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.
Vilnius Conference
The Vilnius Conference or Vilnius National Conference () met between September 18, 1917 and September 22, 1917, and began the process of establishing a Lithuanian state based on ethnic identity and language that would be independent of the Russian Empire, Poland, and the German Empire. It elected a twenty-member Council of Lithuania that was entrusted with the mission of declaring and re-establishing an independent Lithuania. The Conference, hoping to express the will of the Lithuanian people, gave legal authority to the Council and its decisions. While the Conference laid the basic guiding principles of Lithuanian independence, it deferred any matters of political structure of the future Lithuania to the Constituent Assembly, which would later be elected in a democratic manner.
