New Spain, officially the Viceroyalty of New Spain (Spanish: Virreinato de Nueva España [birejˈnato ðe ˈnweβa esˈpaɲa]; Nahuatl languages: Yankwik Kaxtillan Birreiyotl), originally the Kingdom of New Spain, was an integral territorial entity of the Spanish Empire, established by Habsburg Spain. It was one of several domains established during the Spanish conquest of the Americas, and had its capital in Mexico City. Its jurisdiction comprised a large area of the southern and western portions of North America, mainly what became Mexico and the Southwestern United States, but also California, Florida and Louisiana; Central America (as part of Mexico); the Caribbean like Hispaniola and Martinique, and northern parts of South America, even Colombia; several Pacific archipelagos, including the Philippines and Guam. Additional Asian colonies included "Spanish Formosa", on the island of Taiwan.
After the 1521 Spanish conquest of the Aztec Empire, conqueror Hernán Cortés named the territory New Spain, and established the new capital, Mexico City, on the site of Tenochtitlan, the capital of the Aztec Empire. Central Mexico became the base of expeditions of exploration and conquest, expanding the territory claimed by the Spanish Empire. With the political and economic importance of the conquest, the crown asserted direct control over the densely populated realm. The crown established New Spain as a viceroyalty in 1535, appointing as viceroy Antonio de Mendoza, an aristocrat loyal to the monarch rather than the conqueror Cortés. New Spain was the first of the viceroyalties that Spain created, the second being Peru in 1542, following the Spanish conquest of the Inca Empire. Both New Spain and Peru had dense indigenous populations at conquest as a source of labor and material wealth in the form of vast silver deposits, discovered and exploited beginning in the mid-1600s.
New Spain developed strong regional divisions based on local climate, topography, distance from the capital and the Gulf Coast port of Veracruz, size and complexity of indigenous populations, and the presence or absence of mineral resources. Central and southern Mexico had dense indigenous populations, each with complex social, political, and economic organization, but no large-scale deposits of silver to draw Spanish settlers. By contrast, the northern area of Mexico was arid and mountainous, a region of nomadic and semi-nomadic indigenous populations, which do not easily support human settlement. In the 1540s, the discovery of silver in Zacatecas attracted Spanish mining entrepreneurs and workers, to exploit the mines, as well as crown officials to ensure the crown received its share of revenue. Silver mining became integral not only to the development of New Spain, but also to the enrichment of the Spanish crown, which marked a transformation in the global economy. New Spain's port of Acapulco became the New World terminus of the transpacific trade with the Philippines via the Manila galleon. New Spain became a vital link between Spain's New World empire and its East Indies empire.
From the beginning of the 19th century, the kingdom fell into crisis, aggravated by the 1808 Napoleonic invasion of Iberia and the forced abdication of the Bourbon monarch, Charles IV. This resulted in a political crisis in New Spain and much of the Spanish Empire in 1808, which ended with the government of Viceroy José de Iturrigaray. Conspiracies of American-born Spaniards sought to take power, leading to the Mexican War of Independence, 1810–1821. At its conclusion in 1821, the viceroyalty was dissolved and the Mexican Empire was established. Former royalist military officer turned insurgent for independence Agustín de Iturbide would be crowned as emperor.
The Crown and the Viceroyalty of New Spain
The Kingdom of New Spain was established on 18 August 1521, following the Spanish conquest of the Aztec Empire, as a New World kingdom ruled by the Crown of Castile. The initial funds for exploration came from Queen Isabella. Although New Spain was a dependency of Castile, it (Mexico) was a kingdom and not a colony, subject to the presiding monarch on the Iberian Peninsula.
The monarch had sweeping power in the overseas territories, with not just sovereignty over the realm but also property rights. All power over the state came from the monarch. The crown had sweeping powers over the Catholic Church in its overseas territories, and via the Patronato real, a grant by the papacy to the crown to oversee the Church in all aspects save doctrine. The Viceroyalty of New Spain was created by royal decree on 12 October 1535, in the Kingdom of New Spain with a viceroy appointed as the king's "deputy" or substitute. This was the first New World viceroyalty and one of only two that the Spanish Empire administered in the continent until the 18th-century Bourbon Reforms.

