Originally, the Day of the Dead as such was not celebrated in northern Mexico, where it was unknown until the 20th century because its indigenous people had different traditions. The people and the church rejected it as a day related to syncretizing pagan elements with Catholic Christianity. They held the traditional 'All Saints' Day' in the same way as other Christians in the world. There was limited Mesoamerican influence in this region, and relatively few indigenous inhabitants from the regions of Southern Mexico, where the holiday was celebrated. In the early 21st century in northern Mexico, Día de Muertos is observed because the Mexican government made it a national holiday based on educational policies from the 1960s; it has introduced this holiday as a unifying national tradition based on indigenous traditions.[6][7][8]
The Mexican Day of the Dead celebration is similar to other culture's observances of a time to honor the dead. The Spanish tradition included festivals and parades, as well as gatherings of families at cemeteries to pray for their deceased loved ones at the end of the day.
