Pope Urban III
Pope Urban III died at Ferrara on 20 October 1187, only a month after having escaped from Verona, where he was being besieged by Frederick Barbarossa. He was buried in the Cathedral. The Conclave to elect his successor began (and ended) on the next day with the election of Cardinal Alberto di Morro, who took the name Pope Gregory VIII. He left Ferrara for Rome on November 16, and died at Pisa on 17 December 1187.
