Unrest began all around Bulgaria on 6 September and 7 September, with the strikes of the Pernik miners and the Sofia tram employees, as well as the general strikes in Plovdiv and Gabrovo. The prisons in Pleven, Varna and Sliven had their political prisoners released; 170 localities were entered by partisan detachments between 6 September and 8 September. In many cities and villages, the strikes and meetings grew into armed clashes with the police, with victims on both sides.
