  Late Roman Empire: 4th to 7th centuries
  Middle Byzantine Empire: 7th to 11th centuries
  Late Empire: 11th to 15th centuries
context_section_description: Justinian I (527–565), who succeeded Justin and was the last Latin speaking emperor, is generally regarded as the greatest of the Byzantine emperors and another Emperor-Saint. Justinian brought the empire to its greatest years of power and glory before the long decline that set in during the second half of the first millennium as western civilization moved from Late Antiquity into the High Middle Ages.
