Polish Corridor, Geopolitical corridor between East Prussia and Germany, Poland
The Polish Corridor was a strip of land in West Prussia that gave Poland access to the Baltic Sea after World War I and separated East Prussia from the rest of German territory. The area ran along the Vistula from the Pomeranian coast to the border near Bydgoszcz and included numerous towns and villages with mixed populations.
The Allies transferred the territory to Poland in 1919 to secure sea access for the restored state. Germany lost parts of West Prussia and Posen province as well as direct land connection to East Prussia.
The region contained both Polish and German populations during the interwar period, with Poles forming the majority in rural areas and Germans in urban centers.
The former corridor region today covers large parts of the Polish Pomeranian Voivodeship and extends from the coast inland. Travelers crossing the area pass through landscapes with rivers, forests, and historical towns along the old border lines.
Poland built the port of Gdynia practically from scratch in the 1920s because Danzig was under League of Nations administration and offered no guarantee of Polish sovereignty. Within a few years the new port grew into one of the largest Baltic Sea harbors and competed directly with neighboring Danzig.
