1918 Russian Constitution

The first constitution of Russia, which governed the Russian Socialist Federative Soviet Republic, described the regime that assumed power in the October Revolution of 1917. This constitution, which was ratified soon after the Declaration Of Rights Of The Working And Exploited People, formally recognized the working class as the ruling class of Russia according to the principle of the dictatorship of the proletariat, therein making the Russian SFSR the world's first constitutionally socialist state.

The ultimate aims of the state were outlined as: "the abolition of the exploitation of men by men, the entire abolition of the division of the people into classes, the suppression of exploiters, [and] the establishment of a socialist society." The constitution stated that an historical alliance had been formed between the workers and peasants, who together would govern the state through the soviets. The constitution explicitly denied political power to higher classes of Russian society or to those who supported the White armies in the Civil War (1918–21). To prevent the higher classes from re-claiming state power, the first article called for all workers and peasants to be armed and organized into a Red Army while the higher classes be fully disarmed.

Supreme power rested with the All-Russian Congress of Soviets, made up of deputies from local soviets across Russia. The steering committee of the Congress of Soviets—known as the Central Executive Committee—acted as the "supreme organ of power" between sessions of the congress and as the collective presidency of the state.

The congress elected the Council of People's Commissars (Sovnarkom, Sovet narodnykh kommissarov) as the administrative arm of the young government and defined its responsibilities as "general administration of the affairs of the state". (The Sovnarkom had exercised governmental authority from November 1917 until the adoption of the 1918 constitution July 10 by the Congress of Soviets.)
