Despite Indonesia's constitutional ban on slavery, an ancient caste system on Sumba Island continues to trap thousands in inherited servitude, where slaves (ata) work without pay, face physical abuse, and cannot escape due to economic dependency and deeply ingrained cultural traditions that persist despite modern legal prohibitions.

Hidden slaves of Sumba: Inside Indonesia's ancient caste system today
Added:[music] >> They work from dawn to dusk without pay.
They are passed on in marriage.
Some are even beaten [music] and raped by their masters.
Yet most are resigned to their fate.
Canisius [music] Kenyali Hambarita is a 34-year-old slave known locally as an ata.
For him, this lifetime of servitude is [music] an inescapable reality.
Slavery has been [music] illegal in what is now Indonesia for more than 160 years.
But it survives within the rigid caste system on [music] the island of Sumba.
Canisius lives in a village that draws tourists looking for a hidden tropical paradise.
He lives there with his master, 31-year-old [music] Umbu Ana Rara.
Master and slave share a towering traditional thatched [music] house.
They sleep on mats on the floor chewing betel nuts in the morning heat.
Canisius is permitted to earn a little money driving [music] a motorcycle taxi.
Despite his absolute lack of freedom, he accepts [music] his inherited position without resentment.
His master, [music] Umbu Ana Rara, is part of the maramba, or noble class.
He allows his ata some small modern freedoms while still maintaining absolute [music] authority over his life and choices.
>> [music] >> Because they live under the same roof, Umbu insists their bond goes deeper than forced labor.
>> [music] >> But other slaves tell a much darker story when their masters are out of earshot.
One Arta from a nearby village recounted being beaten and covered in water as a child if he failed to finish his chores.
He was forced to work in the fields right after school.
>> [music] >> Today, he tells his own children he never wants them to suffer the same abuse.
Eight out of 10 people in Sumba's population of 685,000 are Christian.
However, an older belief system called Marapu has deep [music] roots here.
It blends animism and ancestor worship.
57-year-old Protestant pastor Marlin Lomi explains how this ancient religion strictly divides society. [music] >> [music] >> Legend says the Maramba nobles acquired their Artas when they first arrived in Sumba.
The island [music] is isolated 2,000 km east of Jakarta.
This geographical distance [music] has helped preserve these ancestral structures.
Indonesia banned slavery under its 1945 constitution.
Yet on Sumba, an estimated several thousand slaves remain trapped in bondage.
The exact number is hard to verify.
What is known is that Maramba masters have long underpinned their domination with physical violence.
Pastor Lomi notes that this systemic abuse is deeply normalized, particularly when it comes to women.
>> [music] [music] >> Rights activists say this abuse often goes unpunished because victims are terrified to testify.
One 18-year-old slave finally went to the police in 2024.
She reported being [music] raped by her master and his son since she was just 13.
Two years later, the investigation remains stalled.
The caste system is so deeply rooted that holding the noble class accountable is incredibly difficult.
Gideon Mbiliyora is a former regent of East Sumba, and he actually owns two attas himself.
Even as a member of the elite, he acknowledges the slow shift in perspective regarding these deeply ingrained traditions.
Rights groups like Amnesty International and Human Rights Watch are urging the national government to enforce the constitutional ban on slavery.
But officials argue for a more gradual approach.
>> Indonesia >> [music] [music] >> Some nobles are already trying to improve the lot of the atas from the inside.
54-year-old Norlina Ramboe Jola Kalunga is a maramba noblewoman and a pastor.
She wants to see slaves emancipated starting with a shift in how the next [music] generation is raised.
>> [music] >> Still, [music] she cannot officially free her own inherited slaves without going against strict local [music] custom.
Other noble women have advocated for emancipation [music] and sent their atas to school.
Some even allow them to leave.
But without money or land, escaping is nearly impossible.
Even those who try to break away often find [music] themselves shackled to their old masters.
The man who was [music] beaten as a boy managed to send his children to university.
He did this by selling his own livestock.
Yet, he still farms on his master's land. [music] When his master calls, he must answer.
Today, he dreams that his children will finally [music] be free from the maramba believing that education is their only true path to freedom.
