'Explain How Marxism contributed to the Bolshevik Revolution'

There were other causes which led to the second Bolshevik revolution, Marxism was the final consequence of a rulers system riddled with faults. The Provisional Government in February 1917 promised elections which were to be held in December of the same year. To many starving Russians, 10 months isn't even a foreseeable future, let alone would they even have the care to think about the provisional government while they had to concentrate on surviving. What made things worse for the Provisional Government's reputation, was that they had continued with the war, one thing which would eventually cause so many soldiers to desert the army and join the Bolshevik party. The Provisional Government appeared to not have the worker's best interests at heart (from the eyes of the workers) and they only cared about the middle-class in the short term, them first the workers second, starving Russian proletariats found the Bolshevik party and Lenin's interpretation of Marxism extremely more appealing than the old Tsar or the current Government. Lenin interpreted  Karl Marx's theory as a complete and new found ideology of a way on how to control a country. Marx just made this a theory, Lenin wanted to put it into practice and was determined that this was to work. He promised 'Bread and Land' for everyone during his April Theses, his view on Marxism was to be spread throughout many Russian Workers, it was that class who were effected most by Marxism and Lenin, once the middle-class took over the country from the aristocracy and monarchy, Lenin had the idea to complete Marx's theory and the ideas of Marxism were very attractive now to the workers. This also affected the soldiers fighting in central Europe for the Russians, those who deserted were classed as traitors committing treason by the Provisional Government, Lenin's views on Marxism were attractive for the soldiers who could join the Bolsheviks on the promise of land and bread, much rather than being tried and killed for desertion by the government. In the front on which the Russians fought, Bolshevism came to them in the way of pamphlets, the ideas expressed by Lenin were a glimmer of hope for the soldiers, who were fighting a war in which they had been conscripted for and a far majority probably had no idea why the war had started. Lenin's ideology promised then the peace which many so badly craved, and Lenin promised so much more than the Provisional Government could offer them.  Marxism contributed greatly towards the second Bolshevik revolution, but it was not the one and only cause. The failures by the Tsar and the Provisional government left the way open for the Bolsheviks to take control of a country much I need of a party for the workers.
