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.
Flag of Lithuania
The flag of Lithuania () consists of a horizontal tricolor of yellow, green, and red. It was adopted on 25 April 1918 during Lithuania's first period of independence (in the 20th century) from 1918 to 1940, which ceased with the occupation first by Soviet Russia and Lithuania's annexation into the Soviet Union, and then by Nazi Germany (1941–1944). During the post-World War II Soviet occupation, from 1945 until 1989, the Soviet Lithuanian flag consisted first of a generic red Soviet flag with the name of the republic, then changed to the red flag with white and green bars at the bottom.
