When Richard and Mildred Loving had the audacity to marry, Virginia law officers jailed them. The state’s highest court later agreed it was right to outlaw their marriage because he was white and she was black. Now, a half century after the Lovings won a landmark U.S. Supreme Court ruling that legalized interracial marriage nationwide, the couple has been honored with a historical marker outside the old Virginia Supreme Court building where they suffered a legal defeat. “We honor their courage to stand up for the right to love unconditionally, their strength to endure the struggle against all odds and their tenacity to prove that loving is really what it’s all about,” Claire Guthrie Gastanaga, executive director of the American Civil Liberties Union of Virginia, said Monday during a dedication ceremony.
