Sayf al-Dawla
Sayf al-Dawla took part in battles with the Almoravids in Jaén, Granada and Murcia, and also fought against Alfonso the Battler. In 1135 he attended Alfonso VII's imperial coronation in León. He was defending the southern border in 1146, when Alfonso VII sent some of his leading knights—Manrique de Lara, Ponce de Cabrera and Armengol de Urgel—to assist him. In a dispute with the Spaniards, Sayf al-Dawla was killed during the battle of Chinchilla, near Chinchilla de Montearagón.
