Droungarios of the Watch

The Droungarios of the Watch (Medieval Greek: δρουγγάριος τῆς βίγλης/βίγλας, romanized: droungarios tēs viglēs/viglas), sometimes anglicized as Drungary of the Watch, was originally a senior Byzantine military post. Attested since the late 8th century, the droungarios commanded the Vigla or "Watch", one of the elite professional cavalry regiments (tagmata) of the middle Byzantine period, and was in charge of the Byzantine emperor's personal security. From c. 1030, the office was disassociated from its military origin and was transformed into a senior judicial position, thereafter usually referred to as the Grand Droungarios of the Watch (μέγας δρουγγάριος τῆς βίγλης/βίγλας, megas droungarios tēs viglēs/viglas). The office continued to exist as a mostly honorific court dignity in the Palaiologan era, until the very end of the Byzantine Empire in the mid-15th century.
