Timeline of same-sex marriage#1971

The summary table below lists in chronological order the sovereign states (United Nations member states plus Taiwan) that have legalized same-sex marriage. As of January 2025, 38 states have legalized same sex marriage.

Dates are when marriages between same-sex couples began to be officially certified. When distinguished, the initial date is the date of legalization in the first subnational jurisdiction (state, province or constituent country), and the second is the completion date for all jurisdictions, not counting external territories (or in the case of the US, sovereign tribal nations). A dash indicates that same-sex marriage is not (yet) legal in all jurisdictions. This is the case for the Kingdom of the Netherlands, where the constituent country Sint Maarten has not yet legalized, and for the Realm of New Zealand, where the constituent countries of Niue and the Cook Islands have not legalized.

{{Static row numbers}}

* State controls one or more territories where same-sex marriage is not performed or not recognized.

Cicero mentions the marriage (using the Latin verb for "to marry", i.e. nubere) of the son of Curio the Elder, but he does it in a metaphorical form to criticize his enemy Antonius. Cicero states thus that the younger Curio was "united in a stable and permanent marriage" to Antonius.Cicero Philippic 18 February, 2.45 See old translation at: http://old.perseus.tufts.edu/cgi-bin/ptext?doc=Perseus%3Atext%3A1999.02.0021&layout=&loc=18 {{Webarchive|url=https://web.archive.org/web/20091214003136/http://old.perseus.tufts.edu/cgi-bin/ptext?doc=Perseus%3Atext%3A1999.02.0021 |date=14 December 2009 }} February, 2.45 Martial also mentions a number of same-sex marriages, but always in derisory terms against people whom he wants to mock.Martial 12.42, 1.35, 3.93, 12.95.

At least two of the Roman Emperors were in same-sex unions; and in fact, thirteen out of the first fourteen Roman Emperors held to be bisexual or exclusively homosexual.Hinsch, Bret. (1990). Passions of the Cut Sleeve. University of California Press. pp. 35–36. The first Roman emperor to have married a man was Nero, who is reported to have married two other men on different occasions. First with one of his freedmen, Pythagoras, to whom Nero took the role of the bride, and later as a groom Nero married a young boy, who resembled one of his concubines,Nero missed her so greatly after her death that on learning of a woman who resembled her he at first sent for her and kept her; but later he caused a boy of the freedmen, whom he used to call Sporus,..."he formally "married" Sporus, and assigned the boy a regular dowry according to contract;" q.v., Suetonius Nero 28; Dio Cassius Epitome 62.28
