The Juvenile Court Act of 1899 created the first juvenile court in Cook County, Illinois (Chicago). This marked the beginning of a separate legal system for minors, distinguishing them from adult offenders and focusing on rehabilitation rather than punishment. This model influenced the development of juvenile courts across the country.

In 1966, the U.S. Supreme Court ruled in In re Gault that juveniles have constitutional rights, including the right to due process, the right to be notified of charges, the right to an attorney, and the right to confront witnesses. This landmark decision significantly expanded the legal protections for juveniles in the justice system.

The Juvenile Justice and Delinquency Prevention Act of 1974 (JJDPA) was passed by Congress to promote reforms in the juvenile justice system. The act required states to take steps to deinstitutionalize juveniles, especially for status offenses (non-criminal behavior like truancy), and to separate juvenile offenders from adult inmates. It also aimed to reduce racial and ethnic disparities in the system.

During the 1980s and 1990s, there was a significant shift toward more punitive policies in juvenile justice, spurred by rising concerns over juvenile crime, especially violent crime. Many states passed laws making it easier to transfer juveniles to adult courts, and "zero-tolerance" policies became more common. This period saw an increase in juvenile incarceration rates, though critics argued that these approaches were ineffective and harmful to youth.

In 2005, the U.S. Supreme Court ruled in Roper v. Simmons that it is unconstitutional to impose the death penalty on individuals who were under 18 at the time of their offense. The Court cited the developmental differences between juveniles and adults, as well as the possibility of rehabilitation, as reasons for its decision. This ruling was a significant step toward recognizing the unique status of juveniles in the justice system.

In 2012, the U.S. Supreme Court ruled in Miller v. Alabama that mandatory life sentences without the possibility of parole for juveniles convicted of murder are unconstitutional. The Court emphasized that juvenile offenders are less culpable than adults and should have the opportunity for rehabilitation. This ruling further cemented the principle that juveniles are different from adults in terms of both legal treatment and punishment.
