In July 1991, Bush and Gorbachev signed the Strategic Arms Reduction Treaty (START I) treaty, the first major arms agreement since the 1987 Intermediate Ranged Nuclear Forces Treaty. Both countries agreed to cut their strategic nuclear weapons by 30 percent, and the Soviet Union promised to reduce its intercontinental ballistic missile force by 50 percent. In August 1991, hard-line Communists launched a coup against Gorbachev; while the coup quickly fell apart, it broke the remaining power of Gorbachev and the central Soviet government. Later that month, Gorbachev resigned as general secretary of the Communist party, and Russian president Boris Yeltsin ordered the seizure of Soviet property. Gorbachev clung to power as the President of the Soviet Union until December 1991, when the Soviet Union dissolved. Fifteen states emerged from the Soviet Union, and of those states, Russia was the largest and most populous. Bush and Yeltsin met in February 1992, declaring a new era of "friendship and partnership". In January 1993, Bush and Yeltsin agreed to START II, which provided for further nuclear arms reductions on top of the original START treaty.
