The Dinagyang is a religious and cultural festival in Iloilo City, Philippines held on the fourth Sunday of January, or right after the Sinulog In Cebu and the Ati-Atihan in Aklan. It is held both to honor the Santo Niño and to celebrate the arrival on Panay of Malay settlers and the subsequent selling of the island to them by the Atis.
The Dinagyang is divided into three Major events: Ati-Ati Street Dancing, Kasadyahan Street Dancing and Miss Dinagyang.
Today, the main part of the festival consists of a number of “tribes”, called “tribus”, who are supposed to be Ati tribe members dancing in celebration. It should be noted that no actual Ati are involved nor do they benefit in any way from this event. There are a number of requirements, including that the performers must paint their skin brown and that only indigenous materials can be used for the costumes. All dances are performed to drum music. Many tribes are organized by the local high schools. Some tribes receive a subsidiary from the organizers and recruit private sponsors, with the best tribes receiving the most. The current Ati population of Iloilo is not involved with any of the tribes nor are they involved in the festival in any other way.
