The papal election of 24 May 1086 ended with the election of Desiderus, abbot of Monte Cassino as Pope Gregory VII's successor after a year-long period of sede vacante.
The archdiocese was a vacant see following the death of Archbishop Joseph Serge Miot, who was one of the many casualties of the 12 January 2010 earthquake when the Archdiocesan Chancery building collapsed.
