SEXUALITY, GENDER & LGBTQ+ PROGRESS

Introduction: sexuality has a history

Sexuality is universal, but the ways societies name, regulate and understand it are not. Human beings have always formed relationships, experienced desire, created families and lived with bodies that do not fit simple social categories. Yet ideas such as “homosexuality”, “heterosexuality”, “bisexuality”, “transgender”, “non-binary” and even the modern distinction between sexual orientation and gender identity are comparatively recent.

For much of history, societies were more likely to classify sexual conduct by acts, status, age, marital role, social rank, religious law or gendered expectations than by a stable inner identity. A man who had sex with men in ancient Rome, for example, was not necessarily understood as belonging to a category equivalent to the modern identity “gay”. Historical interpretation therefore requires care.

At a glance: selected milestones

1. Ancient Mesopotamia and Egypt: evidence, ambiguity and interpretation

Mesopotamian religion contains some of the earliest written material relevant to gender variance. Priests and ritual specialists associated with the goddess Inanna/Ishtar included groups such as gala. Some texts portray gender transformation or role reversal in Inanna’s cult. However, older popular accounts sometimes move too quickly from this evidence to claims that these priests were straightforwardly “gay”, “transgender” or temple sex workers. The surviving evidence does not justify such simple equivalence.

Ancient Egyptian evidence is similarly intriguing but incomplete. The Fifth Dynasty tomb of Niankhkhnum and Khnumhotep depicts the two men in unusually intimate poses. Some scholars have interpreted them as a couple; others favour kinship explanations. The tomb is important precisely because it illustrates a recurring challenge in queer history: intimacy may be visible while the exact social meaning remains uncertain.

2. Ancient Greece: desire shaped by age, citizenship and gender

Ancient Greek societies did not organise sexuality around modern categories of gay and straight. In classical Athens, some socially recognised relationships linked an adult male citizen, the erastēs, with a younger male, the erōmenos. Such relationships were embedded in hierarchies of age, status and education and cannot be treated as direct equivalents of modern adult same-sex relationships.

Greek literature nevertheless provides rich evidence of same-sex desire. Plato’s Symposium contains multiple speeches about male-male love, while poetry associated with Sappho of Lesbos became foundational to later lesbian cultural memory. Female same-sex relationships are generally less well documented because surviving sources were overwhelmingly written by men.

3. Rome: status mattered more than orientation

Roman sexual norms were strongly structured by citizenship, masculinity and social rank. For a free adult male citizen, sexual reputation often turned less on the partner’s sex than on whether he was perceived to retain the dominant social role. Being sexually penetrated could be stigmatised when associated with loss of masculine status, although actual practice was far more varied than prescriptive texts suggest.

Emperor Hadrian’s relationship with the young Bithynian Antinous became exceptionally visible after Antinous died in the Nile in 130 CE. Hadrian had him deified, founded the city of Antinoöpolis and promoted his image across the empire. The episode is strong evidence of profound attachment, but again does not mean either man possessed a modern “gay identity”.

4. South Asia: sexual diversity, gender plurality and hijra histories

South Asian histories contain a wide range of representations of desire and gender. The Kama Sutra discusses sexual practices between men and between women rather than treating all such behaviour as unmentionable. Sanskrit literature and Hindu traditions include gender transformation, composite forms and deities who cross conventional gender boundaries, including Mohini and Ardhanarishvara.

Hijra communities have deep historical roots in South Asia and have held ceremonial, courtly and community roles. Their identities cannot be reduced neatly to Western categories such as “transgender”, “intersex” or “third gender”, although those terms may overlap with some individuals’ experiences today. Colonial governance, particularly British legal and administrative systems, increasingly stigmatised and criminalised gender-nonconforming communities.

