Examining eugenics formation, rationale, various practices, and social impacts centered on the United Kingdom, the United States, and Germany, revealing the historical impact of science and social interactions and biologicalism on society. The author examines the trajectory of so-called scientificism, especially biologicalism, which has been increasingly strengthened since the advent of modern science through eugenics, or genetic politics. It shows that the history of biopolitics was penetrating Western modern history.
