LGBT rights in Croatia

The Penal Code established on 27 May 1852 in the Habsburg Kingdom of Croatia (the first modern one in Croatian) did not specify homosexuality as a crime.[9] A subsequent draft of the new Penal Code for 1879 for the Kingdom of Croatia-Slavonia suggested male homosexual acts be punished with up to five years of prison, but the draft was never formally adopted.[10]

Partisan court martial verdict from 1944: Partisan captain Josip Mardešić found guilty and sentenced to death because of his homosexuality

During World War II, homosexual persons were prosecuted under various fascist regimes, but there is no record of organized persecution of homosexuals in the fascist Independent State of Croatia, whose laws did not explicitly contain a regulation directed against them.[11] The communist Yugoslav Partisans, however, issued at least one death sentence against a homosexual, Josip Mardešić, the commander of the Croatian Partisans' communication network until early 1944, when he was discovered to have had affairs with his male subordinates. Mardešić's sexual partners were not executed, only expelled from the Communist Party and reprimanded.[12][13]

During the period when Croatia was part of the Socialist Federal Republic of Yugoslavia, male homosexual acts were made illegal and punishable with up to two years of prison under the Penal Code of 9 March 1951.[14] However, the repression of homosexuals in Yugoslavia effectively began immediately after the end of the war. Homosexuals, labeled by communists as "enemies of the system", were also prohibited from joining the Communist Party of Yugoslavia.[15]

This situation changed when Croatia and other republics gained more control over their own legislature. Constitutional reforms in Yugoslavia in 1974 resulted in the abolishment of the federal Penal Code, allowing every republic to create its own. The Socialist Republic of Croatia created its own Code in 1977, and decriminalized homosexual activity. The Croatian Medical Chamber removed homosexuality from its list of mental disorders in 1973 – four years before the introduction of the new Penal Code, and seventeen years before the World Health Organization did the same.[11] Even though being a member of Yugoslavia meant Croatia was a communist country, it was never under the Iron Curtain, thus making it a relatively open country that was influenced by social changes in the wider developed world.[16]

The 1980s brought more visibility to LGBT people. In 1985, Toni Marošević became the first openly gay media person, and briefly hosted a radio show on the Omladinski radio radio station that dealt with marginal socio-political issues.[17] He later revealed that he had been asked on several occasions by the League of Communists of Croatia to form an LGBT faction of the party. The first lesbian association in Croatia, the "Lila initiative", was formed in 1989, but ceased to exist a year later.[11]

The 1990s brought a slowdown in terms of the progression of LGBT rights mainly as a result of the breakup of Yugoslavia followed by the Croatian War of Independence when many Croatian LGBT people, then involved in various feminist, peace and green organizations, joined the anti-war campaign within Croatia. Following Croatian independence, in 1992 the first LGBT association was officially formed, under the name of LIGMA (lezbijska i gej akcija, 'lesbian and gay action',[18] sometimes referred to in English as the Lesbian and Gay Men's Association[19]). This only lasted until 1997 as the socio-political climate of the time proved hostile to the advancement of gay rights. The most significant event that occurred in the 1990s was the equalization of the age of consent for all sexual activity in 1998 (both heterosexual and homosexual). The situation stagnated until 2000 when a new government coalition, consisting mainly of parties of the centre-left and led by Ivica Račan, took power from the HDZ after their ten-year rule.[11] The new government coalition brought attention to rights of LGBT citizens of Croatia with the introduction of the Same-sex community law in 2003.[20]

The 2000s proved a turning point for LGBT history in Croatia with the formation of several LGBT associations (with the Rijeka-based lesbian organisation LORI in 2000 and ISKORAK in 2002 being among the first); the introduction of unregistered cohabitations; the outlawing of all anti-LGBT discrimination (including recognition of hate-crime based on sexual orientation and gender identity); and the first gay pride event in Zagreb in 2002 during which a group of extremists attacked a number of marchers. Despite that, later marches drew thousands of participants without incidents.[21] Several political parties as well as both national presidents elected in 2000s have shown public support for LGBT rights, with some politicians even actively participating in Gay Pride events on a regular basis.[11]

In early 2005 the Sabor rejected a registered partnerships proposal put forward by Šime Lučin (SDP) and the independent Ivo Banac.[22] Lucija Čikeš MP, a member of the then-ruling HDZ, called for the proposal to be dropped because "the whole universe is heterosexual, from the atom and the smallest particle; from a fly to an elephant". Another HDZ MP objected on the grounds that, "85% of the population considers itself Catholic and the Church is against heterosexual and homosexual equality". However, the medical and physical professions, and the media more generally rejected these statements in opposition, warning that all the members of the Sabor had a duty to vote according to the Constitution which bans discrimination on the grounds of sexual orientation.

