Casta

Casta (Spanish:) is a term which means "lineage" in Spanish and Portuguese and has historically been used as a racial and social identifier. From the outset, colonial Spanish America resulted in widespread intermarriage: unions of Spaniards (españoles), indigenous people (indios), and black Africans (negros). Basic mixed-race categories that appeared in official colonial documentation were mestizo, generally offspring of a Spaniard and an Indigenous person; and mulatto, offspring of a Spaniard and a black African.
A plethora of terms were used for people with mixed Spanish, Indigenous, and sub-Saharan African ancestry in 18th-century casta paintings, but they are not known to have been widely used officially or unofficially in the Spanish Empire.
