1. What was the significance to arming the Petrograd soviet?

In the context of the general national crisis that seized Russia in the autumn of 1917, the shift of the Petrograd Soviet of Workers' and Soldiers' Deputies to the side of the Bolshevik Party became an important indication of the revolutionary upsurge and the masses' readiness to support the Bolsheviks in their struggle to overthrow the Provisional Government and transfer all power to the proletariat and the poorest peasantry. The Bolsheviks' victory in the Soviets of both capitals was one of the main factors inducing Lenin to pose the question of organizing an armed uprising to the party. "Now that they have gotten the support of a majority in the Soviets of Workers' and Soldiers' Deputies of both capitals, the Bolsheviks can and must take governmental power into their own hands,"1 he wrote in September of 1917.
