Exploring the African Lineage of Irish and Italian Identities: Historical Connections and Modern Perspectives

This study examines the intersection of claims about African lineage with Irish and Italian identities, integrating genetic, sociohistorical, and cultural evidence within a single analytical framework. This study poses three research questions: (1) What do population-genetic studies show about African admixture in Italy and Ireland, and how do those signals vary across regions and time? (2) How do socio-historical processes—migration, empire, trade, religion, and racialization— shape identity claims about (or against) African ancestry? (3) Can biomedical data on hemoglobinopathies (sickle-cell disease and thalassemia) and malaria selection be coherently interpreted alongside population genetics? Methodologically, I synthesized peer-reviewed population genetics and ancient DNA studies with historical scholarship and diaspora/postcolonial theory [1-3]. The key findings are: (a) measurable North African-linked ancestry is concentrated in Southern Italy and Sicily and reflects long-range Mediterranean connectivity; (b) at a population level, Ireland shows minimal sub-Saharan African admixture, though modern migration has increased the number of Irish residents of African descent and the local clinical relevance of SCD; and (c) biomedical patterns (SCD and β‑thalassemia) track malaria ecology and mobility rather than any simple, homogeneous 'African descent' for whole national populations. The study advocates for the careful use of genetic evidence, alignment with sociohistorical interpretation, and the avoidance of essentialist claims.
