The Day of the Dead celebrations in Mexico developed from ancient traditions among its pre-Columbian cultures. Rituals celebrating the deaths of ancestors had been observed by these civilizations perhaps for as long as 2,500–3,000 years.
Day of the Dead (Spanish: Día de Muertos) is a Mexican holiday observed throughout Mexico and around the world in other cultures. The holiday focuses on gatherings of family and friends to pray for and remember friends and family members who have died.
