Abstract
Abstract
The Medieval Ottonian dynasty had a lasting impact on European history. We obtained ancient genomic DNA from the purported remains of Otto I (912-973) and Heinrich (Henry) II (973-1024), the first and last emperors of this dynasty, preserved in the cathedrals of Magdeburg and Bamberg, respectively. Historical records attest that they were related as a great-uncle and a grandnephew via the paternal line. Whole-genome sequencing confirms such a relationship between the two individuals, as we identify a third-degree genetic relationship based on shared DNA segments and infer matching Y haplogroups. This genetic relatedness effectively identifies the remains of the two emperors. The authentication yields a valuable resource for refining and calibrating bio-archaeological methods. Because historical records provide the precise lifespans and dates of death of these individuals, their remains can serve as a ground truth for methods such as radiocarbon dating and age-at-death estimates. They can provide calibration data to improve our understanding of the radiocarbon reservoir effects of Medieval elites. As the Ottonian lineage was closely linked to the mating networks of elites across Europe, the genomes of the two emperors are valuable resources for identifying other potential elite burials.
