On June 28, 1991, a few months before the dissolution of the Soviet Union, the autonomous oblast declared its sovereignty and separated from Krasnodar Krai. It was subsequently recognized as the Republic of Adygea within the Russian SFSR and retained its status of a republic within the Russian Federation after the formal dissolution of the Soviet Union in December 1991. Between 2004 and 2006, attempts were made to merge the republic with Krasnodar Krai, but the proposal met with strong resistance from the native Adyghe population and was eventually put to rest. The results of a 2011 opinion poll showed that 83% of the population of Adygea and over 90% of the population of Krasnodar Krai regard a potential merger in an unfavorable light.