5. China and Japan: same-sex intimacy without a modern identity system

Imperial China

Chinese sources record male-male intimacy across many dynasties. The famous “cut sleeve” story concerns Emperor Ai of Han and his favourite Dong Xian: later writers used the image of the cut sleeve as a literary euphemism for male same-sex love. Other phrases, such as the “shared peach”, similarly entered elite literary culture. Tolerance varied by period, region, class and political context, and family obligations to marry and produce heirs remained powerful.

Japan

In medieval and early modern Japan, male-male erotic traditions appeared in Buddhist, warrior and urban contexts. Nanshoku (“male colours”) and wakashudō described practices involving men and youths, while kabuki culture became associated with both gender performance and sexual commerce. As in Greece, age and hierarchy require careful treatment. Nineteenth-century modernisation and contact with Western sexology helped change the language through which such behaviour was understood.

6. Indigenous gender systems: beyond a Western binary

Many Indigenous societies developed gender roles that do not map neatly onto a European male/female binary. The modern pan-Indigenous North American term “Two-Spirit” was adopted in 1990 as an English-language umbrella term by some Indigenous LGBTQ+ people. It should not be retroactively used as though every Indigenous nation shared one identical pre-colonial category.

Other culturally specific identities include fa’afafine in Samoa and faʻafafine-related Pacific traditions, and muxes among Zapotec communities in Oaxaca, Mexico. These identities have their own histories, social roles and cultural meanings. Treating them simply as local versions of “gay men” or “trans women” can erase precisely what makes them distinctive.

7. Religion, law and the regulation of sexuality

Judaism, Christianity and Islam developed extensive moral traditions around sex, marriage and family life, but there has never been one unchanging religious response to same-sex behaviour. Texts have been translated and interpreted differently across centuries, and religious law often addressed acts rather than modern sexual identities.

In medieval and early modern Christian Europe, church and secular authorities increasingly punished categories grouped under “sodomy”, a term that could include several non-procreative sexual acts rather than only sex between men. Penalties varied enormously by place and period. In England, the Buggery Act 1533 transferred the offence into secular law and made it punishable by death.

Islamic legal traditions generally prohibited male anal intercourse, but historical Muslim societies also produced extensive homoerotic poetry and literature. Law, theology, desire and lived practice did not always align. Modern claims that a single timeless “Islamic attitude” explains every Muslim society therefore oversimplify a complex history.

8. Colonialism: exporting law, morality and categories

European colonialism transformed sexual regulation around the world. Missionaries and administrators often condemned Indigenous practices that conflicted with European Christian norms. British colonial penal codes were particularly influential: versions of laws criminalising “carnal intercourse against the order of nature” were replicated across Asia, Africa, the Caribbean and the Pacific.

Some modern states still enforce laws derived partly from these colonial legal traditions, although present-day politics, religion and nationalism have also reshaped them. It is therefore inaccurate to say that all contemporary anti-LGBT laws are simply colonial leftovers; but colonial legal architecture remains an important part of the story.

9. The nineteenth century: from acts to identities

A major conceptual shift occurred in nineteenth-century Europe. Medicine, psychiatry, law and sexology increasingly classified people according to enduring types of sexuality. The words “homosexual” and “heterosexual” emerged during this period. This change could be oppressive because it converted prohibited acts into supposedly abnormal kinds of person, but it also gave minorities language with which to organise and argue that their sexuality was innate rather than immoral.

Early reformers

Karl Heinrich Ulrichs argued in the 1860s that same-sex attraction was natural and deserved legal protection. Karl-Maria Kertbeny coined the term “homosexual” in 1869 while opposing Prussian anti-sodomy law. Magnus Hirschfeld later founded the Scientific-Humanitarian Committee and, in 1919, the Institute for Sexual Science in Berlin. His work encompassed homosexuality, cross-gender identities and sexual medicine and helped some people access early forms of gender-affirming care.

