The Treaty of Versailles ended the war, but left many things unsettled-mostly because it placed all the blame on Germany for the war, and the Allies made them responsible for paying back all war debt. This immediately bankrupt Germany, and placed the Germans under immense economical distress and lowered the value of their currency to practically nothing. Germans were cast into poverty, and this set the stage for the rise of Hitler and the start of WWII. Hope I helped!! :)