Territorial extent of the overseas Spanish Empire
At its greatest extent, the Spanish crown claimed on the mainland of the Americas much of North America south of Canada, that is: all of modern Mexico and Central America except Panama; most of the United States west of the Mississippi River, plus the Floridas. The Spanish West Indies, settled prior to the conquest of the Aztec Empire, also came under New Spain's jurisdiction: Cuba, Hispaniola, Puerto Rico, Jamaica, the Cayman Islands, Trinidad, Martinica and the Bay Islands. New Spain also claimed jurisdiction over the overseas territories of the Spanish East Indies in Asia and Oceania: the Philippine Islands, the Mariana Islands, the Caroline Islands, parts of Taiwan, and parts of the Moluccas. Although asserting sovereignty over this vast realm, it did not effectively control large swaths. Other European powers, including England, France, and the Netherlands established colonies in territories Spain claimed.
Much of what was called in the United States the "Spanish borderlands" is territory that attracted few Spanish settlers, with less dense indigenous populations and apparently lacking in mineral wealth. Huge deposits of gold in California were discovered immediately after it was incorporated into the U.S. following the Mexican–American War (1846–1848). The northern region of New Spain in the colonial era was considered marginal to Spanish interests compared to the most densely populated and lucrative areas of central Mexico. To shore up its claims in North America in the eighteenth century as other powers encroached on its claims, the crown sent expeditions to the Pacific Northwest, which explored and claimed the coast of British Columbia and Alaska.
Religious missions and fortified presidios were established to shore up Spanish control on the ground. On the mainland, the administrative units included Las Californias, that is, the Baja California peninsula, still part of Mexico and divided into Baja California and Baja California Sur; Alta California (modern Arizona, California, Nevada, Utah, western Colorado, and southern Wyoming); (from the 1760s) Louisiana (including the western Mississippi River basin and the Missouri River basin); Nueva Extremadura (the modern states of Coahuila and Texas); and Santa Fe de Nuevo México (parts of Texas and New Mexico).

Government
Viceroyalty
The Viceroyalty was administered by a viceroy residing in Mexico City and appointed by the Spanish monarch, who had administrative oversight of all of these regions, although most matters were handled by the local governmental bodies, which ruled the various regions of the viceroyalty. First among these were the audiencias, which were primarily superior tribunals, but which also had administrative and legislative functions. Each of these was responsible to the Viceroy of New Spain in administrative matters (though not in judicial ones), but they also answered directly to the Council of the Indies.
Captaincies general and governorates
The Captaincy Generals were the second-level administrative divisions and these were relatively autonomous from the viceroyalty. The viceroy was captain-general of those provinces that remained directly under his command. Santo Domingo (1535); Philippines (1565); Puerto Rico (1580); Cuba (1608); Guatemala (1609); Yucatán (1617); Commandancy General of the Provincias Internas (1776) (analogous to a dependent captaincy general). Two governorates, third-level administrative divisions, were established, the Governorate of Spanish Florida (Spanish: La Florida) and the Governorate of Spanish Louisiana (Spanish: Luisiana).
Cartography
Spanish officials in New Spain used cartography as a tool to assert political authority. Maps served to define territorial claims and impose order on Indigenous communities, as mapmaking became closely tied to imperial governance. This shaped how land was conceptualized and controlled across the colony.

High courts
The high courts, or audiencias, were established in major areas of Spanish settlement. In New Spain the high court was established in 1527, prior to the establishment of the viceroyalty. The First Audiencia was headed by Hernán Cortés's rival Nuño de Guzmán, who used the court to deprive Cortés of power and property. The crown dissolved the First Audiencia and established the Second Audiencia.
The audiencias of New Spain were Santo Domingo (1511, effective 1526, predated the Viceroyalty); Mexico (1527, predated the Viceroyalty); Panama (1st one, 1538–1543); Guatemala (1543); Guadalajara (1548); Manila (1583).
Audiencia districts further incorporated the older, smaller divisions known as governorates (gobernaciones, roughly equivalent to provinces), which had been originally established by conquistador-governors known as adelantados. Provinces which were under military threat were grouped into captaincies general, such as the Captaincies General of the Philippines (established 1574) and Guatemala (established in 1609), which were joint military and political commands with a certain level of autonomy. The viceroy was captain-general of those provinces that remained directly under his command.

