The Treaty of Brest-Litovsk, signed in March 1918, had a significant impact on World War I as it marked Russia's exit from the conflict. Following the Bolshevik Revolution, the new Soviet government sought peace with Germany to focus on internal issues. The treaty ceded significant territories, including Poland, Ukraine, and the Baltic states, to Germany and its allies, allowing them to concentrate their forces on the Western Front. Although it provided temporary relief for Germany, the loss of Russian resources and manpower ultimately contributed to the Central Powers' defeat later in the war.
