East Roman Army - Sources

Sources

Much of our evidence for the East Roman army's deployments at the end of the 4th century is contained in a single document, the Notitia Dignitatum, compiled c395-420, a manual of all late Roman public offices, military and civil. The main deficiency with the Notitia is that it lacks any personnel figures so as to render estimates of army size impossible. However, the Notitia remains the central source on the late Army's structure due to the dearth of other evidence.

The bulk of the evidence for the East Roman army is from the period of emperor Justinian I (reigned 527-65), who undertook a major programme to reconquer the lost territories of the fallen Western Roman Empire, which had collapsed in 476AD and been replaced by barbarian successor kingdoms. Justinian succeeded in recapturing Italy, Africa and southern Spain. These wars, and the career of Justinian's generalissimo, Belisarius, are described in detail by the 6th century historian Procopius.

The third major source for the East Roman army are the legal codes published in the East Roman empire in the 5th and 6th centuries: the Theodosian code (438) and the Corpus Iuris Civilis (528-39). These compilations of Roman laws dating from the 4th century contain numerous imperial decrees relating to all aspects of the regulation and administration of the late army.