In 2009, the governing Croatian Democratic Union (HDZ) party passed a controversial law restricting access to in vitro fertilisation (IVF) solely to married couples and heterosexual couples who could prove that they had been cohabitating for at least three years. HDZ initially attempted to pass the law restricting access to IVF solely to married couples, but due to strong public pressure HDZ amended the proposed law to allow access to IVF for non-married heterosexual couples as well. The Catholic Church actively supported the first legislative proposal, arguing that access to IVF should only be granted to married couples.[23] As HDZ is a self-declared Christian democratic party, the then Minister of Health and Social Welfare, Darko Milinović, indicated that the government took the Church's position on the matter seriously.[24][25][26][27][28]

In 2009, the European Committee on Social Rights found several discriminatory statements in a biology course textbook mandatory in Croatian schools. It ruled that the statements violated Croatia's obligations under the European Social Charter.[29]

The 2010s have been marked with a second annual gay pride event in Croatia in the city of Split, a third in Osijek, and the return in 2011 of the centre-left coalition sympathetic to gay rights after the eight-year rule by the conservative-led coalition.[11][30] The Croatian Government also introduced a Life Partnership Act which makes same-sex couples effectively equal to married couples in everything except full adoption rights.[21] In November 2010, the European Commission's annual progress report on Croatia's candidacy to the EU stated the number of homophobic incidents in Croatia provided concern, and that further effort had to be made in combating hate crime.[31] A 2010 resolution by the European Parliament expressed "concern at the resentment against the LGBT minority in Croatia, evidenced most recently by homophobic attacks on participants in the LGBT Pride parade in Zagreb; urges the Croatian authorities to condemn and prosecute political hatred and violence against any minority; and invites the Croatian Government to implement and enforce the Anti-Discrimination Law".[32]

In December 2011, the newly elected Kukuriku coalition government announced that the modernisation of the IVF law would be one of its first priorities. Proposed changes to the law would allow single women, whose infertility was treated unsuccessfully, access to IVF as well.[33] Other changes were also proposed concerning the freezing of embryos and the fertilization of eggs. The Catholic Church immediately indicated its public oppositions to these changes, stating that they had not been involved in the discussions as much as they should like to have been. The Church subsequently initiated a petition against the legislation, but the Minister of Health, Rajko Ostojić, announced that the law would be going ahead with no compromises.[34] When asked about his attitude on lesbian couples having access to IVF Ostojić said: "Gay is OK!"[35] On 13 July 2012, the new law came into force with 88 MPs voting in favour, 45 voting against, and 2 abstentions. A number of HNS MPs who are also members of the ruling coalition wanted lesbian couples to be included in the legal change as well, and expressed disappointment that their amendment was not ultimately accepted. Since the new law only allowed access to IVF to women who were either married or single and infertile, the law excluded lesbian couples.[36] However, the government justified the exclusion by arguing that the legislative change was only intended to deal with the issue of infertility.[37][38]

In July 2012, the Municipal Court in Varaždin dealt with a case of discrimination and harassment on the grounds of sexual orientation against a professor at the Faculty of Organization and Informatics at the University of Zagreb. The case was the first report of discrimination based on sexual orientation in accordance with the Anti-Discrimination Act. The court found that there had indeed been discrimination and harassment against the victim in the workplace, and the Faculty was prohibited from further hindering the victim's professional advancement.[39]

