Inquisition
The Inquisition was a group of institutions within the Catholic Church whose aim was to combat heresy, conducting trials of suspected heretics. Studies of the records have found that the overwhelming majority of sentences consisted of penances, but convictions of unrepentant heresy were handed over to the secular courts, which generally resulted in execution or life imprisonment. The Inquisition had its start in the 12th-century Kingdom of France, with the aim of combating religious deviation (e.g. apostasy or heresy), particularly among the Cathars and the Waldensians. The inquisitorial courts from this time until the mid-15th century are together known as the Medieval Inquisition. Other groups investigated during the Medieval Inquisition, which primarily took place in France and Italy, include the Spiritual Franciscans, the Hussites, and the Beguines. Beginning in the 1250s, inquisitors were generally chosen from members of the Dominican Order, replacing the earlier practice of using local clergy as judges.During the Late Middle Ages and the early Renaissance, the scope of the Inquisition grew significantly in response to the Protestant Reformation and the Catholic Counter-Reformation. During this period, the Inquisition conducted by the Holy See was known as the Roman Inquisition. The Inquisition also expanded to other European countries, resulting in the Spanish Inquisition and the Portuguese Inquisition. The Spanish and Portuguese Inquisitions were instead focused particularly on the New Christians or Conversos, as the former Jews who converted to Christianity to avoid antisemitic regulations and persecution were called, the anusim (people who were forced to abandon Judaism against their will by violence and threats of expulsion) and on Muslim converts to Catholicism. The scale of the persecution of converted Muslims and converted Jews in Spain and Portugal was the result of suspicions that they had secretly reverted to their previous religions, although both religious minority groups were also more numerous on the Iberian Peninsula than in other parts of Europe, as well as the fear of possible rebellions and armed uprisings, as had occurred in previous times.
During this time, Spain and Portugal operated inquisitorial courts not only in Europe, but also throughout their empires in Africa, Asia, and the Americas. This resulted in the Goa Inquisition, the Peruvian Inquisition, and the Mexican Inquisition, among others.With the exception of the Papal States, the institution of the Inquisition was abolished in the early 19th century, after the Napoleonic Wars in Europe and the Spanish American wars of independence in the Americas. The institution survived as part of the Roman Curia, but in 1908 it was renamed the Supreme Sacred Congregation of the Holy Office. In 1965, it became the Congregation for the Doctrine of the Faith.  In 2022, this office was renamed the Dicastery for the Doctrine of the Faith.

Definition and purpose
The term "Inquisition" comes from the Medieval Latin word inquisitio, which described any court process based on Roman law, which had gradually come back into use during the Late Middle Ages. Today, the English term "Inquisition" can apply to any one of several institutions that worked against heretics (or other offenders against canon law) within the judicial system of the Roman Catholic Church. Although the term "Inquisition" is usually applied to ecclesiastical courts of the Catholic Church, it refers to a judicial process, not an organization. Inquisitors '...were called such because they applied a judicial technique known as inquisitio, which could be translated as "inquiry" or "inquest".' In this process, which was already widely used by secular rulers (Henry II used it extensively in England in the twelfth century), an official inquirer called for information on a specific subject from anyone who felt he or she had something to offer."The Inquisition, as a church-court, had no jurisdiction over Muslims and Jews as such. Generally, the Inquisition was concerned only with the heretical behaviour of Catholic adherents or converts.The overwhelming majority of sentences seem to have consisted of penances like wearing a cross sewn on one's clothes or going on pilgrimage. When a suspect was convicted of unrepentant heresy, canon law required the inquisitorial tribunal to hand the person over to secular authorities for final sentencing. A secular magistrate, the "secular arm", would then determine the penalty based on local law. Those local laws included proscriptions against certain religious crimes, and the punishments included death by burning, although the penalty was more usually banishment or imprisonment for life, which was generally commuted after a few years. Thus the inquisitors generally knew the fate which expected anyone so remanded.The 1578 edition of the Directorium Inquisitorum (a standard Inquisitorial manual) spelled out the purpose of inquisitorial penalties: ... quoniam punitio non refertur primo & per se in correctionem & bonum eius qui punitur, sed in bonum publicum ut alij terreantur, & a malis committendis avocentur (translation: "... for punishment does not take place primarily and per se for the correction and good of the person punished, but for the public good in order that others may become terrified and weaned away from the evils they would commit").

Origin
Before the 12th century, the Catholic Church suppressed what they believed to be heresy, usually through a system of ecclesiastical proscription or imprisonment, but without using torture, and seldom resorting to executions. Such punishments were opposed by a number of clergymen and theologians, although some countries punished heresy with the death penalty. Pope Siricius, Ambrose of Milan, and Martin of Tours protested against the execution of Priscillian, largely as an undue interference in ecclesiastical discipline by a civil tribunal. Though widely viewed as a heretic, Priscillian was executed as a sorcerer. Ambrose refused to give any recognition to Ithacius of Ossonuba, "not wishing to have anything to do with bishops who had sent heretics to their death".In the 12th century, to counter the spread of Catharism, prosecution of heretics became more frequent. The Church charged councils composed of bishops and archbishops with establishing inquisitions (the Episcopal Inquisition). The first Inquisition was temporarily established in Languedoc (south of France) in 1184. The murder of Pope Innocent's papal legate Pierre de Castelnau in 1208 sparked the Albigensian Crusade (1209–1229). The Inquisition was permanently established in 1229 (Council of Toulouse), run largely by the Dominicans in Rome and later at Carcassonne in Languedoc.

