The name of the "Mir" space station – , literally "Peace" or "World" – was to signify the intentions of the Soviet Union to bring peace to the world. However, it was during the time of "Mir" that the Soviet Union was dissolved in December 1991, ending what was begun with the 1917 October Revolution in Russia. This dissolution had started with the Soviet "perestroika and glasnost" ("restructuring and openness") reform campaigns by Soviet leader Mikhail Gorbachev in the 1980s, had reached a preliminary endpoint with the revolutions of 1989 and the end of the communist Eastern Bloc (Warsaw Pact and the Comecon), finally to reach the Soviet Union itself in 1991.
