Same-Sex Marriage, State by State

In 2015, the U.S. Supreme Court ruled all state bans on same-sex marriage unconstitutional, allowing gay and lesbian couples to marry nationwide.

Massachusetts became the first state to legalize same-sex marriage following a ruling by the state’s highest court in 2003.