Medieval Inquisition
Historians use the term "Medieval Inquisition" to describe the various inquisitions that started around 1184, including the Episcopal Inquisition (1184–1230s) and later the Papal Inquisition (1230s). These inquisitions responded to large popular movements throughout Europe considered apostate or heretical to Christianity, in particular the Cathars in southern France and the Waldensians in both southern France and northern Italy. Other Inquisitions followed after these first inquisition movements. The legal basis for some inquisitorial activity came from Pope Innocent IV's papal bull Ad extirpanda of 1252, which explicitly authorized (and defined the appropriate circumstances for) the use of torture by the Inquisition for eliciting confessions from heretics. However, Nicholas Eymerich, the inquisitor who wrote the "Directorium Inquisitorum", stated: 'Quaestiones sunt fallaces et ineficaces' ("interrogations via torture are misleading and futile"). By 1256 inquisitors were given absolution if they used instruments of torture.In the 13th century, Pope Gregory IX (reigned 1227–1241) assigned the duty of carrying out inquisitions to the Dominican Order and Franciscan Order. By the end of the Middle Ages, England and Castile were the only large western nations without a papal inquisition.
Most inquisitors were friars who taught theology and/or law in the universities. They used inquisitorial procedures, a common legal practice adapted from the earlier Ancient Roman court procedures. They judged heresy along with bishops and groups of "assessors" (clergy serving in a role that was roughly analogous to a jury or legal advisers), using the local authorities to establish a tribunal and to prosecute heretics. After 1200, a Grand Inquisitor headed each Inquisition. Grand Inquisitions persisted until the mid 19th century.

Inquisition in Italy
Only fragmentary data is available for the period before the Roman Inquisition of 1542. In 1276, some 170 Cathars were captured in Sirmione, who were then imprisoned in Verona, and there, after a two-year trial, on February 13 from 1278, more than a hundred of them were burned. In Orvieto, at the end of 1268/1269, 85 heretics were sentenced, none of whom were executed, but in 18 cases the sentence concerned people who had already died. In Tuscany, the inquisitor Ruggiero burned at least 11 people in about a year (1244/1245). Excluding the executions of the heretics at Sirmione in 1278, 36 Inquisition executions are documented in the March of Treviso between 1260 and 1308. Ten people were executed in Bologna between 1291 and 1310. In Piedmont, 22 heretics (mainly Waldensians) were burned in the years 1312-1395 out of 213 convicted.  22 Waldensians were burned in Cuneo around 1440 and another 5 in the Marquisate of Saluzzo in 1510. There are also fragmentary records of a good number of executions of people suspected of witchcraft in northern Italy in the 15th and early 16th centuries.  Wolfgang Behringer estimates that there could have been as many as two thousand executions. This large number of witches executed was probably because some inquisitors took the view that the crime of witchcraft was exceptional, which meant that the usual rules for heresy trials did not apply to its perpetrators. Many alleged witches were executed even though they were first tried and pleaded guilty, which under normal rules would have meant only canonical sanctions, not death sentences. The episcopal inquisition was also active in suppressing witches. alleged witches; in 1518, judges delegated by the Bishop of Brescia, Paolo Zane, sent some 70 witches from Val Camonica to the stake.

