There are many factors that contributed to the second revolution and the Bolsheviks success in seizing power in 1917, but these were not all attributable to the strengths of the party leader, Lenin, alone. Although within the party, he made a great impact on their tactics and decisions, there were other, perhaps more significant factors which led to the second revolution. The weakness of the Provisional Government was also an enabling factor, and overall it could be argued that although Lenin played a key role and without him the party may not have seized power, the weakness of the provisional government also played a crucial role, as without this they would not have seized power.
The Provisional Government lacked real power to make long term decisions for Russia, as it was a temporary body. The Provisional Government felt that they should not make binding decisions affecting Russia in the long term with issues such as the land distribution for peasants, as this would be for the Constituent Assembly to decide.
