The 1389 conclave (25 October – 2 November) was convoked after the death of Pope Urban VI. The conclave is historically unique because all of the cardinal electors were the creation of a single pontiff: Urban VI, the very pope who was being replaced. None of the surviving cardinals created by previous popes recognized Urban VI as legitimate (see: Western Schism). In addition, Urban VI had deposed four of his creatures, and three were absent, leaving only sixteen cardinal electors.Miranda, Salvator. 1998. "Papal elections of the 14th Century (1303–1394)."
