For much of early American legal history, young people could be processed through systems closely resembling those used for adults. Reform movements during the nineteenth century increasingly argued that children were developmentally different from adults and that the justice system should emphasize rehabilitation rather than simply punishment.

The nation's first juvenile court was established in Cook County, Illinois, in 1899. The emerging juvenile court system was heavily influenced by parens patriae — the principle that the government could act protectively in the interests of children. Early juvenile proceedings were intentionally informal, which was believed to permit judges to focus upon the needs and circumstances of individual children rather than replicating adult criminal court procedures.

The approach, however, created another problem: youth could face serious consequences without receiving many of the procedural protections afforded to adults. The Supreme Court's landmark decision in In re Gault in 1967 substantially changed juvenile justice. The Court recognized important due-process protections in delinquency proceedings capable of producing confinement, including notice of allegations, counsel, confrontation of witnesses, and protections involving self-incrimination.

Modern juvenile systems vary considerably among states, particularly concerning age boundaries, detention, transfer to adult court, and available dispositions. They nevertheless generally preserve a conceptual distinction between juvenile delinquency and adult criminal prosecution.

Students should also understand specialized terminology. Juvenile courts frequently use adjudication rather than conviction and disposition rather than sentencing. Diversion describes mechanisms that may redirect eligible youth away from formal judicial processing while still providing accountability, intervention, or services.

The juvenile justice system therefore reflects a continuing tension among several goals: accountability, rehabilitation, public safety, child development, due process, victim interests, and prevention of future offending. That tension makes juvenile justice one of the most important interdisciplinary subjects in criminal justice.
