The 20th century was a transformative era for the LGBTQ community, unfolding across decades of profound social, political, and cultural change. Documenting this history is not merely an academic exercise; it is a vital act of preservation that ensures the struggles, triumphs, and everyday lives of LGBTQ individuals are not erased or forgotten. A thorough understanding of this century's arc can inform current activism and provide context for the rights and challenges faced today. This expanded account digs deeper into the key movements, individuals, and events that shaped queer life from the shadows of the early 1900s to the hard-won progress at the century's close.

Early 20th Century: Shadows and Beginnings

In the early 1900s, LGBTQ identities were largely hidden behind a veil of strict social mores and legal prohibitions. Homosexuality was criminalized in nearly every Western nation, and same-sex desire was often pathologized as a mental illness or moral failing. Despite this repressive environment, vibrant underground communities flourished in major cities like New York, Berlin, Paris, and London. These covert networks provided solace and a sense of belonging, often through bars, private clubs, and house parties. The sheer danger of exposure meant that many lives were lived in code, but a rich subculture persevered.

Pre‑World War II Agitation and Early Organizations

Though largely unknown to mainstream society, small but determined groups began organizing. In Germany, the Scientific‑Humanitarian Committee, founded in 1897 by Magnus Hirschfeld, campaigned against Paragraph 175, the law criminalizing homosexuality. The committee gathered thousands of signatures from prominent figures, including Albert Einstein, but ultimately failed to change the law. In the United States, the short‑lived Society for Human Rights, established in Chicago in 1924 by Henry Gerber, was the first known gay‑rights organization in the country. It was quickly suppressed after a police raid, but its existence demonstrated that the desire for organized advocacy existed long before the post‑war homophile movement.

The Harlem Renaissance of the 1920s and early 1930s offered a rare space of relative openness. African American artists, writers, and musicians, including figures like Langston Hughes, Countee Cullen, and Gladys Bentley, expressed same‑sex desire through their work and personal lives. This cultural explosion challenged mainstream ideas about race, gender, and sexuality, even as it remained vulnerable to police raids and public outrage. Bentley, a gender‑nonconforming performer, openly sang lesbian-themed lyrics and wore men's suits, pushing the boundaries of acceptable expression.

Medicalization and Scientific Oppression

During this period, the medical and psychiatric establishments heavily influenced public perceptions of homosexuality. Theories of degeneracy, inversion, and hormonal imbalance were common. Many LGBTQ individuals faced involuntary hospitalization, electroshock therapy, and other invasive "treatments." The work of early sexologists like Magnus Hirschfeld, who founded the Institute for Sexual Science in Berlin, offered a more humane, scientific perspective. But Nazi book burnings and the destruction of Hirschfeld’s institute in 1933 marked a devastating setback for research and advocacy. The institute's archive of thousands of books and photographs was burned, a deliberate erasure of a nascent scientific understanding of human sexuality.

Mid‑Century: Activism and the Birth of the Homophile Movement

World War II was a watershed moment. Wartime mobilization brought together men and women from all backgrounds, creating unprecedented opportunities for same‑sex encounters. Many young people discovered their identity in the gender‑segregated military and defense industries. The post‑war period, however, saw a fierce backlash. The Lavender Scare in the United States mirrored the Red Scare, leading to the mass firing of LGBTQ people from government jobs—an estimated 5,000 federal employees were purged. In this hostile climate, a new phase of organized activism emerged, often called the homophile movement, which emphasized respectability and legal reform.

The Mattachine Society and the Daughters of Bilitis

In 1950, Harry Hay and a small group of men founded the Mattachine Society in Los Angeles. The group initially adopted a semi‑secret structure, influenced by Communist cell models, and aimed to unite gay people to fight for their civil rights. By the mid‑1950s, under new leadership from figures like Hal Call, the organization became more mainstream, focusing on education and legal reform through conferences and publications. They held public forums and supported members facing legal troubles.

In 1955, the Daughters of Bilitis (DOB) was founded in San Francisco as the first lesbian‑focused organization in the United States. The DOB published The Ladder, a magazine that provided a vital platform for lesbian voices and helped build a national community. Meanwhile, the magazine ONE (started in 1953) and the founding of the ONE Institute became key vehicles for public education and advocacy. The U.S. Supreme Court's 1958 decision in ONE, Inc. v. Olesen ruled that the magazine was not obscene, a landmark victory for free expression and gay rights.

Pre‑Stonewall Flashpoints: San Francisco and the Compton’s Cafeteria Riot

Before the Stonewall riots captured global attention, a lesser‑known uprising took place in San Francisco’s Tenderloin district. In August 1966, transgender patrons and drag queens at Compton’s Cafeteria fought back against police harassment. The Compton’s Cafeteria riot was one of the first recorded instances of collective resistance by transgender people in the United States. It set the stage for more militant activism and highlighted the intersection of poverty, police brutality, and gender nonconformity. The event was largely forgotten until historian Susan Stryker documented it in the 1990s, recovering an essential piece of queer history.

Key Events and Figures That Defined the Movement

The Stonewall Riots (1969)

The Stonewall Inn, a mafia‑run bar in New York City’s Greenwich Village, had long been a refuge for the most marginalized members of the LGBTQ community, including drag queens, homeless youth, and people of color. When police raided the bar on June 28, 1969, the patrons—led by trans women of color like Marsha P. Johnson and Sylvia Rivera—fought back. The ensuing protests lasted several nights and galvanized a new generation of activists. Stonewall is widely credited as the catalyst for the modern LGBTQ rights movement, leading to the formation of groups like the Gay Liberation Front and the Gay Activists Alliance, and inspiring the first Pride marches in 1970 in New York, Los Angeles, and Chicago.

