Drungarios

A droungarios, also spelled drungarios (Greek: δρουγγάριος, Latin: drungarius) and sometimes anglicized as Drungary, was a military rank of the late Roman and Byzantine empires, signifying the commander of a formation known as droungos.

Latin-speakers adopted the word drungus - first attested in the early 4th century - either from Gaulish or from a Germanic language. In the late 6th century, the Emperor Maurice (r. 582–602) in his Strategikon used droungos to refer to a specific tactical deployment, usually of cavalry, although still in the general sense of "grouping, division".

The term droungarios (Greek: δρουγγάριος) is not documented before the early 7th century but might have been used as an informal or unofficial designation before that date. The office and the corresponding unit appear to have initially referred to ad hoc arrangements, but during the early 7th century these were formalized, like much of the Eastern Roman army's rank structure. In the new military-administrative theme system, every major division, called a thema (Greek: θέμα), was further divided into tourmai, while each tourma was divided into moirai (Greek: μοίραι) or droungoi, which in turn were composed of several banda. Thus each moira or droungos was the analogue of a modern regiment or brigade, initially circa 1000 men strong (and hence also referred to as a chiliarchia), although on occasion it could rise to 3000 men, and Emperor Leo VI the Wise (r. 886–912) is recorded as having established droungoi of only 400 men for the new smaller themes.
