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
On July 17, 1251, Pope Innocent IV signed two papal bulls that ordered the Bishop of Chełmno to crown Mindaugas as King of Lithuania, appoint a bishop for Lithuania, and build a cathedral. In 1253, Mindaugas was crowned and a Kingdom of Lithuania was established for the first and only time in Lithuanian history. Mindaugas "granted" parts of Yotvingia and Samogitia that he did not control to the Knights in 1253–1259. A peace with Daniel of Galicia in 1254 was cemented by a marriage deal involving Mindaugas' daughter and Daniel's son Shvarn. Mindaugas' nephew Tautvilas returned to his Duchy of Polotsk and Samogitia separated, soon to be ruled by another nephew, Treniota.
