When was el dia de los muertos invented?

El Día de los Muertos, or the Day of the Dead, has roots that trace back to ancient Mesoamerican cultures, particularly the Aztecs, who honored their deceased ancestors. While the tradition has evolved over centuries, it was officially recognized and celebrated in its current form around the 20th century, particularly after the 1930s when it began to gain popularity as a national holiday in Mexico. The holiday combines indigenous rituals with Spanish Catholic influences, creating a unique celebration that honors the dead.
