Polish Corridor

The Polish Corridor (German: Polnischer Korridor; Polish: korytarz polski), also known as the Pomeranian Corridor, was a territory located in the region of Pomerelia (Pomeranian Voivodeship, Eastern Pomerania), which provided the Second Polish Republic with access to the Baltic Sea, thus dividing the bulk of Weimar Germany from the province of East Prussia. At its narrowest point, the Polish territory was just 30 km (19 mi) wide. The Free City of Danzig (now the Polish cities of Gdańsk, Sopot and the surrounding areas), situated to the east of the corridor, was a semi-independent German speaking city-state forming part of neither Germany nor Poland, though united with the latter through an imposed union covering customs, mail, foreign policy, railways as well as defence. It was under the protection of the League of Nations. After Poland lost Western Pomerania to Germany in the late 13th century, the area of Eastern Pomerania with the strategically important port of Gdańsk remained a narrow strip of land giving Poland access to the Baltic Sea and was also sometimes referred to as Pomeranian corridor.
