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.
National Museum of Lithuania
The Museum of Antiquities in Vilnius, founded by Eustachy Tyszkiewicz in 1855, was the forerunner of today's museum. At its inception, the museum focused on the culture and history of the Lithuanian Grand Duchy. Made up mostly of Polish private collections, it was quite popular and received many visitors. After the January Uprising of 1863, the Russian Empire moved much of the collection to Moscow; the remaining collections were re-organized and were incorporated into the Vilnius Public Libray. From 1866 to 1914, the museum and the library operated together. In 1915, when the Eastern Front of World War I approached Vilnius, more of the exhibits was taken to Russia. 
After Lithuanian independence was established in 1918, the Museum of History and Ethnography was founded, based on the collections in the Museum of Antiquities and the Lithuanian Scientific Society. Its director was Jonas Basanavičius, one of the signatories to the Act of Independence of Lithuania. After 1919, Vilnius became a part of Poland, and the organization was incorporated into Vilnius University.
