Same-sex marriage, also known as gay marriage, is the marriage of two people of the same legal sex. As of 2024,[update] marriage between same-sex couples is legally performed and recognized in 36 countries, with a total population of 1.5 billion people (20% of the world's population). The most recent jurisdictions to legalize same-sex marriage are Greece and Aruba and Curaçao in the Netherlands. Two more countries, Liechtenstein and Thailand, are set to begin performing same-sex marriages in January 2025.
Same-sex marriage is legally recognized in a large majority of the world's developed countries; notable exceptions are Italy, Japan, South Korea and the Czech Republic. Adoption rights are not necessarily covered, though most states with same-sex marriage allow those couples to jointly adopt as other married couples can. Some countries, such as Nigeria and Russia, restrict advocacy for same-sex marriage.[1] A few of these are among the 35 countries (as of 2023) that constitutionally define marriage to prevent marriage between couples of the same sex, with most of those provisions enacted in recent decades as a preventative measure. Other countries have constitutionally mandated Islamic law, which is generally interpreted as prohibiting marriage between same-sex couples.[citation needed] In six of the former and most of the latter, homosexuality itself is criminalized.
There are records of marriage between men dating back to the first century.[2]Michael McConnell and Jack Baker[3][4] are the first same sex couple in modern recorded history[5] known to obtain a marriage license,[6] have their marriage solemnized, which occurred on September 3, 1971, in Minnesota,[7] and have it legally recognized by any form of government.[8][9] The first law providing for marriage equality between same-sex and opposite-sex couples was passed in the continental Netherlands in 2000 and took effect on 1 April 2001.[10] The application of marriage law equally to same-sex and opposite-sex couples has varied by jurisdiction, and has come about through legislative change to marriage law, court rulings based on constitutional guarantees of equality, recognition that marriage of same-sex couples is allowed by existing marriage law, and by direct popular vote, such as through referendums and initiatives.[11][12] The most prominent supporters of same-sex marriage are the world's major medical and scientific communities,[13][14][15] along with human rights and civil rights organizations,[16] while its most prominent opponents are religious fundamentalist groups.[17]Polls consistently show continually rising support for the recognition of same-sex marriage in all developed democracies and in many developing countries.
Scientific studies show that the financial, psychological, and physical well-being of gay people are enhanced by marriage, and that the children of same-sex parents benefit from being raised by married same-sex couples within a marital union that is recognized by law and supported by societal institutions. At the same time, no harm is done to the institution of marriage among heterosexuals.[18] Social science research indicates that the exclusion of same-sex couples from marriage stigmatizes and invites public discrimination against gay and lesbian people, with research repudiating the notion that either civilization or viable social orders depend upon restricting marriage to heterosexuals.[19][20][21] Same-sex marriage can provide those in committed same-sex relationships with relevant government services and make financial demands on them comparable to that required of those in opposite-sex marriages, and also gives them legal protections such as inheritance and hospital visitation rights.[22] Opposition is based on claims such as that homosexuality is unnatural and abnormal, that the recognition of same-sex unions will promote homosexuality in society, and that children are better off when raised by opposite-sex couples. These claims are refuted by scientific studies, which show that homosexuality is a natural and normal variation in human sexuality, that sexual orientation is not a choice, and that children of same-sex couples fare just as well as the children of opposite-sex couples.[13]
Michael McConnell (75) and husband Jack Baker (75) talk with friend Lisa Vecoli (55) about having the first same-sex marriage legally recognized by a U.S. civil government in 1971, why they chose to get married, and what the response to their marriage was like.
JB describes the decades-long (46-year) process from the denial of their marriage license in 1971 until a second request that same year in Blue Earth County, Minnesota, was "declared to be in all respects valid" by Order of Gregory J. Anderson, Judge of District Court.
