Final answer:
Charlemagne's reign was marked by constant warfare for conversion and loot, reformation of the Church and education, and attempts to revive Roman institutions and culture through the Carolingian Renaissance.
Step-by-step explanation:
Aside from dealing with the Franks, one of the key priorities and focuses of Charlemagne during his reign was the reformation of education and the church.
Consistently waging wars and seeking to convert non-Christian Europeans to Christianity were significant aspects of his rule. Moreover, he was dedicated to the idea of resurrecting the Roman Empire as a Christian state guided by Germanic leaders.
This endeavor, known as the Carolingian Renaissance, included reorganizing the government and attempting to revive learning through the promotion of classical studies, the correction of flawed versions of the Vulgate, and sponsoring the creation of libraries and education for priests.
