What were the names of the two sons of Theodosius I who split the Roman Empire?

The two sons of Theodosius I who divided the Roman Empire after their father's death in 395 AD were indeed Arcadius and Honorius. This division was significant as it formalized the split between the Eastern and Western Roman Empires. Arcadius became the emperor of the Eastern Roman Empire, which would later become known as the Byzantine Empire, while Honorius ruled over the Western Roman Empire.

The decision to split the Empire was not uncommon for the time as the Roman Empire was facing various internal pressures and external threats, making it more manageable to govern in two parts. This division set a precedent for the later history of the Roman Empire and its eventual decline.