A lobby group established in 2013, "In the Name of the Family", led the call to change the Croatian national constitution so that marriage can only be defined as a union between a man and a woman. The Roman Catholic Church played a prominent role in this political campaign, and Cardinal Josip Bozanić of Zagreb issued a letter to be read in churches reminding people that "Marriage is the only union enabling procreation".[40] Subsequently, a national referendum was held on 1 December 2013 where voters approved the change. Franko Dota, a gay rights activist, criticised the results, arguing that it was intended "to humiliate the gay population, and to strike against the progress of the past decades". Stephen Bartulica, a proponent of the referendum and a professor at the Catholic University of Croatia, countered that "the vote was an attempt to show that there is strong opposition" to "gay marriage and adoption by gays". The prime minister, Zoran Milanović, was unhappy that the referendum had taken place at all, saying, "I think it did not make us any better, smarter or prettier."[21]

On 1 March 2013, the Minister for Science, Education and Sports, Željko Jovanović, announced that his ministry would begin an action to remove all homophobic content from books used in both elementary and high schools. He wanted to especially target religious education books (religious education in Croatian schools is an optional course).[41]

On 11 May 2012, Milanović announced a further expansion to the rights of same-sex couples through a new law which would replace the existing unregistered cohabitation legislation. The Sabor subsequently passed the "Life Partnership Act" on 15 July 2014. This law effectively made same-sex couples equal to heterosexual married couples in everything except adoption rights. An institution similar to step-child adoption called "partner-guardian" was created to deal with the care of children.[42][43] [44]

In March 2014, it was announced that Croatia had granted asylum for the first time to a person persecuted on the basis of their sexual orientation – a young man from Uganda who had fled the country as a result of the Uganda Anti-homosexuality Act.[45]

The first life partnership in Croatia took place in Zagreb on 5 September 2014 between two men.[46] Within a year of the Sabor passing the law 80 life partnerships were conducted. By the end of 2016 that number had risen to 174.[47][48] In October 2018, it was reported that a total of 262 life partnerships had been conducted in Croatia between September 2014 and June 2018.[49][50]

In May 2016, Zagreb Pride published the first Croatian guide for same-sex couples, LGBT parents and families named "We Have a Family!". The publication was intended for informing same-sex partners and LGBT parents and contains information about life partnership, same-sex couples rights and the possibilities of planning LGBTIQ parenting in Croatia, as well as parenting stories written based on the experience of actual Croatian LGBT parents.[51] The publication was financed by the European Union and the Government of Croatia.

In December 2016, scientists Antonija Maričić, Marina Štambuk, Maja Tadić Vujčić and Sandra Tolić published a book, I'm Not Gay Mom, I'm Mom, in which they presented results of their research on the position of the LGBT families in Croatia, first such in the country. It provides insight into the types and characteristics of family communities, the quality of parenting, family climate and quality of relationships, a psychosocial adaptation of children, as well as experiences of stigmatization and discrimination and support in the contemporary Croatian society.[52]

The organization Rainbow Families (Croatian: Dugine obitelji) gathers LGBT couples and individuals who have or want to have children. It was organized by Zagreb Pride in 2011 as an informal group for psychosocial support led by psychologists Iskra Pejić and Mateja Popov. It was formally registered with the Ministry of Public Administration in 2017.[53] In 2018, it gathered around 20 LGBT families with children.[54] On 18 January 2018, Rainbow Families published the first picture book depicting same-sex couples with children in the Balkans, titled My Rainbow Family.[54] It was authored by Maja Škvorc and Ivo Šegota, and illustrated by Borna Nikola Žeželj. The picture book depicts thumbnails from the lives of two children: girl Ana, who has two dads, and boy Roko, who has two mothers. The aim of the picture book was to strengthen the social integration of children with same-sex parents and to promote tolerance and respect for diversity. It is intended for children of preschool age. The first edition of 500 copies was printed with the financial support of the French Embassy to Croatia and distributed for free to interested citizens and organizations. Since the entire first edition was distributed almost immediately, the organization started a crowdfunding campaign with an intention to collect funds for publishing 1000 new free hardback copies in both Croatian and English, as well as 1,000 copies of a new coloring book. In just under 24 hours, they surpassed two targeted goals and received more than $7,000 of initial $3,000 goal.[55][56]

In September 2020 gay couple Mladen Kožić and Ivo Šegota became the first same-sex foster parents in history of Croatia, after a three-year long legal battle. They became foster parents to two children.[57]

In 2022, a final court judgement allows same-sex couples to adopt children (both stepchild and joint adoptions).

