How Fascist Italy Threatened World Peace in the 1930s

Mussolini's Italy destabilized the interwar order through four aggressive acts:

1. Invasion of Ethiopia (1935): Defied League of Nations; used chemical weapons; exposed League's impotence.
2. Rome-Berlin Axis (1936): Formal alliance with Nazi Germany; created a fascist bloc threatening European balance.
3. Spanish Civil War Intervention (1936–39): Sent 70,000+ troops, planes, tanks to Franco's Nationalists; tested blitzkrieg tactics; deepened European polarization.
4. WWII Axis Partnership (1940): Joined Germany in war; invaded France, Greece, Yugoslavia, North Africa; expanded conflict globally.

Italy's revisionist ambitions (Mare Nostrum, new Roman Empire) and alignment with Hitler turned regional aggression into world war catalyst. The League's failure to stop Ethiopia emboldened both dictators.
