Final answer:
The military force used to crush revolutions in Spain and Italy was primarily caused by the support from Germany and Italy, non-intervention from other countries, and political ideologies and conflicts.
Step-by-step explanation:
The military force used to crush revolutions in Spain and Italy was caused by several factors:
- Support from Germany and Italy: During the Spanish Civil War, Spanish General Francisco Franco led a rebellion against the republican government. Germany and Italy provided troops, weapons, and military support to help Franco's nationalist forces. Hitler and Mussolini saw the conflict as an opportunity to support fascism and test their military capabilities.
- Non-intervention from other countries: Despite an international non-intervention agreement, Germany and Italy violated it and provided support to the nationalist forces. Other countries, like France and Great Britain, pursued a policy of non-intervention, avoiding involvement in the conflict.
- Political ideologies and conflicts: The Spanish Civil War was a battle between fascist forces, led by Franco, and supporters of the republic, including socialists and communists. The conflict represented a larger struggle between different political ideologies and led to heinous acts and casualties on both sides.
