The former Social Democratic Government appointed a commission to investigate the possibilities of same-sex marriages in Sweden.
In 2008, the Riksdag voted on a change in the law concerning marriages.
Same-sex sexual activity was legalized in 1944 and the age of consent was equalized in 1972.
Homosexuality was declassified as a mental illness in 1979.
The term Hom O was used both to refer to the office and the title of its government-appointed acting head; the last Hom O was Hans Ytterberg.After allowing same-sex couples to register for partnership benefits in 1995, Sweden became the seventh country in the world to legalize same-sex marriage countrywide in 2009.Discrimination on the basis of sexual orientation and gender identity and expression has been banned since 1987.These partnerships had all the rights of marriages except "as provided by sections 3–4" of the law.As well, all provisions of a statute or any other legislation related to marriage or spouses apply to registered partnerships and partners, except as under sections 3–4., new registered partnerships can no longer be entered into due to the legalization of same-sex marriage.
