After Henry II became king in 1154, standard laws were written down, meaning there was a uniform legal system across the whole country for the first time
Betraying your lord and joining rebellion against a king had been crimes in Anglo-Saxon times, but William I pushed these crimes much more harshly to try to assert his authority
William I ordered the death penalty for the rebels themselves, and also punished those who were not directly involved in the rebellions, resulting in 100,000 people starving to death due to the destruction of farmland
Throughout medieval times there was no official 'police force', and the community was largely responsible for both preventing crime and catching criminals
Around the year 1000, most people lived in small hamlets, farms, villages or a few small towns, and this tight-knit community structure helped keep the crime rate fairly low
Throughout the medieval period, the Church was extremely powerful and played a direct role in deciding what constituted a crime, how the accused was tried, and what punishments were handed out
Church courts tried members of the clergy for all crimes, and many laymen memorised Bible passages to claim this benefit and receive more lenient punishments
