The acceptance of homosexuality in Dacian space occurs once with the transformation of Dacia into Roman province and the inoculation of Roman concepts of society and culture to autochthonous population.
Middle Ages are characterized by social regression in the Romanian space, and the Christianization by Saint Andrew in Dobruja and the positioning on the border of religions (anti-Muslim shield) amplify bigotry. There is evidence of harsh punishment of homosexual acts although only for the poor, nobility enjoying all sexual privileges. However, examples of homosexual acts or relationships in that period can be retrieved in Dan Horia Mazilu's book, Voievodul, dincolo de sala tronului:
1929 – Pamfil Șeicaru names writer Panait Istrati "poor poet of deflowered arses". Istrati is the first Romanian author to write a novel – Chira Chiralina – in which a character is homosexual.
1933 – Writer Geo Bogza is imprisoned for a short time in Văcărești penitentiary for indecent behavior. Bogza just published the volume of poetry Poemul invectivă. One of his creations is about a pederast. Nicolae Ceaușescu was also imprisoned in Doftana, in the 1930s, for communist agitation. After the Revolution, there were allusive discussions about homosexual relationships that young Ceaușescu would be maintained at Doftana with his colleagues of detention.
1936 – The Penal Code of Carol II passes in unlawfulness the consented homosexual relationship. Article 431 provides imprisonment for "acts of sexual inversion" when provoking public scandal. Thus, any act of sexual inversion brought to public knowledge could be punished with imprisonment from six months to two years.
Under communist regime
1947 – The penalty for sexual inversion increases once with the installation of the communist regime. Thus, the mildest sentence was imprisonment for two years.
1957 – The Penal Code is amended again, pederasts being liable to imprisonment from three to ten years.
1968 – Homosexuality emerges as a linguistic term in the new Penal Code. Ideologically, homosexuality was unproductive for the Communists, who needed heroine mothers and an ascending demographic trend. The Grand National Assembly elaborates a completely revised version of the Penal Code, and sexual acts between persons of the same sex are considered crimes against the person and punished by Article 200: "sexual relations between persons of the same sex shall be punished with imprisonment from one to five years".
1977 – Ion Negoițescu, open homosexual, writes to anti-communist dissident Paul Goma, in sign of solidarity. Securitate prefers to rake in Negoițescu's intimate past than to arrest him for assault on national security, which would have blamed Romania internationally. Young writer Petru Romoșanu, wherewith Negoițescu would have homosexual relationships, is forced by Securitate to denounce as homosexual Negoițescu and other writers. Negoițescu has a suicide attempt with a dose of medication. Negoițescu and other gay writers escaped condemnation by the intervention of writer Ștefan Augustin Doinaș, deconspired after 1990s as Securitate collaborator.
1981–85 – "Morals" department of Bucharest Militia conducted an extensive investigation in this period. 54 gay Bucharesters should have been tried and convicted. But the case was stopped by Suzana Gâdea, Minister of Culture in those years, whereas among defendants appeared many artists and even officials of the Central Committee.
Ciprian Cucu (17) and Marian Mutașcu (22), two open homosexuals from Timișoara, were referred to the Police by Cucu's older sister. The two were arrested in January 1993. According to Cucu, "I was the first one to be interrogated. The investigators called me a 'whore' repeatedly...". On 9 June, both were convicted; Mutașcu received two years imprisonment, and Cucu one year. Largely due to intensive pressure from the international community, these sentences were suspended. In May 1995, Mutașcu committed suicide, due to public jesting.
Homosexuality brutally falls in public debate when popular musician Ioan Luchian Mihalea is killed by two of his sex partners, Nelu Florian Găvrilă and Ionel Păun. In the coming years, the media presents more cases of crimes of passion between homosexuals.
1995 – Mariana Cetiner (b. 1957) was arrested for allegedly trying to persuade another woman (Adina Vana) to have sexual intercourse with her. She spent three years in prison until was pardoned by President Emil Constantinescu at the insistence of Amnesty International. She was the last Romanian citizen to be imprisoned under Article 200.
2001 – The government adopts an emergency ordinance which repeals Article 200 of the Penal Code, in order to eliminate any discrimination on grounds of sexual orientation. The abrogation of the article was one of the conditions of EU accession.
2004 – ACCEPT organizes the first gay festival in Romania, under the title "Festival of Diversity", event that included a gay film festival, an exhibition of posters and photographs, book launches and public debates.
