President of the Soviet Union after the 1991 coup d'état attempt. The presidency was an executive post, based on a mixture of the U.S. and French presidencies. Prior to the creation of the post of president, the "de jure" head of state of the Soviet Union was the chairman of the Presidium of the Supreme Soviet, who was often called the "president" by non-Soviet sources. For most of the Soviet Union's existence, all effective executive political power was in the hands of the General Secretary of the Communist Party of the Soviet Union, with the Chairman of the Presidium exercising largely symbolic and figurehead duties.
