Question why did Rome divided into two parts(east and west)?
Answer Hello,
Actually this question, which seems to be so simple, is very broad, instead, as it would need a long explanation so that you can understand the numerous complex reasons that caused the final division of the Roman Empire in Western Roman Empire (West) and Eastern Roman Empire (East), after the death of the emperor Theodosius I who was the last emperor of both the Eastern and Western Roman Empire.
After his death in 395 AD, the two parts split permanently, as Arcadius, his elder son, received the East (capital city Constantinople aka Byzantium), and Honorius, the younger son, received the West.
From then on there were two Roman Empires: Western Roman Empire which collapsed in 476 AD under the assault of the Barbarian migrations and invasions, and Eastern Roman empire (known as the Byzantine Empire) that fell to Ottoman Turkish onslaughts in 1453.
In short, the reason why Theodosius divided the Roman Empire between his sons, leaving the eastern part to Arcadius and the western to Honorius, was that the empire had become too large for any one emperor to rule effectively the distant provinces, so that the object of the division was to clarify and strengthen the administration of both Oriental and Occidental parts, which therefore could have held out against the attacks of barbarian peoples such as Vandals, Visigoths, Ostrogoths, Longobards, etc.
This is what I can tell you very briefly, of course!
Bye,
Maria
