The French kings after Charles VIII – Louis XII, Francis I, Henry II and Francis II – also continued to use imperial titles and honors. Like his predecessor Charles VIII, Louis XII also invaded Italy, as part of the Second Italian War (1499–1504), and during this time presented himself as a would-be crusader ostensibly headed for Constantinople and Jerusalem. The effigy of Louis XII on his grave bears an imperial crown, rather than a royal one. Francis I publicly stressed his claim to be the Emperor of Constantinople as late as 1532. Not until Charles IX in 1566 did the imperial claim come to an eventual end through the rules of extinctive prescription as a direct result of desuetude, or lack of use. Charles IX wrote that the imperial Byzantine title "is not more eminent than that of a king, which sounds better and sweeter".
