What was the relationship between charlemagne or charles the great and the roman chatholic church?

The Carolingians came from a long line of bishops, religious leaders in the Roman Catholic Church, so Charles was loyal to the church. He defended the Pope in Rome when needed and had a famous campaign against the Saxons.  He cut the sacred oak trees of the Saxons and made lumber to build churches.

he believed that strong monarchies would lead to social and political stability.
