Similarities between the February and October revolution

The February 1917 revolution produced a democratic, republican government, with a, defacto, seperation of powers between the Duma (Russia's elected parliament created after the revolution of 1905) and the Soviets, workers councils also formed during 1905 and later, which until 1917 had no real political power.

The main aim of the Provisional government was to hold elections to Russia's first powerful parliament, the Constiuent Assembly.

Difference between the February and October revolution
The February Revolution toppled the old Tsarist government and instituted a temporary government run mostly by middle-class liberals who wanted to establish a constitutional republic. This government, however, failed to address the need for land reform and economic development, focusing its efforts instead on continuing the war. The October Revolution, on the other hand, was led by the Bolsheviks, radical Marxists who wished to establish a socialist republic of “soviets” (i.e. worker’s councils). This revolution permanently established communism in Russian politics; under communism, Russia would become one of the world’s major super powers, but millions of Russians would suffer under its repressions.
