Theodosius I (11 January 347 – 17 January 395), also known as Theodosius the Great, was Roman emperor from 379 to 395. He won two civil wars and was instrumental in establishing the Nicene Creed as the orthodox doctrine for Nicene Christianity. Theodosius was the last emperor to rule the entire Roman Empire before its administration was permanently split between the Western Roman Empire and the Eastern Roman Empire. He ended the Gothic War (376–382), but did so on terms disadvantageous to the empire, with the Goths remaining politically autonomous within Roman territory, albeit as nominal allies.
Theodosius suffered from a disease involving severe edema.[109] He died in Mediolanum (Milan) on 17 January 395, and his body lay in state in the palace there for forty days.  His funeral was held in the cathedral on 25 February. In the presence of Stilicho and Honorius, Bishop Ambrose delivered the panegyric De obitu Theodosii, which praised Theodosius's suppression of paganism.