A life partner who is not a legal parent of their partner's child or children can gain parental responsibilities on a temporary or permanent basis. As part of a "life partnership", the parent or parents of a child can temporarily entrust their life partner (who is not a biological parent) with parental rights. If those rights last beyond 30 days, then the decision must be certified by a notary. Under this situation, while the parental rights endure then the parent/parents and the life partner must agree collectively on decisions important for the child's well-being. In case of a dissolution of a life partnership, the partner who is not the biological parent can maintain a personal relationship with the child provided the court decides it is in the child's best interest.[69]

"Partner-guardianship" is a mechanism created under the Life Partnership Act that enables a life partner who is not a biological parent to gain permanent parental rights, and is thus similar to stepchild adoption. Such a relationship between the non-parent life partner and the child may be continued if the parent-partner dies (under the condition that the other parent has also died), is considered unknown, or has lost their parental responsibilities due to child abuse. However, the non-parent life partner can also ask for the establishment of partner-guardianship while the parent-partner is alive under the condition that the other parent is considered unknown or has lost parental responsibilities due to child abuse.[69][70]

The partner-guardian receives full parental responsibility as is the case with stepchild adoption, and is registered on the child's birth certificate as their partner-guardian. Partner-guardianship is a permanent next-of-kin relationship with all the rights, responsibilities, and legal standing as that of a parent and a child.[71][64] The first case of a partner-guardianship was reported in July 2015.[72]

In December 2018, the Croatian Parliament passed The Act on Fostering with 72 votes for, 4 against and 6 abstainers.[73]™Croatian gay rights groups slammed a new law that blocks same sex couples from becoming foster parents, although ahead of the vote, more than 200 prominent Croatian psychologists and sociologists in a statement voiced hope that lawmakers would not be led by "prejudices and stereotypes" and deprive children of a chance to be paired with foster parents "regardless of their sexual orientation". The activists vowed to fight it in the country's top court. Afterwards, Mladen Kožić and Ivo Šegota, a gay couple aspiring to become foster parents, wrote an open letter to the government saying that by "refusing to include life partners' families in the law ... you further boosted stigma and gave it a legal framework."[74][75][76] The law came into effect on 1 January 2019.

On 20 December 2019 it was reported that aforementioned couple did win a court battle that allowed them to become foster parents. Zagreb Administrative Court annulled previous decisions including the refusals of the Center for Social Welfare and the ministry. The court decision is final, and no appeal is allowed. Their attorney Sanja Bezbradica Jelavić stated: "The court's decision is binding, and an appeal is not allowed, so this judgment is final. The written ruling has not yet arrived, but as stated during the announcement, the court accepted our argument in the lawsuit, based on Croatian regulations and the European Convention on Human Rights. As a result, the court ordered the relevant government agencies to implement the new decision in accordance with the judgment. We believe that the agencies will respect the court decision."[77]

However, despite this decision, Center for Social Welfare rejected their application for the second time. The case was put before the Constitutional Court of Croatia, and on 7 February 2020 it reached the decision that same-sex couples have the right to be foster parents. In its summary, the Constitutional Court of Croatia says: "The Constitutional Court found that the impugned legal provisions which left out ('silenced') a certain social group produces general discriminatory consequences against same-sex persons living in formal and informal life partnerships, which is constitutionally unacceptable." The president of the Constitutional Court of Croatia Miroslav Šeparović further stated:""The point of this decision is that opportunity to provide foster care service must be given to everyone under the same conditions, regardless of whether the potential foster parents are of same-sex orientation. This does not mean that they are privileged, but their foster care must be allowed if they meet the legal requirements". The Constitutional Court did not repeal the challenged legal provisions, arguing that this would create a legal loophole, but stated unequivocally that the exclusion of same-sex couples from foster care was discriminatory and unconstitutional, and provided clear instructions to the courts, social welfare centers, and other decision-making bodies regarding these issues and indicated they must not exclude applicants based on their life partnership status. Constitutional judges stressed that, despite not intervening in the legal text, "courts or other competent bodies that directly decide on individual rights and obligations of citizens in resolving individual cases are obliged to interpret and apply laws in accordance with their meaning and legitimate purpose, to make those decisions on the basis of the constitution, laws, international treaties and other sources of law." Nine judges voted for this decision, and four were against. Two out of those four were of an opinion that Sabor should be allowed to change the current Foster Care act, and the other two were of an opinion that the law did not discriminate same-sex couples.[78][79]

