Overview
R1a-Y2613 is one of the principal subbranches of R1a-Y33 and plays a crucial role in the paternal history of eastern European populations. The lineage emerged during the Bronze Age among communities inhabiting regions between the Vistula basin, the Baltic hinterland and the upper Dnieper territories. Archaeological sites connected to this period show fortified settlements, metalworking workshops and regional trade networks that linked Y33 and Y2613 ancestors to wider Balto-Slavic cultural transformations. During the Iron Age, Y2613 lineages became involved in the formation of early Baltic and proto Slavic cultures. Its presence in hillfort complexes, forest zone communities and mixed agricultural populations reflects broad social integration. With the rise of Slavic tribal confederations in the early medieval period, Y2613 experienced significant demographic expansion. It formed multiple founder clusters that spread throughout Poland, Belarus and western Russia. The lineage is especially tied to the ancestry of groups inhabiting the Pripet marsh region, which is widely considered an important homeland for early Slavs. Today, Y2613 remains a key lineage for understanding internal variation within the Balto-Slavic paternal structure. Its wide presence highlights deep demographic continuity in eastern Europe.
