On December 8, 1991, the presidents of Russia, Ukraine and Belarus signed the Belavezha Accords which declared the Soviet Union dissolved and established the Commonwealth of Independent States (CIS) in its place. While doubts remained over the authority of the Belavezha Accords to dissolve the Union, on December 21, 1991, the representatives of all Soviet republics except Georgia, including those republics that had signed the Belavezha Accords, signed the Alma-Ata Protocol, which confirmed the dismemberment and consequential extinction of the USSR and restated the establishment of the CIS. The summit of Alma-Ata also agreed on several other practical measures consequential to the extinction of the Union. On December 25, 1991, Gorbachev yielded to the inevitable and resigned as the president of the USSR, declaring the office extinct. He turned the powers that until then were vested in the presidency over to Boris Yeltsin, president of Russia.
