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.
Council of Lithuania
The Council of Lithuania (, , ), after July 11, 1918 the State Council of Lithuania () was convened at the Vilnius Conference that took place between 18 and 23 September 1917. The twenty men who composed the council at first were of different ages, social status, professions, and political affiliations. The council was granted the executive authority of the Lithuanian people and was entrusted to establish an independent Lithuanian state. On 16 February 1918, the members of the council signed the Act of Independence of Lithuania and declared Lithuania an independent state based on democratic principles. 16 February is celebrated as Lithuania's State Restoration Day. The council managed to establish the proclamation of independence despite the presence of German troops in the country until the autumn of 1918. By the spring of 1919, the council had almost doubled in size. The council continued its efforts until the Constituent Assembly of Lithuania () first met on 15 May 1920.
