What does Eugenics have to do with race

Eugenics is a pseudo-scientific theory that aims to improve the genetic quality of a human population through selective breeding and sterilization of individuals who are deemed to have inferior traits. In the past, eugenics has often been used as a justification for racist ideologies and policies, as proponents of eugenics have targeted certain racial and ethnic groups for forced sterilization or other forms of population control. This has resulted in widespread discrimination and harm against marginalized communities based on their perceived genetic and racial characteristics.
