King Henry and Thomas Becket were very good friends; and Henry made Thomas his counsellor
Henry thought that the kings courts weren't doing very well and made Thomas the Archbishop of Canterbury.
Thomas took his job seriously and stopped getting drunk and wearing fancy clothes; and treated the people properly. Thomas then fled to France for 6 years because him and Henry had a fall out; because Thomas wasn't doing the job how Henry wanted it to be done.
Thomas came back to Britain; Thomas and Henry worked together in the church and tried to make it equal but it went wrong again.
Henry got 4 soldiers to kill Thomas because Henry was fed up with Thomas not doing what he wanted.
