The sites sampled — Viminacium (Rit, Pirivoj, Više Grobalja, Pećine, Stari Kostolac) and Timacum Minus (Slog) — lay along the middle Danube in the province historically known as Moesia Superior. Archaeological data indicates Viminacium grew from a 1st-century CE legionary base into a bustling urban and funerary landscape; Timacum Minus functioned as a smaller military and civic node to the east.
Material remains—fortifications, bath complexes, tombstones, and imported ceramics—bear witness to long-distance connections across the Roman Empire. The 64 ancient genomes analyzed come from cemetery contexts and settlement deposits spanning 1–538 CE, providing a regionally concentrated window into population composition during the Imperial and Late Antique periods.
Limited evidence suggests that much of the population shows continuity with local Balkan Iron Age lineages, overlaid by gene-flow signals consistent with Mediterranean and eastern Mediterranean connections typical of Roman frontier towns. Archaeological stratigraphy and grave goods corroborate episodes of immigration and mobility: soldier burial types, non-local pottery, and osteological markers of diverse diets and activities. While the dataset is substantial for a single region, caution is warranted when interpreting rarer genetic lineages present at low counts.
