Five years later, in 1474, Isabella’s brother Enrique, the last male of the house of Trastamare, passed away, and his sister succeeded to the throne of Castile, to which she was already entitled. In the ancient city of Segovia, with attendant pomp and ceremony, on the 13th of December, 1474, the heralds proclaimed her Queen of Castile. But her claim was disputed, and there ensued the “war of succession,” only ended by the defeat of the Portuguese at the battle of Toro, after which peace was concluded, with France and Portugal, in 1479. That same year, by the death of his father, John II, Ferdinand succeeded to Aragon and its dependencies, and thus the twain found themselves virtual rulers of the best part of Spain. With the exception of Navarre, which went to Eleanor, Ferdinand’s half–sister, and of the kingdom of Granada, still held by the Moors, united Castile and Aragon may be said to have included all Spain, from the Atlantic east to the Mediterranean, and from the Pyrenees on the north to the Straits of Gibraltar on the south, though each kingdom was independent. By the exercise of consummate skill, patience, and persistence, both in the field of war and in diplomacy, the entire peninsula, with the exception of Portugal, eventually was welded into one kingdom, and the various armies that had so frequently clashed in conflict were placed under one supreme command. This was not accomplished until after many years, but almost from the first these two wise sovereigns bent all their energies to the consummation of their purpose: Isabella in the domestic administration, Ferdinand in war and diplomacy, which was to unite Spain and expel the hated infidel. We will not now pause to inquire their motives, but note only the vastness of the undertaking. More than any other nation, perhaps, the Spanish were divided, one section speaking a French dialect, another the Basque; one province might be aristocratic, another monarchical, and yet another democratic, while every one had its own peculiar laws and rights, called “_fueros_.” To show the feeling of independence which pervaded Aragon, for instance, we may quote the ancient formula used in seating a king on the throne: “We, each of whom is as good as you, and who altogether are more powerful, make you our king as long as you shall keep our _fueros_; otherwise not.”
