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.
History of Lithuania
The Constituent Assembly of Lithuania was elected in April 1920 and first met the following May. In June it adopted the third provisional constitution and on July 12, 1920, signed the Soviet–Lithuanian Peace Treaty. In the treaty the Soviet Union recognized fully independent Lithuania and its claims to the disputed Vilnius Region; Lithuania secretly allowed the Soviet forces passage through its territory as they moved against Poland. On July 14, 1920, the advancing Soviet army captured Vilnius for a second time from Polish forces. The city was handed back to Lithuanians on August 26, 1920, following the defeat of the Soviet offensive. The victorious Polish army returned and the Soviet–Lithuanian Treaty increased hostilities between Poland and Lithuania. To prevent further fighting, the Suwałki Agreement was signed with Poland on October 7, 1920; it left Vilnius on the Lithuanian side of the armistice line. It never went into effect, however, because Polish General Lucjan Żeligowski, acting on Józef Piłsudski's orders, staged the Żeligowski's Mutiny, a military action presented as a mutiny. He invaded Lithuania on October 8, 1920, captured Vilnius the following day, and established a short-lived Republic of Central Lithuania in eastern Lithuania on October 12, 1920. The "Republic" was a part of Piłsudski's federalist scheme, which never materialized due to opposition from both Polish and Lithuanian nationalists.
