The Roman Inquisition was founded in 1542 as the Supreme Sacred Congregation of the Roman and Universal Inquisition to defend Catholic doctrine and prosecute heresy within the Papal States and across much of the Italian peninsula. It was created by Pope Paul III through the bull Licet ab initio on 21 July 1542 and staffed by a commission of six cardinals as a central tribunal in Rome with supervisory authority over local inquisitorial courts.

Origins and institutional development
- –Establishment (1542): Licet ab initio formed a permanent congregation of cardinals to “watch over matters of faith,” inaugurating what contemporaries called the Sant’Uffizio.
Vatican – Dicastery Profile.
- –Expansion under Paul IV: From 1555 the papacy extended the Inquisition’s remit to a wider range of moral and doctrinal questions, strengthening its reach amid the Catholic response to the Reformation.

- –Tridentine era and Curial reform: Sixtus V’s Immensa aeterni Dei (1588) fixed the Inquisition as a major congregation of the Roman Curia, embedding it in the post–Council of Trent governance of the Church.
- –Later name changes: Pius X reorganized the body as the Sacred Congregation of the Holy Office (1908), and Paul VI, by the motu proprio Integrae servandae (7 December 1965), retitled it the Congregation for the Doctrine of the Faith; in 2022, Pope Francis’ constitution Praedicate Evangelium renamed it the Dicastery for the Doctrine of the Faith.

Organization, jurisdiction, and seat
- –Central tribunal: The Roman congregation of cardinals acted as a supreme court for heresy cases, supervising local inquisitors (often Dominican friars) and coordinating procedure and appeals.
- –Geographic scope: Tribunals operated throughout the Papal States and in many Italian polities; in the Republic of Venice, an Inquisition existed under close civil oversight from 1547/1551 until 1797.
- –Seat and archives: The central office was housed at the Palazzo del Sant’Uffizio near St. Peter’s; the archive (Archivio del Sant’Uffizio), long closed, was opened to qualified scholars in 1998 for materials up to 1903.

Procedure and penalties
- –Process: Proceedings typically began with denunciations, followed by preliminary inquiry, arrest where warranted, interrogation, and consultation of theologians and canonists; sentences ranged from admonitions and abjurations to spiritual penances, fines, imprisonment, and, in obstinate cases, delivery to secular authority for capital punishment.

Black, The Italian Inquisition](book://Christopher F. Black|The Italian Inquisition|Yale University Press|2009).
- –Regulation of torture and evidence: Roman practice was governed by canon-law limits, requiring indicia of guilt, recording of confessions, and restrictions on reiteration; sentencing emphasized reconciliation when possible.

Censorship and the Index Librorum Prohibitorum
- –Index and book control: The Inquisition supervised doctrinal censorship; in 1571 Pius V created a separate Congregation for the Index, though the Holy Office remained pivotal in doctrinal judgments.
- –Chronology and abolition: The first Roman Index appeared in 1559; a revised Tridentine Index followed in 1564; the Index’s legal force was suppressed in 1966, though it retained advisory status.
Notable cases and doctrinal controversies
- –Giordano Bruno (1548–1600): After extradition from Venice, Bruno’s long Roman trial ended with condemnation as an impenitent heretic and execution by secular authorities in Rome on 17 February 1600.
- –Galileo Galilei (1564–1642): In 1616, the Congregation of the Index, acting on consultation by the Holy Office, suspended Copernicus’ work “until corrected” and prohibited texts defending heliocentrism; in 1633 Galileo was tried by the Roman Inquisition and sentenced to imprisonment (commuted to house arrest) for “vehement suspicion of heresy.”

Personnel and papal oversight
- –Papal supervision and grand inquisitors: The pope presided over the congregation, delegating to leading cardinals; future popes such as Pius V played central roles as inquisitorial officials before their pontificates.
Transformation and continuity
- –1908 and 1965 reforms: Pius X retitled the congregation the Holy Office (Sapienti consilio), streamlining Curial competencies; Paul VI’s Integrae servandae aligned it with a modern emphasis on promoting doctrine rather than primarily policing it.
- –2022 reorganization: Praedicate Evangelium renamed the office the Dicastery for the Doctrine of the Faith and detailed its doctrinal and disciplinary sections, confirming institutional continuity with the historic Roman Inquisition.
- –Archival access and scholarship: Opening of the Sant’Uffizio archives in 1998 facilitated modern research on procedures, regional variations, and case files, reshaping historiography on the Italian Inquisition.
Historiography
- –Scholarship emphasizes the Roman Inquisition’s legalistic procedure, supervisory centralization in Rome, and its integration with civic authorities in Italian states; punishments often aimed at reconciliation, with severity focused on obstinate or relapsed offenders.