Local-level administration
At the local level there were over two hundred districts, in both indigenous and Spanish areas, which were headed by either a corregidor (also known as an alcalde mayor) or a cabildo (town council), both of which had judicial and administrative powers. In the late 18th century the Bourbon dynasty began phasing out the corregidores and introduced intendants, whose broad fiscal powers cut into the authority of the viceroys, governors and cabildos. Despite their late creation, these intendancies so affected the formation of regional identity that they became the basis for the nations of Central America and the first Mexican states after independence.
Intendancies of the 1780s
As part of the sweeping eighteenth-century administrative and economic changes known as the Bourbon Reforms, the Spanish crown created new administrative units called intendancies, to strengthen central control over the viceroyalty. Some measures aimed to break the power of local elites in order to improve the economy of the empire. Reforms included the improvement of public participation in communal affairs, distribution of undeveloped lands to the indigenous and Spaniards, ending the corrupt practices of local crown officials, encouraging trade and mining, and establishing a system of territorial division similar to the model created by the government of France, already adopted in Spain.
The establishment of intendancies was strongly resisted by the viceroyalties and general captaincies similar to the opposition in the Iberian Peninsula when the reform was adopted. Royal audiencias and ecclesiastical hierarchs opposed the reform for its intervention in economic issues, for its centralist politics, and the forced ceding of many of their functions to the intendants. In New Spain, these units generally corresponded to the regions or provinces that had developed earlier in the center, South, and North.

Many of the intendancy boundaries became Mexican state boundaries after independence. The intendancies were created between 1764 and 1789, with the greatest number in the mainland in 1786: 1764 La Habana (later subdivided); 1766 Nueva Orleans; 1784 Puerto Rico; 1786 México, Veracruz, Puebla de Los Ángeles, Guadalajara, Guanajuato, Zacatecas, San Luis Potosí, Sonora, Durango, Oaxaca, Guatemala, San Salvador, Comayagua, León, Santiago de Cuba, Puerto Príncipe; 1789 Mérida.
Social Hierarchy
The social structure of New Spain was organized around a hierarchy that placed peninsulares and criollos at the top, while Indigenous peoples, Africans, and mixed-race groups faced restrictions on mobility and rights. Over time, there were demographic shifts and economic changes that challenged the hierarchy and created new opportunities for social advancement among certain groups.
Legal Culture
By the eighteenth century, New Spain had developed a distinctive legal culture that blended Spanish judicial traditions with local practices and regional autonomy. Courts relied on a wide array of legal documents and negotiations that allowed Indigenous communities and settlers to assert rights and/or resolve conflicts.
History of New Spain
The history of mainland New Spain spans three hundred years from the Spanish conquest of the Aztec Empire (1519–1521) to the collapse of Spanish rule in the Mexican War of Independence (1810–1821).
Beginning with the Spanish conquest of the Aztec Empire in 1521 by Hernán Cortés, Spanish rule was established, leading to the creation of governing bodies like the Council of the Indies and the Audiencia to maintain control. It involved the forced conversion of indigenous populations to Catholicism and the blending of Spanish and indigenous cultures in both the mainland and the Caribbean islands of Martinica and Hispaniola.
During the 17th and 18th centuries Spanish settlers founded major cities such as Mexico City, Puebla, and Guadalajara, turning New Spain into a vital part of the Spanish Empire. The discovery of silver in Zacatecas and Guanajuato significantly boosted the economy, leading to conflicts like the Chichimeca War. Missions and presidios were established in northern frontiers, aiding in the expansion and control of territories that later became part of the southwestern United States. The 18th century saw the implementation of the Bourbon Reforms, which aimed to modernize and strengthen the colonial administration and economy. These reforms included the creation of intendancies, increased military presence, and the centralization of royal authority. The expulsion of the Jesuits and the establishment of economic societies, were part of the efforts to enhance efficiency and revenue for the crown.
The decline of New Spain culminated in the early 19th century with the Mexican War of Independence. Following Miguel Hidalgo y Costilla's 1810 Cry of Dolores, the insurgent army waged an eleven-year war against Spanish rule. The eventual alliance between royalist military officer Agustín de Iturbide and insurgent leader Vicente Guerrero led to the successful campaign for independence. In 1821, New Spain officially became the independent nation of Mexico, ending three centuries of Spanish colonial rule. During a period that was especially important to the social development of America, the movement to expel the Moors and Jews from Spain stirred up a previously dormant aspect of Spanish social structure.
