Clement, faced with a deplete college of cardinals, created thirty-one cardinals over three years, the most since Hadrian IV. He died 20 March 1191 and was quickly replaced by Celestine III.

Pope Alexander III, born Roland, was head of the Catholic Church and ruler of the Papal States from 7 September 1159 until his death in 1181.
