Erlangen is a Middle Franconian city in Bavaria, Germany. It is located at the confluence of the river Regnitz and its large tributary, the Untere Schwabach. Erlangen has more than 100,000 inhabitants.
Erlangen is today dominated by the University of Erlangen-Nuremberg and the numerous branch offices of Siemens AG, as well as a large Institute of the Fraunhofer Society. An event that still influences the city was the settlement of Huguenots after the withdrawal of the Edict of Nantes in 1685.
While being part of the Brandenburg-Bayreuth, the first French Huguenot refugees arrived in Erlangen in 1686. Christian Ernst, Margrave of Brandenburg-Bayreuth, built a "new town" (Neustadt) for them. In 1706, the old town (just below the site of the annual Bergkirchweih) was almost completely destroyed by a fire, but soon rebuilt. In 1812, the old and new towns were merged into one.
In 1742, Frederick, Margrave of Brandenburg-Bayreuth, founded a university for the residency town Bayreuth, but due to the rebelliousness of the local students, the university was transferred to Erlangen. Only later did it obtain the name of "Friedrich-Alexander-University" and become a Prussian state university. Famous students of these times were Johann Ludwig Tieck and Wilhelm Heinrich Wackenroder.
Already during the Bavarian municipal reform of 1818, the city was endowed with its own administration. In 1862, the canton administration Erlangen was founded, from which later arose the administrative district of Erlangen. In 1972, this district was merged with the administrative district of Höchstadt. Erlangen became the capital of this newly founded district Erlangen-Höchstadt. During this municipal reform, Erlangen was effectively enlarged considerably, so that by 1974, it had more than 100,000 inhabitants.
The University of Erlangen-Nuremberg (Friedrich-Alexander-Universität,
) was founded in 1742 by Frederick, Margrave of Brandenburg-Bayreuth, in the city of Bayreuth, but was relocated to Erlangen the next year. Today, it features 11 departments (German "Fakultäten"), 2 of which (Economics and Education) are located in Nuremberg. About 24,000 students study at this university, of which about 20,000 are located in Erlangen.
It is commonly known by local residents as the "Berchkärwa" (pronounced "bairch'-care-va") or simply the "Berch", as in "Gehma auf'm Berch?" ("Let's go to the mountain?").
