The Province of Pomerania was a province of Prussia from 1815 to 1945. Pomerania was established as a province of the Kingdom of Prussia in 1815, an expansion of the older Brandenburg-Prussia province of Pomerania, and then became part of the German Empire in 1871. From 1918, Pomerania was a province of the Free State of Prussia until it was dissolved following World War II by decree of the Allied Control Council with the de jure abolition of Prussia on 25 February 1947, and its territory divided between Poland and Allied-occupied Germany. The city of Stettin was the provincial capital.

Prussia was a German state located on most of the North European Plain, also occupying southern and eastern regions. It formed the German Empire when it united the German states in 1871. It was de facto dissolved by an emergency decree transferring powers of the Prussian government to German Chancellor Franz von Papen in 1932 and de jure by an Allied decree in 1947. For centuries, the House of Hohenzollern ruled Prussia, expanding its size with the Prussian Army. Prussia, with its capital at Königsberg and then, when it became the Kingdom of Prussia in 1701, Berlin, decisively shaped the history of Germany.
