Therefore, according to legend, Parysatis had all the children of Hydarnes killed and only spared the life of Stateira at the request of her husband.
[4] The queen's mother Parysatis and Stateira tried to be the key political influence on the king; so the women became bitter rivals.
Reportedly the intense hatred between the two women led Parysatis to encourage Artaxerxes II to take on concubines to hurt his wife.
According to another tradition, Parysatis murdered her daughter-in-law because she realized that her son only felt true love for his wife.
Plutarch reports that Parysatis performed the assassination with the help of a loyal servant named Gigis.
