According to Marxist theory, what was a primary factor that led to the success of the Russian Revolution in 1917?

According to Marxist theory, a primary factor that led to the success of the Russian Revolution in 1917 was the intense class conflict between the working class, known as the proletariat, and the ruling class, known as the bourgeoisie. The workers were suffering from poor living conditions, low wages, and a lack of rights, while the wealthy elite enjoyed great power and wealth. This deep divide created a strong desire for change among the workers, who were inspired to rise up against their oppressors. For example, in cities like Petrograd, workers organized strikes and protests, demanding better conditions and an end to the war. Ultimately, this class struggle fueled the revolution, allowing the Bolsheviks to seize power and establish a new government focused on the needs of the working class.
