#2 - Mexico - 98,820,000 Catholics
Catholicism was brought to Mexico by Spanish conquistadors and missionaries in the early 16th century, with a priest arriving at the Peninsula of Yucatán in 1519 as a member of Hernán Cortés' expedition, in what is now known as Veracruz ("the True Cross"). A few years later, in 1524, twelve Franciscan friars also arrived in Mexico, being later known as "Los Doce" ("The twelve", in a clear reference to Christ's own twelve apostles). The Dominican order got to Mexican land in 1526, followed by the Augustinians in 1533.
