The reader will naturally seek for an explanation of this political enigma, or base intrigue, and its solution is again eminently characteristic of the reign in which it occurred. It will be remembered that the Duke of Braganza had been declared King of Portugal, which kingdom had separated itself from the Spanish domination, causing no small degree of animosity among the Castilians against the Portuguese and all who favored them. The Duke of Escalona, unfortunately, was related to the house of Braganza, and the credulous Philip having heard that his viceroy exhibited some evidences of attachment to the Portuguese, resolved to supercede him by Palafox. Besides this, the Duke committed the impolitic act of appointing a Portuguese, to the post of Castellan of St. Juan de Ulua; and, upon a certain occasion, when two horses had been presented to him by Don Pedro de Castilla, and Don Cristobal de _Portugal_, he unluckily, remarked that he liked best the horse that was offered by _Portugal_! It is difficult to believe that such trifles would affect the destiny of empires, when they were discussed by grave statesmen and monarchs. But such was the miserable reign of Philip IV.;--the most disastrous indeed, in the annals of Spain, except that of Roderic the Goth. Folly like this may justly be attributed to the imbecile king, who witnessed the Catalan insurection, the loss of Rousillon, Conflans, a part of Cordaña, Jamaica, and, above all, of Portugal; and who, moreover, recognized the independence of the Seven United Provinces.
