Fifty years ago, the U.S. Supreme Court struck down laws against interracial marriage in Loving v. Virginia. But Richard and Mildred Loving were not the first American couple to love across race boundaries. The history of what we would now consider interracial relationships in America extends back to the first European explorations of the continent. In this episode of the Modern Law Library, the ABA Journal's Lee Rawles speaks with Sheryll Cashin, a professor of law at Georgetown University and author of Loving: Interracial Intimacy in America and the Threat to White Supremacy. Cashin discusses how the concept of race was introduced in America; how the doctrine of white supremacy was used as a method to divide slaves and free blacks from indentured servants; how flimsy the rationale for racial classification was; and the stories of some men and women who ignored those barriers and formed relationships anyway. She also shares her thoughts on how a younger generation's "cultural dexterity" could help battle the forces of racism and white supremacy.
