Who had the most to gain from a revolution in the Russian government?

The Bolsheviks, led by Vladimir Lenin, had the most to gain from a revolution in the Russian government. They aimed to overthrow the existing Tsarist regime and establish a socialist state, thereby addressing the grievances of the working class and peasantry. Their revolutionary ideology appealed to those suffering from economic hardship and political oppression, allowing them to mobilize support effectively. Ultimately, the revolution enabled the Bolsheviks to seize power and implement their vision for Russia's future.