Inquisition in France
France has the best preserved archives of the medieval inquisition (13th-14th centuries), although they are still very incomplete. The activity of the inquisition in this country was very diverse, both in terms of time and territory. In the first period (1233 to c. 1330), the courts of Languedoc (Toulouse, Carcassonne) are the most active. After 1330 the center of the persecution of heretics shifted to the Alpine regions, while in Languedoc they ceased almost entirely. In northern France, the activity of the Inquisition was irregular throughout this period and, except for the first few years, it was not very intense.France's first Dominican inquisitor, Robert le Bougre, working in the years 1233-1244, earned a particularly grim reputation. In 1236, Robert burned about 50 people in the area of Champagne and Flanders, and on May 13, 1239, in Montwimer, he burned 183 Cathars. Following Robert's removal from office, Inquisition activity in northern France remained very low. One of the largest trials in the area took place in 1459-1460 at Arras; 34 people were then accused of witchcraft and satanism, 12 of them were burned at the stake.The main center of the medieval inquisition was undoubtedly the Languedoc. The first inquisitors were appointed there in 1233, but due to strong resistance from local communities in the early years, most sentences concerned dead heretics, whose bodies were exhumed and burned. Actual executions occurred sporadically and, until the fall of the fortress of Montsegur (1244), probably accounted for no more than 1% of all sentences. In addition to the cremation of the remains of the dead, a large percentage were also sentences in absentia and penances imposed on heretics who voluntarily confessed their faults (for example, in the years 1241-1242 the inquisitor Pierre Ceila reconciled 724 heretics with the Church). Inquisitor Ferrier of Catalonia, investigating Montauban between 1242 and 1244, questioned about 800 people, of whom he sentenced 6 to death and 20 to prison.  Between 1243 and 1245, Bernard de Caux handed down 25 sentences of imprisonment and confiscation of property in Agen and Cahors. After the fall of Montsegur and the seizure of power in Toulouse by Count Alfonso de Poitiers, the percentage of death sentences increased to around 7% and remained at this level until the end of the Languedoc Inquisition around from 1330. Between 1245 and 1246, the inquisitor Bernard de Caux carried out a large-scale investigation in the area of Lauragais and Lavaur. He covered 39 villages, and probably all the adult inhabitants (5,471 people) were questioned, of whom 207 were found guilty of heresy. Of these 207, no one was sentenced to death, 23 were sentenced to prison and 184 to penance. Between 1246 and 1248, the inquisitors Bernard de Caux and Jean de Saint-Pierre handed down 192 sentences in Toulouse, of which 43 were sentences in absentia and 149 were prison sentences. In Pamiers in 1246/1247 there were 7 prison sentences [201] and in Limoux in the county of Foix 156 people were sentenced to carry crosses. Between 1249 and 1257, in Toulouse, the Inquisition handed down 306 sentences, without counting the penitential sentences imposed during "times of grace". 21 people were sentenced to death, 239 to prison, in addition, 30 people were sentenced in absentia and 11 posthumously; In another five cases the type of sanction is unknown, but since they all involve repeat offenders, only prison or burning is at stake. Between 1237 and 1279, at least 507 convictions were passed in Toulouse (most in absentia or posthumously) resulting in the confiscation of property; in Albi between 1240 and 1252 there were 60 sentences of this type.The activities of Bernard Gui, inquisitor of Toulouse from 1307 to 1323, are better documented, as a complete record of his trials has been preserved. During the entire period of his inquisitorial activity, he handed down 633 sentences against 602 people (31 repeat offenders), including:

41 death sentences,
40 convictions of fugitive heretics (in absentia),
20 sentences against people who died before the end of the trial (3 of them Bernardo considered unrepentant, and his remains were burned at the stake),
69 exhumation orders for the remains of dead heretics (66 of whom were subsequently burned),
308 prison sentences,
136 orders to carry crosses,
18 mandates to make a pilgrimage (17) or participate in a crusade (1),
in one case, sentencing was postponed.In addition, Bernard Gui issued 274 more sentences involving the mitigation of sentences already served to convicted heretics; in 139 cases he exchanged prison for carrying crosses, and in 135 cases, carrying crosses for pilgrimage. To the full statistics, there are 22 orders to demolish houses used by heretics as meeting places and one condemnation and burning of Jewish writings (including commentaries on the Torah).The episcopal inquisition was also active in Languedoc. In the years 1232–1234, the Bishop of Toulouse, Raymond, sentenced several dozen Cathars to death. In turn, Bishop Jacques Fournier of Pamiers in the years 1318-1325 conducted an investigation against 89 people, of whom 64 were found guilty and 5 were sentenced to death.After 1330, the center of activity of the French Inquisition moved east, to the Alpine regions, where there were numerous Waldensian communities. The repression against them was not continuous and was very ineffective. Data on sentences issued by inquisitors are fragmentary. In 1348, 12 Waldensians were burned in Embrun, and in 1353/1354 as many as 168 received penances. In general, however, few Waldensians fell into the hands of the Inquisition, for they took refuge in hard-to-reach mountainous regions, where they formed close-knit communities. Inquisitors operating in this region, in order to be able to conduct trials, often had to resort to the armed assistance of local secular authorities (e.g. military expeditions in 1338–1339 and 1366). In the years 1375–1393 (with some breaks), the Dauphiné was the scene of the activities of the inquisitor Francois Borel, who gained an extremely gloomy reputation among the locals. It is known that on July 1, 1380, he pronounced death sentences in absentia against 169 people, including 108 from the Valpute valley, 32 from Argentiere and 29 from Freyssiniere. It is not known how many of them were actually carried out, only six people captured in 1382 are confirmed to be executed.In the 15th and 16th centuries, major trials took place only sporadically, e.g. against the Waldensians in Delphinate in 1430–1432 (no numerical data) and 1532–1533 (7 executed out of about 150 tried) or the aforementioned trial in Arras 1459–1460 . In the 16th century, the jurisdiction of the Inquisition in the kingdom of France was effectively limited to clergymen, while local parliaments took over the jurisdiction of the laity. Between 1500 and 1560, 62 people were burned for heresy in the Languedoc, all of whom were convicted by the Parliament of Toulouse.Between 1657 and 1659, twenty-two alleged witches were burned on the orders of the inquisitor Pierre Symard in the province of Franche-Comte, then part of the Empire.The inquisitorial tribunal in papal Avignon, established in 1541, passed 855 death sentences, almost all of them (818) in the years 1566–1574, but the vast majority of them were pronounced in absentia.

