What was the Inquisition in Roman Catholicism?
The Inquisition in Roman Catholicism was a bureaucratically organized tribunal of clergy, sometimes including laymen, whose goal was to discover and eliminate unorthodox religious opinions and practices in Christian Europe from the 15th to 19th centuries.
The Spanish Inquisition, the largest and best known, was established in 1478 by Pope Sixtus IV at the request of Ferdinand and Isabella. Later, inquisitions were established in Portugal (1540) and Rome (1542). The inquisitions aimed to supervise the moral failings of the clergy and laity, and combat Protestantism, which was viewed as heresy in Catholic territories.
The inquisitions recruited officials systematically and followed well-defined legal procedures. They worked in secrecy, which led to speculation and fictionalization of their activities. Those accused of heresy who refused to recant were handed over to secular authorities and burned at the stake, although the inquisitors' chief aim was to reconcile heretics to the church.

Why was the Inquisition created?
The Inquisition was created to combat what the Roman Catholic Church defined as heresy, particularly Protestantism. The Spanish Inquisition, requested by Ferdinand and Isabella, aimed to detect crypto-Judaism among Jewish converts to Christianity and to eradicate Protestant Christianity.
All inquisitions had the authority to supervise the moral conduct of both clergy and laity. The Roman Inquisition, established in 1542, specifically aimed to combat Protestantism within Catholic territories. These inquisitions were characterized by well-defined legal procedures, systematic recruitment of officials, and a vertical command structure.

Who were the main people involved in the Inquisition?
The individuals involved in the Inquisition varied depending on the specific time period and location.
Key people involved in the Inquisition:
* Pope Lucius III Required bishops to make inquiries regarding heresy in their dioceses in 1184.
* Pope Gregory IX Appointed the first judges delegate as inquisitors for heretical depravity in 1227.
* Tomás de Torquemada As the first grand inquisitor in Spain, he reorganized the Spanish Inquisition and influenced policies against Jewish and Islamic converts. He promulgated articles for inquisitors, authorized torture, and was involved in the expulsion of Jews from Spain.
* Ferdinand and Isabella The rulers of Aragon and Castile who requested Pope Sixtus IV to establish the Spanish Inquisition.
* Francisco, Cardinal Jim\u00e9nez de Cisneros As grand inquisitor, he promoted the suppression of Muslims, ordering the proscription of Islam in Granada.4 Britannica SourcesThis answer is created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles. -
How did the Inquisition investigate and judge people?
During an inquisition, an inquisitor started an inquiry in a district, announcing a period of grace for voluntary confessions of heresy, which resulted in light penances. Confessions helped compile suspect lists, and those who failed to appear were considered guilty.
Trials involved the inquisitor, a notary, and sworn witnesses. Suspects often didn't know the charges against them or who made them and had no lawyer. Judgments occurred after consulting canon lawyers at a sermo generalis, or public homily. Punishments included pilgrimages, wearing yellow crosses, and imprisonment. Those who didn't recant were burned.
The Spanish Inquisition shared similarities with the medieval inquisition in procedure. The first grand inquisitor in Spain, Tomás de Torquemada, became known for brutality. Sentencing of the accused occurred at the auto-da-fé, a public display of the Inquisition’s power.

What were some punishments given by the Inquisition?
The Inquisition employed various punishments for individuals found guilty of heresy. Those who voluntarily confessed and identified other heretics often received lighter penances during a period of grace.
Judicial penances were imposed on those convicted of heresy who recanted, with common punishments including:
* Penitential pilgrimages
* Wearing yellow crosses on clothing, leading to ostracism
* Imprisonment in either open prisons (murus largus) or high-security prisons (murus strictus)Heretics who refused to recant were handed over to secular authorities and burned at the stake, though the primary goal of the inquisitors was to reconcile heretics with the Church. The Spanish Inquisition aimed to consolidate the authority of the Spanish monarchy through violence and terror. The Roman Inquisition combatted Protestantism, which was considered a heresy in Catholic territories.

