Subsequent steps toward full independence were taken on May 4, 1990. The Latvian SSR Supreme Council, elected in the first democratic elections since the 1930s, adopted a declaration restoring independence that included a transition period between autonomy within the Soviet Union and full independence. In January 1991, however, pro-communist political forces attempted to restore Soviet power with the use of force. Latvian demonstrators managed to stop the Soviet troops from re-occupying strategic positions (January 1991 events in Latvia). On August 21, after the unsuccessful attempt at a coup d'état in Moscow, parliament voted for an end to the transition period, thus restoring Latvia's pre-war independence. On September 6, 1991 Latvian independence was once again recognized by the Soviet Union.
