Henry II

The conflict between King Henry II and Thomas Becket primarily stemmed from Henry’s efforts to reassert royal authority over the church and limit ecclesiastical independence.12
The tension culminated in the Constitutions of Clarendon (1164), a set of articles designed to restrict church privileges. Key points of disagreement included:1
- Jurisdiction over "criminous clerks": The most contentious issue was Henry’s demand that clerics who committed serious crimes be punished in royal courts after an initial trial in church courts.12
- Royal Control: Henry sought to require royal consent for clerics leaving the realm or making judicial appeals to Rome, and he claimed revenues from vacant sees and monasteries.1
- Legal Authority: Disputes arose over church patronage, land tenure, and the church's power to excommunicate or interdict without royal approval.1
- Coronation Rights: Tensions escalated when Henry had his son crowned by the archbishop of York, violating the traditional right of the archbishop of Canterbury to perform the ceremony.23
Becket, once a close ally of the king, became a staunch defender of ecclesiastical supremacy, leading to his exile and eventual martyrdom.23
