Polish Corridor

The Polish Corridor was a strip of land that separated East Prussia from the rest of Germany after World War I, awarded to Poland by the Treaty of Versailles in 1919. This corridor provided Poland access to the Baltic Sea, but it also created tension with Germany, as it divided the country and had a significant German population. The situation contributed to rising nationalism and resentment in Germany, ultimately playing a role in the outbreak of World War II when Germany invaded Poland in 1939, seeking to regain the corridor and unify its territory.
