Difference between October revolution and September …

February Revolution:

•  22nd February: Factory lockout on the right bank took place.
•  25th February: Duma was dissolved.
•  27th February: Police Headquarters ransacked. Regiments support the workers. Formation of Soviet.
•  2nd March: The Tsar abdicated his power. The Soviet and Duma leaders formed a Provisional Government for Russia.

The February Revolution had no political party at its forefront. It was led by the people themselves. Petrograd had brought down the monarchy, and thus, gained a significant place in Soviet history. Trade Unions grew in number. With no monarchy to rule the Russian future would now be decided by the constituent assembly which was going to be elected on the basis of universal adult suffrage.

October Revolution:

•  16th October: A Military Revolutionary Committee was appointed by Soviet.
•  24th October: The uprising against the provisional government begins. Military Revolutionary Committee controls the city by night and ministers surrender. The Bolshevik gained power.

The October Revolution was primarily led by Lenin and his subordinate, Trotskii and involved the masses who supported these leaders. It marked the beginning of Lenin's rule over the Soviet, with the Bolsheviks under his guidance. The Bolshevik party after the revolution came to be known as the Russian Communist Party.

Russian Revolution, also called Russian Revolution of 1917, two revolutions in 1917, the first of which, in February (March, New Style), overthrew the imperial government and the second of which, in October (November), placed the Bolsheviks in power. On November 6 and 7, 1917 (or October 24 and 25 on the Julian calendar, which is why the event is often referred to as the October Revolution), leftist revolutionaries led by Bolshevik Party leader Vladimir Lenin launched a nearly bloodless coup d'état against the Duma's provisional government. October Revolution, also called Bolshevik Revolution, (Oct. 24–25 [Nov. 6–7, New Style], 1917), the second and last major phase of the Russian Revolution of 1917, in which the Bolshevik Party seized power in Russia, inaugurating the Soviet regime.
