In July 1990, the Belarusian Popular Front initiated the passing of the Declaration of State Sovereignty of the Belarusian Soviet Socialist Republic. In August 1991, following the 1991 Soviet coup d'état attempt and supported by tens of thousands of protesters outside the parliament building, the Belarusian Popular Front has managed to convince the Supreme Soviet to declare full independence of Belarus from the USSR. The historical Belarusian national symbols: the white-red-white flag and the "Pahonia" coat of arms were restored as state symbols of Belarus.
