The roots of Spain’s policy of attempted exclusion of the foreigner from her New World possessions, whether in trade or in immigration, reach deep into the Iberian religious consciousness of the fifteenth century. The religious pulse of the Catholic Kings was beating strongly and quickly as a result of the coincidence of the momentous events of the year 1492: expulsion of the Jews, conquest of Granada from the Moors, and the discovery of the New World. It is not surprising that the Spanish conception of religiosity should have been linked inseparably with the attitude of exclusion of the foreigner. Expulsion of the hated infidel-foreigner Moor from Spain was integrally associated with the Jews, since the latter had often been in close cooperation with the former (The fact that they had also cooperated with their rulers in Christian-held parts of Spain was swept aside in wake of the religious zeal of the Reconquista.). On the one hand, there was the religious cause of Catholic Christianity to be served, and, on the other, the secular goal of the consolidation of Castilian rule throughout the Spanish portion of the Iberian Peninsula.
