When Peter the Second became King of Aragon and Catalonia, he determined to force the kings of Tremicen and Tunis to pay the tribute. An expedition was sent to Barbary, and as a result Miraboaps, the King of Tunis, was driven from the throne and his brother Mirabusach was put in his place. The latter pledged himself to pay the tribute, and signed a treaty with the Aragonese in which he granted them important rights and privileges in his kingdom. Some time later Miraboaps fomented a rebellion in Bugia and Constantine against his brother and succeeded in making himself king of these two cities. When he died he divided between his two sons, Mirabosecri and Bugron, the territory over which he ruled. The former became King of Bugia and the latter ruler over Constantine. But Mirabosecri was not satisfied; he wished to hold sway over Constantine also, and accordingly he made preparations to take that city from his brother. Bugron saw that he could offer but feeble resistance against the ambition of his brother. So he sent messengers to King Peter to inform him that he wished to become a Christian and a subject of the crown of Aragon. This message brought great joy to the heart of the king, who immediately began to build many ships to transport a large army to Africa. So extensive were his preparations that the lords and princes, Christians as well as Saracens, who held territory along the seas, became alarmed, for he told no one what he intended to do. The English king, the French king, and the Pope made inquiries, but he would not reveal his plans. Not until the expedition was far out upon the sea did the commanders of the ships receive instructions as to their destination. When Bugron was informed that the army of the King of Aragon was on its way, he became elated and disclosed to some of his intimate friends what he purposed to do, whereupon they arose in great wrath and cut off his head. King Peter’s army landed at Alcoyll, not far distant from Bugia. The king was shocked when he heard of Bugron’s tragic death, but he concluded, nevertheless, to stay there and wage war upon the Saracens. Fortifications were immediately constructed. Formidable forces of Moors came to attack the Christians, but were always repulsed. Troops from the vast Aragonese army made incursions into the surrounding country, and soon none of the enemy could be found for miles around. King Peter was highly pleased with this excellent beginning, and it did not seem to him that the conquest of all Barbary would be a difficult task if the Pope would only furnish sufficient money to pursue the undertaking to a successful issue. Accordingly he sent an ambassador to Rome to secure this necessary financial assistance. Let us quote a few lines of the ambassador’s petition to the Pope:
