Lithuania (at that time - The Grand Duchy of Lithuania) made a Treaty with Poland in 1569. The country was taken over by the Russian Empire in 1795, ending the Polish-Lithuanian Commonwealth. It got back its independence on February 16, 1918. It was taken over by the Soviet Union on June 16, 1940, by Nazi Germany from 1941-1944 and again the Soviet Union from 1944-1990. Lithuania re-declared its independence on March 11, 1990. Currently, Lithuania is an independent, semi-presidential, democratic republic.
