Charlemagne
Charlemagne (742-814), which means Charles the Great, was King of the Franks and Holy Roman Emperor, rising to rule over most of Europe during his lifetime. The third ruler in the Carolingian Dynasty, he inherited his kingdom from his father, Pepin III, in 768 and gained complete control after the death of his brother Carloman in 771. In 800, he was crowned Holy Roman Emperor by Pope Leo III in Rome.
Early rule
In accordance with Frankish tradition, upon his death Pepin III in 768, divided the kingdom between his two sons, Charles and his younger brother Carloman. The three year period in which both brothers ruled was marked with internal conflict. At the urging of his mother, Bertrada, Charles married Desiderata in 770, daughter of the Lombard king Desiderius. This alliance surrounded Carloman's territories between Charles and Lombardy, which led to a brief reconciliation between the brothers. Charles felt constrained by his alliances, and in a sudden move divorced his wife in 771 and married a Frankish woman named Hildegard. This was an insult to Desiderius and the threat of an alliance with Carloman to invade Charles' kingdom loomed. This threat was neutralized in December 771, when Carloman suddenly died at the age of 20. Carloman's former vassals and allies quickly proclaimed their allegiance to Charles, and he became the sole ruler over the Frankish kingdom.
