German is not the world’s first and most important language. It is not spoken by as many people as Spanish; but, it is an important language and to learn, especially in fields of science and medicine. Speaking it will give you a leg up on your peers.
Over 95% of Germans speak German or German dialects. There are 4 main minority languages, each spoken by less than 1% of the population : Sorbani, Romain, Danish, and North Frisian.
Many Germans also speak English, French, Latin, Dutch, and Russian as a second language.
First-generation immigrants may, of course, speak the languages of their former countries. This includes over 2 million Turkish immigrants.
Germany was united into a central government in 1871, under the leadership of Prussia. Berlin was also the capital of the Kingdom after 1918 in the State of Prussia. Then, in 1949, after the formation of Federal Republic of Germany (West Germany) Bonn was chosen as the new capital, while East Berlin became the capital of the rival German Democratic Republic (East Germany). When Germany was reunited in 1990 Berlin was formally proclaimed the Federal Capital ('Bundeshauptstadt'). Berlin had a special status in international law, at least nominally, from 1945-90.
The city has a very rich history but also offers the latest in art, architecture and fashion. Berlin is changing constantly and there will always be something new to explore.
Since late March 2002 the only legal tender currency in Germany has been the Euro (€) . The Deutschmark is no longer legal tender.
