The commonwealth was partitioned in 1795 and Lithuania became part of the Russian Empire till 16 February 1918. The Council of Lithuania was able to establish the sovereignty only in 1919, after Germany lost World War I. The first republic of Lithuania existed until 1940 when it was occupied by the Soviet Union. During the Soviet-German War, Lithuania was occupied by Nazi Germany. In 1944, as Germany was losing the war, Russia re-occupied Lithuania and established the Lithuanian Soviet Socialist Republic.
