World Army

History
In the year 1939, World War II began. Many countries began preparing in case of an attack. This became more of a concern after Hitler acquired the Spear of Destiny and used it in an attempt to take over the world. The island of Themyscira was invaded and their population was decimated. Their Queen, Hippolyta was forced to enter Man's World to end the war.

The worst of these attacks were done by the Japanese. On December 7th of 1941, Pearl Harbor was bombed and many were killed. The following day, the United States declared war on Japan and shortly thereafter, the US also declared war on Nazi Germany.

In the weeks following, Roosevelt and Churchill made an agreement and the heroes of the United States and the United Kingdom became the World Army. In the words of FDR, "they truly are an All-Star Squadron."

The World Army disbanded after the end of World War II. The Spear of Destiny was stolen by Vandal Savage.
