Loving v. Virginia in the context of "Equal Protection Clause"

The Fourteenth Amendment (Amendment XIV) to the United States Constitution was adopted on July 9, 1868, as one of the Reconstruction Amendments. Considered one of the most consequential amendments, it addresses citizenship rights and equal protection under the law at all levels of government. The Fourteenth Amendment was a response to issues affecting freed slaves following the American Civil War, and its enactment was bitterly contested. States of the defeated Confederacy were required to ratify it to regain representation in Congress. The amendment, particularly its first section, is one of the most litigated parts of the Constitution, forming the basis for landmark Supreme Court decisions, such as Brown v. Board of Education (1954; prohibiting racial segregation in public schools), Loving v. Virginia (1967; ending interracial marriage bans), Roe v. Wade (1973; recognizing federal right to abortion until overturned in 2022), Bush v. Gore (2000; settling 2000 presidential election), Obergefell v. Hodges (2015; extending right to marry to same-sex couples), and Students for Fair Admissions v. Harvard (2023; prohibiting affirmative action in most college admissions).

The amendment's first section includes the Citizenship Clause, Privileges or Immunities Clause, Due Process Clause, and Equal Protection Clause. The Citizenship Clause broadly defines citizenship, superseding the Supreme Court's decision in Dred Scott v. Sandford (1857), which held that Americans descended from African slaves could not become American citizens. The Privileges or Immunities Clause was interpreted in the Slaughter-House Cases (1873) as preventing states from impeding federal rights, such as the freedom of movement. The Due Process Clause builds on the Fifth Amendment to prohibit all levels of government from depriving people of life, liberty, or property without substantive and procedural due process. Additionally, the Due Process Clause supports the incorporation doctrine, by which portions of the Bill of Rights have been applied to the states. The Equal Protection Clause requires each state to provide equal protection under the law to all people, including non-citizens, within its jurisdiction.

The legal recognition of same-sex marriage in the United States expanded from one state in 2004 (Massachusetts) to all 50 states in 2015 through various court rulings, state legislation, and direct popular vote. States have separate marriage laws, which must adhere to rulings by the Supreme Court of the United States that recognize marriage as a fundamental right guaranteed by both the Due Process Clause and the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution, as first established in the 1967 landmark civil rights case of Loving v. Virginia. Same-sex marriages are also licensed in and recognized by Washington, D.C. and all U.S. territories except for American Samoa, but not in some Native American tribal nations.

Civil rights campaigning in support of marriage without distinction as to sex or sexual orientation began in the 1970s. In 1972, the later-overturned Baker v. Nelson saw the Supreme Court of the United States decline to become involved. The issue became prominent from around 1993, when the Supreme Court of Hawaii ruled in Baehr v. Lewin that it was unconstitutional under the Constitution of Hawaii for the state to abridge marriage on the basis of sex. That ruling led to federal and state actions to explicitly abridge marriage on the basis of sex in order to prevent the marriages of same-sex couples from being recognized by law, the most prominent of which was the 1996 federal Defense of Marriage Act (DOMA). In 2003, the Massachusetts Supreme Judicial Court ruled in Goodridge v. Department of Public Health that it was unconstitutional under the Constitution of Massachusetts for the state to abridge marriage on the basis of sex. From 2004 through to 2015, as the tide of public opinion continued to move towards support of same-sex marriage, various state court rulings, state legislation, direct popular votes (referendums and initiatives), and federal court rulings established same-sex marriage in thirty-six of the fifty states.

In the United States, many U.S. states historically had anti-miscegenation laws which prohibited interracial marriage and, in some states, interracial sexual relations. Some of these laws predated the establishment of the United States, and some dated to the later 17th or early 18th century, a century or more after the complete racialization of slavery. Nine states never enacted anti-miscegenation laws, and 25 states had repealed their laws by 1967. In that year, the U.S. Supreme Court ruled in Loving v. Virginia that such laws are unconstitutional under the Fourteenth Amendment to the U.S. Constitution.

The term miscegenation was first used in 1863, during the American Civil War, by journalists to discredit the abolitionist movement by stirring up debate over the prospect of interracial marriage after the abolition of slavery.

Anti-miscegenation laws are laws that enforce racial segregation at the level of marriage and intimate relationships by criminalizing interracial marriage, sometimes also criminalizing sex between members of different races.

In the United States, interracial marriage, cohabitation and sex have been termed "miscegenation" since the term was coined in 1863. Contemporary usage of the term is infrequent, except in reference to historical laws which banned the practice. Anti-miscegenation laws were first introduced in North America by the governments of several of the Thirteen Colonies from the late seventeenth century onward, and subsequently, they were introduced by the governments of many U.S. states and U.S. territories and they remained in force in many US states until 1967. After the Second World War, an increasing number of states repealed their anti-miscegenation laws. In 1967, in the landmark case Loving v. Virginia, the remaining anti-miscegenation laws were ruled unconstitutional by the U.S. Supreme Court under Chief Justice Earl Warren.

Interracial marriage has been legal throughout the United States since at least the 1967 U.S. Supreme Court (Warren Court) decision Loving v. Virginia (1967) that held that anti-miscegenation laws were unconstitutional via the 14th Amendment adopted in 1868. Chief Justice Earl Warren wrote in the court 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." Interracial marriages have been formally protected by federal statute through the Respect for Marriage Act since 2022.

Historical opposition to interracial marriage was frequently based on religious principles. Many Southern evangelical Christians saw racial segregation, including in marriage, as something divinely instituted from God. They held that legal recognition of interracial couples would violate biblical teaching and hence their religious liberty. Roman Catholic theology, on the other hand, articulated strong opposition to any state-sanctioned segregation on the grounds that segregation violated human dignity. Since Loving, states have repealed their defunct bans, the last of which was Alabama in a 2000 referendum.
