As is well known, the Spanish Inquisition was originally established to investigate suspected cases of reversion to Judaism by baptised Spaniards, but in the century of the Reformation it naturally came to extend its jurisdiction over heretics of all kinds, native and foreign; and many English Protestants who landed on Spanish soil were dismayed to find themselves the objects of its attention. Most of them were sailors or merchants, visiting willingly or by accident those Spanish territories which fell under the jurisdiction of the Inquisition Court in the Canary Islands, some details of which have already been published. The records of this court survived the massive destruction of Inquisition archives in the early nineteenth century; so too did the records of the court at Toledo, which had jurisdiction over most of Central Spain, and which despite its inland position also found itself dealing with a number of Lutherans, Calvinists and Anglicans. In view of the general opinion that Calvinism represented a tougher line in the Reformation, it is interesting to see that all the Calvinists and Anglicans accepted reconciliation with the papacy, while most of the Lutherans resisted the pressures of the Inquisition and were condemned.
