The Treaty of Brest-Litovsk was linked with which policy?

Correct answer: Policy of leaving the war

The governing historical concept is the Bolshevik policy of ending Russia’s participation in the First World War. After the October Revolution, the new government sought peace because the war had exhausted soldiers, damaged the economy, and weakened the old regime. Russia signed the Treaty of Brest-Litovsk with Germany in March 1918 and accepted substantial territorial losses in order to withdraw from the conflict. Therefore, option A is correct. Option B is the opposite of the treaty’s immediate purpose. Option C is incorrect because the agreement was made by the revolutionary government and was not a plan to restore the Tsar. Option D is also wrong: a peace treaty ending Russia’s war participation cannot be described as inviting foreign rule.
