Marranos or Secret Jews were Sephardic Jews (Jews resident in the Iberian peninsula) who were forced to adopt Christianity or leave Spain, but became false Roman Catholic converts to assimilate to society and secretly practiced Judaism. Many Marranos maintained their ancestral traditions as crypto-Jews by publicly professing Roman Catholicism but secretly adhering to Judaism. The term in (Spanish and Portuguese meant "pigs", and was derived from a derogatory word in Arabic محرّم muharram meaning "ritually forbidden". It stemmed from the ritual prohibition against eating pork among both Jews and Muslims). In both Portuguese and Spanish, the term marrano acquired the meaning of "swine" or "filthy" (but in contemporary Spanish it has no association with Jews).
These conversos (converts), as they were also called, numbered over 100,000 in the Iberian Peninsula. They were also known by the name of Cristianos nuevos and Cristãos novos (New Christians) in Spain and Portugal, respectively. They were called xuetes in Catalan, derived from xua, a Catalan word referring to a pork recipe consumed publicly by xuetes in the Balearic Isles to display the sincerity of their Catholicism. Hebrew-speakers called such converts anusim (constrained). (Anusim is a general word for forced converts from Judaism and is not specific to this period.)
A number of Spanish poets belong to this category, such as Pero Ferrus, Juan de Valladolid, Rodrigo Cota, and Juan de España of Toledo, called also "El Viejo" (the old one), who was considered a sound Talmudist, and who, like the monk Diego de Valencia, himself a baptized Jew, introduced in his pasquinades Hebrew and Talmudic words to mock the Jews. There were also many who, for the sake of displaying their new zeal, persecuted their former co-religionists, writing books against them, and denouncing to the authorities those who wished to return to the faith of their forefathers, as happened frequently at Valencia, Barcelona, and many other cities (Isaac b. Sheshet, Responsa, No. 11).
To the Conversos who lived in secret conformity with Jewish law, the Rabbis applied the Talmudic passage: "Although he has sinned, he must still be considered a Jew". According to rabbinic law, anusim, who took the first opportunity of going to a foreign country and openly professing Judaism, were allowed to act as witnesses in religious matters.
In the early 20th century historian Samuel Schwartz wrote about a few Crypto-Jewish communities in northeastern Portugal (namely in Belmonte, Bragança, Miranda, Chaves, among others). Members had managed to survive more than four centuries without being fully assimilated into the Old Christian population. The last remaining community in Belmonte officially returned to Judaism in the 1970s, and opened a synagogue in 1996. In 2003, the Belmonte Project was founded under the auspices of the American Sephardi Federation, to raise funds to acquire Judaic educational material and services for the community, who then numbered 160-180.
The church considered the Conversos neither Christians nor Jews, but atheists and heretics and the cause of a months-long plague that affected the city in 1506. On April 17, 1506, several Conversos were discovered who had in their possession "some lambs and poultry prepared according to Jewish custom; also unleavened bread and bitter herbs according to the regulations for the Passover, which festival they celebrated far into the night." Several of them were seized, but were released after a few days.
The populace, which had expected to see them punished, swore vengeance. On the same day on which the Conversos were liberated, the Dominicans displayed in a side-chapel of their church, where several New Christians were present, a crucifix and a reliquary in glass from which a peculiar light issued. A New Christian, who tried to explain the miracle as due to natural causes, was dragged from the church and killed by an infuriated woman. A Dominican roused the populace still more. Friar João Mocho and the Aragonese friar Bernardo, crucifix in hand, were said to go through the streets of the city, crying "Heresy!" and calling upon the people to destroy the Conversos. Attracted by the outcry, sailors from Holland, Zealand and others from ships in the port of Lisbon, joined the Dominicans and formed a mob with local men to pursue the Conversos of Lisbon.
The mob killed all New Christians found in the streets. More than 500 Conversos were slain and burned on the first day; and the scenes of murder were even more atrocious on the day following. The mob dragged innocent victims dragged from their houses and threw them on the pyre. Even Old Christians who in any way resembled Conversos were killed. Among the last victims, and the most hated of all, was the tax-farmer João Rodrigo Mascarenhas, one of the wealthiest and most distinguished Conversos of Lisbon; his house was entirely demolished. In this manner at least 2,000 Conversos perished (as many as 4,000 by some accounts) within forty-eight hours. By the third day there were no more Conversos in town because some Portuguese helped them escape.
