15 May 392 – 17 Jan 395 Wikipedia: Theodosius I
Flavius Theodosius was born either in Cauca, Gallaecia, Hispania (according to Hydatius and Zosimus) or in Italica, Baetica, Hispania (according to Themistius, Claudius Claudianus, or Marcellinus Comes).
His father was a senior military officer, Theodosius the Elder.
Theodosius, Gratian and Valentinian II issued the Edict of Thessalonica, recorded in the Codex Theodosianus xvi.1.2, on 27 Feb 380. This edict declared Nicene Trinitarian Christianity to be the only legitimate imperial religion and the only one entitled to call itself Catholic. It also banned other religions as being heretical.
In May 381, Theodosius convened the First Council of Constantinople, a council of Christian bishops, with the intent to repair the schism between East and West by drawing the East back to Nicene orthodoxy.
Theodosius died in Milan on 17 Jan 395. He was eventually buried in Constantinople on 8 Nov 395.
