Casta in the context of "Sacatra"

A caste is a fixed social group into which an individual is born within a particular system of social stratification: a caste system. Within such a system, individuals are expected to marry exclusively within the same caste (endogamy), follow lifestyles often linked to a particular occupation, hold a ritual status observed within a hierarchy, and interact with others based on cultural notions of exclusion, with certain castes considered as either more pure or more polluted than others. The term "caste" is also applied to morphological groupings in eusocial insects such as ants, bees, and termites.

The paradigmatic ethnographic example of caste is the division of India's Hindu society into rigid social groups. Its roots lie in South Asia's ancient history and it still exists; however, the economic significance of the caste system in India seems to be declining as a result of urbanisation and affirmative action programs. A subject of much scholarship by sociologists and anthropologists, the Hindu caste system is sometimes used as an analogical basis for the study of caste-like social divisions existing outside Hinduism and India. In colonial Spanish America, mixed-race castas were a category within the Hispanic sector but the social order was otherwise fluid.

Mestizo is a term primarily used to denote people of mixed Spanish and Indigenous ancestry in the former Spanish Empire. In certain regions such as Latin America, it may also refer to people who are culturally European, even though their ancestors were Indigenous Americans. The term was used as an ethno-racial exonym for mixed-race castas that evolved during the Spanish Empire. It was a formal label for individuals in official documents, such as censuses, parish registers, Inquisition trials, and others. Priests and royal officials might have classified persons as mestizos, but individuals also used the term in self-identification. With the Bourbon reforms and the independence of the Americas, the caste system disappeared and terms like "mestizo" fell in popularity.

The noun mestizaje, derived from the adjective mestizo, is a term for racial mixing that did not come into usage until the 20th century; it was not a colonial-era term. In the modern era, mestizaje is used by scholars such as Gloria Anzaldúa as a synonym for miscegenation, with positive connotations.

In the colonial societies of the Americas and Australia, a quadroon (/kwɑːˈdruːn/ kwah-DROON) or quarteron (quarter-caste in the United Kingdom) was a person with one-quarter African or Aboriginal ancestry, and three-quarters European ancestry. Similar classifications were octoroon for one-eighth black and quintroon for one-sixteenth black.

Governments of the time sometimes incorporated the terms in law, defining rights and restrictions. The use of such terminology is a characteristic of hypodescent, which is the practice within a society of assigning children of mixed unions to the ethnic group which the dominant group perceives as being subordinate. The racial designations refer specifically to the number of full-blooded African ancestors or equivalent, emphasizing the quantitative least, with quadroon signifying that a person has one-quarter black ancestry.

Juan Patricio Morlete Ruiz (San Miguel de Allende, 1713–1770, Mexico City) was an 18th-century Mexican painter, a mestizo according to the system of racial classification. He is most well known for his casta paintings.

Born in 1713 in San Miguel de Allende, he was a contemporary of Miguel Cabrera. Both artists were important to Casta painting and are accredited with many iconic elements of Casta painting that influenced the genre for decades after them. Like many artists in Colonial New Spain, he was a member of painting academy that was established in the mid-eighteenth century. This status gave Morlete a place among the Spanish elite in Mexico. It is evident from documents at the time that both the Viceroy Carlos Francisco De Croix and Viceroy Antonio María de Bucareli y Ursúa commissioned work from him.

Various types of visual arts developed in the geographical area now known as Mexico. The development of these arts roughly follows the history of Mexico, divided into the prehispanic Mesoamerican era, the colonial period, with the period after Mexican War of Independence, the development Mexican national identity through art in the nineteenth century, and the florescence of modern Mexican art after the Mexican Revolution (1910–1920).

Mesoamerican art is that produced in an area that encompasses much of what is now central and southern Mexico, before the Spanish conquest of the Aztec Empire for a period of about 3,000 years from Mexican Art can be bright and colourful this is called encopended. During this time, all influences on art production were indigenous, with art heavily tied to religion and the ruling class. There was little to no real distinction among art, architecture, and writing. The Spanish conquest led to 300 years of Spanish colonial rule, and art production remained tied to religion—most art was associated with the construction and decoration of churches, but secular art expanded in the eighteenth century, particularly casta paintings, portraiture, and history painting. Almost all art produced was in the European tradition, with late colonial-era artists trained at the Academy of San Carlos, but indigenous elements remained, beginning a continuous balancing act between European and indigenous traditions.
