A significant number of provisionals is associated with the Civil War of 1918–1922. At that time, there was no stable central authority across most of the country; many regions became independent, and due to devastation and war there was considerable inflation. Frequent changes in postal rates and the inability to supply the postal network with stamps of the required denominations led to periodic revaluations of existing stocks in accordance with instructions from the People’s Commissariat of Posts and Telegraphs of the RSFSR, which did not provide for any overprints. However, locally, some post offices still applied overprints to the revalued stamps being sold, or simply wrote on them by hand. All these stamps are characterized by an extremely simple overprinting technique.
