Source-derived summary

Pope Honorius IV (born Giacomo Savelli; c. 1210 — 3 April 1287) was head of the Catholic Church and ruler of the Papal States from 2 April 1285 to his death on 3 April 1287. His election followed the death of Pope Martin IV and was notable for its speed; he was chosen unanimously on the first ballot. Honorius IV's papacy occurred during a tumultuous period marked by political strife and conflict in Sicily, where he sought to navigate complex relationships with various rulers while maintaining papal authority. During his pontificate he continued to pursue the pro-French political policy of his predecessor. He is the most recent pope to take the pontifical name "Honorius" upon election, after his granduncle Pope Honorius III.

Early life and education

Giacomo Savelli was born in Rome into the rich and influential Savelli family. His father, Luca Savelli, was a senator of Rome who died in 1266. His mother Joanna belonged to the Aldobrandeschi family.

Savelli studied at the University of Paris, and held a prebend and a canonry at the cathedral of Châlons-sur-Marne. Later he obtained the benefice of rector at the church of Barton Mills in Suffolk, England, although he never visited the country.

Career

In 1261, he was created Cardinal Deacon of Santa Maria in Cosmedin by Pope Urban IV, who also appointed him papal prefect in Tuscany and captain of the papal army.

Editorial summary

This brief starts where responsible research should: with the source description of “Pope Honorius IV” as pope of the Catholic Church from 1285 to 1287. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA strong orientation record where physical form, institutional use and historical geography need to be read together. The current lead gives the account dated anchors—1210, 1287, 1285, 1266—that can be checked directly. The linked authority record independently contributes the date 1210. The account is most persuasive where Pope, Honorius and pope can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the places & architecture register because the source frames it as pope of the Catholic Church from 1285 to 1287. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jun 16, 2026. The linked authority identifier is Q227743. VIAF identifies the subject as 95191011. The Library of Congress control number is nb2007017853. 3 of 4 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1210, 1287, 1285 and 1266.

Critical limits

Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. 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.
