• General Notes

      Emperor of Rome in the East 378-394
      Emperor of Rome 394-395
      Theodosius was the son of the famous general Flavius Theodosius and was born in Spain. As a young man, he often accompanied his father in the British campaigns, but when he later died Theodosius retired to Spain. When the Roman Emperor Valens in the East died in 378, his co-Emperor Gratian in the West appointed Theodosius to rule the East as Emperor. In 382, Theodosius finally compromised with the invading Visigoths that they could remain in the Empire as long as they served in the army.
      When the Roman Emperor Gratian died in 383, Theodosius recognized the usurper Maximus as Emperor in the West with the exception of Italy, where Valentinian II ruled as Emperor. In 388, Maximus attacked Theodosius, however Theodosius defeated and killed him, returning sole rule fo the West to his co-Emperor Valentinian. In 392, Valentinian's general Arbogast killed the Western Emperor and gave the crown to Eugenius as a puppet ruler in his place. Theodosius marched to Italy and defeated the two pretenders in 394, becoming the first sole Roman Emperor since the Emperor Jovian died in 364. He formally divided the Roman Empire on his death permanently into two separate, independent empires of the West and the East. He was succeeded by his sons Arcadius and Honorius to the East and West respectively.
