Charlemagne united Western Europe with other European regions after the Roman Empire. During his ruling, the Carolingian Renaissance was fostered within the Church. French and German monarchies viewed themselves as descendants of Charlemagne's empire. The support Charlemagne gave to the Church, made the Pope consider him as a legitimate Roman Emperor.
Charlemagne united the Germanic people under one kingdom. After Charlemagne unified the Germanic people he sought to spread Christianity throughout his kingdom. Charlemagne was a defender of Christianity and gave money, protection and land to the Christian church. HE provided additional support for the church by strengthening the hierarchical structure of the church, clarifying the powers of its officials and improving intellectual and moral quality of the clergy. In return Pope Leo III crowned Charlemagne emperor of the Romans on December 25, 800 at St. Peter's Basilica in Rome. This relationship was mutually beneficial. The church received financial support and had its standing in society legitimized. The church helped Charlemagne to unify the Germanic people under a common religion and the positive press he received from the church helped to strengthen his public perception.
