Philip IV of France
His final year saw a scandal amongst the royal family, known as the Tour de Nesle affair, in which Philip's three daughters-in-law were accused of adultery. His three sons were successively kings of France: Louis X, Philip V, and Charles IV. Their rapid successive deaths without surviving sons of their own would compromise the future of the French royal house, which had until then seemed secure, precipitating a succession crisis that would eventually lead to the Hundred Years' War (1337–1453).
