This small and ancient Baltic state had enjoyed but two decades of independence since the 13th century until the present time. After having been conquered by the Danes, the Livonian knights, the Teutonic Knights of Germany, the Swedes, the Poles and Russia, Estonia declared itself an independent republic on February 24, 1918 but was not freed until February 1919. The peace treaty was signed February 2, 1920. Shortly after the start of World War II, it was occupied by Russia and incorporated as the 16th state of the USSR. Germany occupied the tiny state from 1941 to 1944, after which it was retaken by Russia. Most of the nations of the world did not recognize Estonia's incorporation into the Soviet Union.
The coinage, issued during the county's brief independence, is obsolete.
On August 20, 1991, the Parliament of the Estonian Soviet Socialist Republic voted to reassert the republic's independence.
