The orderly system of two senior and two junior emperors endured until Constantius died in July 306, and his son Constantine was unilaterally acclaimed augustus and caesar by his father's army. The Constantinian dynasty's emperors retained some aspects of collegiate rule; Constantine appointed his son Constantius II as another caesar in 324, followed by Constans in 333 and his nephew Dalmatius in 335, and the three surviving sons of Constantine in 337 were declared joint augusti together, and the concept of the division of the empire under multiple joint emperors endured until the Fall of the Western Roman Empire. ./cache/en-wikipedia-org-1995.html ./txt/en-wikipedia-org-1995.txt
