After regaining control over the dissident governors, Abd-ar-Rahman III tried to conquer the remaining Christian kingdoms of the Iberian peninsula, attacking them several times and forcing them back beyond the Cantabrian Mountains. Abd-ar-Rahman's grandson later became a puppet in the hands of the great Vizier Almanzor (al-Mansur, "the victorious"). Almanzor waged several campaigns attacking and sacking Burgos, Leon, Pamplona, Barcelona, and Santiago de Compostela before his death in 1002.[citation needed]
