High Quality Content by WIKIPEDIA articles! John Paul I (Latin: Ioannes Paulus PP. I, Italian: Giovanni Paolo I), born Albino Luciani, (17 October 1912 – 28 September 1978), reigned as Pope of the Catholic Church and as Sovereign of Vatican City from 26 August 1978 until his death 33 days later. His reign is among the shortest in papal history, resulting in the most recent Year of Three Popes. John Paul I was the first Pope to be born in the 20th century, and was also the last Pope to die in it.
