When Gay Marriage Was Legalized in Each State

In a 5-4 decision, the U.S. Supreme Court legalized same-sex marriage in all 50 states on June 26, 2015. Not everyone was happy, however. As Roe v. Wade was overturned in 2022, fears were that the case that led to the legalization of gay marriage would be next.

As a result, steps were taken to protect same-sex and biracial marriages when President Joe Biden signed the Respect for Marriage Act into law on Dec. 13, 2022. Many states enacted laws much earlier than this. When was gay marriage legalized in the U.S. and around the world? The Netherlands was the first country to legalize same-sex marriages in 2001. Since then, 30 additional countries have legalized gay marriage.

Despite the U.S. Supreme Court decision and Biden's Respect for Marriage Act, not every state agrees. These states follow federal law, but attempts to pass state-level laws have failed. This article has information on the states that have and haven't legalized gay marriage on a state level.
