Muslim conquests from Hispania

The Umayyad troops, under Al-Samh ibn Malik al-Khawlani, the governor-general of al-Andalus, overran Septimania by 719, following their sweep up the Iberian peninsula. Al-Samh set up his capital from 720 at Narbonne, which the Moors called Arbū na. With the port of Narbonne secure, the Umayyads swiftly subdued the largely unresisting cities of Alet, Bé ziers, Agde, Lodè ve, Maguelonne, and Nî mes, still controlled by their Visigothic counts.

The Umayyad campaign into Aquitaine suffered a temporary setback at the Battle of Toulouse (721), when Duke Odo of Aquitaine (also known as Eudes the Great) broke the siege of Toulouse, taking Al-Samh ibn Malik's forces by surprise and mortally wounding the governor-general Al-Samh ibn Malik himself. This defeat did not stop incursions into old Roman Gaul, as Muslim forces, soundly based in Narbonne and easily resupplied by sea, struck eastwards in the 720s, penetrating as far as Autun in Burgundy in 725.

Threatened by both the Umayyads in the south and by the Franks in the north, in 730 Eudes allied himself with the Berber emir Uthman ibn Naissa, called " Munuza" by the Franks, the deputy governor of what would later become Catalonia. As a gage, and to seal the alliance, Uthman was given Eudes's daughter Lampade in marriage, and Arab raids across the Pyrenees, Eudes's southern border, ceased. However, the next year, Uthman rebelled against the governor of al-Andalus, ‘Abd-al-Raḥ mâ n, who quickly crushed the revolt and directed his attention against Eudes. ‘Abd-al-Raḥ mâ n had brought a huge force of Arab heavy cavalry and Berber light cavalry, plus troops from all provinces of the Caliphate, in the Umayyad attempt at a conquest of Europe north of the Pyrenees. According to one unidentified Arab, " That army went through all places like a desolating storm." Duke Eudes (called King by some), collected his army at Bordeaux, but was defeated, and Bordeaux was plundered. The slaughter of Christians at the Battle of the River Garonne was evidently horrific; the Mozarabic Chronicle of 754 commented, " solus Deus numerum morientium vel pereuntium recognoscat ", (" God alone knows the number of the slain"). The Umayyad horsemen then utterly devastated that portion of Gaul, their own histories saying the " faithful pierced through the mountains, trampled over rough and level ground, plundered far into the country of the Franks, and smote all with the sword, insomuch that when Eudo came to battle with them at the River Garonne, he fled."
