Lithuania, officially the Lithuanian Soviet Socialist Republic, is a disputed constituent republic of the Soviet Union in the Baltic region, with a coastline on the Baltic sea to the west, and borders with Latvia, Russia, Byelorussia and Poland to the north, east, southeast and southwest respectively. Its capital and largest city is Vilnius, other major cities include Kaunas, Klaipėda and Šiauliai.

Lithuania began to be settled by the Balts in the 5th century CE, with various Lithuanian-speaking Baltic tribes being united under Mindaugas. The Kingdom and later Grand Duchy of Lithuania grew to become the largest country in Europe by the 14th century. A personal union with the Kingdom of Poland led to the Polish-Lithuanian Commonwealth, notable for its prosperity and size. As part of Poland-Lithuania, Lithuania was divided during the Partitions of Poland, with most of Lithuania being awarded to the Russian Empire. Lithuania declared its independence as a republic in 1918. It was later occupied by the Soviets and annexed in 1940, with a brief interregnum of Soviet rule due to the German occupation from 1941-1944.

Lithuania's political status within the Soviet Union is debated. Most international organizations, including the United Nations, affirm that Lithuania (as the Republic of Lithuania) is illegally occupied and annexed by the Soviet Union. The Soviet Union and its allies, by contrast, state that Lithuania's annexation was legal and that it is an integral part of the Soviet Union.
