The Russian ruler associated with the phrase "Peace, Land, and Bread" is Vladimir Lenin. This slogan became a popular rallying cry during the October Revolution of 1917, reflecting the urgent demands of the Russian people for an end to the ongoing World War I, land redistribution to peasants, and basic necessities like food. Lenin and the Bolsheviks promised to deliver these essential reforms, galvanizing support among the war-weary populace and disillusioned soldiers. Ultimately, the phrase encapsulated the revolutionary vision of establishing a socialist state based on the principles of workers' and peasants' rights.
