Why were Germans angry at the end of World War 1?
At the Treaty of Versailles, the Germnas were truly insulted. They didn't have their own voice and the Treaty was unfair. It shifted all the blame of starting WWI to Germany, where in fact other countries also supported in creating the war. The Germans were also angry because they had to pay all the reparations and they had their economy drained out. These reasons held the German superioty back from other countries and it wanted revenge. That is the reason why Germany was angry at the end of WWI.
