The Foederati, the Phoideratoi, and the Symmachoi of the Late Antique East (ca. A.D. 400-650)

Abstract

This thesis is a systematic examination of the use of the term phoideratos in Greek and how it relates to the Greek word symmachos. The term was recognized as not precisely equivalent to its Latin cognate foederatus over a century ago by Jean Maspero, but no complete study of every use of the term has been made until now. This has been facilitated by the Thesaurus Linguae Graecae, an online database of searchable Greek texts. These terms are important since they provide a framework within which foreigners came to serve the Roman army. They also reveal the changing nature of that army, and how the foederati, formerly allies who came to serve the Roman state in exchange for a combination of land, supplies, and cash became the phoideratoi, an elite regular unit in the Roman army. Meanwhile, symmachos came to refer to those who were formerly called phoideratoi. This interpretation is crucial since some modern historiography has considered the phoideratoi of the sixth century as equivalent to the foederati of the fourth.
