Since the 18th century Berlin has been an influential musical center in Germany and Europe. First as an important trading city in the Hanseatic League, then as the capital of the electorate of Brandenburg and the Prussian Kingdom, later on as one of the biggest cities in Germany it fostered an influential music culture that remains vital until today. Berlin can be regarded as the breeding ground for the powerful choir movement that played such an important role in the broad socialization of music in Germany during the 19th century.
