Having exiled their best international traders and kept those remaining as Marranos in constant terror, the Portuguese could not derive the full benefit from that lucrative trade in spices which was to be the reward of their great discoveries. When the sixty years’ captivity――as the domination of Spain over Portugal, from 1580 to 1640, is called――brought, among other disasters, the capture of the Portuguese Indian possessions by the Dutch, the superiority of the latter’s methods were soon apparent. They succeeded with more ease “since, with true commercial spirit, they not only imported merchandise from the East to Holland, but also distributed it through Dutch merchants to every country in Europe; whereas the Portuguese in the days of their commercial monopoly were satisfied with bringing over the commodities to Lisbon and letting foreign nations come to fetch them.” It is not difficult to surmise who were those Dutch merchants who distributed the spices to every country in Europe, when we think of that class of wealthy Marrano immigrants in Holland who were not permitted to follow mechanical pursuits or to engage in retail trade. Holland’s tendency was clearly apparent. The Jews, mostly Portuguese, were permitted to use their wealth, their abilities and their foreign connections to carry on and extend that trade which languished in the hands of those who banished them. The Jews were exceedingly grateful for the opportunity which Holland afforded them to be useful to themselves and to her, and the very effective results of the friendship between the Jews and the Dutch were soon apparent in the ensuing struggle between the latter and the Portuguese over the possession of Brazil.
The Dutch commenced the realization of their ambitious scheme for the conquest of Brazil in the second decade of the seventeenth century, at a time when the large number of Marranos who lived there were terrorized by rumors of the introduction of the inquisition. These rumors became current as early as 1610, when it was reported that the physicians of Bahia, who were mainly new-Christians, prescribed pork to their patients in order to lessen the suspicion that they were still adhering to Judaism. In connection with some of the earliest Brazilian intrigues in favor of the Dutch, mention is made of one Francisco Ribiero, a Portuguese captain, who is described as having many Jewish relatives in Holland. About 1618 the Inquisition in Oporto, Portugal, had arrested all merchants of Jewish extraction. Many of the victims were engaged in Brazilian trade, and the Inquisitor-General applied to the government to assist the Holy Office to recover such parts of their effects as might be in the hands of their agents in Brazil. Accordingly, Don Luis de Sousa was charged to send home a list of all the new-Christians in Brazil “with the most precise information that can be obtained of their property and place of abode.” It seems highly probable that it was the Dutch war alone which prevented the introduction of the dreaded Tribunal in Brazil.