The Nazi destruction of Hirschfeld’s institute in 1933 became one of the most symbolic attacks on early sexual science. Nazi persecution under Paragraph 175 led to the arrest of tens of thousands of men; thousands were sent to concentration camps. Lesbian women were not prosecuted under Paragraph 175 in the same systematic way but could still be targeted as “asocial”, politically suspect or otherwise nonconforming.

10. Britain: criminalisation, Oscar Wilde and hidden lives

British law historically punished sex between men while female same-sex activity was never criminalised in the same way. Oscar Wilde’s 1895 conviction for gross indecency became one of the best-known examples of the social and legal destruction that could follow exposure. The Labouchere Amendment of 1885 had made “gross indecency” between men an offence even where buggery could not be proved.

Queer people nevertheless created subcultures. London’s molly houses had existed in the eighteenth century. In the twentieth century, theatres, clubs, private parties and friendship networks provided meeting places. Polari, a cant drawing on theatre, circus, Romani, Yiddish, Italianate and other vocabularies, became associated with gay male subculture and allowed coded recognition in hostile environments.

11. Sexology, psychiatry and the medicalisation of homosexuality

From the late nineteenth into the twentieth century, homosexuality was frequently classified as pathology. Psychoanalytic theories varied: Freud did not regard homosexual people as inherently immoral and opposed simplistic attempts to “cure” them, but he still interpreted sexual orientation through developmental theory. Later psychiatric systems more explicitly pathologised homosexuality.

Treatments imposed on lesbian, gay and bisexual people included aversion techniques, hormonal interventions and institutionalisation. Some were administered coercively. The history of these practices is one reason contemporary professional bodies distinguish supportive psychotherapy from interventions designed to force a predetermined change in sexual orientation.

The American Psychiatric Association removed homosexuality from the DSM in 1973 after scientific review and activism. WHO’s World Health Assembly ceased classifying homosexuality as a mental disorder on 17 May 1990. WHO’s current classifications explicitly state that sexual orientation by itself is not a disorder.

12. Transgender history and the evolution of medical classification

People who crossed or lived outside conventional gender roles long predate the word “transgender”. What changed in the twentieth century was the development of medical, legal and social categories describing gender identity and transition. Hirschfeld used terms such as “transvestite” in ways that do not map precisely onto present terminology. Later clinicians developed concepts including transsexualism and gender dysphoria.

Modern classifications have moved away from treating transgender identity itself as a mental disorder. ICD-11 replaced “transsexualism” in the mental-disorders chapter with “gender incongruence” in the chapter on conditions related to sexual health. WHO explains that this reflects evidence that trans-related identities are not, in themselves, mental disorders while retaining a code that can support access to healthcare.

13. The Wolfenden Report and the slow dismantling of British criminal law

In 1957 the Wolfenden Committee recommended that consensual homosexual conduct between adults in private should no longer be criminal. Its central argument was not that society had to approve of homosexuality, but that private morality and criminal law should not be identical.

The Sexual Offences Act 1967 partially implemented this recommendation in England and Wales. It applied only to men, required conduct to take place in private and set an age threshold of 21. It therefore did not create equality. Scotland did not decriminalise comparable conduct until 1980 and Northern Ireland until 1982, after a European Court of Human Rights ruling. The unequal age of consent persisted until 2001, when it became 16 across the UK.

14. Stonewall and gay liberation: a turning point, not the beginning

The Stonewall uprising began in the early hours of 28 June 1969 after police raided the Stonewall Inn in Greenwich Village. Patrons and people in the surrounding streets resisted over several nights. Stonewall was not the first LGBT protest or confrontation with police: organisations and demonstrations already existed in New York, Philadelphia, Washington, Los Angeles and San Francisco. Its significance lies in the scale of the mobilisation it helped catalyse.

Popular retellings sometimes say the uprising was “led by trans women of colour”. Trans and gender-nonconforming people, including Marsha P. Johnson and Sylvia Rivera, became major figures in the movement, but historians caution against reducing a spontaneous, multi-participant uprising to a single leader or first brick. Johnson and Rivera later co-founded STAR, which supported homeless gender-nonconforming young people.

