Pope Innocent XVII, born Francisco Calderano (5 June 1880 - 30 September 1967) was the pope from June 13, 1940 until his death in 1967, reigning over 27 years. He is regarded as one of the most influential popes in contemporary history and was given sainthood in 1991. He was the second-longest reigning pope after Pius IX, and ruled the Papal States first alongside the Bravanatti family and later as the absolute, albeit comparatively benign, authority in most of Italy.
