Final answer:
The conflict between Henry II and Thomas Becket over ecclesiastical jurisdiction ended with Becket's martyrdom in 1170, after which he was canonized and Henry performed penance, leading to a compromise on church and royal jurisdiction.
Step-by-step explanation:
Henry II's six-year conflict with his archbishop, Thomas Becket, over whether churchmen were to submit to royal courts concluded tragically.
The conflict ended with the martyrdom of Thomas Becket in 1170, after four knights, believing they were acting on Henry's wishes, murdered Becket in Canterbury Cathedral. Shortly after Becket's death, he was canonized as a saint, and Henry had to do penance to appease the public and the church.
This event led to a compromise where the church retained ecclesiastical authority over clergy but allowed for some royal jurisdiction in certain legal matters. The conflict greatly influenced the relationship between the church and the state in England, serving as a precedent for future monarchs, including Henry's descendants, who would seek to establish greater control over religious matters within their kingdom.
