Lenin who had been allowed to return from exile, by the provisional government was now able to make one very big and important statement that he and his Bolshevik goverment would give the people an end to the war the one thing that the people wanted above all else because without the war they would have food and fuel. The people would now respect and welcome the Bolsheviks more after such a promise.
After the Lenin was allowed to return he could now create propaganda and recruit more people into the Bolsheviks, and say that he would do all the things that the provisional government had failed to do.
he said he would give the people peace (Which would come with an end to the war) Land (which would come when he got into power and could take the church's and the rich's land and divide it amongst the peasants) bread (which would come with an end to the war) and freedom (which he would create with an overthrow of the provisional government) this was still in the early stages of the provisional government and they still had time to change some things.
When the provisional government had come to power the peasants had expected to get a share of the land and an end to serfdom so that they could make money for themselves but the provisional government did not give them the land they wanted, intead they continued with the old systme because they did not want to anger the rich or the church. Lenin had promise to give the people land, now the people would lean even more towards his style of things.
Then the people wanted to have elections and elect their own ministers to represent them at government, the provisional government did respond to this in a way by creating Soviets these were councils of workers and peasants elected onto the council by peasants and workers, these Soviets were highly respected amongst the common people and would accept the things they said, so Lenin began to infiltrate these Soviets he would place Bolsheviks in them by only allowing the people to vote for a
Bolshevik and attacking any people who objected In Lenin's April Thesis where he had promised to give the people Peace, Land, Bread and Freedom he had also coined another slogan "All Power to the soviets"further increasing the respectability of the soviets, once inside his people could spread pro-bolshevik propaganda and the people would believe it further improving the opinion of the normal people about Bolsheviks.
Soon it was not only the Bolsheviks who saw the opputunity to take control of Russia General Kornilov was sick of the provisional government and decided that he would be better at running Russia and began to gather up the most hardened troops in Russia from the Ural mountians - The Savage Brigade these marched on Petrograd to attempt a miltitary coup. In an attempt to save the provisional government they armed the Bolshevik Red Guard to fight back the savage brigade, and they succeeded and beat back Kornilov, the Red Guard were then treat as heroes and repected now by the armies of Russia, now they had yet more respect from the normal people respect from the army, and guns.
Finally after months of planning and yet more propaganda producing and soviet infiltrating the Bolsheviks were ready to make their move, the Red Guard marched through Petrograd taking control of the power station and post offices, the guards at the massive Peter and Paul fortress that overlooked Petrograd and the only reallt threat to the Bolsheviks threw down their weapons and gave them to the Red Guards they then marched onto the Winter Palace and the seat of the provisional governement Bolsheviks sailors who had commendeered the Russian the warship the Aurora fired blank shells at the winter palace and the Red Guards stormed the gates they met very little resistance from the womens brigade and cadets that guarded the palace and took control of the seat of government.
The people were sick of the provisional government which had done nothing since it got into power and thought that the Bolsheviks would be a much better choice because they would give the people what they wanted the Bolsheviks were now in control of the seat of government further affirming their authority however there was a long road ahead before they would be in control of the rest of Russia.
They had seized power basically because they had promised to do what the provisional government would do and they had the guts to follow their revolution through to the end.
