Analysis of colonization processes that occurred before the availability of written records has traditionally relied on methods from fields such as archaeology and linguistics. However, the rapid development of DNA testing has introduced a novel approach to investigating these historical processes. In this study, we utilize genetictesting to examine the colonization of Västerbotten, a region in northern Sweden. Although detailed written records exist from the 18th century onward through parishregisters, the region’s earlier history remains only partially understood.
This study employs genetic analysis to explore the demographic and migratory patterns of Västerbotten’s early inhabitants. The primary objective was to tracethe progression of colonization, including the demographics, migration routes, andancestry of early settlers. By analyzing haplogroup patterns, we uncovered insightsinto the paternal lines that have shaped the region’s genetic landscape over the past two millennia, providing valuable implications for understanding the colonizationprocess.
Furthermore, this study underscores the significant potential of genetic genealogyas a tool for reconstructing complex historical demographic processes. Our findings demonstrate how analyzing paternal lineages that contribute to the genetic makeup of the Västerbotten population can reveal clues about regional colonization dynam-ics. This work illustrates the broader applicability of genetic analysis in deepeningour understanding of historical events, not only in this region but also in similar contexts worldwide.
