By Spanish law strangers were forbidden to resort to, or reside in, the Indies without express permission of the king. By law, moreover, they might not trade with the Indies from Spain, either on their own account or through the intermediary of a Spaniard, and they were forbidden even to associate with those engaged in such a trade. Colonists were stringently enjoined from having anything to do with them. In 1569 an order was issued for the seizure of all goods sent to the colonies on the account of foreigners, and a royal _cedula_ of 1614 decreed the penalty of death and confiscation upon any who connived at the participation of foreigners in Spanish colonial commerce.[33] It was impossible, however, to maintain so complete an exclusion when the products of Spain fell far short of supplying the needs of the colonists. Foreign merchants were bound to have a hand in this traffic, and the Spanish government tried to recompense itself by imposing on the out-going cargoes tyrannical exactions called "indults." The results were fatal. Foreigners often eluded these impositions by interloping in the West Indies and in the South Sea.[34] And as the _Contratacion_, by fixing each year the nature and quantity of the goods to be shipped to the colonies, raised the price of merchandise at will and reaped enormous profits, the colonists welcomed this contraband trade as an opportunity of enriching themselves and adding to the comforts and luxuries of living. From the beginning of the seventeenth century as many as 200 ships sailed each year from Portugal with rich cargoes of silks, cloths and woollens intended for Spanish America.[35] The Portuguese bought these articles of the Flemish, English, and French, loaded them at Lisbon and Oporto, ran their vessels to Brazil and up the La Plata as far as navigation permitted, and then transported the goods overland through Paraguay and Tucuman to Potosi and even to Lima. The Spanish merchants of Peru kept factors in Brazil as well as in Spain, and as Portuguese imposts were not so excessive as those levied at Cadiz and Seville, the Portuguese could undersell their Spanish rivals. The frequent possession of Assientos by the Portuguese and Dutch in the first half of the seventeenth century also facilitated this contraband, for when carrying negroes from Africa to Hispaniola, Cuba and the towns on the Main, they profited by their opportunities to sell merchandise also, and generally without the least obstacle.
