Source-derived summary

Pope Victor III (c. 1026 – 16 September 1087), born Dauferio Epifani Del Zotto, was the head of the Catholic Church and ruler of the Papal States from 24 May 1086 to his death. He was the successor of Pope Gregory VII. Prior to becoming pope he had held the important post of abbot of the great monastery of Montecassino, under his monastic name of Desiderius and during those years played a historically important role.

He is the most recent lawfully elected pope to have taken the pontifical name "Victor".

In contrast with his early public life, as Pope Victor, as he had become, he made a less significant contribution. His failing health was the chief factor that made him so reluctant to accept election as pope and that his health was in fact seriously impaired was clear when he fell ill during the ceremony of his coronation as pope.

Family

Daufer was born in c. 1026. The Catholic Encyclopedia states his father died in 1047 in battle. He obtained permission to enter the monastery of St.

For this dossier, Pope, Victor and head is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “head of the Catholic Church and ruler of the Papal States from 1086 to 1087” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Critical limits

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
