Why did Henry II want clerics accused of crimes to face royal punishment?

King Henry II sought to subject "criminous clerks"—members of the clergy accused of serious crimes—to royal punishment primarily because he believed that clerical crime was widespread and that the leniency of ecclesiastical courts encouraged such behavior.123

During the reign of his predecessor, King Stephen, church courts had expanded their judicial reach, often providing punishments that were significantly milder than those of secular courts; clerics found guilty in these courts could be degraded or exiled but were not subject to death or mutilation. Henry II viewed this as an administrative and authoritarian issue, arguing that the absence of more severe penalties failed to deter criminal activity.12

To address this, Henry issued the Constitutions of Clarendon in 1164, which aimed to restore what he defined as the ancient customs of the realm. Clause 3 of these constitutions specifically demanded that clerics convicted of serious felonies in church courts be handed over to royal courts for secular punishment. While Henry’s motives were rooted in a desire to consolidate royal authority and restore order, his efforts were met with fierce opposition from Thomas Becket, who argued that such measures violated church law.132
