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 first humans arrived on the territory of modern Lithuania in the 10th millennium BC after the glaciers receded at the end of the last glacial period. According to the historian Marija Gimbutas, these people came from two directions: the Jutland Peninsula and from present-day Poland. They brought two different cultures, as evidenced by the tools they used. They were traveling hunters and did not form stable settlements. In the 8th millennium BC, the climate became much warmer, and forests developed. The inhabitants of what is now Lithuania then traveled less and engaged in local hunting, gathering and fresh-water fishing. During the 6th–5th millennium BC, various animals were domesticated and dwellings became more sophisticated in order to shelter larger families. Agriculture did not emerge until the 3rd millennium BC due to a harsh climate and terrain and a lack of suitable tools to cultivate the land. Crafts and trade also started to form at this time. 
Speakers of North-Western Indo-European might have arrived with the Corded Ware culture around 3200/3100 BC.
