How did Lenin stop Russians involvement in the World War 1?

Lenin sought to end Russia's involvement in World War I through the Treaty of Brest-Litovsk, signed in March 1918. After the Bolshevik Revolution in October 1917, Lenin prioritized peace to stabilize the new regime and redirect focus to internal issues. The treaty resulted in significant territorial losses for Russia but allowed the Bolsheviks to consolidate power and withdraw from the war, fulfilling their promise of peace to the war-weary populace.
