World War I and the Treaty of Versailles contributed to the rise of Adolf Hitler and the Nazi Party in Germany by creating an atmosphere of national shame, economic hardship, and resentment that Hitler and the Nazi Party were able to exploit for their own political gain. Hitler used the perceived injustices of the treaty and the perceived failures of the government to gain support for his own ideology, which promised to restore the power and glory of Germany. The Nazi Party eventually gained control of the government in 1933 and played a key role in the outbreak of World War II.
