Between 1796 and 1809, an array of pro- and anti-mining discourses unfolded in response to a proposal to mine gold in the former Jesuit mission territories of Chiquitos. In the last years of the 18th and the beginning of the 19th centuries, Chiquitos, in addition to being a region formerly known for its network of Jesuit missions, was a frontier of colonial settlement on a transimperial boundary characterized by an ambiguous jurisdictional status. These geographical particularities molded in significant ways the arguments presented by supporters as well as detractors of gold mining. Whether they inclined to the negative or positive, colonial discourses relating to mines and mineral extraction were tethered to geography and shaped in relation to ideas and beliefs about the characteristics of particular territories.
The arrival of Christopher Columbus in the northern Caribbean with three Spanish ships in October 1492 marked the beginning of continuing European contact with the Americas. With his second voyage of 1493 permanent European occupation of the Caribbean began, with enormous consequences for the peoples and ecology of the region. Failing to encounter the wealthy trading societies that Columbus had hoped to find by reaching Asia, Europeans in the Caribbean soon realized that they would have to involve themselves directly in organizing profitable enterprises. Gold mining in the northern islands and pearl fishing in the islands off the coast of Tierra Firme (present-day Venezuela) for some years proved enormously profitable but depended on Spaniards’ ability to exploit indigenous labor on a large scale. The imposition of the Spanish encomienda system, which required indigenous communities to provide labor for mining and commercial agriculture, and the large-scale capture and transportation of Native Americans from one locale to another wrought havoc among the indigenous peoples of the Caribbean and circum-Caribbean, resulting in high mortality and flight. Spaniards in the islands soon sought to supplement indigenous labor by importing African slaves who, in the early 16th century, became a significant if not always easily controlled presence in the region. From the earliest years the Spanish Caribbean was a complex, dynamic, and volatile region characterized by extensive interaction and conflict among diverse groups of people and by rapid economic and institutional development. Although the islands became the launching grounds for subsequent Spanish moves to the nearby mainland, throughout the 16th century and beyond they played a crucial role in sustaining Spain’s overseas empire and integrating it into the larger Atlantic system.
Between the arrival of Columbus and the last slave voyage to Cuba in the 1860s, over 12 million enslaved Africans were carried and sold in the Americas. Brazil received almost half of all these captives, most of them during the colonial period. An efficient slave-trading system allowed slavery to become a major force in the development of Portuguese America. The institution became pervasive throughout the colony in the three centuries comprising the colonial era, with important differences across time and space. Some of the major exports produced by African slaves in Brazil, such as sugar, tobacco, and gold, had various global impacts. They also stimulated important domestic developments, such as the creation of internal markets and the growth of cities like Salvador and Rio de Janeiro, with African slaves playing essential roles everywhere. Moreover, the history of African slavery became intertwined with the history of native Brazilians in peculiar ways.