King Manuel severely punished the inhabitants who took part in the killings. The ringleaders were either hanged or quartered, and the Dominicans who had occasioned the riot were garroted and burned. Local people convicted of murder or pillage suffered corporal punishment, and their property was confiscated. The king granted religious freedom to all Conversos for twenty years. Lisbon lost Foral privileges. The foreigners who took part in the massacre left in their ships with their loot and escaped punishment.
In 2006, the Jewish community of Portugal held a ceremony in Lisbon to commemorate this event.
The New Christians of Portugal, who were distinguished for their knowledge, their commerce, and their banking enterprises, and resented for their power by competing and lower class Christians, began to hope for the future when the foreign Jew, David Re'ubeni arrived. Not only was this Jew invited by King John to visit Portugal; but, as appears from a letter (Oct. 10, 1528) of D. Martin de Salinas to the infante D. Fernando, brother of the emperor Charles I of Spain, he also received permission "to preach the law of Moses" ("Boletin Acad. Hist." xlix. 204). The Conversos regarded Re'ubeni as their savior and Messiah.
The New Christians of Spain also heard the news; and some of them left home to seek Re'ubeni out. The rejoicing lasted for some time; the emperor Charles even addressed several letters on the matter to his royal brother-in-law. In 1528, while Re'ubeni was still in Portugal, some Spanish Conversos fled to Campo Mayor and forcibly freed from the Inquisition a woman imprisoned at Badajoz. The rumor spread that the Conversos of the entire kingdom had united to make common cause. This increased the resentment and fear of the populace. They attacked New Christians in Gouvea, Alentejo, Olivença, Santarém, and other places, while in the Azores and the island of Madeira they massacred the former Jews. Because of these excesses, the king began to believe that a Portuguese Inquisition might help control such outbreaks.
The Portuguese Conversos waged a long and bitter war against the introduction of the tribunal, and spent immense sums to win over the Curia and most influential cardinals. The sacrifices made by both the Spanish and the Portuguese New Christians were substantial. Alfonso Gutierrez, Garcia Alvarez "el Rico" (the wealthy), and the Zapatas, conversos from Toledo, offered 80,000 gold crowns to Emperor Charles V if he would mitigate the harshness of the Inquisition (Revue des Etudes Juives, xxxvii. 270 et seq.). All these sacrifices, however, including those made by the Mendes of Lisbon and Flanders, were powerless to prevent or retard the introduction of the Holy Office into Portugal. The Conversos suffered immensely at the hands of the Inquisition and in mob violence. At Trancoso and Lamego, where many wealthy Conversos were living, at Miranda, Viseu, Guarda, Braga, and elsewhere they were robbed and killed. At Covilhã the people planned to massacre all the New Christians on one day. In 1562 the prelates petitioned the Cortes to require Conversos to wear special badges, and to order Jews to live in ghettos (judiarias) in cities and villages as before.
The large numbers of the Conversos, as well as their wealth and influence, aroused the envy and hatred of the populace, whom the clergy incited against them as unbelieving Christians and hypocrites. The New Christians were hated much more than the Jews, and were persecuted as bitterly as their former coreligionists had been. According to historian Cecil Roth, political intrigues in Spain promoted anti-Jewish policies, which culminated in 1391, when Regent Queen Leonora of Castile gave the Archdeacon of Ecija, Ferrand Martinez, considerable power in her realm. Martinez gave speeches that led to violence against the Jews, and this influence culminated in the sack of the Jewish quarter of Seville on June 4, 1391. Throughout Spain during this year, the cities of Ecija, Carmona, Córdoba, Toledo, Barcelona and many others saw their Jewish quarters destroyed and massacred. It is estimated that 200,000 Jews saved their lives by converting to Christianity in the wake of these persecutions. Another riot against them broke out at Toledo in 1449, and was accompanied with murder and pillage. Instigated by two canons, Juan Alfonso and Pedro Lopez Galvez, the mob plundered and burned the houses of Alonso Cota, a wealthy Converso and tax-farmer, and under the leadership of a workman they likewise attacked the residences of the wealthy New Christians in the quarter of la Magdelena. The Conversos, under Juan de la Cibdad, opposed the mob, but were repulsed and, with their leader, were hanged by the feet. As an immediate consequence of this riot, the Conversos Lope and Juan Fernandez Cota, the brothers Juan, Pedro, and Diego Nuñez, Juan Lopez de Arroyo, Diego and Pedro Gonzalez, Juan Gonzalez de Illescas, and many others were deposed from office, in obedience to a new statute.
