Pope Saint Celestine V (c. 1215 – 19 May 1296), born Pietro Angelerio (according to some sources Angelario, Angelieri, Angelliero, or Angeleri), also known as Pietro da Morrone, was elected pope in the year 1294, by the Papal election, 1292–1294, the last non-conclave in the history of the Roman Catholic Church.
