The Roman Inquisition was a system of tribunals developed by the Holy See of the Roman Catholic Church during the second half of the 16th century, responsible for prosecuting individuals accused of a wide array of crimes relating to religious doctrine or alternate religious beliefs. In the period after the Medieval Inquisition, it was one of three different manifestations of the wider Christian Inquisition along with the Spanish Inquisition and Portuguese Inquisition.
Like other iterations of the Inquisition, the Roman Inquisition was responsible for prosecuting individuals accused of committing offences relating to heresy, including Protestantism, sorcery, immorality, blasphemy, Judaizing and witchcraft, as well as for censorship of printed literature.
The tribunals of the Roman Inquisition covered most of the Italian peninsula as well as Malta and also existed in isolated pockets of papal jurisdiction in other parts of Europe, including Avignon in France. The Roman Inquisition, though, was considerably more bureaucratic and focussed on pre-emptive control in addition to the reactive judicial prosecution experienced under other iterations.
Typically, the pope appointed one cardinal to preside over meetings of the Congregation. Though often referred to in historical literature as Grand Inquisitors, the role was substantially different to the formally appointed Grand Inquisitor of the Spanish Inquisition. There were usually ten other cardinals who were members of the Congregation, as well as a prelate and two assistants all chosen from the Dominican Order. The Holy Office also had an international group of consultants; experienced scholars of theology and canon law who advised on specific questions. The congregation, in turn, presided over the activity of local tribunals.
In 1588, Pope Sixtus V established 15 congregations of the Roman Curia of which the Supreme Sacred Congregation of the Roman and Universal Inquisition was one. In 1908, the congregation was renamed the Supreme Sacred Congregation of the Holy Office and in 1965 it was renamed again and is now known as the Congregation for the Doctrine of the Faith.
While the Roman Inquisition was originally designed to combat the spread of Protestantism in Italy, the institution outlived that original purpose and the system of tribunals lasted until the mid 18th century, when pre-unification Italian states began to suppress the local inquisitions, effectively eliminating the power of the church to prosecute heretical crimes.
In 1616, the Roman Inquisition's consultants gave their assessment of the proposition that the sun is immobile and at the center of the universe and that the Earth moves around it, judging both to be "foolish and absurd in philosophy" and that the first was "formally heretical" while the second was "at least erroneous in faith".
Galileo Galilei revised those same theories and was also admonished for his views on heliocentrism. In 1633, the Roman Inquisition tried Galileo and found him "vehemently suspected of heresy" and banned Galileo's Dialogue Concerning the Two Chief World Systems.
Among the subjects of this Inquisition were Franciscus Patricius, Giordano Bruno, Tommaso Campanella, Gerolamo Cardano, Cesare Cremonini, and Galileo Galilei. Of these, only Bruno was executed; Galileo died under house arrest, and Campanella was imprisoned for twenty-seven years. The miller Domenico Scandella was also burned at the stake on the orders of Pope Clement VIII in 1599 for his belief that God was created from chaos.
17th century traveller and author, John Bargrave, gave an account of his interactions with the Roman Inquisition. Arriving in the city of Reggio (having travelled from Modena), Bargrave was stopped by the city guard who inspected his books on suspicion some may have been on the Index Librorum Prohibitorum. Bargrave was brought before the city's chief inquisitor who suggested they converse in Latin rather than Italian so that the guards might be prevented from understanding them. The inquisitor told him that the inquisition were not accustomed to stopping visitors or travellers unless someone had suggested they do so (Bargrave suspected that Jesuits in Rome had made accusations against him). Nonetheless, Bargrave was told he was required to hold a license from the inquisition. Even with a license, Bargrave was prohibited from carrying any books, "printed at any heretical city, as Geneva, Amsterdam, Leyden, London, or the like". Bargrave provided a catalogue of his books to the inquisition and was provided with a license to carry them for the rest of his journey.
The Inquisition in Malta (1561 to 1798) is generally considered to have been gentler.
Later history 
The last notable action of the Roman Inquisition occurred in 1858, in Bologna, when Inquisition agents legally removed a 6-year-old Jewish boy, Edgardo Mortara, from his family. The local inquisitor had learned that the boy was secretly baptised by his nursemaid. Pope Pius IX raised the boy as a Catholic in Rome. The boy's father, Momolo Mortara, spent years seeking help in all quarters, including internationally, to try to reclaim his son. The case received international attention and fueled the anti-papal sentiments that helped the Italian nationalism movement and culminated in the 1870 Capture of Rome.
