Answer:
Colonization.
Explanation:
The classification of social class sections in New Spain was a result of the colonial expansion by the mother nation. New Spain, also known as Mexico, would become a Spanish colony and a new home for Spanish people.
The five classes of the New Spain society are- Peninsulares, Creoles, Mestizos, Native American Indians, Enslaved persons. This classification was done based on the nature of the 'origin' of the person, the more Spanish blood you are, the higher class you belong to. This categorization was a result of the colonization of the American continent by the Spanish.
