After the Battle of Poitiers, Odo was obligated to pay homage to Charles Martel and recognize Frankish authority. The Franks were busy in Burgundy and did not move further south, leaving Odo independent until his death in 735. He was succeeded by his son, Duke Hunald I of Aquitaine (also known as Hunold and Hunaud). Hunald refused to recognize Charles Martel, who sent his troops south and captured Bordeaux in 736. Hunald was forced to accept Frankish authority, and Martel withdrew his troops from Aquitaine to attack Arab holdings on the Mediterranean coast near Narbonne. In 741 Charles Martel died and was succeeded by his son, Pippin the Short ("Pépin le Bref"). Hunald again rebelled against Frankish authority the following year; after his 745 defeat, he retired to a monastery. He was succeeded by his son, Waifer of Aquitaine (also known as Waifre and Gaifier). Pippin, busy at home and sharing power with his brother, left Waifer in possession of Aquitaine and became sole ruler of the Frankish realm in 747. In 751 he deposed the last Merovingian king and was elected king of the Franks with the support of the pope, founding the Carolingian dynasty.
