 In 1922, during the civil war, the Soviet government tried to enforce Communist economic ideals and eliminate debt through systematic devaluation of the ruble and its associated currencies (various forms of Imperial ruble, kerenki and later sovznaki).Meanwhile, the authorities introduced a parallel currency, called the chervonets, which was fully convertible and backed by the gold standard.The chervonets existed in paper form (for domestic circulation) and as gold coins (for international payments).
