Casta

Casta (, ) is a Spanish and Portuguese term used in 17th and 18th centuries mainly in Spanish America to describe as a whole the mixed-race people which appeared in the post-Conquest period. A parallel system of categorization based on the degree of acculturation to Hispanic culture, which distinguished between gente de razón (Hispanics) and gente sin razón (non-acculturated natives), concurrently existed and worked together with the idea of casta.

The system of castas, or genizaros was inspired by the assumption that the character and quality of people varied according to their birth, color, race and origin of ethnic types. The system of castas was more than socio-racial classification. It impacted every aspect of life, including economics and taxation. Both the Spanish colonial state and the Church expected more tax and tribute payments from those of lower socio-racial categories.
