Sisygambis

Sisygambis (died 323 BC) was the mother of Darius III of Persia, whose reign was ended during the wars of Alexander the Great. After she was captured by Alexander at the Battle of Issus, she became devoted to him, and Alexander referred to her as "mother".

She may have been the daughter of king Artaxerxes II Memnon, or possibly of his brother Ostanes. If the latter, she married her own brother Arsames (an ancient Achaemenid tradition).[1] Another possibility is that she was the daughter of an Uxian leader.[2] She gave birth to Darius, Oxyathres, and possibly also Stateira I.[1]
