Uzbek Soviet Socialist Republic different from УССР (USSR)
Independence
The Uzbek SSR participated in the referendum in March 1991 as a part of the proposed Union of Soviet Sovereign States. This never came to pass after unsuccessful coup attempt events between 19 and 21 August 1991 in Moscow. In the aftermath, the Uzbek SSR was renamed the Republic of Uzbekistan and declared its independence on 31 August 1991, with the Soviet Union dissolving on 26 December 1991. After independence, the 1978 Constitution remained in use. The referendum was confirmed on 29 December 1991.
