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
By that time, for the sake of its long-term survival, the Grand Duchy of Lithuania had initiated the processes leading to its imminent acceptance of European Christendom. The Teutonic Knights aimed at a territorial unification of their Prussian and Livonian branches by conquering Samogitia and all of Lithuania proper, following the earlier subordination of the Prussian and Latvian tribes. To dominate the neighboring Baltic and Slavic people and expand into a great Baltic power, the Knights used German and other volunteer fighters. They unleashed 96 onslaughts in Lithuania during the period 1345–1382, against which the Lithuanians were able to respond with only 42 retributive raids of their own. Lithuania's Ruthenian empire in the east was also threatened by both the unification of Rus' ambitions of Moscow and the centrifugal activities pursued by the rulers of some of the more distant provinces.
