Western Pomerania

Western Pomerania or Cispomerania, Hither Pomerania is the English term for German Vorpommern, the western extremity of the historic region of the duchy, later Province of Pomerania, nowadays divided between the German state of Mecklenburg-Vorpommern and Poland.

The name Pomerania comes from Slavic po more, which means Land at the Sea. The adjective for the region is (Western) Pomeranian (Polish: pomorski, German: pommersch), inhabitants are called (Western) Pomeranians (Polish: Pomorzanie, German: Pommern).

Forming part of the southern coast of the Baltic Sea, Western Pomerania's boundaries have changed through the centuries and it belonged to countries such as Poland, Sweden, Denmark, and Prussia. Before 1945, it embraced the whole area of Pomerania west of the Oder River. Today the cities of Szczecin (German: Stettin), Świnoujście (German: Swinemünde) and Police (German: Pölitz) are part of Poland (see Territorial changes of Poland immediately after World War II), with the remainder of the region staying part of Germany. German Vorpommern now forms about one-third of the present-day north-eastern state of Mecklenburg-Vorpommern.