15. Lesbian feminism, bisexual organising and tensions within liberation

The post-Stonewall movement was never a single community with one set of priorities. Lesbian feminists challenged sexism within gay organisations and homophobia within parts of the women’s movement. Bisexual activists argued against assumptions that attraction must be exclusively heterosexual or homosexual. Trans activists often faced exclusion even while contributing substantially to street-level organising.

These tensions shaped the eventual expansion from “gay rights” toward broader acronyms such as LGBT and LGBTQ+. The acronyms themselves remain historically contingent and culturally specific; many people use other terms, and some Indigenous or non-Western communities prefer culturally rooted identities.

16. HIV/AIDS: catastrophe, stigma, science and activism

AIDS was first recognised in 1981 in the United States, initially among gay men, but HIV is not a “gay disease”. It can be transmitted through blood, semen, vaginal and rectal fluids and breast milk and has affected heterosexual people, people who inject drugs, haemophiliacs, sex workers, children and many other populations worldwide.

Gay and bisexual men nevertheless suffered devastating mortality in North America and Western Europe, intensified by stigma and delayed political responses. ACT UP and other activist organisations transformed the relationship between patients, regulators, pharmaceutical companies and researchers. Activists demanded faster trials, compassionate access to treatment, anti-discrimination measures and public education.

The scientific landscape is now radically different. Effective antiretroviral therapy can suppress HIV to undetectable levels. The principle U=U — undetectable equals untransmittable — reflects evidence that people who maintain an undetectable viral load do not sexually transmit HIV. Pre-exposure prophylaxis (PrEP) provides highly effective prevention for HIV-negative people at substantial risk.

17. From decriminalisation to equality law

From the 1990s onward, legal change accelerated in many countries. Constitutional courts and legislatures decriminalised same-sex intimacy, prohibited discrimination, opened adoption and military service, created registered partnerships and ultimately recognised same-sex marriage. The Netherlands became the first country to allow same-sex civil marriage in 2001.

In the UK, civil partnerships were introduced in 2004. The Marriage (Same Sex Couples) Act 2013 opened marriage to same-sex couples in England and Wales, with the first marriages on 29 March 2014. Scotland legislated separately in 2014. Same-sex marriage became lawful in Northern Ireland in 2020.

18. The UK legal framework in 2026

The Equality Act 2010 protects people in Great Britain from unlawful discrimination based on sexual orientation and gender reassignment, alongside sex and other protected characteristics. These protections apply across important areas including employment, education, services and housing, subject to statutory exceptions.

A major legal development occurred on 16 April 2025, when the UK Supreme Court unanimously held in For Women Scotland Ltd v The Scottish Ministers that the terms “sex”, “man” and “woman” in the Equality Act 2010 refer to biological sex. The Court also expressly stated that this interpretation does not remove discrimination protection from trans people, who remain protected under gender reassignment and can rely on other Equality Act provisions in relevant circumstances.

The Gender Recognition Act 2004 remains the statutory route by which eligible adults can obtain a Gender Recognition Certificate. The interaction between the GRA and Equality Act is therefore now understood in light of the 2025 Supreme Court judgment. This is an area of active policy, legal and public debate, and descriptions of the law should distinguish clearly between legal sex concepts, gender identity and anti-discrimination protection.

19. Children and young people: a rapidly changing clinical area

Care for children and adolescents with gender-related distress has become one of the most contested areas in modern sexual and gender health. In England, the closure of the Tavistock Gender Identity Development Service and implementation of recommendations following the Cass Review led to a new regionalised NHS model emphasising holistic assessment, mental and physical health, neurodevelopment, family context and careful evidence review.

