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.
Administrative divisions of Lithuania
Under the Russian Empire, the territory of the former Grand Duchy of Lithuania was divided into governorates (Russian: "guberniya", Lithuanian: "gubernija") and districts (Russian: "uyezd", Lithuanian: "apskritis"). Such system was introducing in Russia during the reforms of 1775. The first governorates, Vilna Governorate (consisting of eleven districts) and Slonim Governorate, were established after the third partition of the Polish–Lithuanian Commonwealth. Just a year later, on December 12, 1796, they were merged into one governorate, called Lithuania Governorate, with capital in Vilnius. In 1801 Lithuania Governorate was split into Lithuania-Vilna Governorate and Lithuania-Grodno Governorate. Forty years later the word "Lithuania" was dropped from the two names and official maps of Europe. The territory of the former Grand Duchy of Lithuania became known as the Northwestern Krai. In 1843 another administrative reform took place, creating Kovno Governorate out of seven western districts of the Vilna Governorate. Vilna Governorate received three additional districts: Vileyka and Dzisna from Minsk Governorate and Lida from Grodno Governorate.
