Trans studies emerged in the 1990s from a pressing intellectual and political tension: how to study trans lives without reproducing the pathologizing frameworks of medicine, psychiatry, and mainstream feminism that had long defined trans people as disordered, inauthentic, or deviant. The field’s earliest frameworks shared a commitment to centering trans experience and knowledge, but they soon faced a second tension—whose trans experience was being centered? This internal challenge drove the field to expand, diversify, and sharpen its analytical tools, producing a landscape of frameworks that remain in productive disagreement today.
The first wave of trans studies took shape around three frameworks that emerged together in the 1990s: Transfeminism, Transgender History, and Transgender Theory. Each addressed a different dimension of the same problem—the exclusion and misrepresentation of trans people—and each complemented the others without fully overlapping.
Transfeminism linked trans liberation to broader feminist critiques of patriarchy. Rather than treating trans women as intruders in feminist spaces, transfeminist thinkers argued that the same gender hierarchy that oppresses cis women also targets trans people, and that feminism must therefore include trans struggles. This framework coexisted with earlier feminist theories but transformed them by insisting that gender oppression cannot be understood without attending to the specific violence directed at trans bodies.
Transgender History developed as a methodological school focused on recovering erased trans pasts from archives. Where earlier historical work had either ignored trans people or treated them as anomalies, transgender historians showed that trans lives have been documented across cultures and centuries—from female husbands to early twentieth-century gender nonconforming communities. This framework did not replace transfeminism but provided an evidentiary foundation for trans studies, demonstrating that trans existence is not a recent invention.
Transgender Theory responded to a different interlocutor: queer theory. In the 1990s, queer theory had powerfully challenged fixed identities and normative sexuality, but trans theorists argued that it often neglected the material realities of trans bodies and the lived experience of gender transition. Susan Stryker famously called transgender studies “queer theory’s evil twin,” capturing the sense of a sibling field that shared queer theory’s anti-normative impulse but insisted on the specificity of trans embodiment. Transgender Theory thus narrowed queer theory’s scope by demanding attention to the physical, medical, and institutional conditions that shape trans lives—conditions that queer theory’s emphasis on performativity and fluidity sometimes obscured.
Together, these three frameworks built the infrastructure of trans studies. They were not in competition; they were different tools for the same project. But they were largely developed by white, Western, middle-class scholars and drew primarily on U.S. and European examples. That limitation soon became the target of the next wave.
By the early 2000s, a new set of frameworks emerged to challenge the implicit universalism of the 1990s foundations. Intersectional Trans Studies, Decolonial Trans Studies, and Global Trans Studies each responded to the same critique: that early trans studies had centered a narrow slice of trans experience—white, Western, and often middle-class—and had not adequately accounted for how race, colonialism, and geography shape trans lives.
Intersectional Trans Studies applied the insights of Black feminist intersectionality to trans experience. It argued that trans people are not simply oppressed on the basis of gender identity; they also face racism, classism, and other systems of power that interact in specific ways. This framework directly challenged Transgender Theory’s earlier focus on gender as the primary axis of analysis, insisting that a trans woman of color experiences a different kind of marginalization than a white trans man. Intersectional Trans Studies did not reject the earlier frameworks but pluralized them, demanding that trans studies attend to the compounding effects of multiple identities.
Decolonial Trans Studies took the critique in a different direction. It argued that the gender binary itself was imposed through European colonialism, and that pre-colonial societies often recognized third genders or non-binary roles. This framework revived and transformed earlier decolonial feminist thought, linking trans liberation to the broader project of decolonization. Where Transgender History had recovered trans pasts within Western archives, Decolonial Trans Studies insisted that the very categories of “trans” and “cis” are products of colonial modernity and may not travel neatly across cultures.
Global Trans Studies expanded the geographic scope of the field by comparing trans identities, movements, and legal regimes across the world. It criticized the earlier frameworks for treating the U.S. and Western Europe as the default context, and it developed methods for studying trans lives in Asia, Africa, Latin America, and the Middle East without imposing Western categories. This framework coexists with Decolonial Trans Studies but is distinct: Global Trans Studies emphasizes transnational comparison and the circulation of ideas, while Decolonial Trans Studies focuses on the historical violence of colonialism and the recovery of pre-colonial alternatives.
These three 2000s frameworks did not replace the 1990s foundations. Instead, they narrowed the field’s earlier claims to universality and transformed trans studies into a more self-critical, internally diverse enterprise. Today, all six frameworks remain active, and their relationships are best understood as a living disagreement about what trans studies should prioritize.
What do the leading frameworks agree on? Nearly all trans studies scholars share a commitment to centering trans voices, challenging pathologizing medical models, and treating trans experience as a source of knowledge rather than a problem to be solved. There is also broad agreement that trans studies must attend to power—whether through feminism, intersectionality, or decolonial critique.
But significant disagreements persist. One ongoing tension is between Transgender Theory and Intersectional Trans Studies: the former tends to foreground gender identity as the primary axis of analysis, while the latter insists that race, class, and other structures are equally constitutive and cannot be added on as an afterthought. Another disagreement concerns the role of the state: some scholars argue for legal recognition and medical access as crucial gains, while others warn that state recognition can produce new forms of exclusion, such as transnormativity—the privileging of binary, medically transitioned, and normatively gendered trans people over those who are non-binary, poor, or gender nonconforming. Decolonial and Global Trans Studies further complicate these debates by questioning whether Western frameworks of rights and identity should be exported at all.
The field today is not a single theory but a landscape of interconnected approaches, each with its own strengths and blind spots. Transgender History continues to provide the empirical depth that grounds trans studies; Transgender Theory offers conceptual tools for analyzing embodiment and identity; Transfeminism remains a vital political bridge to feminist movements; and the three 2000s frameworks keep the field honest about its exclusions. The central tension that launched trans studies—how to study trans lives without reproducing harm—has not been resolved, but it has been deepened and enriched by the frameworks that followed.
