Reasons For the Bolsheviks' Seizure of Power
How was the October Revolution Different to Other Revolutions in Russia? - Timeline & Summary

The October Revolution was very different to the revolutions in 1905 and March 1917. In 1928, the Bolsheviks commissioned Sergei Eisenstein to create a film about the October Revolution. The film, October, shows masses of people storming the gates of the Winter Palace under heavy gunfire. In reality, the gates of the Winter Palace were unguarded and open. The Bolsheviks faced little resistance from the remaining members of the Provisional Government. Historians consider the events of October 1917 a coup. As a result, the only popular revolution in Russia was in March 1917. This is because the events of 1905 did not result in the overthrow of the tsar.
Many Russians considered the October Revolution as a temporary change of government. Tsereteli, the leader of the Mensheviks, stated that the Bolsheviks' power would not last three weeks. At this point, the Bolsheviks were a small, extremist party. The Bolsheviks would end up establishing a dictatorship that remained in power for over 70 years.