Inquisition in Germany
The Rhineland and Thuringia in the years 1231-1233 were the field of activity of the notorious inquisitor Konrad of Marburg. Unfortunately, the documentation of his trials has not been preserved, making it impossible to determine the number of his victims. The chronicles only mention "many" heretics that he burned. The only concrete information is about the burning of four people in Erfurt in May 1232.After the murder of Konrad of Marburg, burning at the stake in Germany was virtually unknown for the next 80 years. It was not until the early fourteenth century that stronger measures were taken against heretics, largely at the initiative of bishops. In the years 1311-1315, numerous trials were held against the Waldensians in Austria, resulting in the burning of at least 39 people, according to incomplete records. In 1336, in Angermünde, in the diocese of Brandenburg, another 14 heretics were burned.The number of those convicted by the papal inquisitors was smaller. Walter Kerlinger burned 10 begards in Erfurt and Nordhausen in 1368-1369. In turn, Eylard Schöneveld burned a total of four people in various Baltic cities in 1402-1403.In the last decade of the 14th century, episcopal inquisitors carried out large-scale operations against heretics in eastern Germany, Pomerania, Austria, and Hungary. In Pomerania, of 443 sentenced in the years 1392-1394 by the inquisitor Peter Zwicker, the provincial of the Celestinians, none went to the stake, because they all submitted to the Church. Bloodier were the trials of the Waldensians in Austria in 1397, where more than a hundred Waldensians were burned at the stake. However, it seems that in these trials the death sentences represented only a small percentage of all the sentences, because according to the account of one of the inquisitors involved in these repressions, the number of heretics reconciled with the Church from Thuringia to Hungary amounted to about 2,000.In 1414, the inquisitor Heinrich von Schöneveld arrested 84 flagellants in Sangerhausen, of whom he burned 3 leaders, and imposed penitential sentences on the rest. However, since this sect was associated with the peasant revolts in Thuringia from 1412, after the departure of the inquisitor, the local authorities organized a mass hunt for flagellants and, regardless of their previous verdicts, sent at least 168 to the stake (possibly up to 300) people. Inquisitor Friedrich Müller (d. 1460) sentenced to death 12 of the 13 heretics he had tried in 1446 at Nordhausen. In 1453 the same inquisitor burned 2 heretics in Göttingen.Inquisitor Heinrich Kramer, author of the Malleus Maleficarum, in his own words, sentenced 48 people to the stake in five years (1481-1486). Jacob Hoogstraten, inquisitor of Cologne from 1508 to 1527, sentenced four people to be burned at the stake.

Inquisition in Hungary and the Balkans
Very little is known about the activities of the inquisition in Hungary and the countries under its influence (Bosnia, Croatia), as there are few sources about this activity. Numerous conversions and executions of Bosnian Cathars are known to have taken place around 1239/40, and in 1268 the Dominican inquisitor Andrew reconciled many heretics with the Church in the town of Skradin, but precise figures are unknown. The border areas with Bohemia and Austria were under major inquisitorial action against the Waldensians in the early 15th century. In addition, in the years 1436-1440 in the Kingdom of Hungary, the Franciscan Jacobo de la Marcha acted as an inquisitor... his mission was mixed, preaching and inquisitorial. The correspondence preserved between James, his collaborators, the Hungarian bishops and Pope Eugene IV shows that he reconciled up to 25,000 people with the Church. This correspondence also shows that he punished recalcitrant heretics with death, and in 1437 numerous executions were carried out in the diocese of Sirmium, although the number of those executed is also unknown.

Inquisition in the Czech Republic and Poland
In Bohemia and Poland, the inquisition was established permanently in 1318, although anti-heretical repressions were carried out as early as 1315 in the episcopal inquisition, when more than 50 Waldensians were burned in various Silesian cities. The fragmentary surviving protocols of the investigations carried out by the Prague inquisitor Gallus de Neuhaus in the years 1335 to around 1353 mention 14 heretics burned out of almost 300 interrogated, but it is estimated that the actual number executed could have been even more than 200. , and the entire process was covered to varying degrees by some 4,400 people.In the lands belonging to the Kingdom of Poland little is known of the activities of the Inquisition until the appearance of the Hussite heresy in the 15th century. Polish courts of the inquisition in the fight against this heresy issued at least 8 death sentences for some 200 trials carried out.There are 558 court cases finished with conviction researched in Poland from XV to XVIII centuries.

Early modern European history
With the sharpening of debate and of conflict between the Protestant Reformation and the Catholic Counter-Reformation, Protestant societies came to see/use the Inquisition as a terrifying "Other", while staunch Catholics regarded the Holy Office as a necessary bulwark against the spread of reprehensible heresies.

