Parysatis, the youngest daughter of Artaxerxes III of Persia, married Alexander the Great in 324 BC at the Susa weddings.
Following the Battle of Issus in 333 BC, Parysatis and many of her relatives were captured in Damascus by Macedonian general Parmenion.
[2] It is possible that Parysatis remained at Susa with the women of Darius's family while Alexander led a campaign in India.
By wedding both women, Alexander cemented his ties to both branches of the royal family of the Achaemenid Empire.
[2] If Parysatis were Alexander's wife, then, like Stateira, there was a possibility that she could be – or could claim to be – pregnant with his child, and thus pose a threat to Roxana.
