The Treaty of Versailles, which was signed at the end of World War I, placed heavy economic and territorial burdens on Germany. The treaty required Germany to pay a large amount of reparations to the victors of the war, which placed a significant economic strain on the country. Additionally, Germany was forced to give up territories that had historically been part of its territory, including the Rhineland and Alsace-Lorraine.
These harsh terms of the treaty led to a sense of resentment and anger among many Germans, who felt that they had been unfairly punished for a war that they did not start. This resentment was exploited by the Nazi party, which rose to power in Germany during the 1930s. The Nazis promised to restore Germany's former glory and to reclaim the territories that had been taken away from them.
As a result, Germany began to aggressively expand its territory through the invasion of neighboring countries, including Austria and Czechoslovakia. When Germany invaded Poland in 1939, this led to the start of World War II.
Therefore, it can be argued that the harsh terms of the Treaty of Versailles played a significant role in the outbreak of World War II, by creating the conditions that allowed for the rise of Nazi Germany and its aggressive expansionist policies.
