Outline of Lithuania
During the 14th century, Lithuania was the largest country in Europe, as present-day Belarus, Ukraine, and parts of Poland and Russia were territories of the Grand Duchy of Lithuania. With the Lublin Union of 1569 Poland and Lithuania formed a new state: the Polish–Lithuanian Commonwealth, which was finally destroyed by its neighboring countries in 1795. Most of Lithuania's territory was annexed by the Russian Empire, until the Act of Independence was signed on 16 February 1918, which declared re-establishment of a sovereign state. Between 1940 and 1945 Lithuania was occupied by both the Soviet Union and Nazi Germany at different times. When World War II was near its end in 1944 and the Nazis retreated, the Soviet Union reoccupied Lithuania. On 11 March 1990, Lithuania became the first Baltic republic to declare its restored independence after 50 years of Soviet occupation.
Lithuania became a full member of the Schengen Agreement on 21 December 2007. In 2009, Lithuania celebrated the millennium of its name.Geography of Lithuania
History of Lithuania
The warfare with the Teutonic Order continued from 1345, and in 1348, the Knights defeated the Lithuanians at the Battle of Strėva. Kęstutis requested King Casimir of Poland to mediate with the pope in hopes of converting Lithuania to Christianity, but the result was negative, and Poland took from Lithuania in 1349 the Halych area and some Ruthenian lands further north. Lithuania's situation improved from 1350, when Algirdas formed an alliance with the Principality of Tver. Halych was ceded by Lithuania, which brought peace with Poland in 1352. Secured by those alliances, Algirdas and Kęstutis embarked on the implementation of policies to expand Lithuania's territories further.
