Additional Axis Armies

The Axis powers, also known as "Rome–Berlin–Tokyo Axis", grew from a series of treaties through the 1930s. Initially between Germany and Italy. A declaration by Benito Mussolini late in 1936 stated that all other European countries would from then on rotate on the Rome–Berlin axis, thus creating the term "Axis".

Japan joined the pact with the signing of an anti-communist treaty and by 1939 the "Rome–Berlin Axis" had become a military alliance. During World War II, the Axis presided over territories that occupied large parts of Europe, North Africa, and East Asia.
