Question

What was the reason to start world war two ??

Answer 1

The two dates most often mentioned as “thebeginning 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.

Answer 2

Among the causes of World War II were Italian fascism in the 1920s, Japanese militarism and invasion of China in the 1930s, and especially the political takeover in 1933 of Germany by Adolf Hitler and his Nazi Party and its aggressive foreign policy. The immediate cause was Britain and France declaring war on Germany after it invaded Poland in September 1939.
