What change came in Russia's war policy through the Treaty of Brest Litovsk?

Correct answer: Russia withdrew from the First World War

Direct answer: Option C, Russia withdrew from the First World War. The Treaty of Brest-Litovsk was signed in 1918 between the Bolshevik government of Russia and the Central Powers. The Bolsheviks had promised peace, and leaving the war was important because soldiers, workers, and the economy were exhausted. Step by step: the revolution changed the government; the new government wanted peace; it negotiated a separate treaty; Russia accepted difficult territorial terms; in return, it stopped fighting in the First World War. C is correct. A is wrong because the treaty ended Russia’s participation rather than expanding the war. B is wrong because it concerned war withdrawal, not restoration of the Tsar. D is wrong because it did not establish Church rule. Memory cue: Brest-Litovsk = Bolshevik peace policy put into action and Russia out of World War I.
