Magister militum ("Master of the Soldiers") was a rank used in the later Roman Empire dating from the reign of Constantine. Used alone, it refers to the senior military officer of the Empire, and was held by Stilicho, Ricimer, Odoacer and others. It was also often used with a provincial name, such as the Magister militum per Thracias ("Master of the Soldiers of Thrace"), to indicate a regional position.
