History of Lithuania
On February 16, 1918, Lithuania was re-established as a democratic state. It remained independent until the outset of World War II, when it was occupied by the Soviet Union under the terms of the Molotov–Ribbentrop Pact. Following a brief occupation by Nazi Germany after the Nazis waged war on the Soviet Union, Lithuania was again absorbed into the Soviet Union for nearly 50 years. In 1990–1991, Lithuania restored its sovereignty with the Act of the Re-Establishment of the State of Lithuania. Lithuania joined the NATO alliance in 2004 and the European Union as part of its enlargement in 2004.
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.
