Final answer:
Peace after March 1918 began with the Treaty of Brest-Litovsk between Germany and the Bolshevik-led Soviet Union and was followed by an armistice on November 11, 1918, after the collapse of the German front due to Allied forces, including U.S. troops.
Step-by-step explanation:
Peace After March 1918
After March 1918, peace came through a series of events that led up to the armistice in November. Initially, peace efforts were seen when President Wilson tried to promote the concept of "peace without victory," aiming to revert nations back to their pre-war territories.
Unfortunately, despite some agreement in the German Reichstag, European leaders did not accept this plan.
Peace was first officially obtained on the Eastern Front, where the Germans signed a generous peace treaty with the newly formed Soviet Union under the leadership of Lenin, following the Russian Revolution and the conclusion of the civil war in Russia. The treaty was known as the Treaty of Brest-Litovsk in March 1918.
Later in the year, U.S. troops boosted the Allied powers, leading to intense fighting that culminated in the German lines being broken by November.
Consequently, Kaiser Wilhelm II abdicated, and Germany reached out for an armistice which went into effect on November 11, 1918, at 11:00 a.m, marking a temporary end to hostilities. Formal peace negotiations followed, leading to the Treaty of Versailles in 1919.
