Opinion of the Court
has made assumptions defined by the world and time of which it is a part. This was evident in Baker v. Nelson, 409 U. S. 810, a one-line summary decision issued in 1972, holding the exclusion of same-sex couples from marriage did not present a substantial federal question.
Still, there are other, more instructive precedents. This Court’s cases have expressed constitutional principles of broader reach. In defining the right to marry these cases have identified essential attributes of that right based in history, tradition, and other constitutional liberties inherent in this intimate bond. See, e. g., Lawrence, 539 U. S., at 574; Turner, supra, at 95; Zablocki, supra, at 384; Loving, supra, at 12; Griswold, supra, at 486. And in assessing whether the force and rationale of its cases apply to same-sex couples, the Court must respect the basic reasons why the right to marry has been long protected. See, e. g., Eisenstadt, supra, at 453–454; Poe, supra, at 542–553 (Harlan, J., dissenting).
This analysis compels the conclusion that same-sex couples may exercise the right to marry. The four principles and traditions to be discussed demonstrate that the reasons marriage is fundamental under the Constitution apply with equal force to same-sex couples.
A first premise of the Court’s relevant precedents is that the right to personal choice regarding marriage is inherent in the concept of individual autonomy. This abiding connection between marriage and liberty is why Loving invalidated interracial marriage bans under the Due Process Clause. See 388 U. S., at 12; see also Zablocki, supra, at 384 (observing Loving held “the right to marry is of fundamental importance for all individuals”). Like choices concerning contraception, family relationships, procreation, and childrearing, all of which are protected by the Constitution, decisions concerning marriage are among the most intimate that an individual can make. See Lawrence, supra, at 574. Indeed, the Court has noted it would
