The long-awaited
Constituent Assembly elections were held on 12 November (O.S., 25 November, N.S.) 1917. In contrast to their majority in the Soviets, the Bolsheviks only won 175 seats in the 715-seat legislative body, coming in second behind the
Socialist Revolutionary Party, which won 370 seats, although the SR Party no longer existed as a whole party by that time, as the Left SRs had gone into coalition with the Bolsheviks from October 1917 to March 1918 (a cause of dispute of the legitimacy of the returned seating of the Constituent Assembly, as the old lists, were drawn up by the old SR Party leadership, and thus represented mostly Right SRs, whereas the peasant soviet deputies had returned majorities for the pro-Bolshevik Left SRs). The Constituent Assembly was to first meet on 28 November (O.S.) 1917, but its convocation was delayed until 5 January (O.S.; 18 January, N.S.) 1918 by the Bolsheviks. On its first and only day in session, the Constituent Assembly came into conflict with the Soviets, and it rejected Soviet decrees on peace and land, resulting in the Constituent Assembly being dissolved the next day by order of the Congress of Soviets.
