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.
Lithuania Minor
Lithuania declared its independence from Russia in 1918 during World War I. Some Prussian Lithuanian activists signed the Act of Tilsit, demanding unification of Lithuania Minor and Lithuania major into a single Lithuanian state, thus detaching the areas of East Prussia from Germany which were inhabited by Prussian Lithuanians. This claim was supported by the Lithuanian government. The part north of the Neman River up to Memel was separated from Germany by the Treaty of Versailles in 1920, and was called the Memel Territory. It was made a protectorate of the Entente States, in order to guarantee port rights to Lithuania and Poland. In January 1923, the Klaipėda Revolt took place and Klaipėda region was annexed to Lithuania in 1923 under violation of the Treaty of Versailles. The subsequent incorporation of the territory brought economic prosperity to Lithuania, with the region accounting for 30% of the country's economy. However, the region's economic significance declined after economic sanctions were imposed by Nazi Germany in 1933.
