Why did lenin sign the treaty of brest litovsk?

Lenin signed the Treaty of Brest-Litovsk in March 1918 primarily to secure peace for Russia after the tumultuous years of World War I and the Russian Revolution. The treaty allowed the Bolshevik government to focus on consolidating power and addressing internal issues rather than continuing a costly war against Germany. Although it resulted in significant territorial losses for Russia, Lenin believed that a swift exit from the war was essential for the survival of the revolution and the establishment of a socialist state.
