Heydar Aliyev, the future president of Azerbaijan, returned to his birthplace of Nakhchivan in 1990, after being ousted from his position in the Politburo by Mikhail Gorbachev in 1987. Soon after returning to Nakhchivan, Aliyev was elected to the Supreme Soviet by an overwhelming majority. Aliyev subsequently resigned from the CPSU and after the failed August 1991 coup against Gorbachev, he called for complete independence for Azerbaijan and denounced Ayaz Mütallibov for supporting the coup. In late 1991, Aliyev consolidated his power base as chairman of the Nakhchivan Supreme Soviet and asserted Nakhchivan's near-total independence from Baku.
