What was one result of Charlemagne's reign in terms of cultural influence?

The establishment of a unified Christian curriculum during Charlemagne's reign had significant cultural influence across Europe. Charlemagne recognized the importance of education for the governance of his empire, which led to the promotion of learning and the establishment of schools throughout his realm. This included the standardization of religious education, which was rooted in Christian theology and practice, helping to foster a shared cultural and intellectual framework among the diverse populations within his empire.

Under his rule, the Carolingian Renaissance emerged, which was characterized by a revival of art, culture, and learning based on classical and Christian sources. Monastic schools became centers of education where not only the clergy but also laypeople could receive an education grounded in Christian teachings. This initiative not only helped preserve classical texts during a turbulent period in European history but also contributed to the formation of a more cohesive European identity rooted in Christianity.

In contrast, other options such as a decline of literacy, isolation of regions, or expansion of paganism do not align with the historical impact of Charlemagne's policies. His reign is generally associated with the opposite trends—fostering literacy, promoting unity, and diminishing pagan practices in favor of Christianity.
