Politically the USSR was divided (from 1940 to 1991) into 15 constituent or union republics—Armenia, Azerbaijan, Belorussia (see Belarus), Estonia, Georgia, Kazakhstan, Kirghizia (see Kyrgyzstan), Latvia, Lithuania, Moldavia (see Moldova), Russia, Tadzhikistan (see Tajikistan), Turkmenistan, Ukraine, and Uzbekistan—ostensibly joined in a federal union, but until the final year or so of the USSR's existence the republics had little real power. Russia, officially the Russian Soviet Federal Socialist Republic (RSFSR), was only one of the constituent republics, but the terms "Russia," the "USSR," and the "Soviet Union" were often used interchangeably.
