Which english king established a new justice system that included courts and juries?

The seeds of the modern justice system were sown by Henry II (1154-1189), who established a jury of 12 local knights to settle disputes over the ownership of land. When Henry came to the throne, there were just 18 judges in the country – compared to more than 40,000 today.

The Assize of Clarendon was an act of Henry II of England in 1166 that began a transformation of English law and led to trial by jury in common law countries worldwide, and that established assize courts.

King Henry ll

Explanation:

Before the introduction of the new law on the justice system included courts and juries  which was established by King Henry ll, there was no unified national legal system, each region in England had  their own oral customary laws and rules. Every region or county had a local court that served justices according to their local customs.

The justice system that included courts and juries started as a customary law used by the king's court to settle conflicts and quarrels between monarchs. Even after the Norman inversion, there were still different forms of courts in the different regions and counties.

It was during the reign of King Henry ll that the justice system of courts and juries was established in 1154. He established the common law by creating a unified court system by combining the local courts from the different regions  and counties  to make it one unified jury system.
