Treaty of VersitilesIf I understand your question correctly you are asking what treaty formally ended the war (World War I) in 1918. There was NO treaty that ended the war in that year (1918). There, however, was an armistice (staring 11NOV1918) that ended the fighting on the Western Front, the only remaining front in the war (more about the Eastern Front in a minute) and so ended the war. The terms of surrender were to be worked out later and came to be known as the Treaty of Versialles which was the formal treaty that ended the war. This treaty was signed by the Germans on June 30, 1919 (not sure of date--might want to check that out). So, it was the Treaty of Versialles, which came into effect into 1919 that formally ended the war. The fighting on the Eastern Front (Russia) had ended in March of 1918 when Russia signed a separate peace treaty with Germany thus withdrawing from the war. But this didn't end all the fighting in World War I. The rest of the Allied powers continued fighting until 11NOV1918.
