Before 730 Odo allied with the Muslim ruler of Catalonia, Uthman ibn Naissa (also known as Munuza). The greatest threat to Duke Odo was his Frankish neighbor in the north. Odo married his daughter to Munuza and Arab raids in Aquitaine temporarily ended, enabling him to focus on the northern threat. In 731 Munuza rebelled against the new "wali" of al-Andalus, Abd al-Rahman al-Ghafiqi. Abd al-Rahman defeated him, and to punish Odo for his alliance he launched a raid on Aquitaine. Remembering the Battle of Toulouse, he crossed the Pyrenees west the city and defeated Odo's army in Bordeaux. With Bordeaux captured, the Arabs moved north towards the sacred Frankish abbey of Tours. Odo requested Frankish help; Charles Martel, leader of the Franks, mustered an army and met the Arabs near Poitiers. On 25 October 732, at the Battle of Poitiers, the Arabs were defeated and Abd al-Rahman died on the field. The scholars of Charlemagne, grandson of Charles Martel, extensively chronicled the battle.
