A Hungarian raid in Spain took place in July 942. This was the furthest west the Hungarians raided during the period of their migration into central Europe; although, in a great raid of 924–25, the Hungarians sacked Nîmes and may have got as far as the Pyrenees.The only contemporary reference to the Hungarians crossing the Pyrenees into Spain is in al-Maʿsūdī, who wrote that "their raids extend to the lands of Rome and almost as far as Spain". The only detailed description of the raid of 942 was preserved by Ibn Ḥayyān in his Kitāb al-Muqtabis fī tarīkh al-Andalus (He Who Seeks Knowledge About the History of al-Andalus), which was finished shortly before his death in 1076. His account of the Hungarians relies on a lost tenth-century source. According to Ibn Ḥayyān, the Hungarian raiding party passed through the Kingdom of the Lombards (northern Italy) and then through southern France, skirmishing along the way. They then invaded Thaghr al-Aqṣā ("Furthest March"), the northwestern frontier province of the Caliphate of Córdoba. On 7 July 942, the main army began the siege of Lleida (Lérida). The cities of Lleida, Huesca and Barbastro were all ruled by members of the Banū Ṭawīl family. The first two were ruled by Mūsa ibn Muḥammad, while Barbastro was under the control of his brother, Yaḥyā ibn Muḥammad. While besieging Lleida, the Hungarian cavalry raided as far as Huesca and Barbastro, where they captured Yaḥyā in a skirmish on 9 July.
