About This Topic

The legal history of LGBTQ+ rights in the United States is a story of significant change compressed into roughly 50 years. In 1986, the Supreme Court upheld state sodomy laws in Bowers v. Hardwick; by 2015, it recognized a constitutional right to same-sex marriage in Obergefell v. Hodges. Understanding this trajectory requires students to examine the legal strategies that advocates used: challenging laws on equal protection and due process grounds, building on civil rights precedents, and carefully sequencing cases to shift judicial opinion over time.

This topic gives 12th graders an opportunity to apply constitutional concepts from the broader unit in a concrete, historically recent context. Students study the arguments in Romer v. Evans (1996), Lawrence v. Texas (2003), United States v. Windsor (2013), and Obergefell (2015), tracing how each decision built on the last. They also examine remaining legal debates, including religious liberty conflicts and employment discrimination protections established in Bostock v. Clayton County (2020).

Active learning methods work especially well here because the topic involves weighing competing constitutional values and interpreting relatively recent primary sources. When students must read both majority opinions and dissents and argue from the text rather than from personal views, they develop the analytical distance that constitutional analysis requires.

Before You Start

Foundations of American Democracy

Why: Students need a basic understanding of the U.S. Constitution, including the Bill of Rights and the structure of the federal government, to comprehend legal arguments.

The Civil Rights Movement (1950s-1960s)

Why: Understanding the strategies, legal precedents, and social impact of the Black Civil Rights Movement provides essential context for the LGBTQ+ rights movement's legal approach.

Key Vocabulary

Equal Protection Clause	A constitutional guarantee that all individuals within a jurisdiction are afforded the same rights and protections under the law, often cited in civil rights litigation.
Due Process Clause	A constitutional guarantee that the government cannot deprive any person of life, liberty, or property without fair legal procedures, another key argument in civil rights cases.
Stare decisis	The legal principle of determining points in litigation according to precedent, meaning courts should follow previous rulings when making decisions.
Substantive due process	A legal principle that protects certain fundamental rights from government interference, even if fair procedures are followed, which has been applied to rights like marriage.
Religious Freedom Restoration Act (RFRA)	A federal law, and similar state laws, that prohibits government agencies from substantially burdening a person's exercise of religion, a point of contention in LGBTQ+ rights cases.

Watch Out for These Misconceptions

Common Misconception

Same-sex marriage was always the inevitable outcome of LGBTQ+ litigation.

What to Teach Instead

Advocates pursued marriage recognition strategically and not without setbacks. Bowers v. Hardwick (1986) was a significant loss. Legal organizations sometimes cautioned against bringing marriage cases too early, fearing unfavorable precedent would set the movement back. The eventual victory reflects deliberate strategy, not inevitability.

Common Misconception

LGBTQ+ rights issues are fully settled after Obergefell.

What to Teach Instead

Active litigation continues on questions including transgender rights in schools and the military, the scope of religious exemptions from anti-discrimination laws, and access to gender-affirming healthcare. Obergefell resolved the question of same-sex marriage; many other questions remain contested in courts and legislatures.

Common Misconception

Equal protection and substantive due process arguments are basically the same.

What to Teach Instead

Equal protection asks whether a law treats similarly situated people differently without adequate justification. Substantive due process asks whether a law violates a fundamental liberty interest. Courts have used both frameworks in LGBTQ+ cases, sometimes in the same opinion, but they analyze different constitutional questions and require different legal showings.

Case Progression Analysis: Building the Legal Argument

Small groups each receive one case from the sequence (Bowers, Romer, Lawrence, Windsor, Obergefell) and identify the central legal argument and ruling. Groups present in chronological order, and the class maps how each decision altered the legal landscape for the next case. This makes the strategic logic of the litigation campaign visible.

Real-World Connections

• Attorneys at organizations like Lambda Legal and the ACLU utilize case law from the LGBTQ+ rights movement to litigate employment discrimination cases for clients in states with varying levels of legal protection.
• Lobbyists and policymakers in Washington D.C. analyze the historical legal strategies of the LGBTQ+ movement to draft and advocate for new legislation, such as the Equality Act, or to defend existing rights.
• Judges at all levels of the federal court system must interpret and apply precedents set by landmark LGBTQ+ rights cases, such as Obergefell v. Hodges, when ruling on contemporary legal disputes.

Assessment Ideas

Discussion Prompt

Pose the question: 'How did the legal strategy of building on previous civil rights precedents influence the outcomes of key LGBTQ+ rights cases?' Facilitate a class discussion where students cite specific cases and legal arguments to support their points.

Quick Check

Provide students with short excerpts from majority opinions and dissents in Romer v. Evans and Lawrence v. Texas. Ask them to identify one core argument from each excerpt and explain how the arguments differ, using a graphic organizer.

Exit Ticket

On an index card, have students write one sentence explaining the significance of *Bostock v. Clayton County* for employment protections and one sentence predicting a future legal challenge for LGBTQ+ rights.

Frequently Asked Questions

What legal strategy did LGBTQ+ rights advocates use to win Supreme Court cases?

Advocates built a deliberate litigation strategy that sequenced cases to establish favorable precedent incrementally. Early cases targeted criminal laws (Lawrence), then discriminatory state constitutional amendments (Romer), then federal marriage law (Windsor), and finally state marriage bans (Obergefell). Each victory created a stronger constitutional foundation for the next challenge.

Does federal law protect LGBTQ+ employees from workplace discrimination?

Yes. In Bostock v. Clayton County (2020), the Supreme Court held that Title VII of the Civil Rights Act of 1964, which prohibits sex discrimination in employment, covers discrimination based on sexual orientation and gender identity. The Court reasoned that discriminating against someone for being gay or transgender necessarily involves treating them differently because of their sex.

What is the current state of religious liberty exemptions from anti-discrimination laws?

This is an active area of litigation. The Court addressed conflicts between anti-discrimination laws and religious objections in Masterpiece Cakeshop (2018) and 303 Creative (2023), generally finding narrow grounds to rule without resolving the broader tension. The balance between free exercise rights and anti-discrimination protections remains unsettled.

How does active learning help students analyze the LGBTQ+ rights movement?

Reading and mapping competing legal arguments in pairs or small groups helps students separate their personal views from constitutional analysis, a critical civic skill. When students must articulate the strongest version of arguments they may personally disagree with, they develop the kind of reasoning that serious constitutional analysis demands.
