1. Centralization of justice: Henry II established royal courts and itinerant justices who traveled throughout the kingdom to hear cases. This centralized the administration of justice and made it more consistent, which reduced the power of local lords and increased the authority of the king.
2. Common law: Henry II's system of justice also led to the development of common law, which was a body of law that was based on past precedents and applied throughout the kingdom. This made the law more predictable and fair, which encouraged people to seek justice in the royal courts rather than through private means.
3. Juries: Henry II introduced the use of juries in criminal cases. Juries were made up of local people who were sworn to give a verdict based on the evidence presented in court. This gave ordinary people a voice in the administration of justice and further reduced the power of local lords.
4. Royal revenue: The royal courts generated revenue for the king through fees and fines. This increased the king's financial resources and made him less dependent on the support of his barons.
5. Strengthened royal authority: By centralizing justice, developing common law, using juries, and generating revenue, Henry II's innovative system of justice contributed to the growth of the royal system and helped to make the king the supreme authority in England.
