Answer:
United States v. Windsor legalized same-sex marriage in the United States.
Explanation:
Although the United States v. Windsor case in 2013, represents a landmark on civil rights, that set the focus on civil rights for married same-sex couples, and set a precedent for the later legalization of these unions, it did not legalize same-sex marriage in the United States.
It was the Obergefell v. Hodges case, in 2015, in which the Supreme Court ruled that the right to marry was a fundamental right that should be guaranteed for same sex couples, requiring all fifty states to perform and recognize same-sex marriage.
