through a rocky cove, according to the Arabic sources, and the Pisans and Genoese picked off the remaining ships, capturing Mujāhid's mother and his heir. His mother seems to have been originally a European captured and sold into slavery, as she chose to remain with "her people" after her capture on Sardinia. His son and heir, ʿAlī, remained a hostage for a number of years. Those Muslims who survived the wreck of their ships were slaughtered onshore by the local populace. Aftermath According to the Annales pisani, the Pisans and the Genoese fought for control of the island in the aftermath of their victory over Denia. In the first engagement, in Porto Torres, the Pisans were victorious. Pisa secured a papal privilege and strengthened their control over the island by installing monks from Saint-Victor de Marseille and expelling all those monks from rival Monte Cassino whom they could capture. Her interest in curtailing Islamic piracy did not stop at Sardinia. In 1034 her fleet destroyed the pirate base of Bône. The later eleventh-century campaigns of Pisa and Genoa, like the Mahdia campaign of 1087, were performed "for the remission of [their] sins", according to Crusades scholar Jonathan Riley-Smith. Pisa's last outpost on Sardinia was conquered by James II of Aragon, who laid claim to the Kingdom of Sardinia and Corsica, in 1325. Mujāhid never attacked Sardinia again, despite a late medieval story about an invasion of 1021, in which "the Pisans on the island were hunted down". Historically, in 1017 pirates operating out of his taifa failed in a largescale assault on Narbonne. Mujāhid also continued raiding the County of Barcelona and exacting tribute into the 1020s, when the count, Berenguer Ramon I, called upon a Norman adventurer, Roger I of Tosny, to protect him. Following his father's death, ʿAlī continued his policy of raiding Christian territory. The Abbey of Lérins was attacked several times and its monks sold as slaves in the market of Denia. In 1056 Genoa adopted a statute requiring foreigners who were in the city during a time of Muslim aggression to aid the republic (in reconnaissance, for instance). These attacks on the coasts of northern Italy and southern France may have been launched from Corsica. The "evil men" which Pope Gregory VII (1073–85) ordered Bishop Landulf of Pisa (1070–75) to remove from the island may have been Muslims. Denia under Mujāhid's successors did not ignore
