When did eugenics become popular?

Eugenics became popular in the late 19th and early 20th centuries, particularly in the United States and Europe. The movement gained momentum after the publication of Francis Galton's work in the 1880s, advocating for the improvement of human populations through controlled breeding. It reached its peak in the 1920s and 1930s, influencing policies on Immigration, marriage, and sterilization. The rise of eugenics declined significantly after World War II, due in part to its association with the atrocities committed by the Nazi regime.
