Which 1166 legal reform under Henry II strengthened royal justice and is linked to juries of presentment?

The story behind the answer

Issued in 1166 by Henry II, this measure ordered local communities to swear in “juries of presentment” (twelve from each hundred and four from each township) to name suspected criminals under oath. It expanded royal oversight by directing sheriffs to arrest suspects, seize their goods, and bring them before traveling royal justices, with the accused often subjected to the ordeal. The policy centralized criminal justice, weakened private baronial courts, and professionalized investigation and prosecution.

It also seeded key features of the common law: communal inquest, standardized procedure across shires, and the ancestor of the modern grand jury. By contrast, the Constitutions of Clarendon (1164) targeted church courts, the Assize of Northampton (1176) updated penalties and enforcement, and the Charter of Liberties (1100) was a coronation pledge, not a criminal-justice overhaul.
