In the centuries following the Spanish conquests of Mexico and Peru most Native Americans were at least nominally converted to Catholicism. The blending of native and Catholic beliefs was a complicated process, and it followed different courses in different areas. In general, the Aztecs made Catholicism the core of a new religion that also incorporated native beliefs, while the Mayas retained native beliefs as the core of their religion and added Catholic elements. The Incan case, perhaps the most complicated of the three, represented an intricate blending of native and Catholic beliefs, aided by certain parallels between the two.

In essence, the Spanish conquest of 1519-1521 destroyed the core of Aztec religion—the cult of warfare and human sacrifice. The Aztecs were no longer able to feed the sun, yet the universe survived, and Huitzilopochtli was discredited. Aztec religion had lost its focus by 1531, when, according to Catholic tradition, the Virgin of Guadalupe appeared to an Aztec man named Juan Diego. Devotion to the Virgin spread rapidly, and within six years 9 million Indians had been baptized as Catholics in central Mexico. Worship of some Aztec gods and goddesses, most notably ancient agricultural deities, persisted. These deities were blended with Catholic saints in the new religion.

In contrast to the Aztec case, when the Spanish began their conquest of the Maya area, Maya religion was already fragmented. The great religious and political centers of the Classic period had been abandoned more than 600 years earlier, and even the Post-Classic centers were in decline. The religion practiced in hamlets and villages emphasized ancient agricultural deities—such as the rain gods (Chacs)—who proved to endure. Maya folk religion still centers on these agricultural deities, and Catholic and native beliefs are more distinct from each other than they are among the descendants of the Aztecs.

The Incas, like the Aztecs, had a central imperial cult: the worship of the royal mummies. However, the Incan imperial cult, like the Mesoamerican worship of agricultural deities, was an expression of the ancient and widespread religious tradition of ancestor worship. The Spanish destroyed the royal Incan mummies and their cult, but not the underlying tradition of ancestor worship. During the 16th and 17th centuries, Incan and Catholic beliefs were blended, revealing parallels between the two traditions. For example, both the Incas and their Spanish conquerors made special commemoration of the dead during the month of November and had penitential rites that involved confessing sins to priests.

In recent decades evangelical Protestantism, especially in the form of Pentecostalism, has been spreading rapidly among Latin American Indians. At the same time, community-based social action movements are a growing force within Latin American Catholicism. Whether these are short- or long-term trends, and what effects they will have on native religious traditions, are unresolved questions.
