Jena (pronunciation IPA: [ˈjeːna]) is a university city in central Germany on the river Saale. With a population of 102,494, it is the second largest city in the federal state of Thüringen (Thuringia), after Erfurt.
Jena was first mentioned in an 1182 document. In the 11th century it was a possession of the lords of Lobdeburg, but in the following century it developed into an independent market town with laws and magistrates of its own. Economy was based mainly on wine production. In 1286 the Dominicans were established in the city, followed by the Cistercians in 1301.
The margraves of Meißen imposed their authority over Jena in 1331. From 1423 it belonged to Electoral Saxony of the Housen of Wettin, who had inherited Meißen, remaining with it also after the division of their lands in 1485.
For a short period (1670-1690), Jena was the capital of an independent dukedom (Saxe-Jena). In 1692 it was annexed to Saxe-Eisenach and in 1741 to the Duchy (later Grand Duchy) of Saxe-Weimar, to which it belonged until 1918.
At the end of the 19th century, with the building of the railway-line Saalbahn (along the river Saale), Jena became a center for precision machinery, optics and glass making, with the formation of the world famous companies Carl Zeiss Jena and Schott Jenaer Glaswerk, by Carl Zeiss, Ernst Abbe and Otto Schott.
In 1945, towards the end of World War II, Jena was heavily bombed by the American and British Allies. 153 people were killed and most of the medieval town centre was destroyed (though restored after the end of the war).
Today Jena is a manufacturing city, specializing in precision machinery, pharmaceuticals, optics and photographic equipment, and is home to the famous Zeiss optics plant. In 1926, the world's first modern planetarium was built by the Zeiss company in the Damenviertel district of the town.
Today the city's economy diversifies into bioinformatics, biotechnology, software and photonics. The metropolitan area of Jena is among Germany's 50 fastest growing regions, with many internationally renowned research institutes and companies, a comparatively low unemployment, and a very young population structure. Jena was awarded with the title "Stadt der Wissenschaft" (city of science) by the Stifterverband für die Deutsche Wirtschaft, the German business association, in 2008.
