When did the Roman Catholic religion start in Mexico?

Roman Catholicism in Mexico dates back to the 16th century, with the arrival of Spanish conquistadors and missionaries in the region. After the Spanish conquest of the Aztec Empire in 1521, the Catholic Church played a central role in the colonization and evangelization of Mexico. Catholic missionaries, such as Franciscan and Dominican friars, established missions and churches throughout the country, converting indigenous populations to Catholicism.

The Catholic Church maintained a dominant position in Mexico for several centuries, influencing the country's cultural, social, and political life. Additionally, significant religious institutions were built during the colonial period, contributing to Mexico's rich architectural and cultural heritage.
