What landmark court case in 1967 affected laws regarding interracial relationships?

The correct answer is Loving v. Virginia. This landmark Supreme Court case, decided in 1967, had a profound impact on laws regarding interracial relationships by declaring state bans on interracial marriage unconstitutional. The case involved Richard and Mildred Loving, an interracial couple who were sentenced to a year in prison in Virginia for marrying, as their union violated the state's anti-miscegenation law. The court's ruling emphasized the right to marry as a fundamental freedom and addressed the discriminatory motivations behind such laws, ultimately leading to the invalidation of similar laws across the United States.

In contrast, the other cases mentioned focus on different critical issues. Brown v. Board of Education addressed the legality of racial segregation in public schools, Roe v. Wade concerned women's rights to make decisions about their own bodies, specifically regarding abortion, and Miranda v. Arizona focused on the rights of arrested individuals to be informed of their rights before police questioning. Each of these cases plays a significant role in civil rights and personal liberties, but none directly relate to the legality of interracial marriages like Loving v. Virginia does.
