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.
Lithuania
The first people settled in the territory of Lithuania after the last glacial period in the 10th millennium BC: Kunda, Neman and Narva cultures. 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. 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. Over a millennium, the Indo-Europeans, who arrived in the 3rd – 2nd millennium BC, mixed with the local population and formed various Baltic tribes.
The Baltic tribes did not maintain close cultural or political contacts with the Roman Empire, but they did maintain trade contacts (see Amber Road). Tacitus, in his study "Germania", described the Aesti people, inhabitants of the south-eastern Baltic Sea shores who were probably Balts, around the year 97 AD. The Western Balts differentiated and became known to outside chroniclers first. Ptolemy in the 2nd century AD knew of the Galindians and Yotvingians, and early medieval chroniclers mentioned Old Prussians, Curonians and Semigallians.
