Well, here we must be cautious. First, let us remember that the word indigenous comes from the western point of view. In fact, people from distinct cultures, before
the colonization, did not call themselves indigenous. The term indigenous can be misleading,
because it puts many diverse cultures in the same category and a lot of them still
exist and thrive.
Día de los Muertos is a tradition originated in Mexico that now is shared along other
Latin-American countries. Each country observes different customs. The Mexican tradition
is a complex combination of indigenous Aztec and the Spanish Catholic traditions.
It has been inscribed, since 2008, on the Representative List of the Intangible Cultural Heritage of Humanity by UNESCO.
However, one of the main elements that Día de los Muertos carries from those so-called
indigenous origins is the belief that when someone dies, their spirits do not go to another
physical place like heaven or hell. The spiritual world is in this same world, but
experienced in a different dimension, a deeper one. The spiritual world is here, but
more connected to the entire universe, especially with nature. That belief was transformed
with time and now some people believe that during the night of the celebration, the
spirits will come to visit us.
