Evolution of Legal Systems from Ancient Codes to Cybercrime Legislation

The Code of Ur-Nammu, developed around 2100-2050 BCE in Mesopotamia, is one of the earliest known law codes, predating Hammurabi's by centuries. It prescribed fines, not corporal punishment, for most offenses.

Roman law introduced the concept of legal entities like corporations and the notion of 'innocent until proven guilty'. The Twelve Tables, Rome’s first codification of law, influenced modern legal systems considerably.

Medieval justice often relied on 'trial by ordeal', where the accused underwent dangerous tests to prove innocence. Surprisingly, acquittals were common, as clergy administering the ordeals manipulated outcomes to prevent deaths.

The Enlightenment spurred reforms and the birth of classical criminal theory. Cesare Beccaria's 1764 work 'On Crimes and Punishments' condemned torture and death penalty, advocating for a rational justice system.

The 19th century saw the rise of penitentiaries, like Eastern State in the US, designed to reform rather than punish. Isolation and labor aimed to rehabilitate, but often led to mental deterioration.

Today's systems emphasize rehabilitation over retribution, with varying success. Norway's recidivism rate is under 30%, attributed to humane prison conditions and focus on social reintegration of offenders.

The digital age introduced cybercrime, necessitating new laws and enforcement strategies. The first computer crime legislation was the Computer Fraud and Abuse Act (CFAA), passed in the United States in 1986.
