On 4 July, it passed the resolution to begin the uprising. Đilas was sent to Montenegro to organize and raise the struggle against the Italian occupying force, which on 12 July 1941 proclaimed the fascist puppet entity Kingdom of Montenegro, to be run by Sekula Drljević and closely controlled by the Italian authority of Alessandro Biroli, Mussolini's confidant. Đilas had an important role in the Uprising in Montenegro which was a national example, spanning ideological lines. Large parts of Montenegro were quickly liberated. Đilas remained in Montenegro until November.
