Prussia was a German kingdom and historic state originating out of the Duchy of Prussia and the Margraviate of Brandenburg, and centered on the region of Prussia. For centuries, the House of Hohenzollern ruled Prussia, successfully expanding its size by way of an unusually well-organised and effective army. Prussia, with its capital in Berlin after 1451, shaped the history of Germany. In 1871, German states united in creating the German Empire under Prussian leadership. In November 1918, the monarchies were abolished and the nobility lost its political power. Prussia was effectively abolished in 1932, and officially abolished in 1947