Witch-trials
While belief in witchcraft, and persecutions directed at or excused by it, were widespread in pre-Christian Europe, and reflected in Germanic law, the influence of the Church in the early medieval era resulted in the revocation of these laws in many places, bringing an end to traditional pagan witch hunts. Throughout the medieval era, mainstream Christian teaching had denied the existence of witches and witchcraft, condemning it as pagan superstition. However, Christian influence on popular beliefs in witches and maleficium (harm committed by magic) failed to entirely eradicate folk belief in witches.
The fierce denunciation and persecution of supposed sorceresses that characterized the cruel witchhunts of a later age were not generally found in the first thirteen hundred years of the Christian era. The medieval Church distinguished between "white" and "black" magic. Local folk practice often mixed chants, incantations, and prayers to the appropriate patron saint to ward off storms, to protect cattle, or ensure a good harvest. Bonfires on Midsummer's Eve were intended to deflect natural catastrophes or the influence of fairies, ghosts, and witches. Plants, often harvested under particular conditions, were deemed effective in healing.Black magic was that which was used for a malevolent purpose. This was generally dealt with through confession, repentance, and charitable work assigned as penance. Early Irish canons treated sorcery as a crime to be visited with excommunication until adequate penance had been performed. In 1258, Pope Alexander IV ruled that inquisitors should limit their involvement to those cases in which there was some clear presumption of heretical belief.
The prosecution of witchcraft generally became more prominent in the late medieval and Renaissance era, perhaps driven partly by the upheavals of the era – the Black Death, the Hundred Years War, and a gradual cooling of the climate that modern scientists call the Little Ice Age (between about the 15th and 19th centuries). Witches were sometimes blamed. Since the years of most intense witch-hunting largely coincide with the age of the Reformation, some historians point to the influence of the Reformation on the European witch-hunt.Dominican priest Heinrich Kramer was assistant to the Archbishop of Salzburg. In 1484 Kramer requested that Pope Innocent VIII clarify his authority to prosecute witchcraft in Germany, where he had been refused assistance by the local ecclesiastical authorities. They maintained that Kramer could not legally function in their areas.The papal bull Summis desiderantes affectibus sought to remedy this jurisdictional dispute by specifically identifying the dioceses of Mainz, Köln, Trier, Salzburg, and Bremen. Some scholars view the bull as "clearly political". The bull failed to ensure that Kramer obtained the support he had hoped for. In fact he was subsequently expelled from the city of Innsbruck by the local bishop, George Golzer, who ordered Kramer to stop making false accusations. Golzer described Kramer as senile in letters written shortly after the incident. This rebuke led Kramer to write a justification of his views on witchcraft in his 1486 book Malleus Maleficarum ("Hammer against witches"). In the book, Kramer stated his view that witchcraft was to blame for bad weather. The book is also noted for its animus against women. Despite Kramer's claim that the book gained acceptance from the clergy at the University of Cologne, it was in fact condemned by the clergy at Cologne for advocating views that violated Catholic doctrine and standard inquisitorial procedure. In 1538 the Spanish Inquisition cautioned its members not to believe everything the Malleus said.

Spanish Inquisition
Portugal and Spain in the late Middle Ages consisted largely of multicultural territories of Muslim and Jewish influence, reconquered from Islamic control, and the new Christian authorities could not assume that all their subjects would suddenly become and remain orthodox Roman Catholics. So the Inquisition in Iberia, in the lands of the Reconquista counties and kingdoms like León, Castile, and Aragon, had a special socio-political basis as well as more fundamental religious motives.In some parts of Spain towards the end of the 14th century, there was a wave of violent anti-Judaism, encouraged by the preaching of Ferrand Martínez, Archdeacon of Écija. In the pogroms of June 1391 in Seville, hundreds of Jews were killed, and the synagogue was completely destroyed. The number of people killed was also high in other cities, such as Córdoba, Valencia, and Barcelona.One of the consequences of these pogroms was the mass conversion of thousands of surviving Jews. Forced baptism was contrary to the law of the Catholic Church, and theoretically anybody who had been forcibly baptized could legally return to Judaism. However, this was very narrowly interpreted. Legal definitions of the time theoretically acknowledged that a forced baptism was not a valid sacrament, but confined this to cases where it was literally administered by physical force. A person who had consented to baptism under threat of death or serious injury was still regarded as a voluntary convert, and accordingly forbidden to revert to Judaism. After the public violence, many of the converted "felt it safer to remain in their new religion". Thus, after 1391, a new social group appeared and were referred to as conversos or New Christians.
King Ferdinand II of Aragon and Queen Isabella I of Castile established the Spanish Inquisition in 1478. In contrast to the previous inquisitions, it operated completely under royal Christian authority, though staffed by clergy and orders, and independently of the Holy See. It operated in Spain and in most Spanish colonies and territories, which included the Canary Islands, the Kingdom of Sicily, and all Spanish possessions in North, Central, and South America. It primarily focused upon forced converts from Islam (Moriscos, Conversos and secret Moors) and from Judaism (Conversos, Crypto-Jews and Marranos)—both groups still resided in Spain after the end of the Islamic control of Spain—who came under suspicion of either continuing to adhere to their old religion or of having fallen back into it.
All Jews who had not converted were expelled from Spain in 1492, and all Muslims ordered to convert in different stages starting in 1501. Those who converted or simply remained after the relevant edict became nominally, and legally Catholics and thus subject to the Inquisition.

Inquisition in the Spanish overseas empire
In the Americas, King Philip II of Spain set up three tribunals (each formally titled Tribunal del Santo Oficio de la Inquisición) in 1569, one in Mexico, Cartagena de Indias (in modern-day Colombia) and Peru. The Mexican office administered Mexico (central and southeastern Mexico), Nueva Galicia (northern and western Mexico), the Audiencias of Guatemala (Guatemala, Chiapas, El Salvador, Honduras, Nicaragua, Costa Rica), and the Spanish East Indies. The Peruvian Inquisition, based in Lima, administered all the Spanish territories in South America and Panama.

