The title of Grand domestic (Greek: μέγας δομέστικος, romanized: mégas doméstikos) was given in the 11th–15th centuries to the commander-in-chief of the Byzantine army, directly below the Byzantine Emperor. It evolved from the earlier office of the domestic of the Schools, and came to rank as one of the senior dignities in the Byzantine state during the last centuries of its existence. From Byzantium, it was also adopted by the breakaway Empire of Trebizond, as well as by the 14th-century Serbian Empire.
