The Wars of Justinian by Procopius

THE WARS OF JUSTINIAN is Byzantine historian Procopius' most important work. Finished by the early 550s, the work discusses the wars of Justinian's reign against the Persians, Gothic, Vandals, the Nika Riots, and wars against other nations. Procopius witnessed the Nika Riots and journeyed with Justinian's general Belisarius on several of his campaigns to recapture parts of the crumbling Roman Empire.
