Ancient bones discovered in northern Chile are providing fresh insight into how communities under the Inca Empire treated people with disabilities living with severe illness. New research suggests that individuals with long-term physical conditions were not abandoned or pushed aside. Instead, evidence indicates that they were supported by the people around them and remained part of daily community life.
The findings come from a study led by bioarchaeologist Catalina Morales and published in the International Journal of Paleopathology. Researchers examined the remains of a woman who lived during the Inca expansion into northern Chile, roughly between 1400 and 1550 A.D. Careful examination of her skeleton shows signs of a serious chronic disease that likely limited her ability to move and perform many common tasks.
Despite the challenges associated with the illness, the woman lived into older adulthood and was buried in a typical community cemetery. The details of her burial and the condition of her bones suggest that she received care and assistance for many years.
A skeleton that tells the story of long-term disease
Scientists determined that the skeleton belonged to a woman who died at about 45 years of age or older. The burial site dates to the Late Horizon period, when the Inca Empire extended its reach across large parts of the Andes, including northern Chile.
Researchers first estimated the woman’s age and biological sex through visual analysis of the bones. They then carried out a paleopathological examination to identify possible diseases.
The results revealed extensive joint damage throughout her body. Signs of inflammation and degeneration appeared in the spine, sacrum, hands, knees, and feet. Based on these changes, researchers believe the woman most likely suffered from spondyloarthritis — a chronic inflammatory disease that affects the spine and other joints.
This condition can cause severe pain, stiffness, and reduced mobility. In advanced stages, it may make simple daily activities difficult. The widespread damage seen in the skeleton indicates that the disease progressed over many years.
Burial evidence suggests community support
Living with such a condition would have posed major challenges in an agricultural society where physical labor was essential. Daily tasks such as farming, gathering food, and carrying water required strength and mobility.
Yet the woman survived for decades with the illness. Researchers say reaching that age with such physical limitations likely required consistent help from others within the community.
Additional clues come from the way she was buried. The woman was placed in a local cemetery alongside other community members and was accompanied by typical burial offerings, including pottery, gourds, baskets, and spindle whorls. These items match objects found in nearby graves from the same period.
There was no sign of social exclusion or special treatment in the burial arrangement. Instead, the evidence suggests she remained fully integrated within her society despite her physical condition.
Insights into care and compassion in the Inca world
The cemetery is located in Chile’s Copiapo Valley, an area once home to the Copiapo culture before the arrival of Inca rule. During the Late Horizon period, the Inca state expanded into the region and built public structures for political and ceremonial activities, linking local communities to the growing empire.
Even during this time of political change, the new findings indicate that local groups maintained strong traditions of mutual support.
Caring for someone with a chronic disease would have required time, food, and protection from the community. Researchers say the woman’s survival suggests that such support systems were in place.
The case also provides early evidence that spondyloarthritis existed in South America before Spanish colonization. Beyond medical insights, the discovery offers a rare view into the human side of ancient societies.
According to researchers, the remains of Inca people with disabilities highlight the role of empathy and shared responsibility in community life. The woman’s story suggests that people in the Inca world valued care and inclusion, even when individuals faced serious physical challenges.
