Overview
- Recent mid-2026 reporting documented that a caste-based system on Sumba keeps some people as atas—born into lifelong servitude passed down as inherited status.
- Enslaved people work without pay, can be transferred as property, and face documented physical and sexual violence with few prosecutions.
- A high-profile 2024 case of a woman abused from age 13 prompted a police probe that rights monitors say remained unfinished two years later, highlighting slow investigations and impunity.
- Indonesia’s constitution and penal code formally ban slavery but also recognize customary law, and national officials have publicly favored gradual social change over forcible intervention.
- Local responses are uneven: estimates range from about 1,700 in East Sumba to thousands overall, and NGOs, churches and some nobles have freed or educated some atas even as the wider system endures.
