Early history

Diana, Princess of the Amazons of Earth-Two, was born on the mystical Paradise Island several hundred years before becoming known as Wonder Woman. Isolated from the cruelty and corruption of men, the Amazons lived and worked in peace and obeyed the will of Aphrodite and Athena. Longing for a child of her own, Hippolyta (Queen of the Amazons) begged the gods to grant her request and turn her clay statue into a real girl. In sympathy, Aphrodite relented and animated the statue; the girl leaped off the pedestal into her mother's arms. Hippolyta named her for the moon goddess, Diana (who became her godmother).

Hippolyta raised her daughter as an Amazon, with the privileges of royalty. Diana aged slowly, stopping aging when reaching adulthood (as did all Amazons). She surpassed most of her Amazon sisters in skills and intelligence, running faster than a deer at age five and easily uprooting a tree at three.

Diana was a contented Amazon until Captain Steve Trevor crash-landed on Paradise Island. Although she had never seen a man before, Diana was attracted to him (despite his injuries). Violating the island rule against taking in outsiders, Diana brought the unconscious Trevor back to the Amazons in an attempt to save his life. In response to her pleas, Hippolyta used the healing Purple Ray on Trevor and saved his life.

Discovering that the outside world was at war, Diana wanted to help stop it. Hippolyta refused, saying that they should not involve themselves in the ways of outsiders. However, the goddesses Aphrodite and Athena appeared to Hippolyta; they said it was time for an Amazon to travel to "Man's World" and fight the Nazis. Ares felt that he ruled the world; Aphrodite wanted to help America win, claiming it was the last citadel of democracy. A tournament was held to determine the Amazon champion; although forbidden by Hippolyta to participate, Princess Diana concealed her identity with a mask. After winning all the contests Diana revealed her identity to her mother, who feared she would never see her daughter again.

However, Hippolyta allowed her daughter to dress as Wonder Woman and travel to the outside world. Diana returned Steve Trevor to the United States, adopting the identity of a U.S. Army nurse (Diana Prince) so she could stay with Trevor as he recovered; she helped him against a Japanese agent.

Diana began to appear publicly as Wonder Woman. As Earth-Two Diana Prince, she joined the U.S. Navy as a lieutenant and became Col. Darnell's secretary. In actual Golden Age comics, the character joins the U.S. Army and in one occasion returned to nursing. The real Diana Prince later returned and tried to assume Diana's role, since her inventor husband was having financial trouble selling his weapon to the army. Wonder Woman saved Diana when she is kidnapped by a Japanese agent trying to steal the weapon; when it is successful Diana Prince began using her married name, leaving Wonder Woman in her identity.

Diana continued fighting crime with the Justice Society of America (on Earth-Two) as their first female member, although she was relegated to secretarial work for the Justice Society (despite her super powers). She was shown taking dictation and typing the team's minutes as Wonder Woman. Diana rejoined the team when it reformed and expanded (as the All-Star Squadron). She continued fighting crime after the war and resisted being recalled to Paradise Island, preferring to surrender her immortality rather than her independence.
