It was the same in Aragon. No knight of the cross earned a more brilliant reputation for exploits against the infidel than Jaime I, who acquired by them his title of el _Conquistador_, yet when, in 1260, he gave his nobles permission to serve in a crusade under Alfonso X, he excepted the King of Tunis, and on Alfonso's remonstrating with him he explained that this was because of the love which the King of Tunis bore him and of the truce existing between them and of the number of his subjects who were in Tunis with much property, all of whom would be imperilled.[162] On the accession of Jaime II, in 1291, envoys came to him from the Kings of Granada and Tremecen to renew the treaties had with Alfonso III. To the latter Jaime replied, promising freedom of trade, demanding the annual tribute of 2000 doblas which had been customary and asking for the next summer a hundred light horse paid for three months, to aid him against his Christian enemies.[163] As late as 1405, the treaty between Martin of Aragon and his son Martin of Sicily on the one hand and Mahomet, King of Granada, on the other, not only guarantees free intercourse and safety to the subjects of each and open trade in all ports and towns of their respective dominions, but each party agrees, when called upon, to assist the other, except against allies--Aragon and Sicily with four or five galleys well armed and manned and Granada with four or five hundred cavalry.[164] All these alliances and treaties for freedom of trade and intercourse were in direct antagonism to the decrees of the Church, which in its councils ordered priests every Sunday to denounce as excommunicate, or even liable to be reduced to slavery, all who should sell to Moors iron, weapons, timber, fittings for ships, bread, wine, animals to eat, ride or till the ground, or who should serve in their ships as pilots or in their armies in war upon Christians.[165] It was in vain that Gregory XI, in 1372, ordered all fautors and receivers of Saracens to be prosecuted as heretics by the Inquisition, and equally vain was the deduction drawn by Eymerich from this, that any one who lent aid or counsel or favor to the Moors was a fautor of heresy, to be punished as such by the Holy Office.[166] In spite of the thunders of the Church the traders continued trading and the princes made offensive and defensive alliances with the infidel.
