Polish Corridor , strip of land, 32 to 112 km wide, belonging to the newly restored Polish state after the First World War Access to Baltic Sea provided . The corridor was on the lower reaches of the Vistula and consisted of West Prussia and most of the province poses (poses) that the Treaty of Versailles (1919) transferred from defeated Germany after Poland . Perhaps no provision of the treaty caused so much hostility and resentment among the Germans like this regulation, because the corridor ran between Pomeranian and East Prussia and separated the latter province from the main body of the German Empire to the west. On the other hand, it should be noted that (1) the area was historically Polish (ie prior to the partitions of Poland in the late 18th century) and inhabited by a Polish majority; (2) the determination that starts with the 13th of fourteen points from US President Woodrow Wilson matches to grant Poland "free and safe access to the sea" and indeed its only access; and (3) the ceded territory did not include Gdańsk (Gdańsk), then a purely German city, established as a free city under the Sovereignty des League of Nations . Poland developed the corridor port of Gdynia as Alternative to Gdansk. Free German transit was allowed through the corridor.
The Polish corridor was the subject, or at least the obvious pretext, about which the World War II started. In March 1939, Germany became the Nazi dictator, Adolf Hitler demanded the cession of Danzig and the creation of extraterritorial German autobahns across the corridor to East Prussia. Poland rejected these demands and secured French and British guarantees against German aggression. In September, Germany invaded Poland, starting the war. Hitler annexed the Polish Corridor, Danzig, Posen and districts along the Silesian border and placed the rest of the conquered Polish territory under a German governor. But after World War II, the entire area was re-mapped with large shifts in German and Polish populations, and the problem disappeared when the Polish Corridor, along with Gdańsk and East Prussia, became part of post-war Poland was.
