Charlamagne and the Roman Catholic Church were on good terms
with each other. He fought and defeated
other groups and converted them to Christianity. That relationship was further strengthen when
Pope Leo III fled from Rome in 799 A.D. and asked for his help to restore him. On Christmas Day, he crowned “Emperor of the
Romans” by the pope. This made him the
first Emperor of Western Europe and with the support of the Church, his rule
flourished. He also strengthened the
spiritual power of the Church and in turn gained the support of the clergy.
