The military occupation of Lithuania by Nazi Germany lasted from the German invasion of the Soviet Union on June 22, 1941, to the end of the Battle of Memel on January 28, 1945. At first the Germans were welcomed as liberators from the repressive Soviet regime which had occupied Lithuania. In hopes of re-establishing independence or regaining some autonomy, Lithuanians had organized a Provisional Government. It lasted six weeks.

Lithuania, officially the Republic of Lithuania, is a country in the Baltic region of Europe. It is one of three Baltic states and lies on the eastern shore of the Baltic Sea.
