Basques formed a minority ethnic group whose diaspora had a significant impact on the history of colonial Latin America. Basques from the four Spanish or peninsular Basque territories—the Lordship of Vizcaya, the provinces of Álava and Guipúzcoa, and the Kingdom of Navarra—migrated to the New World in significant numbers; the French Basques were also prominent in the Atlantic, particularly in the Newfoundland fisheries.
The population density of the Basque Atlantic valleys, which was the highest of any region in Spain, was an important factor that encouraged emigration. And, in response to demographic pressure, in the second half of the 15th century most villages and towns adopted an impartible inheritance system that compelled non-inheriting offspring to seek their fortunes outside the country. Castile was the immediate choice for the Basque émigré, but after 1492 America gradually became an attractive destination. Outside their home country, their unique language and sense of collective nobility (hidalguía universal) were to become two outstanding features of Basque cultural identity.
The Basques’ share of total Spanish migration to the New World increased significantly in the second half of the 17th century. By the 18th century they were one of the largest and most influential peninsular regional groups in America. The typical Basque émigré was a young, single man aged between fifteen and thirty. In the New World they left their mark in economic activities that their countrymen had developed in their homeland for centuries: trade, navigation, shipbuilding, and mining. Furthermore, Basques’ collective nobility and limpieza de sangre (blood purity) facilitated their access to important official positions.
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.
On August 13, 1521, the Spanish conquistadors and their native allies seized Tenochtitlan, the capital of the Aztec empire. The Spaniards succeeded because they had forged alliances with the Tlaxcalans and other indigenous self-governing communities (altepetl) to fight the Aztecs. After the conquest these communities continued their traditions, and the Spaniards largely replaced Aztec leadership with their own. In addition, the friars and the secular church converted the natives to an extent, and together with the crown they foiled the conquistadors’ attempts to become liege lords with jurisdiction. The process culminated in the New Laws of 1542, which curbed the encomienda, a grant to Spaniards that comprised several Indian towns paying tribute. A society of social bodies evolved, composed of municipal councils, lay brotherhoods of churches, and others, complete with their own laws and jurisdictions. Then a series of silver strikes beginning at Zacatecas in 1546 drew settlers into the Bajío north of the former Aztec and Tarascan empires. The local natives resisted initially, and when peace came, they and the settlers created a dynamic early capitalist economy that invigorated other regions. The frontier expanded when animal herds moved further north beyond the mines, and the zone of Spanish influence grew to the south as well.
In 1540 Spanish conquistadors and their indigenous allies began occupying the northwestern Yucatan Peninsula, and they took Tiho/Mérida in 1542. The Yucatan, the Bajío, and the other regions that composed colonial Mexico successively integrated into a global commercial network spanning Europe, Africa, and Asia. The crown and the merchant guild (consulado) in Seville sought to capture the burgeoning Atlantic commerce within the fleet shuttling between Seville/Cadiz and Veracruz and restrict the silver flowing from Acapulco to Asia via the Philippines. Yet market forces defied most of the rules they put in place. Merchants from Asia settled in Manila; Peruvians docked in Acapulco; and the Dutch, French, and English competed with fleet merchants or operated contraband trade from the Caribbean islands to New Spain. In the 18th century, the crown loosened trade regulations within the empire and continue curbing the autonomies of social bodies. A series of investigations (visitas) shook New Spain, and more compliant viceroys and officials appeared, while the friars lost over one hundred parishes (doctrinas) during the mid-century. The king expelled the Jesuits in 1767; registered ships sailing individually replaced the fleet in 1778; and in 1786 José de Gálvez introduced the intendants in New Spain. As the empire transitioned toward a territorial state, Napoleon imprisoned the Spanish king (1808). In 1810 Miguel Hidalgo and a popular following unleashed the War of Independence. As the conflict unfolded, the legitimacy of the old order crumbled, and the empire dissolved in 1821.
