What impact did Charlemagne have on in the Frankish kingdom?

Charlemagne, also known as Charles the Great, had a profound impact on the Frankish kingdom by unifying much of Western Europe under his rule, effectively expanding the territory and influence of the Frankish Empire. He promoted the Carolingian Renaissance, fostering a revival of art, culture, and learning by encouraging the establishment of schools and the preservation of classical texts. His coronation as Emperor of the Romans in 800 AD symbolized the merging of Roman, Christian, and Germanic traditions, laying the groundwork for the future Holy Roman Empire. Additionally, his reforms in administration and governance strengthened the central authority of the monarchy, contributing to the development of feudalism in medieval Europe.
