Loving Day is an annual celebration held on June 12, the anniversary of the 1967 United States Supreme Court decision Loving v. Virginia that struck down all anti-miscegenation laws remaining in sixteen U.S. states. In the United States, anti-miscegenation laws were U.S. state laws banning mixed-race marriages. The Warren Court ruled unanimously in 1967 that these state laws were unconstitutional. Chief Justice Earl Warren wrote in the court majority opinion that "the freedom to marry, or not marry, a person of another race resides with the individual, and cannot be infringed by the State."
