 In the turmoil after the death of Constantine in 337, in order to establish himself and his brothers, Julian's zealous Arian cousin Constantius II appears to have led a massacre of most of Julian's close relatives.Constantius II allegedly ordered the murders of many descendants from the second marriage of Constantius Chlorus and Theodora, leaving only Constantius and his brothers Constantine II and Constans I, and their cousins, Julian and Gallus (Julian's half-brother), as the surviving males related to Emperor Constantine.Constantius II, Constans I, and Constantine II were proclaimed joint emperors, each ruling a portion of Roman territory.
