In page Anselm of Canterbury:

"

Even after this, Anselm refused to return to England.[11] Henry travelled to Bec and met with him on 15 August 1106. Henry was forced to make further concessions. He restored to Canterbury all the churches that had been seized by William or during Anselm's exile, promising that nothing more would be taken from them and even providing Anselm with a security payment. Henry had initially taxed married clergy and, when their situation had been outlawed, had made up the lost revenue by controversially extending the tax over all churchmen.[12] He now agreed that any prelate who had paid this would be exempt from taxation for three years. These compromises on Henry's part strengthened the rights of the Church against the king. Anselm returned to England before the new year.[1]
