The Axis Powers of World War II was established with the signing of the Tripartite Pact in 1940 and pursued a strongly militarist and nationalist ideology; with a policy of anti-communism.
During the early phase of the war, puppet governments were established in their occupied nations.
The chief leaders were Adolf Hitler of Nazi Germany, Benito Mussolini of Fascist Italy, and Hirohito of the Empire of Japan.
[1][2] Unlike what happened with the Allies, there was never a joint meeting of the main Axis heads of government, although Mussolini and Hitler met on a regular basis.
These countries were not signatories of the Tripartite Pact and thus not formal members of the Axis.
