The Balearic Isles, captured in 1115 by Raymond Berenger III., Count of Barcelona, and afterwards occupied by the surviving leaders of the Almoravide party, now for the first time in their history experienced the effects of Berber invasion. Majorca was devastated by the Mauritanian cavalry, its cities were burnt, and its population enslaved. Minorca and Ivica, profiting by this example, hastened to solicit the clemency of their sovereign, and the heads of the Almoravide chieftains, carefully embalmed with camphor and enclosed in an elegant casket, were sent to Morocco as conclusive evidence that nothing more was to be feared from a crushed and disorganized faction. The propitious beginning of a reign fated to end in ruin and disgrace encouraged the youthful Sultan to undertake enterprises of far greater importance. The truce unwisely conceded by Yakub to the entreaties of the King of Castile had not yet expired. But the deliberate violation of a treaty contracted with an infidel was considered an offence scarcely worthy of absolution by the Christian casuists of that age. Present expediency alone regulated the observation of public engagements. The prince, who, to his own disadvantage, honorably fulfilled the terms of a contract with a Moslem, would have been rewarded with the derision of his subjects and the anathemas of the clergy. Long anterior to the time of Mendoza and Ximenes, who made the broadest application of that infamous principle, its adoption had been approved by both the civil and ecclesiastical powers of Christian Spain, and faith was kept with an unbeliever or a heretic only so long as it suited the convenience of the other contracting party.
