Who divorced Henry VIII and Catherine of Aragon?

There were quite a few people that refused to accept King Henry VIII's divorce from Queen Catherine of Aragon.

Among the most notable were Cardinal Campeggio and Pope Clement VII at the time, who caused quite a delay in the separation.

Thomas Cranmer eventually became archbishop under King Henry's rule and declared the marriage invalid (just in time for Anne Boleyn and King Henry to be married and conceive a child).

King Henry was later excommunicated from the church. Thereby establishing himself as the head of the Church of England - still in place to this day.
