What were some of the important provisions of the treaty of versailles?

The treaty forced Germany to concede a lot of its territory. Some examples include the return of Alsace-Lorraine and the Saar to France, the return of the Hultschin district to Czechoslovakia and Eupen-Malmedy to Belgium

The treaty was negotiated  in Paris and was written by the Allies with almost no participation by the Germans. The French wanted to dismember Germany to make it impossible to renew war with France. The treaty included fifteen parts and 440 articles. It created the New League of Nations, which Germany was not allowed to join. Part II gave Germany’s new boundaries, and gave Eupen-Malm to Belgium, Alsace-Lorraine back to France, eastern districts to Poland, Memel to Lithuania, and portions of Schleswig to Denmark. Part III stipulated a demilitarized zone. Part IV stripped Germany of all its colonies, and Part V reduced Germany’s armed forces and prohibited Germany from possessing certain weapons. Germany also had to make reparations and accept the responsibility of itself and its allies for the losses and damages “as a consequence of the war imposed upon them by the aggression of Germany and her allies.” Part IX imposed  other financial obligations upon Germany.
