The Institutes of Justinian (Dodo Press) Book

Flavius Petrus Sabbatius Iustinianus (AD 483-565), known in English as Justinian I or Justinian the Great, was the second member of the Justinian Dynasty (after his uncle, Justin I) and Eastern Roman Emperor from 527 until his death. He is considered a saint amongst Eastern Orthodox Christians, and is also commemorated by some Lutheran Churches; at the other end of the scale, his contemporary, Procopius, viewed Justinian as a cruel, venal, and incompetent ruler. One of the most important figures of Late Antiquity, Justinian's rule constitutes a distinct epoch in the history of the Eastern Roman Empire. The impact of his administration extended far beyond the boundaries of his time and empire. Justinian's reign is marked by the ambitious but ultimately failed renovatio imperii, or "restoration of the empire". This ambition was expressed in the partial recovery of the territories of the Western Roman Empire, including the city of Rome itself. A still more resonant aspect of his legacy was the uniform rewriting of Roman law, the Corpus Juris Civilis, which is still the basis of civil law in many modern states.
