As indicated by her relationship with Hercules and the Olympian gods, Xena lived during the time of ancient Greece. She was the champion of the innocent mortal, and she definitely left her mark on Greece; she actually killed most of the Greek gods singlehandedly in a valiant episode known as "the Twilight". However, her historical significance extends well beyond her homeland as well as her home time. In fact, Xena is soley responsible for many of history's most dramatic episodes.

One of Xena's most bitter enemies was Julius Caesar. As a pirate (Xena also had a very interesting and extensive past), she had helped Caesar rise to power in Rome; the heartless tyrant that he was, Caesar soon betrayed her in a terrible leg-breaking scene and left her for dead. In the days of her later glory (i.e. the Warrior Princess era), she battled the emperor on several fronts. She defended innocent lands against his ever-invading army, including Britannia and Gaul. She also aided Pompey in his strife against Caesar. Finally, although she was ultimately crucified by the Romans in the same episode, she provoked Brutus to lead the infamous assasination in the Senate.

Shortly after coming back to life, Xena once again fought the Romans; this time she was defending the mysterious land of Egypt. Upon hearing of her dear friend Cleopatra's death, Xena rushed to Egypt and secretly took her place. It was at this time that she had her infamous love affair with Marcus Antony under the guise of Cleopatra.

Far away, in the land of Chin, Xena spread the wisdom of Taoism and brought about the fall of the Ming Dynasty. Xena had long ago been befriended by Lao Ma, wife of Lao Tzu and creator of Taoism (she had published her teachings in the name of her husband because of gender inequality). Using the teachings of Lao Ma, Xena harnessed metaphisical power from the execution table and destroyed Ming Tien, the last Ming emperor, thus allowing a republic to rise in his place. Xena later returned to Chin to fight a tyrannical army led by the spirit of Ming Tien; once again using the power of Taoism, she turned the whole army into inanimate Terra Cotta warriors with a blast of pure love.

In the North lands, during the rein of the Norse gods, Xena had been the prized Valkyrie of Odin. However, by accident she had transformed her companion Grenhilda into a horrible monster. Xena later returned to the cold North to slay a murderous beast known as Grendel, who turned out the be the child of Grenhilda. Xena, aided by a young warrior called Beowulf, rid the peaceful villages of these two fiends and defeated the selfish Odin.

Perhaps Xena's most significant contribution to history was the spread of Christianity. Xena and Gabrielle met the prince of peace (called Eli in the series) on a trip to India, where they learned to support the way of universal love. They protected Eli from the armies of an evil god who opposed him, thus allowing him to spread his message and heal the sick. It was Eli who revived Xena and Gabrielle after they had been crucified. And after Eli died for the protection of others, Xena defended his followers everywhere from the Romans. It was also Xena's daughter who participated in the first baptism. And it was on a direct mission from God (Xena and the archangels knew each other from their companionship in the battle between Heaven and Hell) that Xena gained the ability to slay gods and brought about the Twilight.

Xena has molded much of history's course in many parts of the world. Without her, we might still be slaves to the Romans, or even the evil god Dahak.
