The Soviet Union was the chief
communist country in the world from 1917 until its dissolution in late-1991. At its formation, it was a conglomeration of several countries such as Russia (Russian Soviet Federative Socialist Republic), Georgia, Armenia, and Azerbaijan (Transcaucasian Socialist Federative Soviet Republic), Ukraine (Ukrainian Soviet Socialist Republic) and Belarus (Byelorussian Soviet Socialist Republic).
Later, expansion took direct control of several other countries and they were folded into Soviet Union. Lithuania, Latvia, Estonia, and what is now Moldova.
Following World War 2, the influence of the Soviet Union was felt throughout
Eastern Europe. All the countries living behind what was later called the
Iron Curtain essentially became puppet states or colonies.
