The state of the Inquisition in the kingdom of Aragon, at the accession of Ferdinand and Isabella, has been shown in a preceding chapter. This tribunal was then introduced into the kingdom of Castile, after having been reformed by statutes and regulations so severe, that the Aragonese violently resisted the fresh burdens which were imposed on them. This is the Inquisition which has reigned in Spain since the year 1481, which was destroyed, to the satisfaction of all Europe, and which has since been re-established to the grief of all enlightened Spaniards. The war against the Albigenses was the first cause of the establishment of the Inquisition; and the pretended necessity of punishing the apostacy of the newly-converted Spanish Jews, was the reason for introducing it in a reformed state. It is important to remark, that the immense trade carried on by the Spanish Jews had thrown into their hands the greatest part of the wealth of the Peninsula; and that they had acquired great power and influence in Castile under Alphonso IX., Peter I., and Henry II.; and in Aragon under Peter IV. and John I. The Christians, who could not rival them in industry, had almost all become their debtors, and envy soon made them the enemies of their creditors. This disposition was fostered by evil-minded men, and popular commotions were the consequence in almost all the towns of the two kingdoms. In 1391, five thousand Jews were sacrificed to the fury of the people in different towns. Several were known to have escaped death by becoming Christians; many others sought to save themselves in following their example; and in a short time more than a million persons renounced the law of Moses to embrace the Christian faith. The number of conversions increased considerably during the ten first years of the fifteenth century, through the zeal of St. Vincent Ferrier and several other missionaries; they were seconded by the famous conferences which took place in 1413 between several Rabbis and the converted Jew, Jerome de Santafé. The converted Jews were named _New Christians_; they were also called Marranos, or the cursed race, from an oath which the Jews were in the habit of using among themselves. As the fear of death was the cause of most of these conversions, many repented, and secretly returned to Judaism, though they outwardly conformed to Christianity. The constraint to which they were obliged to submit was sometimes too painful, and several were discovered. This was the ostensible reason for the establishment of a tribunal which gave Ferdinand an opportunity of confiscating immense riches, and which Sextus IV. could not but approve, as it tended to augment the credit of the maxims of the court of Rome; it is to these projects, concealed under the appearance of zeal for religion, that the Inquisition of Spain owes its origin.
