September 1st, 1939 ~ September 2nd, 1945

While Japan had been at War with China for nearly two years, 

the World War is said to have started when Germany invaded Poland

causing France and the United Kingdom to declare war against Germany.

The United States became involved in the war as combatants after the bombing

of Pearl Harbor on December 7th, 1941.

This was a true Global conflict, with  battles fought on

every continent except Antarctica, and casualties are said

to number between 50 and 85 MILLION people.
