In Hispanic America, criollo is a term used originally to describe people of full Spanish descent born in the viceroyalties. In different Latin American countries, the word has come to have different meanings, mostly referring to the local-born majority.

The Bourbon Reforms consisted of political and economic changes promulgated by the Spanish Crown under various kings of the House of Bourbon, since 1700, mainly in the 18th century. The beginning of the new Crown's power with clear lines of authority to officials contrasted to the complex system of government that evolved under the Habsburg monarchs. For example, the crown pursued state predominance over the Catholic Church, pushed economic reforms, and placed power solely into the hands of civil officials.
