Eurystheus ordered Hercules to retrieve the magical girdle of Hippolyta, queen of the Amazons. The girdle was a gift from Hippolyta's father Ares, the god of war, and whoever possessed it would be the greatest warrior. Hercules traveled to the land of the Amazons and was welcomed by Hippolyta, who agreed to give him the girdle. However, Hera made the Amazons believe Hercules had come to kidnap their queen, causing a fight during which Hercules accidentally killed Hippolyta. Hercules completed the task and brought Hippolyta's magical girdle back to Eurystheus.
