Overview
The office of the Domestic of the Schools was a senior military post of the Byzantine Empire, extant from the 8th century until at least the early 14th century. Originally simply the commander of the Scholai, the senior of the elite tagmata regiments, the Domestic quickly rose in prominence: by the mid-9th century, its holders essentially occupied the position of commander-in-chief of the Byzantine army, next to the Emperor. The office was eclipsed in the 12th century by that of the Grand Domestic, and in the Palaiologan period (13th–15th centuries), it was reduced to a purely honorary, mid-level court dignity.
History
The first holder of the office of Domestic of the Schools first appears in the sources (the chronicle of Theophanes the Confessor) for the year 767, shortly after the creation of the . These were elite cavalry regiments stationed in or around the capital Constantinople, commanded by officers titled "Domestics" (δομέστικοι, ) and distinct from the provincial armies of the themes under their respective . The Schools was the senior tagma, tracing their origin to the Scholae Palatinae established by Constantine the Great and originally placed under the command of the magister officiorum. The historian J.B. Bury has traced a reference to a certain Anianos, "Domestic of the magister", in the Chronicon Paschale for the year 624, and considers this official to be the predecessor of the Domestic of the Schools. As the magister officiorum was gradually deprived of some of his functions in the 7th and 8th centuries, the Domestic apparently became an independent official. The Kletorologion of 899 lists his subordinate officials as comprising his deputy or (τοποτηρητής), the secretary or (χαρτουλάριος), the head messenger or (πρόξιμος) and the other messengers (μανδάτορες, ), as well as the various subordinate officers of the regiment (cf. the article on the Scholae Palatinae).
In the 9th century, the office of the Domestic, or "Domesticate" (δομεστικάτον, ), of the Schools rose in importance and its holder was often appointed as the head of the army in the absence of the emperor. However, this role was not yet enshrined: it depended rather on the abilities of the current Domestic, and other generals of inferior rank were sometimes entrusted with supreme command instead.
