Question

Quizplus · Accepted Answer

Emperor Constantine is credited with the division of the Roman Empire into two halves, the Western Roman Empire and the Eastern Roman Empire (later known as the Byzantine Empire), through his establishment of a second capital in Byzantium, later renamed Constantinople (modern-day Istanbul). This effectively split the administration of the empire into eastern and western halves.
