The Old Prussian (in German Altpreußisch) is a Baltic language spoken in ancient Prussia (East Prussia), originally the Königsberg area (today Kaliningrad), a Russian enclave between Poland and Lithuania. The language has not been spoken since the 17th century.
Prussia gradually became German. Then the name was extended to the Kingdom of Prussia, later including Brandenburg, whose capital is Berlin. Prussian can also designate the dialect of Lower German spoken in Prussia.
