Outline of Lithuania
During the 14th century, Lithuania was the largest country in Europe, as present-day Belarus, Ukraine, and parts of Poland and Russia were territories of the Grand Duchy of Lithuania. With the Lublin Union of 1569 Poland and Lithuania formed a new state: the Polish–Lithuanian Commonwealth, which was finally destroyed by its neighboring countries in 1795. Most of Lithuania's territory was annexed by the Russian Empire, until the Act of Independence was signed on 16 February 1918, which declared re-establishment of a sovereign state. Between 1940 and 1945 Lithuania was occupied by both the Soviet Union and Nazi Germany at different times. When World War II was near its end in 1944 and the Nazis retreated, the Soviet Union reoccupied Lithuania. On 11 March 1990, Lithuania became the first Baltic republic to declare its restored independence after 50 years of Soviet occupation.
Lithuania became a full member of the Schengen Agreement on 21 December 2007. In 2009, Lithuania celebrated the millennium of its name.Geography of Lithuania
Lithuania
As a result of the Great Retreat during World War I, Germany occupied the entire territory of Lithuania and Courland by the end of 1915. A new administrative entity, Ober Ost, was established. Lithuanians lost all political rights they had gained: personal freedom was restricted, and at the beginning the Lithuanian press was banned. However, the Lithuanian intelligentsia tried to take advantage of the existing geopolitical situation and began to look for opportunities to restore Lithuania's independence. On 18–22 September 1917, the Vilnius Conference elected the 20-member Council of Lithuania. The council adopted the Act of Independence of Lithuania on 16 February 1918 which proclaimed the restoration of the independent state of Lithuania governed by democratic principles, with Vilnius as its capital. The state of Lithuania which had been built within the framework of the Act lasted from 1918 until 1940.
Following the capitulation of Germany in November 1918, the first Provisional Constitution of Lithuania was adopted and the first government of Prime Minister Augustinas Voldemaras was organized. At the same time, the army and other state institutions began to be organized. Lithuania fought three wars of independence: against the Bolsheviks who proclaimed the Lithuanian Soviet Socialist Republic, against the Bermontians, and against Poland. As a result of the staged Żeligowski's Mutiny in October 1920, Poland took control of Vilnius Region and annexed it as Wilno Voivodeship in 1922. Lithuania continued to claim Vilnius as its "de jure" capital and relations with Poland remained particularly tense and hostile for the entire interwar period. In January 1923, Lithuania staged the Klaipėda Revolt and captured Klaipėda Region (Memel territory) which was detached from East Prussia by the Treaty of Versailles. The region became an autonomous region of Lithuania.
