How did the axis powers cause WW2?

The Axis Powers, primarily Germany, Italy, and Japan, contributed to the outbreak of World War II through their aggressive expansionist policies and militarization. Germany's invasion of Poland in 1939, following its earlier annexations and the signing of the Molotov-Ribbentrop Pact with the Soviet Union, directly triggered the war. Italy sought to expand its empire in Africa, while Japan pursued territorial gains in Asia, leading to conflicts with other nations. Their disregard for international agreements and the League of Nations' authority destabilized Europe and Asia, ultimately culminating in a global conflict.
