There are several reasons why so many dictators were able to rise to power during the years before World War 2:
1. Economic instability: The period between World War 1 and World War 2 was marked by economic instability all over the world, with many countries struggling with poverty, unemployment, and inflation. This provided an environment in which people were more willing to accept radical change, including the rise of dictators who promised solutions to these economic problems.
2. Nationalism: Many countries were grappling with the aftermath of World War 1, which had resulted in the loss of territory and national prestige for many nations. This led to a rise in nationalism, which fueled the rise of authoritarian leaders who promised to restore their country's former glory.
3. Weakness of democratic institutions: In many countries, democratic institutions were weak and unable to cope with the challenges of the time. This led to a breakdown of trust in democratic systems, which in turn made it easier for dictators to rise to power.
4. Propaganda: Many of the dictators who rose to power before World War 2 were adept at using propaganda to control public opinion and suppress dissent. They used mass media to spread their message and create a cult of personality around themselves.
5. Fear of communism: In many countries, the rise of dictators was fueled by a fear of communism. Many people in Europe and elsewhere were worried about the spread of communism from the Soviet Union, and saw authoritarian leaders as a bulwark against this threat.
In summary, the rise of dictators before World War 2 was the result of a complex set of factors, including economic instability, nationalism, weak democratic institutions, propaganda, and a fear of communism.
