> Just to add... capitol of Prussia after 1871. Before 1871, the capitol of > Prussia was located in Ostpreussen (East Prussia). sorry, wrong. Prussia was a grand duchy from 1525 until 1701. The kingdom of Prussia was formed in 1701 and existed until 1918, the state of Prussia from 1918 until 1947. The capital of all three was Berlin. Koenigsberg in East Prussia remained the city of the coronation of the Prussian dukes and later kings and was made the capital of the province of Prussia, formed out of East and West Prussia in 1829, both being just one part of the kingdom of Prussia which included much more of Germany Chris
