Legalizing same-sex marriage in the United States reached a historic milestone in June 2015 when the U.S. Supreme Court ruled in Obergefell vs. Hodges that denying marriage rights to same-sex couples was unconstitutional. With this landmark 5–4 decision, all state-level bans on same-sex marriage were invalidated, and nationwide recognition and issuance of same-sex marriage licenses became mandatory. While many states had already legalized same-sex marriage prior to the ruling, others had constitutional amendments or laws prohibiting it. The Supreme Court’s decision marked a significant victory for the LGBTQ+ community, unifying marriage laws across the country. The following is a state-by-state overview of each state’s legal stance on same-sex marriage leading up to and following the 2015 ruling.
