The eight indigenous tribes of Mindoro have known no other home since prehistory, although their ancestors probably migrated from Indonesia. (The seventh-largest island in the Philippines, Mindoro is part of the MIMAROPA Region and is divided into two provinces, Oriental Mindoro and Occidental Mindoro.) The tribes, which are referred to by the general term "Mangyan," comprise the Alangan, Bangon, Buhid, Hanunoo, Iraya, Ratagnon, Tadyawan, and Tawbuid. The Mangyan population in the Philippines is over 100,000, and the great majority have grown roots in Mindoro.
Ratagnons, found in the southern tip of Occidental Mindoro, are also known as Datagnons and Latagnons. It is believed that they are not original settlers of Mindoro since their language is more similar to Cuyonon, a language in Palawan.
Ratagnons still wear their traditional clothing: a wraparound skirt for women and g-string for men. They are said to have rattan coils that are dyed red around their waistlines, which distinguishes them from other groups.
