The history of the Catholic Church in Mexico can be divided into distinct periods, the basic division being between colonial Mexico, known as New Spain and the national period, from Mexican independence in 1821 until the current era.

The era of the military conquest in the early sixteenth century saw the Church's huge effort to evangelize the indigenous population of Mexico in what is termed "the spiritual conquest".
As the Spanish Empire expanded into new territories, the incorporation of the indigenous population was a priority for the crown.
The growth of the Spanish and mixed-race urban population of Mexico prompted the establishment of the episcopal hierarchy, under the patronage of the monarch and the creation of dioceses in Mexico.

In the national period, following independence in early nineteenth century, Mexico established a legal framework that continued the privileged status of the Catholic Church as the sole religion.
La Reforma of the late 1850s sparked an extended period of violent conflict between the conservative supporters of the old order and liberals who sought to displace and diminish the power of the Church.
The Mexican Revolution was won largely anticlerical Constitutionalists and the Church's role in Mexico was restricted constitutionally.

After a period of violent open conflict over religious matters, Church-State relations returned to a modus vivendi while the anticlerical constitutional framework remained in place.
Expansion of Catholic participation in the establishment of religious educational institutions and the creation of a conservative political party, the National Action Party with no direct ties to the Church was an important characteristic of the late twentieth century.
A new constitutional framework was created in 1992, which lifted many but not all restrictions on religious freedom and the Catholic Church in Mexico.