In December 2024 the UK government made restrictions on the sale and supply of puberty-suppressing hormones for gender dysphoria/incongruence in under-18s indefinite outside specified research arrangements, with a review planned for 2027. NHS England’s 2026 service specification continues to embed a holistic assessment framework. This policy applies to a specific paediatric clinical context and should not be misrepresented as a general statement about adult transgender healthcare or about the legitimacy of transgender identities.

20. Conversion practices: from “treatment” to human-rights concern

Practices intended to force or pressure people to change sexual orientation or gender identity have included psychotherapy, religious interventions, behavioural techniques, coercion and abuse. Mainstream health organisations do not regard homosexuality as a disorder requiring treatment. Supportive therapy may explore relationships, distress, identity or uncertainty; that is different from treatment with a predetermined goal of making a person heterosexual or cisgender.

As of August 2026, England and Wales do not yet have the final new statutory regime proposed by the current government. A Draft Conversion Practices Bill was published on 25 June 2026 for pre-legislative scrutiny. It proposes offences targeting abusive conduct intended to change a person’s sexual orientation or transgender identity, as well as protection orders, while stating that legitimate healthcare, therapy, ordinary conversations and freedom of expression require safeguards. A joint parliamentary committee is due to report by 22 January 2027.

21. Global legal position in 2026: progress and reversal

Global progress is substantial but highly uneven. ILGA World’s June 2026 data report that 65 UN member states still criminalise consensual same-sex sexual acts. The total rose in 2025 for the first time in almost a decade. The death penalty is legally prescribed for consensual same-sex sexual acts in seven UN member states, with legal uncertainty in several more.

At the same time, marriage equality exists in 37 UN member states plus Taiwan. Seventeen UN member states have nationwide bans on so-called conversion therapies, and legal gender recognition based on self-determination exists in a smaller group of jurisdictions. These headline figures change frequently and should be dated whenever published.

The contemporary pattern is therefore not one of inevitable liberalisation. Decriminalisation and recognition continue in some countries while other governments expand criminal penalties, restrict LGBT-related expression or constrain civil-society organisations.

22. Uganda, Russia and the problem with shorthand

Uganda’s Anti-Homosexuality Act 2023 introduced severe penalties, including the possibility of the death penalty for the statutory offence of “aggravated homosexuality”. It is more accurate to describe the exact legal provision than to say simply that “Uganda introduced the death penalty for being gay”, because identity, conduct and statutory offences are not legally identical.

Russia has progressively expanded restrictions on public expression associated with LGBT identities, including broad “propaganda” provisions and later measures directed at what the state calls the “international LGBT movement”. These laws have been widely criticised by human-rights organisations for restricting expression, association and safety.

23. Digital life: visibility, community and new forms of risk

The internet fundamentally changed LGBTQ+ life. People in isolated communities can find language, peers, health information and social support without first entering a physical gay or trans venue. Online networks have enabled rapid mobilisation around Pride, equal marriage, anti-violence campaigns and legal reform.

Digital visibility also creates risk. Dating apps can expose location and identity. Governments and hostile actors may use digital evidence for surveillance or entrapment. Social platforms can amplify harassment and misinformation as easily as solidarity. For young people, online communities can be supportive but should not be treated as substitutes for safe offline relationships, high-quality healthcare or safeguarding where these are needed.

24. Intersectionality: sexuality never exists in isolation

The term intersectionality, developed by legal scholar Kimberlé Crenshaw in the context of race and sex discrimination, is useful for understanding how sexuality and gender interact with race, disability, class, religion, migration status and other dimensions of life. A wealthy gay man in a legally protective city may encounter very different risks from a lesbian asylum seeker, a disabled trans person or a queer young person dependent on a hostile family.

Intersectionality should not become a claim that identities mechanically determine experience. It is an analytic reminder that social disadvantages can combine, and that policies designed around a single category may miss people living at their intersection.

