Two years before his death in 395 CE Emperor Flavius Theodosius (Theodosius I), divided the Roman Empire into two parts.
Honorius's "throne was guarded by his principal general, Flavius Stilicho, who was successively Honorius's guardian (during his childhood) and his father-in-law (after the emperor became an adult). Despite Stilicho's generalship, the empire lost ground; and after the guardian's execution, Honorius's empire moved towards the verge of collapse" (Wikipedia article on Honorius [emperor]) accessed 05-10-2009).
The Eastern Roman Empire or Byzantine Empire Theodosius placed in the hands of his older son Flavius Arcadius. In 383 Theodosius had declared Arcadius Augustus, and had co-ruled the Eastern half of the Roman Empire with him until 393.
