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 (1219–95)
The first ruler to hold the title of Grand Duke was Mindaugas. Traditionally he is considered the founder of the state, the one who united the Baltic tribes and established the Duchy. Some scholars, however, challenge this perception, arguing that an organized state existed before Mindaugas, possibly as early as 1183. After quelling an internal war with his nephews, Mindaugas was baptized in 1251, and was crowned as King of Lithuania in 1253. In 1261, he broke the peace with the Livonian Order, perhaps even renouncing Christianity. His assassination in 1263 by Treniota ended the early Christian kingdom in Lithuania. For another 120 years Lithuania would remain a pagan empire, fighting against the Teutonic and Livonian Orders during the Northern Crusades during their attempts to Christianize the land.
