Brief Explanations:

Charlemagne promoted learning and education. He established schools, brought in scholars, and encouraged the preservation and copying of ancient texts. This had a long - lasting positive impact on the intellectual and cultural life of Europe. He did not allow free - choice of religion as Christianity was the dominant and often enforced religion during his time. While he had a relationship with the Church, increasing its power was not the main way he improved people's lives. Strengthening commerce was not his most well - known contribution compared to his efforts in education.

Answer:

He revived education.
