Which country does this flag belong to?

Explanation

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 from 1918 to 1940, which ceased with the occupation first by Soviet Russia and Lithuania''s annexation into the Soviet Union, and then by 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 bands at the bottom.
