It is uncertain if the Inquisition existed in Castile in the beginning of the fifteenth century; for, though Boniface IX. appointed F. Vicente de Lisboa inquisitor-general, his authority was not recognized, as that kingdom belonged to the party of Benedict XIII., who, after the Council of Constance, was designated as the anti-pope Peter de Luna. The town of Perpignan was the seat of one of the provincial Inquisitions of Aragon, whose jurisdiction extended over the countships of Rousillon and Cerdagne, and over the islands of Majorca, Minorca, and Iviza. Benedict XIII., who was recognized in this part of Spain, divided this province and appointed two inquisitors, who celebrated several _autos-da-fé_, and burnt a considerable number of people. The election of Martin V. having put an end to the great schism of the West, the Portuguese monks ought to have submitted to the authority of the Provincial of Spain, who was then a monk of their nation, named F. Juan de Santa Justa; but the Dominicans who were at Constance persuaded the Pope that his jurisdiction was too extensive, which induced the pontiff to subdivide the province of Spain into three parts: the first part was named the province of Spain, and comprised Castile, Toledo, Murcia, Estremadura, Andalusia, Biscay, and the Asturias de Santillana; the second, Santiago, was composed of the kingdom of Leon, Galicia, and the Asturias of Oviedo; and the third, that of Portugal, extended over all the dominions of the monarch. Martin V. established a provincial Inquisition at Valencia, in 1420, at the request of Alphonso V., King of Aragon; hitherto commissioners had only been sent there. The Inquisitor of Aragon, 1441, was F. Michael Ferriz, and that of Valencia, F. Martin Trilles, who reconciled in their districts several Wickliffites, and condemned many others to be burnt. Several inquisitors succeeded these till 1474, when Isabella, wife of Ferdinand of Aragon, King of Sicily, ascended the throne of Castile, after the death of Henry IV. her brother. John II., King of Aragon, dying in 1479, his son, Ferdinand, united that kingdom to Sicily; he soon after conquered the kingdom of Grenada, which belonged to the Moors, and lastly that of Navarre, which was secured to him by the capitulation of the inhabitants.
