Habitual offender laws — the legal predecessors to modern three-strikes sentencing — did not originate in the 1990s crime policy debates where they are commonly situated. A 2025 Sentencing Project report traces their origins to the early twentieth-century eugenics movement, which used long incarceration as a mechanism for preventing reproduction among people deemed genetically inferior. By the mid-twentieth century, 42 states had enacted habitual offender laws reflecting this ideology. Despite the discrediting of eugenics after World War II, 49 states and the federal government maintain some form of repeat-offender sentencing enhancement today. The structural logic of these laws — that certain people present a permanent social danger requiring extended removal from society — was never formally repudiated. It was repackaged.
Eugenics and the Birth of Habitual Offender Laws
Eugenics — the pseudo-scientific movement that sought to improve the human population through selective reproduction — was not a fringe ideology in early twentieth-century America. It was a mainstream intellectual and political program, supported by universities, promoted by prominent scientists and politicians, and embedded in law through legislative campaigns that operated across multiple states simultaneously.
Eugenicists believed that traits they characterized as social deficiencies — mental illness, physical disability, poverty, criminality, and behaviors associated with specific racial and ethnic groups — were hereditary and could be eliminated from the population through careful management of who reproduced. Their policy agenda had two primary instruments: surgical sterilization, which directly prevented reproduction, and long incarceration, which accomplished the same goal by removing targeted individuals from the reproductive population for extended periods.
Habitual offender laws were the carceral instrument of this program. By imposing extended sentences on individuals convicted of multiple offenses, these laws could achieve population control without requiring the explicit acknowledgment that reproduction prevention was the objective. The sentence was structured as a crime control measure. The effect was eugenic.
In 1927, the Supreme Court decided Buck v. Bell, upholding Virginia’s compulsory sterilization law. Justice Oliver Wendell Holmes, writing for the majority, concluded that the state’s interest in preventing the reproduction of the “unfit” was sufficient to justify forced sterilization. The decision provided constitutional cover for eugenics programs across the country. American eugenics laws — including those upheld under Buck v. Bell — were subsequently cited by Nazi legal architects as models for German racial hygiene programs. The Nuremberg trials exposed what that ideology produced at scale. Buck v. Bell has never been formally overruled by the Supreme Court. It remains on the books.
The Legislative Spread
The Sentencing Project’s 2025 report documents that habitual offender laws spread through deliberate legislative campaigns, not through organic policy responses to local crime conditions. Model legislation, advocacy organizations explicitly promoting eugenic goals, and networks of legislators who understood the reproductive control function of these statutes drove adoption across 42 states by mid-century.
The populations targeted by these laws tracked the populations eugenicists had identified as genetically inferior. People with criminal records were explicitly categorized as genetically deficient. The racial dimension of this targeting was not incidental — eugenicists believed the traits they associated with criminality were concentrated in specific racial and ethnic communities, and their legislative advocacy reflected that belief in both the design of the laws and their enforcement.
The formal discrediting of eugenics following World War II did not produce a legislative reckoning with the laws eugenics had created. Most habitual offender statutes were not repealed. They were allowed to remain in effect, separated from their ideological origins by the passage of time and by the political reframing that repositioned them as responses to crime rather than instruments of population control.
The 1990s Repackaging
The “three strikes” laws that became prominent in the 1990s were presented as a new policy response to rising crime rates — a tough-on-crime innovation of that political moment. The Sentencing Project’s report challenges this framing. The structural logic of three-strikes sentencing — that a person’s prior convictions demonstrate a permanent disposition toward criminal behavior requiring extended incarceration — is the same logic that drove habitual offender legislation in the eugenics era. What changed in the 1990s was not the theory but the political language used to justify it.
The 1994 federal crime bill and the wave of state three-strikes laws that followed drew on the existing habitual offender framework that had been in place for decades. They expanded it, made it mandatory in new contexts, and attached it to new political constituencies. But they did not create it. They inherited it — along with the disproportionate racial impact that had been a feature of the framework since its eugenic origins, not a bug that developed later.
The Sentencing Project’s report documents that 49 states and the federal government maintain some form of repeat-offender sentencing enhancement today. These laws continue to produce the disproportionate impact on Black communities and communities of color that their structural logic was designed to produce. Reforming individual statutes without confronting the eugenic logic embedded in the concept of permanent criminal dangerousness leaves the foundational problem intact. Understanding the history is not merely an academic exercise. It is a prerequisite for reform that actually addresses what these laws are rather than what they claim to be.
What Reform Requires
Reform of habitual offender laws requires acknowledging what the Sentencing Project’s research documents: these statutes were not originally crime control measures. They were population control measures. Any reform process that treats these laws as neutral crime policy in need of technical adjustment rather than as eugenics-derived frameworks in need of fundamental reexamination will produce inadequate results. The history is the starting point, not an interesting footnote.
The disproportionate application of habitual offender laws to Black communities and communities of color is not an implementation problem that better training or oversight can correct. It reflects the structural targeting built into these laws from their eugenic origins. Reform frameworks that treat disparate impact as an unintended consequence rather than as a structural feature will fail to address the actual problem. Meaningful reform requires confronting what the laws were designed to do and evaluating whether any reconfiguration of that design can produce equitable results.
The Sentencing Project’s report supports the case for reevaluating rather than merely reforming habitual offender laws. Amendments to statutes whose structural logic is eugenic — graduated sentence reductions, expanded discretion, or narrowed application — operate within a framework that the underlying theory makes coherent in ways that resist incremental change. Repeal, followed by replacement with sentencing frameworks designed from different premises and evaluated against their actual outcomes, is the more honest policy path.
Buck v. Bell‘s continued status as unreversed precedent is not merely a historical anomaly. It leaves on the books a Supreme Court ruling that the state’s interest in preventing the reproduction of those it deems unfit is constitutionally sufficient to justify forced bodily intervention. That holding underlies the entire legal framework within which eugenic sentencing laws operated. A Court that formally rejected Buck v. Bell would remove one structural foundation of the eugenic legal architecture — and would force an honest accounting of what remains.
The history of habitual offender laws is not a story that ended when eugenics was discredited. It is a story with an active present: 49 states and the federal government administering sentencing frameworks whose conceptual origins were never confronted, whose disproportionate impact was never addressed at its source, and whose structural logic — that certain people are permanently dangerous and must be removed from society — remains embedded in American criminal law. Understanding where these laws came from is the beginning of understanding what it would actually take to change them.