Portuguese Inquisition
The Portuguese Inquisition formally started in Portugal in 1536 at the request of King João III. Manuel I had asked Pope Leo X for the installation of the Inquisition in 1515, but only after his death in 1521 did Pope Paul III acquiesce. At its head stood a Grande Inquisidor, or General Inquisitor, named by the Pope but selected by the Crown, and always from within the royal family. The Portuguese Inquisition principally focused upon the Sephardi Jews, whom the state forced to convert to Christianity. Spain had expelled its Sephardi population in 1492; many of these Spanish Jews left Spain for Portugal but eventually were subject to inquisition there as well.
The Portuguese Inquisition held its first auto-da-fé in 1540. The Portuguese inquisitors mostly focused upon the Jewish New Christians (i.e. conversos or marranos). The Portuguese Inquisition expanded its scope of operations from Portugal to its colonial possessions, including Brazil, Cape Verde, and Goa. In the colonies, it continued as a religious court, investigating and trying cases of breaches of the tenets of orthodox Roman Catholicism until 1821. King João III (reigned 1521–57) extended the activity of the courts to cover censorship, divination, witchcraft, and bigamy. Originally oriented for a religious action, the Inquisition exerted an influence over almost every aspect of Portuguese society: political, cultural, and social.
According to Henry Charles Lea, between 1540 and 1794, tribunals in Lisbon, Porto, Coimbra, and Évora resulted in the burning of 1,175 persons, the burning of another 633 in effigy, and the penancing of 29,590. But documentation of 15 out of 689 autos-da-fé has disappeared, so these numbers may slightly understate the activity.

Inquisition in the Portuguese overseas empire
Goa Inquisition
The Goa Inquisition began in 1560 at the order of John III of Portugal. It had originally been requested in a letter in the 1540s by Jesuit priest Francis Xavier, because of the New Christians who had arrived in Goa and then reverted to Judaism. The Goa Inquisition also focused upon Catholic converts from Hinduism or Islam who were thought to have returned to their original ways. In addition, this inquisition prosecuted non-converts who broke prohibitions against the public observance of Hindu or Muslim rites or interfered with Portuguese attempts to convert non-Christians to Catholicism. Aleixo Dias Falcão and Francisco Marques set it up in the palace of the Sabaio Adil Khan.

Brazilian Inquisition
The inquisition was active in colonial Brazil. The religious mystic and formerly enslaved prostitute, Rosa Egipcíaca was arrested, interrogated and imprisoned, both in the colony and in Lisbon. Egipcíaca was the first black woman in Brazil to write a book - this work detailed her visions and was entitled Sagrada Teologia do Amor Divino das Almas Peregrinas.

Roman Inquisition
With the Protestant Reformation, Catholic authorities became much more ready to suspect heresy in any new ideas,
including those of Renaissance humanism, previously strongly supported by many at the top of the Church hierarchy. The extirpation of heretics became a much broader and more complex enterprise, complicated by the politics of territorial Protestant powers, especially in northern Europe. The Catholic Church could no longer exercise direct influence in the politics and justice-systems of lands that officially adopted Protestantism. Thus war (the French Wars of Religion, the Thirty Years' War), massacre (the St. Bartholomew's Day massacre) and the missional and propaganda work (by the Sacra congregatio de propaganda fide) of the Counter-Reformation came to play larger roles in these circumstances, and the Roman law type of a "judicial" approach to heresy represented by the Inquisition became less important overall. In 1542 Pope Paul III established the Congregation of the Holy Office of the Inquisition as a permanent congregation staffed with cardinals and other officials. It had the tasks of maintaining and defending the integrity of the faith and of examining and proscribing errors and false doctrines; it thus became the supervisory body of local Inquisitions. A famous case tried by the Roman Inquisition was that of Galileo Galilei in 1633.
The penances and sentences for those who confessed or were found guilty were pronounced together in a public ceremony at the end of all the processes. This was the sermo generalis or auto-da-fé. Penances (not matters for the civil authorities) might consist of a pilgrimage, a public scourging, a fine, or the wearing of a cross. The wearing of two tongues of red or other brightly colored cloth, sewn onto an outer garment in an "X" pattern, marked those who were under investigation. The penalties in serious cases were confiscation of property by the Inquisition or imprisonment. This led to the possibility of false charges to enable confiscation being made against those over a certain income, particularly rich marranos. Following the French invasion of 1798, the new authorities sent 3,000 chests containing over 100,000 Inquisition documents to France from Rome.

Ending of the Inquisition in the 19th and 20th centuries
By decree of Napoleon's government in 1797, the Inquisition in Venice was abolished in 1806.In Portugal, in the wake of the Liberal Revolution of 1820, the "General Extraordinary and Constituent Courts of the Portuguese Nation" abolished the Portuguese inquisition in 1821.
The wars of independence of the former Spanish colonies in the Americas concluded with the abolition of the Inquisition in every quarter of Hispanic America between 1813 and 1825.
The last execution of the Inquisition was in Spain in 1826. This was the execution by garroting of the Catalan school teacher Gaietà Ripoll for purportedly teaching Deism in his school. In Spain the practices of the Inquisition were finally outlawed in 1834.In Italy, the restoration of the Pope as the ruler of the Papal States in 1814 brought back the Inquisition to the Papal States. It remained active there until the late-19th century, notably in the well-publicised Mortara affair (1858–1870). In 1908 the name of the Congregation became "The Sacred Congregation of the Holy Office", which in 1965 further changed to "Congregation for the Doctrine of the Faith", as retained to the present day.

