Who was the one to legalize marriage in the entire United States between men and women of different races?

The landmark Supreme Court case Loving v. Virginia in 1967 legalized interracial marriage across the United States. The ruling struck down laws prohibiting interracial marriage, declaring them unconstitutional. Richard and Mildred Loving, the couple at the center of the case, were instrumental in challenging these discriminatory laws. Their victory marked a significant step towards civil rights and equality in marriage.
