Cultural attributes of a group, known as the Urnfield Culture, expanded from Central Europe to Northeastern Iberia during the Final Bronze Age (FBA), from ~1300 to ~850 cal BCE. Various hypotheses on the group’s emergence exist, but cremations hinder DNA preservation. Here, we present genome-wide data from 24 inhumed individuals from a collective burial mound at the site of Los Castellets II (Spain), where inhumations and cremations co-occurred during the FBA, and one Early Iron Age (EIA) individual from Los Piojos (Spain). The results show that two source populations are required to explain the ancestry at Los Castellets II: one enriched in steppe-related ancestry and distantly related to Central European BA populations, and a second source similar to local Southeastern Iberian BA. Additionally, two-thirds of the individuals from the same collective tumulus were closely biologically related from 1st to >6th degree, with a man having the highest number of genetic relatives. We detected signs of inbreeding within the family group, all together suggesting the tumulus was used as a family mausoleum. info:eu-repo/grantAgreement/ES/AEI/RYC2022-035700-I info:eu-repo/grantAgreement/EC/H2020/771234/EU/Human health and migration in prehistory/PALEoRIDER This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 771234-PALEoRIDER info:eu-repo/grantAgreement/ES/MINECOPID2022-140671NB-100 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Rohrlach, Adam B.
