Russian Constituent Assembly
Soviet membership was initially freely elected, but many members of the Socialist Revolutionary Party, anarchists, and other leftists created opposition to the Bolsheviks through the Soviets themselves. The elections to the Russian Constituent Assembly took place 25 November 1917. The Bolsheviks gained 25% of the vote. When it became clear that the Bolsheviks had little support outside of the industrialized areas of Saint Petersburg and Moscow, they simply barred non-Bolsheviks from membership in the Soviets. The Bolsheviks dissolved the Constituent Assembly in January 1918.