Harvey Milk: A Political Trailblazer

Harvey Milk was one of the first openly gay elected officials in the United States, winning a seat on the San Francisco Board of Supervisors in 1977. His brief but impactful career focused on anti‑discrimination legislation, coalition building, and visibility. Milk famously urged young gay people to come out, believing that personal honesty was the most powerful political tool. His assassination in 1978, along with Mayor George Moscone, shocked the nation and transformed him into a martyr for the movement. The White Night Riots that followed his assassin's light sentence underscored the community's rage and grief.

Removal of Homosexuality from the DSM (1973)

For decades, the American Psychiatric Association (APA) classified homosexuality as a mental disorder. Activist groups, led by figures like Frank Kameny and Barbara Gittings, staged protests at APA conferences and presented scientific evidence challenging the diagnosis. In 1973, the APA’s board of trustees voted to remove homosexuality from the Diagnostic and Statistical Manual of Mental Disorders (DSM). This decision was a monumental step toward depathologizing same‑sex desire and had far‑reaching legal and social implications. The change undermined a key justification for discrimination in employment, immigration, and family law.

Transgender Activism and the Rise of the Trans Rights Movement

Transgender individuals were often at the forefront of early activism but remained marginalized within mainstream gay organizations. Marsha P. Johnson and Sylvia Rivera co‑founded STAR (Street Transvestite Action Revolutionaries) in 1970 to support homeless transgender youth and sex workers. In later decades, activists like Christine Jorgensen, who underwent gender confirmation surgery in 1952, and Renée Richards, who fought to play professional tennis as a woman, brought trans visibility into public discourse. However, it was not until the 1990s that transgender rights gained widespread attention, culminating in events like the 1993 March on Washington for Lesbian, Gay and Bi Equal Rights, where trans activists demanded inclusion, and the founding of the Transgender Law Center in 2002.

Criminalization and Decriminalization

Throughout the 20th century, many countries maintained laws criminalizing same‑sex acts. In the United Kingdom, the Wolfenden Report of 1957 recommended decriminalization, leading to the Sexual Offences Act 1967 in England and Wales. In the United States, the landmark Lawrence v. Texas decision (2003) struck down sodomy laws nationwide, but many states had repealed their laws earlier—for example, Illinois decriminalized in 1962. Australia, Canada, and Western European nations gradually decriminalized homosexuality in the 1970s and 1980s, while many parts of Africa, the Middle East, and Asia retained—or still retain—draconian penalties. The fight against criminalization remains a global struggle.

The HIV/AIDS Epidemic

No event shaped the LGBTQ community in the late 20th century more profoundly than the HIV/AIDS crisis. Beginning in the early 1980s, the disease decimated a generation of gay men and quickly spread among marginalized populations, including injection drug users and people of color. Government neglect under President Reagan and widespread stigmatization spurred a new wave of militant activism. Groups like ACT UP (founded in 1987) and the Gay Men’s Health Crisis demanded funding for research, access to treatment, and an end to discrimination. ACT UP's direct action tactics—including the 1988 protest at the Food and Drug Administration—forced the pace of drug approval and changed medical research protocols forever. The epidemic forced the community to organize on an unprecedented scale and led to greater visibility—but also to immense trauma and loss, with hundreds of thousands of deaths in the U.S. alone by the end of the decade.

Fighting for the Right to Love: Marriage and Family

The fight for marriage equality gained traction in the 1990s, despite setbacks like the Defense of Marriage Act (DOMA) in 1996, which federally defined marriage as between a man and a woman. State‑level battles, including Hawaii’s Baehr v. Lewin (1993), which argued that denying same‑sex marriage violated equal protection, and Vermont’s civil union law (2000), laid groundwork for eventual nationwide marriage equality. The movement for adoption rights, parental recognition, and family protections also advanced, though not without fierce opposition. By the end of the century, several countries, including the Netherlands (2001), had legalized same‑sex marriage, signaling a global shift.

Legacy and Lessons

Documenting the Past, Securing the Future

The documentation of LGBTQ history in the 20th century is a record of the resilience of a community that refused to be silenced. Archives such as the ONE National Gay & Lesbian Archives at the University of Southern California, the Gerber/Hart Library and Archives in Chicago, and the Keio University LGBTQ Archive in Japan preserve letters, photographs, organizational records, and oral histories that would otherwise be lost. These collections remind us that LGBTQ people have always existed, loved, and organized—even when written out of mainstream narratives. Digital initiatives like the GLBT Historical Society in San Francisco further expand access.

Intersectionality and Inclusivity

One of the most important lessons from 20th‑century LGBTQ history is the importance of intersectionality. The early movement was often dominated by white, middle‑class, gay men, leading to the exclusion of lesbians, transgender people, people of color, and working‑class individuals. Activists like Marsha P. Johnson, Sylvia Rivera, and later figures such as Audre Lorde and Barbara Smith insisted that race, class, gender, and sexuality are inseparable. The Combahee River Collective, a Black feminist lesbian organization, published a landmark statement in 1977 that laid out the theory of intersectionality. Ensuring that history—and current activism—reflects this complexity is key to building a truly equitable movement.

Ongoing Struggles and Future Directions

While the 20th century brought monumental progress, full equality remains elusive. Homosexuality is still criminalized in over 60 countries, and transgender individuals face increasing legislative attacks in parts of the United States and beyond. The documentation of past struggles provides not only inspiration but also strategic lessons: the power of storytelling, the necessity of coalition building, and the need for persistent pressure on institutions. As we move further into the 21st century, preserving and teaching this history is not just an act of remembrance—it is a tool for continued liberation. It is a living record that guides new generations of activists in the ongoing fight for justice.