Methods of torture used
Defendants were commonly interrogated under torture and finally punished if found guilty, with their property being requisitioned in the process to defray legal costs and prison costs. They could also repent of their accusation and receive reconciliation with the Church. The execution of the tortures was attended by the inquisitor, the doctor, the secretary and the executioner, applying them (except in the case of women) on the completely naked prisoner. In the year 1252, the Bull Ad Extirpanda admits torture, but always with a doctor involved to avoid endangering life, and limited its use to 3 methods (not one of which was bloody):

Strappado: the victim was lifted to the ceiling with his arms tied behind his back.
Rack: the prisoner was tied to a frame and the executioner pressed until the meat was pierced.
Water cure: the prisoner was tied, a cloth was inserted through his mouth down to his throat and jugs of water of approximately one liter were poured.According to the Catholic Church, the method of torture (which was socially accepted in the context of the time) was adopted only in exceptional cases. The inquisitorial procedure was meticulously regulated in interrogation practices.
Torture cannot endanger a person's life.
Torture cannot cause you to lose a limb.
Torture could only be applied once, and only if the defendant appeared to be lying.
If the inquisitor already had overwhelming evidence of the accused's guilt, it was forbidden to take them to the torture room.Not all civilly accepted methods of torture were endorsed by the Catholic Church and for a defendant to be sent to torture, he must be prosecuted for a crime considered serious, and the court must also have well-founded suspicions of his guilt. None of these were originated by the Holy Office, rather they were used by civil authorities. 
Despite the use of torture, the inquisitorial procedure represents a breakthrough in the history of legislation. On the one hand, it definitely ruled out the use of the ordeal, a Germanic tradition long condemned by the hierarchy, without taking disciplinary measures against it, as a means of obtaining evidence, replacing it with the principle of testimonial evidence, which is still in force in current laws. On the other hand, the principle of the State as prosecutor or accusing party is restored. Until that time, it was the victim who had to prove the guilt of her aggressor, even in the most serious criminal proceedings, this was often very difficult when the victim was weak and the criminal powerful. But in the Inquisition, the victim is no more than a simple witness, as happens in countries where an inquisitive system is applied. It was the ecclesiastical authority who now had the burden of proof.[citation needed]. The summary of the 'Directorium Inquisitorum', by Nicolás Aymerich, made by Marchena, notes a comment by the Aragonese inquisitor: 'Quaestiones sunt fallaces et inefficaces' -The interrogations are misleading and useless-

