Königsberg [SEP] Introduction
Königsberg (, , ) is the name for the historic Prussian city that is now Kaliningrad, Russia. Originally a Sambian or Old Prussian settlement, it then belonged to the State of the Teutonic Order, the Duchy of Prussia, the Kingdom of Prussia, the German Empire, the Weimar Republic, and Nazi Germany. After being largely destroyed in World War II by Allied bombing and the Red Army, it was annexed by the Soviet Union and its surviving inhabitants forcibly expelled. Thereafter, the city was renamed Kaliningrad. Few traces of the former Königsberg remain today. The literal meaning of Königsberg is 'King's Mountain'.
