Louis V left no legitimate heirs, so his uncle Charles, Duke of Lower Lorraine, was nominated as the hereditary successor to the throne. But the clergy, including both Adalberon and Gerbert (who later became Pope Sylvester II), argued eloquently for the election of Hugh Capet, who was not only of royal blood but had proven himself through his actions and his military might. Hugh was elected to the Frankish throne and Adalberon crowned him, all within two months of Louis V's death. Thus the rule of the Carolingian dynasty ended and the Capetian era had begun.
