History of Lithuania
On February 16, 1918, Lithuania was re-established as a democratic state. It remained independent until the outset of World War II, when it was occupied by the Soviet Union under the terms of the Molotov–Ribbentrop Pact. Following a brief occupation by Nazi Germany after the Nazis waged war on the Soviet Union, Lithuania was again absorbed into the Soviet Union for nearly 50 years. In 1990–1991, Lithuania restored its sovereignty with the Act of the Re-Establishment of the State of Lithuania. Lithuania joined the NATO alliance in 2004 and the European Union as part of its enlargement in 2004.
History of Lithuania
The Lithuanian state of the later 14th century was primarily binational, Lithuanian and Ruthenian (in territories that correspond to the modern Belarus and Ukraine). Of its 800,000 square kilometers total area, 10% comprised ethnic Lithuania, probably populated by no more than 300,000 inhabitants. Lithuania was dependent for its survival on the human and material resources of the Ruthenian lands.
