The 1471 papal conclave (6–9 August) elected Pope Sixtus IV following the death of Pope Paul II. With the exception of the conclaves of the Western Schism, this conclave was the first since 1305 to feature a working, two-thirds majority of Italians within the College of Cardinals, in no small part because of the absence of six non-Italian cardinals. This was in part due to the unexpectedness of the death of Paul II.
