When discussing New Spain society, reference is often made to a supposedly rigid and perfectly organized “caste system.” However, the historical reality was much more complex. During the 16th and 17th centuries, the Viceroyalty of New Spain underwent a profound process of biological, cultural, and social miscegenation that defied any attempt at simple classification.
This article analyzes whether the so-called castes really existed as a formal system, how social classifications arose, and what role they played in the viceregal order.
The starting point: the two republics
Following the military campaign of Cortés and his indigenous allies, the Mesoamerican territories became part of the Catholic monarchy, under the viceregal administration organized by the Crown of Castile.
In the 16th century, the legal structure distinguished mainly between two social groups: the republic of indigenous peoples and the republic of Spaniards. This division served administrative, fiscal, and religious purposes. However, everyday reality soon showed that society was much more diverse.
Miscegenation as a social reality
From the early decades of the viceroyalty, mestizo and Afro-descendant populations emerged, along with diverse family combinations resulting from contact between indigenous peoples, Europeans, and Africans brought over as slaves.
The growth of these groups was not marginal. In cities, mines, estates, and ports, daily coexistence generated changing identities that did not always fit into simple legal categories.
Was there a formal caste system?
There was no single code establishing a closed and universal “caste system.” Classifications such as mestizo, mulatto, castizo, or zambo appeared in notarial documents, censuses, and parish records, but their use was flexible and often inconsistent.
Rather than a rigid system, what existed was a set of social and administrative practices that attempted to bring order to a society in transition. Factors such as occupation, reputation, wealth, and family networks could have a greater influence than strict ethnic origin.

Caste paintings: late representation
The so-called caste paintings emerged mainly during the 18th century, in an urban and literate context, especially in Mexico City. They were produced by New Spanish painters—some of whom were well known, such as Miguel Cabrera, José de Ibarra, and Juan Rodríguez Juárez—who worked for the Creole elite and, in many cases, for officials or collectors linked to the viceregal administration.
These pictorial series were not simply genre portraits. They generally consisted of 16 scenes arranged in sequence, depicting different family combinations between Spaniards, indigenous people, and people of African descent. Each scene featured a couple with their son or daughter, accompanied by an inscription naming the “mixture.”
Why were they painted? In part, they responded to an enlightened curiosity to classify and organize the social diversity of the viceroyalty. They also served as objects of display for educated audiences, both inside and outside New Spain, who sought to understand—and at the same time hierarchize—the social complexity of the Americas. Rather than faithfully describing everyday reality, they offered an idealized, orderly, and deeply hierarchical representation.
Several contemporary researchers have reevaluated their interpretation. Historians such as Ilona Katzew, María Concepción García Sáiz, and Pilar Gonzalbo Aizpuru have shown that these paintings do not prove the existence of a rigid legal system, but rather reflect social concerns, discourses on honor, purity of blood, and status, as well as tensions inherent in a highly stratified society.
Far from being an objective record, caste paintings should be understood as cultural constructs that attempted to capture in images a social reality that was much more fluid than their labels suggested.
Classification and social control
Even though there was no rigid legal system, the classifications did have consequences. They determined access to positions, social mobility, tax payments, and certain legal restrictions.
The viceregal order sought to maintain hierarchies, but it was also permeable. There were individuals and families who improved their social position through legal strategies, marriages, military service, or the accumulation of wealth.
Social inequality in New Spain was not simply an intellectual classification or a descriptive exercise typical of the Enlightenment mentality: it was a deeply hierarchical and often violent reality. Access to public office, religious orders, higher education, land ownership, or social prestige was conditioned by family origin, skin color, legitimacy of birth, and so-called “purity of blood.” Although there was no single legal caste code, in practice there were persistent racial prejudices that associated certain origins with moral inferiority or political incapacity. People of indigenous or African descent—and their descendants—faced higher tax burdens, social restrictions, and constant suspicion about their honor. The ideal of a harmonious order concealed tensions, exclusions, and everyday mechanisms of discrimination that structured social life in the viceroyalty.
Conclusion
Caste systems did not exist as a perfectly structured legal system from the beginning of the viceroyalty. What did exist was a constant process of social classification in a society marked by miscegenation and mobility.
Understanding this difference allows us to analyze New Spain with greater historical accuracy, avoiding simplifications and recognizing the complexity of its social fabric.
Frequently asked questions
Was there officially a caste system in New Spain?
There was no “caste system” codified as a single law that formally organized society. However, there was a deeply hierarchical social structure that distinguished between indigenous people, Spaniards, Africans, and people of mixed origin, with legal, fiscal, and social consequences.
This context was also influenced by the criteria of “cleanliness” or “purity of blood,” inherited from the peninsular tradition, which valued family origin and ancestry as key elements for accessing certain positions, honors, or spaces of prestige. Although they did not operate as a single, universal regulation, these criteria reinforced the inequality and social racism of the period.
What were caste paintings?
These were pictorial series produced in the 18th century depicting different family combinations between Spaniards, indigenous peoples, and Africans. Rather than reflecting an exact reality, they sought to show—and symbolically order—the social diversity of the viceroyalty for enlightened audiences, often within the Catholic monarchy.
Do caste paintings accurately reflect social reality?
Not entirely. They are a valuable source for understanding the mindset of the 18th century, but they do not represent an accurate census or a rigid system applied in everyday life. They functioned more as an idealized or didactic representation of social diversity.
Why is it important to study this topic today?
Because it allows us to understand how social hierarchies were constructed during the viceregal period and how certain ideas about origin, mixing, and social “quality” influenced Mexico’s subsequent history.
