Once in power, Charlemagne sought to unite all the Germanic peoples into one kingdom, and convert his subjects to Christianity. In order to carry out this mission, he spent the majority of his reign engaged in military campaigns. Soon after becoming king, he conquered the Lombards (in present-day northern Italy), the Avars (in modern-day Austria and Hungary) and Bavaria, among others.

Charlemagne waged a bloody, three-decades-long series of battles against the Saxons, a Germanic tribe of pagan worshippers, and earned a reputation for ruthlessness. In 782 at the Massacre of Verden, Charlemagne reportedly ordered the slaughter of some 4,500 Saxons. He eventually forced the Saxons to convert to Christianity, and declared that anyone who didn’t get baptized or follow other Christian traditions be put to death
