Question

what was the forced religion by charlemagne? islam christianity hindu judaism

Explanation:

Charlemagne, also known as Charles the Great, was a devout Christian. He played a significant role in spreading and enforcing Christianity within his empire. He engaged in military campaigns against non - Christian groups (such as the Saxons) and often imposed conversion to Christianity as a condition for peace or integration into his realm. Islam was the religion of the Arab Muslims who were at times in conflict with Charlemagne's Frankish Empire. Hinduism is the major religion of the Indian subcontinent, far from Charlemagne's European domain. Judaism was a minority religion in Europe during that time but was not the religion that Charlemagne was forcing.

Answer:

Christianity
