The treaty required Germany to give up a large amount of territory, including Alsace-Lorraine, which had been part of Germany since 1871. Germany also had to pay reparations to the Allied Powers, which totaled 132 billion gold marks. This was a huge sum of money, and it caused great economic hardship in Germany.
The treaty also limited the size of the German military, and it forbade Germany from having an air force or submarines. This made many Germans feel that their country was defenseless, and it contributed to the rise of nationalist sentiment in Germany.
In addition, the treaty placed the blame for World War I on Germany. This was a very controversial provision, and it angered many Germans. They felt that they had been unfairly blamed for the war, and they resented the fact that they were being punished for it.
The Treaty of Versailles was a major factor in the rise of the Nazi Party. It created a sense of resentment and anger among many Germans, and it helped to create the conditions that allowed Hitler to come to power.
