The March revolution or The Russian Revolution of 1917. The Russian Revolution of 1917 involved the collapse of an empire under Tsar Nicholas II and the rise of Marxian socialism under Lenin and his Bolsheviks. It sparked the beginning of a new era in Russia that had effects on countries around the world. I hope that helps!
By the end of WWII, the balance of power had shifted away from Europe. The United States and the Soviet Union became world powers.The U.S. and Filipino people surrendered to Japan in 1942.
