Constantine the Great designated Byzantium as his imperial capital, redeveloped it and renamed it Constantinople (City of Constantine). Prior to this this city was not an imperial capital. The imperial capital in the eastern part of the Roman Empire was Nicomedia (in north-western Turkey), jut some 60 miles east of Byzantium.
Theodosius I. the Great 347-395 became Roman Emperor in 388 AD and ordered the Roman Empire to be divided after his death between his incompetent sons Honorius who took over the West Roman Empire and Arcadius who reigned over East-Rome or Byzance with his capital Constantinople.
