From a Germanic name meaning "ruler of the people", derived from the elements þeud "people" and ric "power, ruler". It was notably borne by Theodoric the Great, a 6th-century king of the Ostrogoths who eventually became the ruler of Italy. By Theodoric's time the Ostrogoths were partially Romanized and his name was regularly recorded as Theodoricus. The Gothic original may have been Þiudreiks.