25. Pride, representation and commercialisation

Pride developed from political protest and remembrance but now ranges from radical marches to large civic and commercial festivals. Corporate sponsorship can provide money, legitimacy and safer public space, while critics argue that commercialisation may dilute protest or allow organisations to signal inclusion without changing discriminatory practices.

Representation in film, television, sport, politics and advertising has expanded enormously. Visibility can reduce isolation and widen the imaginable range of lives, but it does not automatically guarantee legal equality or social safety. Representation also raises questions about stereotyping, who gets to tell stories and whether affluent Western experiences dominate global narratives.

26. Intersex people: an often-misunderstood part of the story

Intersex is an umbrella term for innate variations in sex characteristics. Intersex people may be male, female or use other descriptions; they may be heterosexual, gay, lesbian, bisexual or asexual; and they may or may not be transgender. Intersex therefore should not be treated as another word for non-binary or trans.

A major contemporary human-rights issue concerns medically unnecessary or deferrable interventions on infants and children with variations in sex characteristics before they can participate in decision-making. A growing number of jurisdictions have introduced restrictions, while clinicians and advocates continue to debate how best to balance bodily autonomy, medical need, parental involvement and long-term health.

27. Asexuality and the broadening map of sexuality

• Modern sexuality discourse increasingly recognises asexuality: little or no sexual attraction, which is distinct from celibacy, abstinence or loss of libido due to illness or medication. Some asexual people experience romantic attraction and use labels such as heteroromantic, homoromantic, biromantic or aromantic. The development of online asexual communities illustrates how new identity language can make previously isolated experiences socially legible.

28. What has genuinely changed?

Over the past century, several transformations are difficult to overstate. Same-sex intimacy has moved from criminal offence to legally recognised marriage in many jurisdictions. Homosexuality has moved from psychiatric diagnosis to recognised normal variation in human sexuality. Transgender people have gained legal-recognition pathways in numerous countries. HIV has changed from an almost uniformly fatal infection to a manageable chronic condition when effective treatment is available.

Yet progress is not linear or universal. Criminalisation remains extensive, political backlash has intensified in some states, and LGBT people continue to experience violence, family rejection, discrimination and health disparities. The correct historical conclusion is therefore neither “everything is solved” nor “nothing has changed”. Both progress and continuing risk are real.

29. How to discuss sexuality history responsibly

·       Do not apply modern identity labels automatically to ancient people. Describe the evidence first: behaviour, relationship, role, text or self-description.

·       Distinguish consensual adult same-sex relationships from historically institutionalised relationships involving adolescents, slavery or unequal status.

·       Distinguish sexual orientation, gender identity, gender expression and intersex variations.

·       Avoid presenting “religion” as a single unchanging force; interpretation varies by tradition, period and community.

·       Be precise about criminal law. A law may criminalise a particular sexual act, public expression or organisation rather than the mere possession of an identity.

·       Do not erase colonial influence, but do not assume every contemporary anti-LGBT policy has only a colonial cause.

·       Use current dates for global legal statistics because decriminalisation, marriage recognition and restrictive laws change rapidly.

·       Recognise disagreement in contested medical or legal areas rather than presenting advocacy language as settled scientific fact.

• · Centre ordinary lives as well as persecution: relationships, family, art, humour, work, religion and community are all part of LGBTQ+ history.

Continuity, change and human diversity

The strongest lesson from the history of sexuality is not that modern LGBTQ+ identities have existed unchanged for thousands of years. They have not. The deeper continuity is that human desire, intimacy, gender expression and bodily diversity have always exceeded the categories societies build around them.

Those categories matter. They can determine whether a relationship is celebrated, ignored, medicalised, criminalised or protected by law. They can create communities and political solidarity, but they can also oversimplify experiences that do not fit neatly within them.

• The modern LGBTQ+ rights story is therefore both new and ancient: new in its language, organisations, science and law, but rooted in much older human realities. Understanding that distinction gives us a history that is more accurate, more inclusive and more interesting than a simple march from repression to liberation.
