(2) The history of marriage is one of both continuity and change. Changes, such as the decline of arranged marriages and the abandonment of the law of coverture, have worked deep transformations in the structure of marriage, affecting aspects of marriage once viewed as essential. These new insights have strengthened, not weakened, the institution. Changed understandings of marriage are characteristic of a Nation where new dimensions of freedom become apparent to new generations.
This dynamic can be seen in the Nation’s experience with gay and lesbian rights. Well into the 20th century, many States condemned same-sex intimacy as immoral, and homosexuality was treated as an illness. Later in the century, cultural and political developments allowed same-sex couples to lead more open and public lives. Extensive public and private dialogue followed, along with shifts in public attitudes. Questions about the legal treatment of gays and lesbians soon reached the courts, where they could be discussed in the formal discourse of the law. In 2003, this Court overruled its 1986 decision in Bowers v. Hardwick, 478 U. S. 186, which upheld a Georgia law that criminalized certain homosexual acts, concluding laws making same-sex intimacy a crime “demea[n] the lives of homosexual persons.” Lawrence v. Texas, 539 U. S. 558, 575. In 2012, the federal Defense of Marriage Act was also struck down. United States v. Windsor, 570 U. S. ___. Numerous same-sex marriage cases reaching the federal courts and state supreme courts have added to the dialogue. Pp. 6–10.
(b) The Fourteenth Amendment requires a State to license a marriage between two people of the same sex. Pp. 10–27.
(1) The fundamental liberties protected by the Fourteenth Amendment’s Due Process Clause extend to certain personal choices central to individual dignity and autonomy, including intimate choices defining personal identity and beliefs. See, e. g., Eisenstadt v. Baird, 405 U. S. 438, 453; Griswold v. Connecticut, 381 U. S. 479, 484–486. Courts must exercise reasoned judgment in identifying interests of the person so fundamental that the State must accord them its respect. History and tradition guide and discipline the inquiry but do not set its outer boundaries. When new insight reveals discord between the Constitution’s central protections and a received legal stricture, a claim to liberty must be addressed.
Applying these tenets, the Court has long held the right to marry is protected by the Constitution. For example, Loving v. Virginia, 388 U. S. 1, 12, invalidated bans on interracial unions, and Turner v. Safley, 482 U. S. 78, 95, held that prisoners could not be denied the right to marry. To be sure, these cases presumed a relationship in-
