: Stráž nad Nisou (formerly Liberec XXVI-Stráž nad Nisou and Liberec XXVII-Svárov), Dlouhý Most (formerly Liberec XXXVI-Dlouhý Most), Jeřmanice (formerly Liberec XXXVII-Jeřmanice) and Šimonovice (formerly Liberec XXXVIII-Minkovice and Liberec XXXIX-Šimonovice).

The oldest known names of the city are German, Reychinberch (1352) and Reychmberg (1369), meaning "rich/resourceful mountain" (reicher Berg in modern German). It was also spelled Reichenberg (1385–1399) and Rychmberg (1410).

The Czech equivalent originated as a distortion: Rychberk (1545), Libercum (1634), Liberk (1790), and finally Liberec (1845). In Czech, words starting with "R" were often dissimilated into "L". Since then, the city was known as Liberec in Czech and as Reichenberg in German.

Liberec is located about 80 kilometres (50 mi) northeast of Prague. Most of the municipal territory lies in the Zittau Basin. In the northeast, the territory extends into the Jizera Mountains and to the eponymous protected landscape area. In the west, the territory extends into the Ještěd–Kozákov Ridge and includes the highest point of Liberec and of the entire Ještěd–Kozákov Ridge, the mountain Ještěd at 1,012 m (3,320 ft) above sea level.

Liberec is situated on the Lusatian Neisse River. The largest body of water is Harcov Reservoir (also called Liberec Dam). The reservoir is located inside the built-up area on the Lusatian Neisse's tributary, the stream of Harcovský potok. Today it serves mainly as a recreational place for the residents of Liberec, but it was originally designed to protect the city from floods and as a water reservoir for industrial use. It is also important as a biotope with the occurrence of protected animals.

Liberec has a humid continental climate (Köppen Dfb). The annual average temperature is 8.3 °C (46.9 °F), the hottest month in July is 18.0 °C (64.4 °F), and the coldest month is −1.2 °C (29.8 °F) in January. The annual precipitation is 845.3 millimetres (33.28 in), of which July is the wettest with 107.1 millimetres (4.22 in), while April is the driest with only 41.3 millimetres (1.63 in). The extreme temperature throughout the year ranged from −24.6 °C (−12.3 °F) on 14 January 1987 to 36.2 °C (97.2 °F) on 31 July 1994.

In the 11th or 12th century, a settlement named Habersdorf, which was the predecessor of Liberec, was established on the trade route from Bohemia to Lusatia by Czech settlers and German colonizers. In the 13th century, a second settlement named Reichenberg was established near the first one. The two settlements later merged. The first written mention of Liberec under its German name Reichenberg is from 1352.

Starting in 1278, the area was owned by the noble Bieberstein family. Reichenberg suffered from the passing through of troops during the Hussite Wars, then was burned down in 1469 during a battle with the army of King George of Poděbrady. After the Biebersteins died out, the Frýdlant estate, which included Reichenberg, was bought by the Redern family in 1558. The Rederns contributed significantly to the development of the settlement, as they built new buildings, modernized the settlement and laid the foundation of the textile industry. In 1577, Reichenberg was promoted to a town by Emperor Rudolf II. He gave the town the coat of arms it still uses today.

From 1600, the town was administered by Kateřina of Redern, who obtained the right to trade in salt for the town, had a chapel added to the castle and contributed to the construction of the town hall. When the Redern family was forced to leave Reichenberg after the Battle of White Mountain (1620), it was acquired by Albrecht von Wallenstein. After his death it belonged to the Gallas and Clam Gallas families, who did not care much about the town. The prosperous local industry was interrupted by the Thirty Years' War and a great plague in 1680. The crises resulted in a series of harshly suppressed serf uprisings.

In the 18th century, Reichenberg flourished. The number of inhabitants tripled and the cloth industry was very successful. The Battle of Reichenberg between Austria and Prussia occurred nearby in 1757 during the Seven Years' War, but the town continued to develop. During the 19th century, the town became the centre of textile industry in the entire Austria-Hungary. In 1850, it became a self-governing city.

Reichenberg became a rich industrial city without representative buildings. In the late 19th century, a spectacular collection of representative buildings was created, mostly in the neo-Renaissance style: the city hall, the opera house, the North Bohemian Museum, the Old Synagogue, and others. A representative villa district and a forest with a botanical garden and a zoo were created.

Until 1918, the city was part of Austria-Hungary, seat of the Reichenberg district, one of the 94 Bezirkshauptmannschaften in Bohemia. After the end of World War I, Austria-Hungary fell apart and the Czechs of Bohemia joined newly established Czechoslovakia on 29 October 1918 whilst the Germans wanted to stay with Austria to form reduced German Austria on 12 November 1918, both citing Woodrow Wilson's Fourteen Points and the doctrine of self-determination. Liberec was declared the capital of the German-Austrian province of German Bohemia. Czechs however argued that these lands, though German-settled since the Middle Ages, were historically an integral part of the Duchy and Kingdom of Bohemia. On 16 December 1918, the Czechoslovak Army entered Liberec and the whole province remained part of Bohemia.

The Great Depression devastated the economy of the area with its textile, carpet, glass and other light industry. The high number of unemployed people, hunger, fear of the future and dissatisfaction with the Prague government led to the flash rise of the populist Sudeten German Party (SdP), founded by Konrad Henlein, born in the suburbs of Liberec. The city became the centre of Pan-German movements and later of the Nazis, especially after the 1935 election, despite its important democratic mayor, Karl Kostka (German Democratic Freedom Party). The final change came in Summer 1938, after the radicalization of the terror of the SdP, whose death threats forced Kostka and his family to flee to Prague.

In September 1938, the Munich Agreement awarded the city to Nazi Germany. In 1939, it became the capital of Reichsgau Sudetenland. Most of the city's Jewish and Czech population fled to the rest of Czechoslovakia or were expelled. The important synagogue was burned down. Henlein himself confiscated a villa in Liberec that had belonged to a Jewish businessman, which remained Henlein's home until 1945.

After World War II, the city again became a part of Czechoslovakia and nearly all of the city's German population was expelled following the Beneš decrees. The region was then resettled with Czechs.
