Question

Why October revolution in 1917 was considered a landmark in history of socialism

Answer 1

Vladimir Lanin was the leader of Bolsheviks. Bolsheviks were able to get support of the Soviets because they demanded for immediate and unconditional peace. They also demanded that all the land should be nationalised and redistributed to peasants. Bolsheviks wanted the control over prices and nationalisation of all factories and banks.
The Soviets under the Bolsheviks leadership seized power from the provincial government in October 1917.this was said to be called October revolution.
As here all the protest, demonstrations,demands was based on socialism and as this was the first attempt of human kind to adopt socialism, the October revolution was considered as a landmark in the history of socialism

Answer 2

Explanation:

The October Revolution in Russia in 1917 was the greatest event in modern history, the first stage of the world socialist revolution, the completion of which it is our task to carry out.

The working class and the rural poor in Russia, under the leadership of the Bolshevik Party of Lenin and Trotsky, rose up 100 years ago, took power and established their rule in the face of a ferocious counter-revolution and the intervention of all the great powers.

This past year, our international movement has marked the anniversary in a series of meetings, as well as extensive discussions of the events and personalities on our website, the World Socialist Web Site. No other political movement has paid one-tenth, perhaps one-hundredth the attention we have to the Russian Revolution, because we begin from the urgency of the present conditions, the massive crisis of capitalism, threatening poverty, dictatorship and war for the mass of the world’s population.
