The article describes the significance of religion for the form and composition of Spanish-American cities. The cities were politically shaped by new government techniques and the exercise of royal rule, which were organized around elaborate ceremonial regimens centered on the figure of the Spanish king and Catholic religious rituals. The Catholic presence was also evident in the physical presence of numerous cathedrals, churches, monasteries, and chapels in the cities of the Spanish Empire. Participation in religious rituals and ceremonies was of great importance for the legitimacy of royal rule. The cities of Spanish America developed a new epistemology that connected them with new understandings of antiquity and granted them authority.

Cathedrals often favored the worship of saints associated with the monarchy, the origins of the city, or the founding of their cathedral chapter. The cult of patron saints was an important religious currency used by cities in competition for primacy and religious power among the cities in the empire. In Puebla de los Angeles, founded in 1531 in New Spain, the Archangel Michael became closely associated with the bishopric of Puebla a hundred years later, after the Archangel appeared to the Indian Diego Lázaro in a city under his jurisdiction in 1631. The decision of the Bishop of Puebla, Gutierrez Bernardo de Quiroz (1626-1638), to build a sanctuary to mark this miracle led to a lasting cult of the saint in Puebla.
