The main allies of each side in World War II were the countries that made up the Axis and the Allies. The three principal participants in the alliance that eventually came to be known as the Axis were Germany, Italy, and Japan.
The alliance between the two nations was both a cause and a result of the world political and economic problems of the 1930s as the far-right governments of Nazi Germany and Imperial Japan felt more and more empowered to disobey and disrupt the international order.
Analysts praised Germany for its respect for military might, geographical expansion, and charismatic leadership in relation to Japan. Germany and Japan were recognized as two powerful nations.
Germany, Italy, and Japan come together to form the Axis powers on September 27, 1940, as the Tripartite Pact is signed in Berlin. The Pact provides for mutual assistance in the event that any of the signatories be attacked by a nation not already engaged in hostilities.
