He derived an increasingly large share of his power from his position as president through his resignation as General Secretary following the 1991 coup d'état attempt.
The idea of the institution of a sole head of state (instead of collegial leadership) first appeared during the preparation of the draft 1936 Soviet Constitution.
However, at the suggestion of the informal first person of the USSR, Joseph Stalin, who could compete with the official head of state, the idea was rejected.
Starting with Leonid Brezhnev in 1977, the last four general secretaries—Brezhnev, Yuri Andropov, Konstantin Chernenko, and Gorbachev—simultaneously served as de jure head of state during their time in office.
On 24 September 1990, Gorbachev persuaded the Supreme Soviet to give him the power to rule by unrestricted decree (on the economy, law and order, and the appointment of government personnel) until 31 March 1992.
During the election of the president several candidates were nominated, among leading contenders were KGB Chairman Vadim Bakatin and Premier Nikolai Ryzhkov.