How did the Inquisition affect European society and history?
The Inquisition significantly impacted European society and history through its pursuit of religious uniformity and the suppression of heresy. Established tribunals, such as the Spanish Inquisition, aimed to detect and eliminate heterodox religious opinions and practices.
The Inquisition instilled terror through secret procedures, acceptance of denunciations, and the use of torture, which led to social division and spying. The obsession with "purity of blood" (limpieza de sangre) in Spain led to discrimination and had a blighting effect on Spanish society.
Conversely, the Inquisition contributed to the supervision of moral behavior, and, uniquely, a disinclination to participate in witch hunts. It also led to the censorship of books and isolation of Spanish intellectual life.

inquisition, a judicial procedure and later an institution that was established by the papacy and, sometimes, by secular governments to combat heresy. Derived from the Latin verb inquiro (“inquire into”), the name was applied to commissions in the 13th century and subsequently to similar structures in early modern Europe.
The Middle Ages
History
In 1184 Pope Lucius III required bishops to make a judicial inquiry, or inquisition, for heresy in their dioceses, a provision renewed by the fourth Lateran Council in 1215. Episcopal inquisitions, however, proved ineffective because of the regional nature of the bishop’s power and because not all bishops introduced inquisitions in their dioceses; the papacy gradually assumed authority over the process, though bishops never lost the right to lead inquisitions. In 1227 Pope Gregory IX appointed the first judges delegate as inquisitors for heretical depravity—many, though not all, of whom were Dominican and Franciscan friars. Papal inquisitors had authority over everyone except bishops and their officials. There was no central authority to coordinate their activities, but after 1248 or 1249, when the first handbook of inquisitorial practice was written, inquisitors adopted common procedures.
In 1252 Pope Innocent IV licensed inquisitors to allow obdurate heretics to be tortured by lay henchmen. It is difficult to determine how common this practice was in the 13th century, but the inquisition certainly acquiesced in the use of torture in the trial of the Knights Templar, a military-religious order, in 1307. Persecution by the inquisition also contributed to the collapse of Catharism, a dualist heresy that had great influence in southern France and northern Italy, by about 1325; although established to defeat that heresy, the inquisition was assisted by the pastoral work of the mendicant orders in its triumph over the Cathars.
The inquisition declined in importance in the late Middle Ages, though it continued to try cases of heresy—e.g., the Waldenses, the Spiritual Franciscans, and the alleged heresy of the Free Spirit, a supposed sect of mystics who advocated antinomianism—and cases of sorcery. The most vigorous dissenting movements of the 15th century, Lollardy in England and Hussitism in Bohemia, were not subject to its jurisdiction.
Procedures and organization
When instituting an inquiry in a district, an inquisitor would normally declare a period of grace during which those who voluntarily confessed their own involvement in heresy and that of others would be given only light penances. The inquisitor used these confessions to compile a list of suspects whom he summoned to his tribunal. Failure to appear was considered evidence of guilt. The trial was often a battle of wits between the inquisitor and the accused. The only other people present were a notary, who kept a record of the proceedings, and sworn witnesses, who attested the record’s accuracy. No lawyer would defend a suspect for fear of being accused of abetting heresy, and suspects were not normally told what charges had been made against them or by whom. The accused might appeal to the pope before proceedings began, but this involved considerable expense.
After consulting with canon lawyers, the inquisitor would sentence those found guilty at a sermo generalis, or public homily. Judicial penances were imposed on those who had been convicted of heresy and had recanted. The most common punishments were penitential pilgrimages, the wearing of yellow crosses on clothing (which was feared because it led to ostracism), and imprisonment.
The inquisition employed two kinds of prisons, both staffed by laymen. One type was the murus largus, or open prison, which consisted of cells built around a courtyard in which the inmates enjoyed considerable freedom. The other type was the murus strictus, a high-security prison, where inmates were kept in solitary confinement, often in chains. Heretics who admitted their errors but refused to recant were handed over to the secular authorities and burned at the stake. There were usually not many cases of this kind, because the chief aim of the inquisitors was to reconcile heretics to the church. On rare occasions, however, large public executions did take place, as at Verona in 1278, when some 200 Cathars were burned.
Although heresy was a capital offense in virtually all the states of western Europe, some rulers—for example, the kings of Castile and England—refused to license the inquisition. Even where it did operate—in much of Italy and in kingdoms such as France and Aragon—the inquisition relied entirely on the secular authorities to arrest and execute those whom it named and to defray all its expenses. The money came partly from the sale of the confiscated property of convicted heretics.
Although some scholars have denied that the medieval inquisition was an institution, others maintain that it is the best way to describe a group of men who enjoyed the same powers, were directly responsible to the pope, employed servants and officials, and had absolute control over a number of large prisons and their inmates. Nevertheless, its power was very limited, and, arguably, it was important chiefly because it established a tradition of religious coercion in the late medieval Western church that was inherited by both Catholics and Protestants in the 16th century.
