The 1980 Summer Olympics, officially known as the Games of the XXII Olympiad (Russian: И́гры XXII Олимпиа́ды, tr. Igry XXII Olimpiady), was an international multi-sport event held in Moscow, Soviet Union, in present-day Russia. The 1980 Games were the first Olympic Games to be staged in Eastern Europe, and remain the only Summer Olympics held there, as well as the first Olympic Games to be held in a Slavic language-speaking country. They were also the only Olympic Games to be held in a communist country until 2008 in China. These were the final Olympic Games under the IOC Presidency of Michael Morris, 3rd Baron Killanin. Eighty nations were represented at the Moscow Games – the smallest number since 1956. Led by the United States, 66 countries boycotted the games entirely because of the Soviet–Afghan War. Some athletes from some of the boycotting countries (they are not included in the list of 66 countries that boycotted the games entirely) participated in the games under the Olympic Flag. The Soviet Union would later boycott the 1984 Summer Olympics. The Soviet Union won the most gold and overall medals, with the USSR and East Germany winning 127 out of 204 available golds.
