Lithuania took advantage of the Ruhr Crisis in western Europe and captured the Klaipėda Region, a territory detached from East Prussia by the terms of the Treaty of Versailles and placed under a French administration sponsored by the League of Nations. The region was incorporated as an autonomous district of Lithuania in May 1924. For Lithuania, it provided the country's only access to the Baltic Sea, and it was an important industrial center, but the region's numerous German inhabitants resisted Lithuanian rule during the 1930s. The Klaipėda Revolt was the last armed conflict in Lithuania before World War II.
