Why the modern criminal justice system is a relatively recent human invention

In short: For most of history, crime was a private affair settled by families or local vendettas. It was only in the late 18th century that humanitarian reformers began questioning the cruelty of penal systems, eventually shifting the focus from retribution toward the scientific study of crime, prevention, and human rights.

Before the rise of formal state institutions, justice was often a personal matter. In Ancient Greece and Rome, even severe crimes like murder were handled by the victim's family through private wars or vendettas. While early civilizations like Egypt established police forces as early as the Fifth Dynasty, these were often military-linked units tasked with protecting public spaces rather than investigating individual crimes. In Ancient China, a more structured prefecture system emerged, where officials managed law enforcement, though the system was frequently plagued by corruption, with officers occasionally accepting bribes or forming social networks with the criminals they were meant to apprehend.

The modern academic and systemic approach to criminal justice began in the late 18th century. Influenced by humanitarian ideals, reformers like Cesare Beccaria, John Howard, and Jeremy Bentham challenged the arbitrary and cruel nature of existing prison systems. Their classical school of thought aimed to humanize penal institutions and ensure due process, famously advocating for the principle of nulla poena sine lege. However, their focus remained largely on retribution and deterrence, often ignoring the specific needs or personal characteristics of the individual defendant.

By the 19th century, the field evolved toward scientific inquiry. Adolphe Quetelet, a Belgian statistician, pioneered the use of crime statistics, discovering surprising regularities in criminal behavior across age, gender, and conviction rates. This laid the groundwork for modern criminology, which now incorporates diverse disciplines like sociology, psychology, and anthropology. Today, the field has expanded to include criminalistics—the scientific detection of crime through DNA and toxicology—and victimology, which examines the role and experience of the victim in the criminal event, marking a significant departure from the purely retributive models of the past.
