How did the Spanish Civil War affect the relationship between Germany and Italy?

The Spanish Civil War significantly strengthened the relationship between Germany and Italy, as both countries shared a common interest in supporting the Nationalist forces led by Francisco Franco. Adolf Hitler and Benito Mussolini viewed the conflict as an opportunity to test new military strategies and equipment, as well as to counter the spread of communism in Europe. By intervening on the side of the Nationalists, they aimed to expand their influence in Spain and forge a stronger alliance between their regimes.

This collaboration was not only military but also ideological, as both nations were fascist regimes eager to combat leftist ideologies and promote their vision of authoritarianism. The alignment during the Spanish Civil War solidified their political and military ties, which would later contribute to their cooperation during World War II. Thus, the war effectively brought Germany and Italy closer together, reinforcing their roles as allies in the years that followed.
