encourage advances in shipbuilding and navigation, and then voyages of exploration.
The Spanish and the Portuguese came to the Americas to pursue dreams of empire, both secular and religious.
Although the Portuguese acquired Brazil under the Treaty of Tordesillas (1494), the Spanish were the principal Iberian power in the Americas. Their religious aims were simple: to win these lands and peoples for Catholicism. Their secular aims included bringing Central and South America under their imperial governance to augment the power of Spain in world affairs, seeking great wealth (both the gold and gems that were rumored to abound in the Americas), and gratifying their individual ambitions for power and glory (especially in a stratified society like Spain, the Americas offered intoxicating opportunities for social and political advancement). The Spanish colonists were conquistadores
(conquerors).
The French also came to the Americas for wealth and power, but their methods were different. They did not seek to conquer the regions they explored and laid claim to only to repel the competing claims of rival powers like Spain and England and to establish a foothold for themselves in the American continents (a pattern followed as well by the Dutch and the Swedish, who sought to establish colonies as international economic bases, rather than as permanent settlements). The traditional view is that, because the French did not engage in a full-scale colonizing enterprise like that of the English, they missed a priceless opportunity.
On the other hand the English were laggards in the race for the Americas, but, because they ultimately changed their understanding of the nature and purpose of colonies, the English colonies eventually were among the most successful in the Americas. At first, English explorers sought the same kinds of benefits that animated the Spanish, Portuguese, and French enterprises discovery of gold, jewels, and other valuable goods for trade and commerce. Gradually, the English shifted their emphasis to include the plant planting of self-maintaining colonies that, due to the structure of English government, politics, and political theory, acquired a measure of self-governance. As a result, traditional accounts of the English explorations and colonization are remarkably benign, emphasizing the ideas that the founders of the colonies planted "seeds of democracy" in the "New World."