Another attack was made upon the New Christians of Toledo in July 1467. The chief magistrate (alcalde mayor) of the city was Alvar Gomez de Cibdad Real, who had been private secretary to King Henry IV of Castile, and who, if not himself a "converso," as is probable, was at least the protector of the New Christians. He, together with the prominent Conversos Fernando and Alvaro de la Torre, wished to take revenge for an insult inflicted by the counts de Fuensalida, the leaders of the Christians, and to gain control of the city. A fierce conflict was the result. The houses of the New Christians near the cathedral were fired by their opponents, and the conflagration spread so rapidly that 1,600 houses were consumed, including the beautiful palace of Diego Gomez. Many Christians and still more Conversos perished in the flames or were slain; and the brothers De la Torre were captured and hanged.
In 1473 attacks on the Conversos arose in numerous cities. At Montoro, Bujalance, Adamuz, La Rambla, Santaella, and elsewhere, mobs attacked and killed them and plundered their houses. At Jaén a constable who tried to protect the conversos was attacked and killed in church by the ringleaders. Mobs attacked conversos in Andujar, Úbeda, Baeza, and Almodovar del Campo also. In Valladolid groups looted the belongings of the New Christians, but there was a massacre at Segovia (May 16, 1474). D. Juan Pacheco, a Converso, led the attacks. Without the intervention of the alcalde Andreas de Cabrerafamily, all New Christians may have died. At Carmona every Converso was killed.
The historian Henry Kamen's recent Inquisition and Society In Spain in the sixteenth and seventeenth centuries questions whether there were such strong links between Conversos and Jewish communities. Whilst historians such as Yitzhak Baer state, "the conversos and Jews were one people, Kamen claims that "Yet if the conversos were hated by the Christians, the Jews liked them no better. He documented that "Jews testified falsely against them [the conversos] when the Inquisition was finally founded. This issue is being debated by historians.
Spanish and Portuguese Conversos settled also at Florence; and New Christians contributed to make Leghorn a leading seaport. They received privileges at Venice, where they were protected from the persecutions of the Inquisition. At Milan they materially advanced the interests of the city by their industry and commerce. At Bologna, Pisa, Naples, Reggio, and many other Italian cities they freely exercised their religion, and were soon so numerous that Fernando de Goes Loureiro, an abbot from Oporto, filled an entire book with the names of the Conversos who had drawn large sums from Portugal and had openly avowed Judaism in Italy.
In Piedmont Duke Emmanuel Philibert of Savoy welcomed Conversos from Coimbra, and granted them commercial and industrial privileges, as well as the free exercise of their religion. Rome was full of Conversos. Pope Paul III received them at Ancona for commercial reasons, and granted complete liberty "to all persons from Portugal and Algarve, even if belonging to the class of New Christians." Three thousand Portuguese Jews and Conversos were living at Ancona by 1553.
Two years later the fanatical Pope Paul IV issued orders to have all the Conversos thrown into the prisons of the Inquisition which he had instituted. Sixty of them, who acknowledged the Catholic faith as penitents, were transported to the island of Malta; twenty-four, who adhered to Judaism, were publicly burned (May, 1556). Those who escaped the Inquisition were received at Pesaro by Duke Guido Ubaldo of Urbino. Guido had hoped to have the Jews and Conversos of Turkey select Pesaro as a commercial center; when that did not happen, he expelled the New Christians from Pesaro and other districts in 1558 (ib. xvi. 61 et seq.).
Many Conversos also went to Dubrovnik, formerly a considerable seaport. In May, 1544, a ship landed there filled with Portuguese refugees.
Large numbers of Conversos, however, remained in Spain and Portugal, despite the extensive emigration and the fate of countless victims of the Inquisition. The New Christians of Portugal breathed more freely when Philip III of Spain came to the throne and by the law of April 4, 1601, granted them the privilege of unrestricted sale of their real estate as well as free departure from the country for themselves, their families, and their property. Many, availing themselves of this permission, followed their coreligionists to Africa and Turkey. After a few years, however, the privilege was revoked, and the Inquisition resumed its activity. But the Portuguese who were not affected by radicalism perceived that no forcible measures could induce the Conversos to give up the religion of their fathers.
Individual New Christians, as Antonio Fernandez Carvajal and several from Spain, Hamburg, and Amsterdam, went to London, whence their families spread to Brazil, where Conversos had settled at an early date, and to other colonies of the Americas. The migrations to Constantinople and Salonica, where Jewish refugees had settled after the expulsion from Spain, as well as to Serbia, Romania and Bulgaria, and to Vienna and Timişoara, continued to the middle of the 18th century.