Economy
During the era of the conquest, to pay off the debts incurred by the conquistadors and their companies, the new Spanish governors awarded their men grants of native tribute and labor, known as encomiendas. The encomienda became one of the defining institutions of early Spanish rule in New Spain, thus formalizing the right of colonists to Indigenous labor. While some supporters justified the system as a means of "protecting" native communities, in practice, it often intensified the already present exploitation. New Spain, these grants were modeled after the tribute and corvee labor that the Mexica rulers had demanded from native communities. This system came to signify the oppression and exploitation of natives, although its originators may not have set out with such intent. In short order, the upper echelons of patrons and priests in the society lived off the work of the lower classes. Due to some horrifying instances of abuse against the indigenous peoples, Bishop Bartolomé de las Casas suggested bringing black slaves to replace them. Fray Bartolomé later repented when he saw the even worse treatment given to the black slaves.
In colonial Mexico, Encomenderos de Negros were specialized middlemen during the first half of the seventeenth century. While encomendero (alternatively, encomenderos de indios) generally refers to men granted the labor and tribute of a particular indigenous group in the immediate post-conquest era, encomenderos de negros were Portuguese slave dealers who were permitted to operate in Mexico for the slave trade.
In Peru, the other discovery that perpetuated the system of forced labor, the mit'a, was the enormously rich single silver mine discovered at Potosí, but in New Spain, labor recruitment differed significantly. Except silver mines worked in the Aztec period at Taxco, southwest of Tenochtitlan, Mexico's mining region was outside the area of dense indigenous settlement. Labor for the mines in the north of Mexico had a workforce of black slave labor and indigenous wage labor, not draft labor. Indigenous who were drawn to the mining areas were from different regions of the center of Mexico, with a few from the north itself. With such diversity, they did not have a common ethnic identity or language and rapidly assimilated into Hispanic culture. Although mining was difficult and dangerous, the wages were good, which is what drew the indigenous labor.
The Viceroyalty of New Spain was the principal source of income for Spain in the eighteenth century, with the revival of mining under the Bourbon Reforms. Important mining centers like Zacatecas, Guanajuato, San Luis Potosí and Hidalgo had been established in the sixteenth century and suffered a decline for a variety of reasons in the seventeenth century, but silver mining in Mexico out-performed all other Spanish overseas territories in revenues for the royal coffers.
The fast red dye cochineal was an important export in areas such as central Mexico and Oaxaca in terms of revenues to the crown and stimulation of the internal market of New Spain. Cacao and indigo were also important exports for the New Spain, but was used through rather the vice royalties rather than contact with European countries due to piracy, and smuggling. The indigo industry in particular also helped to temporarily unite communities throughout the Kingdom of Guatemala due to the smuggling.
There were two major ports in New Spain, Veracruz the viceroyalty's principal port on the Atlantic, and Acapulco on the Pacific, the terminus of the Manila galleon. In the Philippines Manila near the South China Sea was the main port. The ports were fundamental for overseas trade, stretching a trade route from Asia, through the Manila galleon to the Spanish mainland.
These were ships that made voyages from the Philippines to Mexico, whose goods were then transported overland from Acapulco to Veracruz and later reshipped from Veracruz to Cádiz in Spain. So then, the ships that set sail from Veracruz were generally loaded with merchandise from the East Indies originating from the commercial centers of the Philippines, plus the precious metals and natural resources of Mexico, Central America, and the Caribbean. During the 16th century, Spain held the equivalent of US$1.5 trillion (1990 terms) in gold and silver received from New Spain.
However, these resources did not translate into development for the Metropolis (mother country) due to the Spanish Roman Catholic Monarchy's frequent preoccupation with European wars (enormous amounts of this wealth were spent hiring mercenaries to fight the Protestant Reformation), as well as the incessant decrease in overseas transportation caused by assaults from companies of British buccaneers, Dutch corsairs and pirates of various origins. These companies were initially financed by, at first, by the Amsterdam stock market, the first in history and whose origin is owed precisely to the need for funds to finance pirate expeditions, as later by the London market. The above is what some authors call the "historical process of the transfer of wealth from the south to the north".
Regions of mainland New Spain
In the colonial period, basic patterns of regional development emerged and strengthened. European settlement and institutional life was built in the Mesoamerican heartland of the Aztec Empire in Central Mexico. The South (Oaxaca, Michoacán, Yucatán, and Central America) was a region of dense indigenous settlement of Mesoamerica, but without exploitable resources of interest to Europeans, the area attracted few Europeans, while the indigenous presence remained strong.
