Remigius of Rouen was an 8th-century archbishop and the illegitimate son of the Frankish leader Charles Martel. Although he received a court education, he did not inherit any of his father's estate, as the patrimony was reserved for his legitimate brothers. He served as the third archbishop of Rouen starting in 755. Throughout his career, he supported his half-brother, Pepin the Short, in various political and religious endeavors across Francia and Italy.
