How did Clovis and Charlemagne help spread Christianity?

A:The Frankish king Clovis I (481-511), a devout pagan, converted to Catholic Christianity, thus strengthening the position of the Catholic Church. Christian kings demanded that their subjects also be Christians.

Charlemagne used conquests, tyranny and bloodshed to spread Christianity. Kathleen Jefferts Schori, presiding bishop of the U.S. Episcopal Church, said, "Charlemagne converted whole tribes by the sWord." In the year 782, the Frankish king Charlemagne reputedly beheaded forty-five hundred Saxons who resisted his campaign of forced conversion to Christianity. In 800, the Pope crowned Charlemagne in Rome, as Holy Roman Emperor.
