The foundation of Berlin was very multicultural. The surrounding area was populated by Germanic Swabian and Burgundian tribes, as well as Slavic Wends in pre-Christian times, and the Wends have stuck around. Their modern descendants are the Sorbian Slavic-language minority who live in villages southeast of Berlin near the Spree River. In the beginning of the 13th century, two towns (Berlin and C??lln) developed on each side of the river Spree (today the Nikolaiviertel and the quarter next to it beyond the river). As the population grew, the towns merged and Berlin became a center for commerce and agriculture. This area stayed small (about 10,000 inhabitants) up to the late 17th century, because of the 30 years' war in the beginning of the 17th century, which led to death of about half of the population. Since the the late 17th century, when large numbers of French Huguenots fled religious persecution, Berlin has welcomed religious, economic and other asylum seekers. 1701 Berlin became the capital of Prussia and in 1710 Berlin and surrounding former autonomous cities were merged to a bigger Berlin. In 1871 Berlin became the capital of the new founded German Reich and a few years later, it became a city with more than one million inhabitants because of the immensely growing industry. Shortly after the first World War, in 1920, the last of the annexations of surrounding cities of Berlin led to the foundation of the Berlin as we know it now. After the coming into power of the National Socialists, Berlin became the capital of the so called Third Reich and the domicile and office of Hitler (though the triumph of Hitler and his companions started in the south of Germany). WW II led to destruction of most of central Berlin, thus many of the buildings which we see nowadays are reconstructed or planned and built after the war, which led to a very fragmented cityscape in most parts of the inner town. Berlin was divided into four sectors (West Berlin into the French, American and British sector, East Berlin belonged to the USSR). In 1949 the GDR was founded with East Berlin as its capital - West Berlin belonged to West Germany (with Bonn as the capital) and was an exclave (political island) in East Germany. Because of the growing tensions between West Germany and the GDR, the latter built a wall between the countries and around West Berlin, so the division was complete. In 1989 the German revolution took place -subsequently leading to the fall of the Berlin Wall- and in 1990 West and East Germany were merged officially together with Berlin becoming the capital of reunified Germany. After WW II and the building of the wall, large numbers of immigrants from Turkey were invited to West Berlin to work in the growing industry sector; in East Berlin the jobs were done mostly by Vietnamese immigrants. But also people from other communist countries, including the former Yugoslavia, not to mention Soviet soldiers who refused to return home, have helped to make Berlin more multicultural than ever. Berlin is also a youth-oriented city. Before German unification, West Berliners were exempt from the West German civil/military service requirement. Social activists, pacifists and anarchists of all moved to Berlin for that reason alone. Musicians and artists were given state subsidies. It was easy to stay out all night thanks to liberal bar licensing laws, and staying at university for years without ever getting a degree was a great way to kill time. In contrast with most of Germany, Prenzlauer Berg is said to have the highest per-capita birth rate in Europe (in fact it just seems so because of the high percentage of young women in the district). After the fall of the wall, Berlin - especially the former East - has evolved into a cultural mecca. Artists and other creative souls flocked to the city in swarms after reunification, primarily due to the extremely low cost of living in the East. Despite the increased prices and gentrification as a result, Berlin has become a center for art, design, multimedia, electronic music, and fashion a
