“World war 2”

World War 2 was fought between two groups of countries. On one side were the Axis Powers, including Germany, Italy and Japan.

The two dates most often mentioned as “the beginning of World War II” are July 7, 1937, when the “Marco Polo Bridge Incident” led to a prolonged war between Japan and China, and September 1, 1939, when Germany Invaded Poland, which led Britain and France to declare war on Hitler's Nazi state in retaliation.
