Final answer:
Fascism and totalitarianism impacted international affairs between World War 1 and World War 2 by leading to aggressive foreign policies, territorial expansion, and the mistreatment of minority groups.
Step-by-step explanation:
Fascism and totalitarianism had a significant impact on international affairs between World War 1 and World War 2. Both ideologies aimed to establish control over all aspects of a person's life and promote the nation's interests above all else. In Italy, Benito Mussolini rose to power and established a fascist dictatorship, while in Germany, Adolf Hitler's Nazi regime sought expansion and dominance.
The rise of fascism and totalitarianism led to aggressive foreign policies and territorial ambitions. Germany, under Hitler, invaded neighboring countries and sought to establish a dominant position in Europe. Italy, too, pursued territorial expansion and fought alongside Germany in World War II. These aggressive actions and territorial acquisitions heightened tensions between nations, leading to the outbreak of World War II.
Additionally, the ideologies of fascism and totalitarianism promoted exclusionary and supremacist beliefs, leading to the persecution and mistreatment of minority groups and exacerbating international tensions. Anti-Semitic policies in Nazi Germany, for example, led to the Holocaust and widespread human rights abuses.
