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.
Lithuania–Russia relations
In 1795, Vilna Governorate (consisting of eleven s or districts) and Slonim Governorate, were established by the Russian Empire after the third partition of the Polish-Lithuanian Commonwealth. Just a year later, on December 12, 1796, by order of Tsar Paul I they were merged into one governorate, called the Lithuanian Governorate, with its capital in Vilnius. By order of Tsar Alexander I on September 9, 1801, the Lithuanian Governorate was split into the Lithuania-Vilnius Governorate and the Lithuania-Grodno Governorate. After 39 years, the word "Lithuania" was dropped from the two names by Nicholas I. In 1843, another administrative reform took place, creating the Kaunas Governorate (Kovno in Russian) out of seven western districts of the Vilnius Governorate, including all of Žemaitija. The Vilnius Governorate received three additional districts: Vileyka and Dzisna from the Minsk Governorate and Lida from Grodno Governorate. It was divided to districts of Vilnius, Trakai, Disna, Oshmyany, Lida, Vileyka and Sventiany. This arrangement remained unchanged until World War I. A part of the Vilnius Governorate was then included in the Lithuania District of Ober-Ost, formed by the occupying German Empire.
