Germany was forced to take most of the blame for WWI. This meant huge loss in military forces, territories, and economy. The treaty required Germany to pay a huge amount of money for reparations. The problem with the treaty is that it left German economy in chaos. People were starving and the government was in ruins.
This unfortunately even set the stage for WWII because Hitler promised all the Germans that he would improve the country if he was voted to be the ruler.