Since 2006, the country has had hate crime legislation in place which covers sexual orientation. The law was first applied in 2007, when a man who violently attacked the Zagreb Pride parade using Molotov cocktails was convicted and sentenced to 14 months in prison.[85][86] On 1 January 2013 new Penal Code has been introduced with the recognition of a hate crime based on a gender identity.[62]

LGBT associations Zagreb Pride, Iskorak and Kontra have been cooperating with the police since 2006 when Croatia first recognized hate crimes based on sexual orientation. As a result of that cooperation the police have included education about hate crimes against LGBT persons in their training curriculum in 2013. In April of the same year the Minister of the Interior, Ranko Ostojić, together with officials from his ministry launched a national campaign alongside Iskorak and Kontra to encourage LGBT persons to report hate crimes. The campaign has included city light billboards in four cities (Zagreb, Split, Pula, and Osijek), handing out leaflets to citizens in those four cities, and distributing leaflets within police stations across the country.[87]

The only known case of discrimination in the Croatian Army is the 1998 case of recruit Aldin Petrić from Rijeka. In July 1998, Petrić answered his draft summons and reported to the barracks at Pula where he told his senior officer in a private conversation that he was gay; however, that information quickly spread through the barracks, which resulted in Petrić being subjected to abuse by his fellow soldiers and other officers. Petrić repeatedly asked to be transferred to another barracks but his requests were not met. On 22 July, Petrić was dismissed from the army because of "unspecified disturbance of sexual preference" (Code F65.9 from the 1992 ICD-10 Classification of Mental and Behavioral Disorders of the World Health Organization, which, however, has not specifically cited homosexuality as psychological disorder). Following Petrić's dismissal from Army, his parents found out about his homosexuality and expelled him from home. Petrić then sued Ministry of Defense for damages, citing "discriminatory policies, official impunity for the suffered abuse, and psychological trauma". In October 1998, the Ministry summoned Petrić once again in order for him to complete his military service which he refused fearing for his life. Afterwards Petrić sought and received political asylum in Canada.[94][95]

There have been other attacks on LGBT persons, the last one, in 2021. In Split, a representative of the LGBT community was beaten, when he decided to swim in the sea. Two people attacked him, ran away and left him injured. The mayor of Split also reacted, strongly condemning the attack.[96]

2007 Zagreb Pride

LGBT flags in Zagreb during the Zagreb Pride Week

The first pride in Croatia took place on 29 June 2002 in the capital city of Zagreb. Public support is growing and number of participants is also increasing rapidly year after year, but the marches have also experienced violent public opposition.[117] In 2006, the march had a regional character, aimed at supporting those coming from countries where such manifestations are expressly forbidden by the authorities. The 2011 manifestation was the biggest Pride rally in Croatia at the time, and took place without any violent incidents. It was also reported that the number of policemen providing security at the event was lower than had been the case in previous years. As of summer 2019, the 2013 event was the biggest one so far, with 15,000 participants.[118][119][120][121]

The first LGBT pride in Split took place on 11 June 2011. However, the march proved problematic as official security was not strong enough to prevent serious incidents, as a result of which LGBT attendees had to be led to safety. Several hundred anti-gay protesters were arrested, and the event was eventually cancelled.[122] Soon after the event, sections of the national media voiced supported for LGBT attendees, calling on everyone to "march in the upcoming Zagreb Pride".[123] On 9 June 2012, several hundred participants marched in Rijeka, the third largest city in Croatia. The march was organised to support Split Pride.[124] A second attempt at holding an event in 2012 was more successful, after receiving public support from the Croatian media, national celebrities, and politicians. Five ministers from the government and other public figures participated. In 2013, the march went ahead without a single incident, and it was the first time in Croatia that the mayor of the city participated.[125][126][127][128][129][130][131]

