Pope Pius III (d. 1503)
Pope Pius III (Italian: Pio III; 9 May 1439 – 18 October 1503), born Francesco Todeschini, was head of the Catholic Church and ruler of the Papal States from 22 September 1503 to his death. At just twenty-six days, he had one of the shortest pontificates in papal history.Francesco was the nephew of Pope Pius II, who granted him the use of the family name "Piccolomini", and appointed the twenty-one-year old Francesco as Archbishop of Siena. He served as papal legate in a number of places. In 1503, the now-frail Cardinal Piccolomini was elected pope as a compromise candidate between the Borgia and della Rovere factions. Although he announced plans for reforms, he died less than a month later.
