<span>Czar Nicholas II was executed by
Bolshevik forces in July of 1918. The Bolsheviks were committed to the
ideas of Karl Marx, and they believed that the working classes would

provisional government was never elected, and it chose to remain in
World War I, despite the fact that the country was ill-equipped to fight
against Germany. This made people more in favor of the revolution.
