Bourbon, Charles de, styled the Constable de Bourbon, acquired immense wealth by the death of an elder brother and by his marriage, and lived in royal state; was for his daring in the field named Constable of France by Francis I.; offended at some, perhaps imaginary, injustice Francis did him, he clandestinely entered the service of the Emperor Charles V., defeated the French at Pavia, and took Francis captive; parted from Charles, laid siege to Rome, and fell in the assault, mortally wounded, it is said, by Benvenuto Cellini (1489‒1527).
