20 points for detailed answer and brainliest, please only answer if you know it :( people keep answering this question with useless material. How did lenin rise to power? please go in depth on how and why :(

He led the October Revolution of 1917, in which the Communists seized power in Russia. He then ruled the country until his death in 1924. ... In short, Lenin called for the overthrow of the provisional government and its replacement with a communist form of government led by the working class. Lenin believed that a key policy of his government must be to withdraw from the ongoing First World War by establishing an armistice with the Central Powers of Germany and Austria-Hungary.

Does this help? :)
