List of rulers of Lithuania
The state of Lithuania formed in the 1230s, when threatened by the Livonian Order in the north and the Teutonic Knights in the west, the Baltic tribes united under the leadership of Mindaugas. He became the only crowned king of Lithuania. His state became known as Grand Duchy of Lithuania. After Grand Duke Jogaila became also king of Poland in 1386, the two states became closer connected and since 1440 both were ruled by a common ruler. In 1569 Union of Lublin was signed and a new entity—the Polish–Lithuanian Commonwealth—emerged. The commonwealth was partitioned in 1795 and Lithuania became part of the Russian Empire till 16 February 1918. The Council of Lithuania was able to establish the sovereignty only in 1919, after Germany lost World War I. The first republic of Lithuania existed until 1940 when it was occupied by the Soviet Union. During the Soviet-German War, Lithuania was occupied by Nazi Germany. In 1944, as Germany was losing the war, Russia re-occupied Lithuania and established the Lithuanian Soviet Socialist Republic. On 11 March 1990, Lithuania became the first Soviet republic to declare independence. The restored Republic of Lithuania is a democratic republic, a member of both the European Union and NATO.
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.
