After the war ended, Germany was blamed, despite the fact that it was Austro-Hungary that started the War. The treaty prevented the German government from having an airforce or navy, and severely limited the German Army. Because of this humiliation, this would be used as a pretext for Adolf Hitler.
One of the most controversial terms of the treaty was the War Guilt Clause, which explicitly and directly blamed Germany for the outbreak of hostilities. The treaty forced Germany to disarm, make concessions over territory, and pay reparations to the Allied powers in the staggering amount of $5 billion.
