The celebration has been a Mexican tradition for over 400 years, starting in 1586. Many Mexican holidays include dramatizations of original events, a tradition which has its roots in the ritual of Bible plays used to teach religious doctrine to a largely illiterate population in 10th- and 11th-century Europe. The plays lost favor with the Church and were eventually banned as they became popular through the addition of folk music and other non-religious elements; they were reintroduced in the 16th century by two Spanish saints as the Christmas pageant — a new kind of religious ceremony to accompany the Christmas holiday.
