Clement VII. (Giulio de' Medici) was a cousin of Leo X., and was elected pope in 1523, having previously been Archbishop of Florence and Cardinal. He allied himself with Francis I. of France and the Republic of Venice against the Emperor Charles V., with the result that the Imperialists under the Constable of Bourbon sacked Rome in 1527. He resisted the divorce scheme of Henry VIII. of England and in 1534 issued his famous bull against that monarch, dying in the same year.
