World War I weakened Russia as Nicholas II insisted on involvement despite unpreparedness. Alexandra allowed Rasputin, a religious figure, influence over government which further deteriorated conditions. In 1917, widespread strikes and riots erupted over food shortages and the war, forcing Nicholas to abdicate and ending three centuries of Romanov rule. A provisional government took over but struggled as Bolsheviks gained power appealing for "Peace, Land, and Bread." In November 1917 the Bolsheviks stormed the government, establishing their rule over Russia.
