Summary Answer
Same-sex marriage became legal nationwide in the United States on June 26, 2015, when the U.S. Supreme Court issued its decision in Obergefell v. Hodges. The ruling required all states to license and recognize marriages between two people of the same sex, establishing a constitutional right to marriage regardless of gender. This decision built on earlier rulings, such as United States v. Windsor (2013), and followed decades of state-level legalization and court actions.
Key Supreme Court Cases That Made Gay Marriage Legal
The path to nationwide marriage equality turned on two landmark Supreme Court rulings. Together, these cases define the current legal status of same-sex marriage in the United States.
United States v. Windsor (2013)
In United States v. Windsor, the Court struck down Section 3 of the Defense of Marriage Act (DOMA), which had defined marriage federally as a union between one man and one woman. The decision required the federal government to recognize valid same-sex marriages performed under state law. While Windsor did not legalize same-sex marriage nationwide, it extended federal benefits and set the doctrinal foundation for Obergefell v. Hodges.
Obergefell v. Hodges (2015)
Obergefell v. Hodges consolidated multiple cases challenging state bans on same-sex marriage. In a 5–4 decision, the Court held that the Fourteenth Amendment’s guarantees of due process and equal protection require states to license marriages between two people of the same sex and to recognize such marriages performed lawfully elsewhere. The ruling made same-sex marriage legal in all 50 states and created a uniform national standard.
Timeline of State Legalization Before Obergefell
Long before Obergefell, many states had already legalized same-sex marriage through legislation, court decisions, or voter action. By June 2015, 37 states and the District of Columbia recognized same-sex marriage. The following table highlights key milestones leading to nationwide legalization.
| Date or Period | Event | Why It Matters |
|---|---|---|
| May 17, 2004 | Massachusetts becomes the first state to legalize same-sex marriage (Goodridge v. Dept. of Public Health). | First statewide recognition of same-sex marriage in the U.S. |
| 2008–2014 | Connecticut, Iowa, Vermont, New Hampshire, New York, Washington, Maryland, Maine, New Jersey, Rhode Island, Delaware, Minnesota, Hawaii, Illinois, Nevada, Oregon, Pennsylvania, and others legalize same-sex marriage via court rulings, legislation, or ballot measures. | Demonstrates growing state-level acceptance and legal recognition prior to federal ruling. |
| June 26, 2013 | U.S. Supreme Court decides United States v. Windsor. | Strikes down DOMA Section 3; federal recognition of state-legal same-sex marriages begins. |
| June 26, 2015 | U.S. Supreme Court decides Obergefell v. Hodges. | Establishes a constitutional right to same-sex marriage nationwide. |
Immediate Legal and Social Effects of Obergefell
Within days of the Obergefell decision, same-sex couples in states that had previously banned marriage began obtaining licenses and marrying. States that had not recognized same-sex marriage had to update policies, issue guidance to county clerks, and train officials on compliance. Major legal questions about religious exemptions and implementation persisted, but the constitutional right to marry was firmly established.
Ongoing Protections and Current Status
As of today, same-sex marriage remains legal in all 50 states and in U.S. territories under the Obergefell precedent. The decision is widely cited in related rulings involving parental rights, adoption, immigration, and workplace benefits. While debates about religious liberty and nondiscrimination continue, Obergefell is treated as settled law and is not under active reconsideration by the Supreme Court.
Lasting Effects on Policy and Society
Obergefell reshaped family law, tax policy, health care, and workplace protections. Federal agencies updated forms and eligibility criteria to include same-sex spouses. Public opinion shifted rapidly in favor of marriage equality, and the decision is frequently referenced in broader LGBTQ+ rights litigation. For many couples, Obergefell simplified matters related to property, inheritance, taxes, and parental recognition that had been uncertain before legalization.
