The Philippines has produced nine cardinals. The population of Catholics in the Philippines constitutes the country's largest religious denomination, as well as one of the largest Catholic populations among countries of the world. The Catholic faith was introduced to the Philippines by Spanish colonists in the sixteenth century. Some 400 years later, in 1960, Rufino J. Santos, the Archbishop of Manila, became the first Filipino cardinal. Since then, a total of nine Filipinos have been raised to the rank of cardinal.
