DNA Study Reveals Hereditary 'Sacrificial Caste' in Ancient Korea

Researchers analyzed 78 skeletons and found 11 first-degree and 23 second-degree relatives, pointing to a maternal kinship network in Silla burials.

  • On Wednesday, researchers published a study in Science Advances analyzing DNA from 78 skeletons in Gyeongsan, South Korea, confirming Silla Kingdom elites and sacrificed individuals practiced "consanguineous" marriage.
  • Excavated from the Imdang-Joyeong burial complex, the remains date to the Three Kingdoms period between the 4th and 6th centuries, when society practiced "sunjang" rituals honoring royalty.
  • Genomic data reconstructed 13 family trees, revealing entire households in Gyeongsan were sacrificed as "retainers" to honor Silla royalty about 1,500 years ago, according to the analysis.
  • Evidence suggests a "sacrificial caste" existed in Silla, with families inheriting roles to serve the elite across consecutive generations, according to researchers.
  • Jack Davey, director of the Early Korean Studies Center in Cambridge, Massachusetts, told Live Science the findings raise profound questions about institutionalized violence and social mobility in the 1,500-year-old kingdom.
