After the March 1991 referendum confirmed the preservation of the Soviet Union but in a looser form, a group of Soviet hard-liners represented by Vice-President Gennadi Yanayev launched a coup attempting to overthrow Gorbachev in August 1991. Boris Yeltsin, then president of the Russian SFSR, rallied the people and much of the army against the coup and the effort collapsed. Although restored to power, Gorbachev's authority had been irreparably undermined. Gorbachev resigned as General Secretary of the Communist Party following the coup, and the Supreme Soviet dissolved the Party and banned all Communist activity on Soviet soil. Just a few weeks later, the government granted the Baltic states their independence on 6 September.
