Georgia boycotted the March 17, 1991 all-Union referendum on the renewal of the Soviet Union proposed by Mikhail Gorbachev. However, the referendum was held in Abkhazia and 52.3% of the population of Abkhazia (virtually all the non-Georgians) took part, and participants voted by an overwhelming majority (98.6%) in favour of preserving the Union. Most of the non-Georgian population subsequently declined to participate in the March 31 referendum on Georgia's independence, which was supported by a huge majority of the population of Georgia. Shortly after it Georgia declared independence on 9 April 1991, under the rule of nationalist and former Soviet dissident Zviad Gamsakhurdia.
