Source-derived summary

Pope Clement X (Latin: Clemens X; Italian: Clemente X; 13 July 1590 – 22 July 1676), born Emilio Bonaventura Altieri, was head of the Catholic Church and ruler of the Papal States from 29 April 1670 to his death on 22 July 1676.

Emilio Bonaventura Altieri, born in Rome in 1590, belonged to the Papal nobility. He received a doctorate in law and held various positions within the Catholic Church, including Bishop of Camerino and Superintendent of the Papal Exchequer. At the age of almost 80, he was elected Pope Clement X in 1670 after a four-month-long conclave. As Pope, he canonized and beatified various saints, promoted good relations between Christian countries, and made efforts to preserve the Altieri family name by adopting the Paoluzzi family. He also established a new tax in Rome, which led to conflicts with ambassadors and cardinals. Clement X celebrated the fourteenth jubilee of the holy year in 1675 despite his old age. During his pontificate, he created 20 cardinals, including Pietro Francesco Orsini, who later became Pope Benedict XIII.

He suspended the Portuguese Inquisition's proceedings in October 1674, challenging the techniques employed against its main victims, the New Christians.

Early life

Emilio Bonaventura Altieri was born in Rome in 1590, the son of Lorenzo Altieri and Vittoria Delfin, a noble Venetian lady. His brother was Cardinal Giambattista Altieri.

Editorial reviewA valuable geographic starting point for tracing changing names, boundaries, uses and administrative responsibility. The current lead gives the account dated anchors—1590, 1676, 1670, 1675—that can be checked directly. The linked authority record independently contributes the date 1590-07-13. Its value is orientation rather than verdict, with Pope, Clement and pope providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Pope Clement X”, the useful work is to connect “pope of the Catholic Church from 1670 to 1676 (1590-1676)” to the records capable of establishing context and consequence.

Evidence profile

The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q155956. VIAF identifies the subject as 316874496. The Library of Congress control number is n85310847. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1590, 1676, 1670 and 1675.

Critical limits

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. 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.
