The officers of the army of the fallen Tsar organised an armed rebellion against the Soviet state. Troops of foreign powers—England, France, Japan, the United States and others— joined them. War was fought till 1920. By this time the ‘Red Army’ of the new state was in control of almost all the lands of the old Czarist empire. Indeed, a revolutionary wave lasted until 1923.
