Parts of Mexico have been able to retain traditions in El Dia de los Muertos - Day of the Dead. I have been privileged in the past to participate in this holy holiday time in Oaxaca City - one of the southern states with large indiginous populations.

It is a family holiday that is very poignant, where families celebrate their deceased loved ones by building altars of remembrance decorated with pictures of the deceased, crosses, flowers, mezcal/tequila, food, etc.
The holidays start on the 31st up to the 2nd. Families clean and decorate gravesites in a similar fashion and stay up all night reminiscing and celebrating the memories of loved ones. One night is dedicated to infants.
Stores and houses are decorated for the holiday. There are impromptu plays in the street. Small groups of musicians play songs and encourage merriment and dance. There are bands playing in the town square in the evening.
It might sound macabre but it really isn't. Death is grieved, mocked, and laughed at. It is quite a refreshing change to our cultural relationship to death.
May justice and peace return to Oaxaca soon.