The first LGBT pride march in Osijek took place on 6 September 2014. It was organized by the Osijek LGBT association LiberOs. There were no incidents, and over 300 people attended. The Minister of the Economy, as well as Serbian and Greek LGBT activists attended.[132]

March for marriage equality, 2013

On 27 May 2013, around 1,500 participants in Zagreb marched in support of marriage equality from the park of Zrinjevac to St. Mark's Square, the seat of the Croatian Government, Croatian parliament, and the Constitutional Court of Croatia.[133] On 30 November 2013, one day before the referendum took place, around a thousand people marched in the city of Zagreb in support of marriage equality. Marches of support also took place in Pula, Split, and Rijeka gathering together hundreds of people.[134]

The first ever Trans Inter march in the Balkans took place in Zagreb on 30 March 2019. Around 300 people marched through the streets of Zagreb calling for better protection of intersex children, and general end to discrimination. Guest from Slovenia, Serbia, Romania, Germany, United Kingdom, Switzerland, and Bosnia and Herzegovina joined the march. It was organized by Trans Aid, Trans Network Balkans, and Spektra. The march took place without any incidents.[135]

The former Croatian President, Ivo Josipović, has given strong support to full LGBT rights, along with several other popular celebrities and centre-left political parties such as the Social Democratic Party of Croatia (SDP), the Croatian People's Party-Liberal Democrats (HNS), the Croatian Social Liberal Party (HSLS), ORaH, and the Labour Party. After Josipović was elected, he met with LGBT associations several times. On 1 June 2012, he published a video message giving support to the 2012 Split Pride and the further expansion of LGBT rights. He also condemned the violence at the 2011 Split Pride, calling it unacceptable and arguing that the next Split Pride should not experience the same scenario.[136] In October 2013 at a reception at the Presidential Palace he welcomed the newly appointed Finnish ambassador and his life partner to Croatia.[137][138]

Vesna Pusić, a member of HNS, is very popular within the Croatian LGBT community. She has been active in improving LGBT rights while being a member of successive governments. A former member of the SDP, current president of ORaH and a former Minister for Environment and Nature Protection in the Kukuriku coalition Mirela Holy has also been a notable long-time supporter of LGBT rights, and has participated in every LGBT Pride event so far.[139]

Other supporters of LGBT rights in Croatia are Rade Šerbedžija, Igor Zidić, Slavenka Drakulić, Vinko Brešan, Severina Vučković, Nataša Janjić, Josipa Lisac, Nevena Rendeli, Šime Lučin, Ivo Banac, Furio Radin, Darinko Kosor, Iva Prpić, Đurđa Adlešič, Drago Pilsel, Lidija Bajuk, Mario Kovač, Nina Violić, former Prime Minister Ivica Račan's widow Dijana Pleština, Maja Vučić, Gordana Lukač-Koritnik, pop group E.N.I. etc.[140]

Damir Hršak, a member of the Labour party, who has publicly spoken about his sexual orientation and has been involved in LGBT activism for years, is the first openly gay politician to become an official candidate for the first European Parliament elections in Croatia, held in April 2013. He had criticized the current coalition government for not doing enough for the LGBT community, and said that his party would not make concessions, and is in favour of same-sex marriage.[141][142][143]

Conservatives such as Ruža Tomašić have also indicated that same-sex couples should have some legal rights. The Croatian President Kolinda Grabar-Kitarović while against same-sex marriage, did indicate her support for the Life Partnership Act praising it as a good compromise. She also included sexual minorities in her inaugural speech, and said she would support her son if he was gay.[144][145] During the referendum, the conservative former Prime Minister, Jadranka Kosor, voted in favour of presenting the issue before the Constitutional Court, and against the proposed Constitutional change. This was a change from her previous position on homosexuality and same-sex marriage where she had been known for being against the expansion of LGBT rights, and subsequently voted "homophobe of the year" in 2010 by visitors of the website "Gay.hr" after stating that homosexuality is not natural, and that same-sex marriages should never be legal.[146] She also supported the Life Partnership Act.[147][148][149][150]