Fake instruments of torture
Despite what is popularly believed, the cases in which torture methods were used during the inquisitorial processes were rare, since it was considered to be ineffective in obtaining evidence, in addition to the fact that, in the vast majority of cases, said instruments mainly had the purpose of achieving the intimidation of the accused and were not used, their use being more the exception than the norm.Which in the words of historian Helen Mary Carrel: "the common view of the medieval justice system as cruel and based on torture and execution is often unfair and inaccurate." As the historian Nigel Townson would say: "The sinister torture chambers equipped with cogwheels, bone crushing contraptions, shackles and other terrifying mechanisms only existed in the imagination of their detractors".
Some instruments of torture awarded to the Inquisition, actually originated in the Protestant Churches and/or used by civil authorities, such as those presented in the Constitutio Criminalis Theresiana (of the Habsburg Monarchy) or the Ordonnance de Blois (of the Parliament of Paris). Being modern, not medieval, inventions that were not related to the Inquisition.
Many were designed by late 18th and early 19th century pranksters, entertainers and con artists who wanted to profit from people's morbid interest in the Dark Age myth by charging them to witness such instruments in Victorian-era circuses, for example, the horned "Viking" helmet, popularized in 19th-century dramas and operas as a "Dark Age" display, despite never being worn.
However several torture instruments are accurately described in Fox's Book of the Martyrs including but not limited to the dry pan etc
Here's a list of the instruments that the Inquisition never used, but that are erroneously registered in various inquisition museums:
The troublemaker's flute: Created in the 17th century. Its first mention comes from the years 1680-90 of the Republic of Venice used against deserters from the war between the Ottoman Empire and the Republic of Venice.
Head crusher: Created in the 14th century. Its first mention comes from 1340 in Germany. It was not used by the Inquisition but by the German courts against the enemies of some electors.
Judas's cradle: Created in the fifteenth century. Its first mention comes from 1450-80 in France. Used by the French Parliament and not by the Inquisition, it was abolished in 1430.
The Spanish donkey: Created in the 16th century. The name connects the instrument to the Spanish Inquisition, although it was only used in certain regions, which were not primarily Spain nor as part of the Inquisition, but by Central European civil authorities (most notably Reformed Germany and the Bohemian Crown), New France, the Netherlands Antilles, the British Empire, and the United States. It is unclear exactly who invented the torture device and it is likely that it was awarded to the Spanish for anti-Hispanic propaganda reasons.
The Spanish tickle: Created in 2005 as a false rumor on Wikipedia.
The Thumbscrew: Created in the 16th century. It was used for the persecution of Catholics by William Cecil in England during the reign of Elizabeth I. It was not used by the Inquisition, but by the English courts against dissidents to the Protestant Reformation, later also for the torture of slaves.
The saw. Created in the fifteenth century. Its first mention comes from 1450-70. Used by the Hungarian court against Muslims in the context of the war between the Ottoman Empire, the Byzantine Empire and the Kingdom of Hungary.
Pear of anguish: Created in the fifteenth century. Its first mention comes from 1450. Used by the French parliament and not by the Inquisition, it was abolished in 1430. The historian Chris Bishop came to postulate that it could have actually been a sock stretcher, since it has been proven that it was too weak to open into a body orifice.
The Spanish Boot: Created in the 14th century. Its first mentions come from Scotland with the buskin. Used by the authorities in England to persecute Catholics in Ireland. Later the civil authorities of France and Venice would use it, but not by the Spanish Inquisition.
The Cloak of Infamy. Created in the 17th century. Its first mention comes from Johann Philipp Siebenkees in 1790. Used by the Nuremberg parliament (Protestant) against thieves and prostitutes.
The Iron Maiden. Created in the 19th century. Invented on the orders of the Protestant and Prussian elite of the German Second Reich as part of the Kulturkampf's anti-Catholic propaganda to make the medieval era appear more barbaric, based on the 17th century Cloak of Infamy for Our Lady of Nuremberg (Lutheran).
The Breast ripper. Created at the end of the 16th century. The first reference dates back to Bavaria (Germany) in 1599 and presumably it would have been used in France and Holy Roman Empire by civil authorities and not by the Inquisition. However, there are no reliable first-hand historical sources on the use of the devices, so, like the Iron Maiden, there is a possibility that the devices shown in the images are fakes of a later manufacture (such as from the 17th century) or assembled from small fragments that may have been parts of another device. Most likely, it was often mentioned to frighten and force the accused to confess, rather than such dubiously existent torture being inflicted on them.
The Stocks. Created in the Middle Ages and used by the civil authorities of London, not the Inquisition, in order to publicly shame criminals, but not physically harm them or take life.
The bronze bull. Created in the Ancient Age and never used in medieval Europe, much less in the Inquisition. In fact, there is a chance that it never existed at all and was just a popular legend of Greco-Latin culture.
The mask. Created in the 16th century. It was never legalized and was only used unofficially by some civilians in Scotland and England, not by the Inquisition.
The dungeon of rats. Created in the 16th century, its main reference is from John Lothrop Motley about some anecdotes of torture against the "papists" during the war of independence in the Netherlands. It is also said that Catholics who opposed the schism of the Anglican Church promoted by Elizabeth I of England were tortured in the Tower of London. Used by some Protestant governments and not by the Inquisition.
Heretics' Fork, Boots, Cat's Paw, and Iron Cage. Created in the 15th-16th century. Used by the French Parliament and not by the Inquisition.

Statistics
Beginning in the 19th century, historians have gradually compiled statistics drawn from the surviving court records, from which estimates have been calculated by adjusting the recorded number of convictions by the average rate of document loss for each time period. Gustav Henningsen and Jaime Contreras studied the records of the Spanish Inquisition, which list 44,674 cases of which 826 resulted in executions in person and 778 in effigy (i.e. a straw dummy was burned in place of the person). William Monter estimated there were 1000 executions between 1530–1630 and 250 between 1630 and 1730. Jean-Pierre Dedieu studied the records of Toledo's tribunal, which put 12,000 people on trial. For the period prior to 1530, Henry Kamen estimated there were about 2,000 executions in all of Spain's tribunals. Italian Renaissance history professor and Inquisition expert Carlo Ginzburg had his doubts about using statistics to reach a judgment about the period. "In many cases, we don't have the evidence, the evidence has been lost," said Ginzburg.

Appearance in popular media
In the Monty Python comedy team's Spanish Inquisition sketches, an inept Inquisitor group repeatedly bursts into scenes after someone utters the words "I didn't expect a kind of Spanish Inquisition", screaming "Nobody expects the Spanish Inquisition!" The Inquisition then uses ineffectual forms of torture, including a dish-drying rack, soft cushions and a comfy chair.
The 1982 novel Baltasar and Blimunda by José Saramago, portrays how the Portuguese Inquisition impacts the fortunes of the title characters as well as several others from history, including the priest and aviation pioneer Bartolomeu de Gusmão.

In the novel La Catedral del Mar by Ildefonso Falcones, and Netflix series Cathedral of the Sea based on the novel, there are scenes of inquisition investigations in small towns and a great scene in Barcelona.
Miloš Forman's "Goya's Ghosts", released June 9, 2007 in the US, brings to light the stories behind some of Spanish painter Francisco Goya's paintings during the Spanish Inquisition, particularly one of a priest condemning and imprisoning a beautiful woman for his own benefit. Her family retaliates, but cannot save her.

They are known for maintaining the enforced galaxy-wide religion of the Imperial Cult which revolves around worshipping the super meta human Emperor of Mankind and his super soldier armies. This is done knowing the Emperor himself during his active rule stated he wanted humanity to be atheist.
The music video for Pet Shop Boys' song It's a Sin (1987) features the inquisition trying the lead singer while he is holding two big candles.
