Which king murered thomas becket?

Thomas Becket was murdered in 1170, and the king associated with his death is King Henry II of England. Although Henry did not order the murder directly, his frustration with Becket's opposition to royal authority led to four knights interpreting his Words as a directive to eliminate the Archbishop of Canterbury. The knights acted on their own, resulting in Becket's assassination in Canterbury Cathedral. This event had significant repercussions for the relationship between church and state in England.
