1924: How Eugenics Wrote America's Immigration & Anti-Marriage Laws
In 1924 eugenic science became federal and state law. Congress passed the Immigration Act with Harry Laughlin as its expert eugenics agent and rigged IQ data behind national-origins quotas that later helped trap refugees fleeing Hitler. Virginia's Racial Integrity Act, enforced by registrar Walter Plecker with a one-drop rule, tried to erase Native Virginians, and its marriage ban stood until 1967.

Still debated
Historians debate how decisive eugenic testimony was in 1924, since nativism and labor concerns also drove restriction. Estimates of lives lost to refugee quotas are uncertain, and the long-term effect of Plecker's records on tribal recognition remains contested.