The North was outside the area of complex indigenous populations, inhabited primarily by nomadic and hostile northern indigenous groups. With the discovery of silver in the north, the Spanish sought to conquer or pacify those peoples in order to exploit the mines and develop enterprises to supply them. Nonetheless, much of northern New Spain had sparse indigenous population and attracted few Europeans. The Spanish crown and later the Republic of Mexico did not effectively exert sovereignty over the region, leaving it vulnerable to the expansionism of the United States in the nineteenth century.
Regional characteristics of colonial Mexico have been the focus of considerable study. For those based in the vice-regal capital of Mexico City, everywhere else were the "provinces". Even in the modern era, "Mexico" for many refers solely to Mexico City, with the pejorative view that anywhere outside the capital is a hopeless backwater. "Fuera de México, todo es Cuauhtitlán" ("outside of Mexico City, it's all Podunk"), that is, poor, marginal, and backward, in short, the periphery.
The picture is far more complex, however; while the capital is enormously important as the center of institutional, economic, and social power, the provinces played a significant role in colonial Mexico. Regions (provinces) developed and thrived to the extent that they became sites of economic production and tied into networks of trade. "Spanish society in the Indies was import-export oriented at the very base and in every aspect," and the development of many regional economies was typically centered on support of that export sector.
Central region
Mexico City, capital of the viceroyalty
Mexico City was the center of the Central region, and the hub of New Spain. The development of Mexico City itself was vitally important to the development of New Spain as a whole. It was the seat of the Viceroyalty of New Spain, the Archdiocese of the Catholic Church, the Holy Office of the Inquisition, the merchants' guild (consulado), and home of the most elite families in the Kingdom of New Spain. Mexico City was the single most populous city, not just in New Spain, but for many years the entire Western Hemisphere, with a high concentration of mixed-race castas.
Veracruz to Mexico City
Significant regional development grew along the main transportation route from the capital east to the port of Veracruz. Alexander von Humboldt called this area Mesa de Anahuac, which can be defined as the adjacent valleys of Puebla, Mexico, and Toluca, enclosed by high mountains, along with their connections to the Gulf Coast port of Veracruz and the Pacific port of Acapulco, where over half the population of New Spain lived. These valleys were linked trunk lines, or main routes, facilitating the movement of vital goods and people to get to key areas.
Even in the relatively richly endowed region of Mexico, the difficulty of transit of people and goods in the absence of rivers and level terrain remained a major challenge to the economy of New Spain. This challenge persisted during the post-independence years until the late nineteenth-century construction of railroads. In the colonial era and up until the railroads were built in key areas in post-independence in the late nineteenth century, mule trains were the main mode of transporting goods. Pack mules were used because unpaved roads, mountainous terrain, and seasonal flooding could not generally accommodate carts.
In the late eighteenth century, the crown devoted some resources to study and remedy the poor roads. The Camino Real (royal road) between the port of Veracruz and the capital had some short sections paved and bridges constructed. The construction was done despite protests from some indigenous settlements when the infrastructure improvements, which sometimes included rerouting the road through communal lands. The Spanish crown finally decided that road improvement was in the interests of the state for military purposes, as well as for fostering commerce, agriculture, and industry, but the lack of state involvement in the development of physical infrastructure was to have lasting effects, constraining development until the late nineteenth century. Despite the road improvements, transit was still difficult, particularly for heavy military equipment.
Although the crown had ambitious plans for both the Toluca and Veracruz portions of the king's highway, improvements were limited to a localized network. Even where infrastructure was improved, transit on the Veracruz-Puebla main road had other obstacles, with wolves attacking mule trains, killing animals, and rendering some sacks of foodstuffs unsellable because they were smeared with blood. The north-south Acapulco route remained a mule track through mountainous terrain.
Veracruz, port city and province
Veracruz was the first Spanish settlement founded in what became New Spain, and it endured as the only viable Gulf Coast port, the gateway for Spain to New Spain. The difficult topography around the port affected local development and New Spain as a whole. Going from the port to the central plateau entailed a daunting 2000 meter climb from the narrow tropical coastal plain in just over a hundred kilometers. The narrow, slippery road in the mountain mists was treacherous for mule trains, and in some cases mules were hoisted by ropes. Many tumbled with their cargo to their deaths.
