1492–1824

Although it has received less scholarly attention than firearms, microbes, domestic animals and plants, market economy, and statecraft, alphabetic reading and writing was crucial in the European conquest and colonization of the Americas from the late 15th century on. Unlike the agrarian empires the Spaniards encountered in the Andes and the Mexican highlands, the Portuguese frontier advanced upon tribal peoples who relied exclusively on oral language, such as the Tupi of Atlantic Brazil. These were semi-sedentary horticultural villagers whose entire socio-ecology (myths and knowledge, territoriality, subsistence strategies, etc.) was conditioned by the face-to-faceness and fugacity of spoken words. In turn, their Portuguese colonizers—for a while rivaled by the French, who enjoyed short periods of stable settlement through the early 17th century—were urban-based, oceangoing merchants, bureaucrats, soldiers, and religious missionaries whose organization strictly depended on the durability and transferability of written texts. Even if most of the Portuguese who came to Brazil in the 16th century were themselves illiterate, colonization as a social enterprise framed their actions according to prescribed roles set down in writing (both handwriting and printed script). Thus, the Portuguese colonization of Brazilian native lands and human populations can be interpreted from the point of view of the imposition of an alphabetically organized way of life. Two major dimensions of this “letterscaping” can be discerned as to its impact on Amerindian bodies (human and nonhuman) and modes of understanding. Although the 16th century was only the introductory act in that drama, its historical record shows the basic outlines of the alphabetic colonization that would play out through the early 19th century: native decimation and enslavement, territory usurpation by sesmaria grants, forest recovery in former native croplands (then resignified as “virgin forest”), loss of native ecological knowledge not recorded in writing, disempowerment of native cultural attunement to the wild soundscape, among other processes.

During his breathtaking 19th-century scientific explorations of New Spain (as Mexico was known under Spanish rule), illustrious German scientific traveler Alexander von Humboldt crammed a lifetime of scientific studies into one extraordinary year: exhausting inspections of three major colonial silver mines, prodigious hikes to the summits of most of Mexico’s major volcanoes while taking scientific measurements and botanical samples, careful study of hitherto secret Spanish colonial archives in Mexico City, and visits to recently uncovered archaeological sites of pre-Hispanic cultures. Humboldt wrote voluminously about his Mexican experiences and is an indispensable source of insights into the colony of New Spain on the eve of its troubled birth as independent Mexico a decade later.

From the time that Columbus arrived in the Caribbean until Spain surrendered power over its mainland American colonies in the early 19th century, Spanish and Portuguese colonial mines poured forth vast amounts of bullion, including some gold and a far greater quantity of silver, both in terms of weight and its overall value relative to gold. Fiscal records indicate that Spanish Americans officially refined gold worth approximately 374,000,000 pesos, each consisting of 272 maravedís, whereas the amount of silver produced reached a value of 3,432,000,000 pesos (to these figures need to be added contraband output, estimated to have been around 17–20 percent). In other words, the colonies refined nine times more silver than gold. While Columbus, Cortés, and other earlier explorers may have fantasized primarily about gold, it was the flood of American silver that touched off the price revolution in Europe and monetarized the emerging world economy, especially because China had a voracious appetite for silver, not gold. At the same time in the American colonies, mining distorted economic life because of the incentives the industry received from a silver-hungry monarchy. Mining also had profound consequences for indigenous society, severely exploited to provide workers for the mines and refining mills.

Colonial refiners used two methods to beneficiate their silver ores, smelting and amalgamation. Smelting was suitable for all types of American silver ores but required large amounts of fuel to heat the ovens. It remained widely used throughout Mexico during the entire colonial period. Amalgamation was a newer technology, adapted to American ores during the mid-16th century. Although it did not require large quantities of charcoal and other fuels, as smelting did, amalgamation depended on the availability of mercury. Nearly all quicksilver used in colonial Spanish American silver mining came from either Huancavelica (Peru) or Almadén (Spain), with occasional supplements from Idria (Slovenia). Whereas both smelting and amalgamation were used widely in Mexico, Andean mines relied on amalgamation.

Urbanization and environmental change have worked in tandem over the course of Mexican history. Hinterland production, the establishment of market economies, and the intensive transformation of nature have fueled urban growth. The concentration of capital and expertise in cities has, in turn, enabled urban elites to rework the urban environment by creating industrial centers, executing technical-heavy infrastructure, building new subdivisions, and regulating hygiene. From the beaches of Cancún and the air and water pollution of Tijuana’s industrial parks to the prolific silver mines of Zacatecas and the henequen monoculture surrounding Mérida, Yucatán, rapid urban growth and profound changes to the environment within and outside cities have depended on and intersected with each other.