On 16 June 2011, 73 professors and associates of Zagreb Faculty of Law signed a statement initiated by the professor Mihajlo Dika, in which they expressed their full support for 2011 Zagreb Pride, and their support for the authorities in preventing and sanctioning behavior endangering equality and fundamental rights and freedoms of Croatian citizens effectively and responsibly. They also condemned hooligans that attacked the participants of the 2011 Split Pride.[151][152]

In February 2019, a new left-wing and green political party formed by local green and leftist movements and initiatives called We Can! – Political Platform appeared on the political scene. The party has expressed support for full LGBT rights. In 2020 the party won seats in Sabor, and after the 2021 local elections in Zagreb they became the largest political party in the Zagreb Assembly, winning 23 seats in total. Their mayoral candidate, Tomislav Tomašević won a landslide victory on May 31. He participated in Zagreb Pride in the past, but in 2021 for the first time as a mayor, which was also the first time a mayor of Zagreb attended the Pride.[153][154]

Results of the referendum by county

The largest conservative party in Croatia, the Croatian Democratic Union (HDZ), remains opposed to LGBT rights. HDZ MPs voted against the proposed law on unregistered cohabitations, and against the Life Partnership Act.[155] Since Croatian independence, HDZ has managed to form a majority in the Sabor on its own or with coalition partners in 6 out of 8 Parliamentary elections (1992, 1995, 2003, 2007, 2015, 2016). The party has, nevertheless, enacted several laws that ban discrimination on the basis of sexual orientation and gender identity as part of the negotiation process prior to the accession of Croatia to the European Union.[156] The Croatian Democratic Alliance of Slavonia and Baranja (HDSSB), a regionalist and right wing populist party formed in 2006 is also opposed to LGBT rights. During the Parliamentary debate on the Life Partnership Act, Dinko Burić, HDSSB MP stated his opposition to the law: "For us, being gay is not ok!" He also added that this is his party's official stand on LGBT rights. HDSSB MPs supported the 2013 referendum by having the word FOR on top of their laptops in Parliament.[157][158] Contrary to that, the president of HDSSB, Dragan Vulin, expressed his support for equal rights for same-sex couples in everything except adoption during the 2016 parliamentary election campaign.

Ruža Tomašić, leader of the Croatian Conservative Party has expressed her opposition to same-sex marriage on the grounds that Croatia is a majority Catholic country, but at the same time expressed her support for same-sex couples to receive equal rights to married couples in everything except adoption.[159] Her former deputy from the HSP Dr. Ante Starčević, Pero Kovačević, said that the 19th century Croatian politician Ante Starčević after whom the party has been named would not have opposed LGBT rights, and would have supported same-sex marriage. This was said in response to the youth-wing of the party organizing an anti-gay protest. The group later published an official letter expressing outrage to Kovačević's opposition to the protest.[160]

The Roman Catholic Church in Croatia has also been an influential and vocal opponent to the extension of LGBT rights in the country. After the first LGBT Pride in Split in 2011 some Catholic clergy even attempted to explain and justify the violence that had occurred during the Pride march. Dr. Adalbert Rebić argued that injured marchers had "got what they were asking for".[161] Meanwhile, Ante Mateljan, a professor in the Catholic Theology College, openly called for the lynching of LGBT marchers.[162]

The Catholic Church has also engaged at a political level, notably in providing public and vocal support for the 2013 referendum to define marriage in Croatia (and thus effectively reinforcing the existing prohibition on marriage between two people of the same gender). It was actively involved in collecting signatures for the petition to force a constitutional change. Cardinal Josip Bozanić encouraged support for the proposed constitutional amendment in a letter read out in all churches where he singled out heterosexual marriage as being the only union capable of biologically producing children, and thus worthy to be recognised.[163][164][165][166]

A conservative group "In the Name of the Family", formed in 2013, was the initiator of the 2013 referendum. The group opposes same-sex marriage, and any other form of recognition for same-sex unions. The most prominent member of the group, Željka Markić, opposed the Life Partnership Act claiming it was same-sex marriage under a different name, and thus a violation of the Constitution. She argued that the partner-guardianship institution proved most problematic under law.
