|Jews and Judaism|
Crypto-Judaism is the secret adherence to Judaism while publicly professing to be of another faith; practitioners are referred to as "crypto-Jews" (origin from Greek kryptos - κρυπτός, 'hidden'). The term crypto-Jew is also used to describe descendants who maintain some Jewish traditions of their ancestors while publicly adhering to other faiths. The term is especially applied historically to European Jews who—outwardly or forcedly—professed Catholicism, also known as Anusim or Marrano. The phenomenon is especially associated with early modern Spain, following the June 6th 1391 Anti-Jewish pogroms and the expulsion of the Jews in 1492.

Officially, Jews who converted in Spain in the 14th and 15th centuries were known as Cristianos Nuevos (New Christians), but were commonly called conversos. Spain and Portugal passed legislation restricting their rights in the mother countries and colonies. Despite the dangers of the Inquisition, many conversos continued to secretly and discreetly practice Jewish rituals.
In the Balearic Islands, numerous conversos, also called Chuetas, publicly professed Roman Catholicism but privately adhered to Judaism after the Alhambra decree of 1492 and during the Spanish Inquisition. They are among the most widely known crypto-Jews.
In Greece "Romaniote Jews" have been present for a little more than two thousand years. Greek Jews played an important role in the early development of Christianity, and became a source of education and commerce for the Byzantine Empire and throughout the period of Ottoman Greece, until suffering devastation in the Holocaust after Greece was conquered and occupied by the Axis powers in spite of efforts by Greeks to protect them. In the aftermath of the Holocaust, a large percentage of the surviving community emigrated to Israel or the United States. Greek Jews today largely "live side by side in harmony" with Christian Greeks, according to Giorgo Romaio, president of the Greek Committee for the Jewish Museum of Greece, while nevertheless continuing to work with other Greeks, and Jews worldwide, to combat any rise of anti-Semitism in Greece.
Crypto-Judaism dates back to earlier periods when Jews were forced or pressured to convert by the rulers of places they lived in.
Some of the Jewish followers of Sabbatai Zevi (Sabbateans) formally converted to Islam, and later followers of Jacob Frank ("Frankists") formally converted to Christianity, but maintained aspects of their versions of Messianic Judaism.
Crypto-Jews persisted in Russia and Eastern European countries influenced by the Soviet Union after the rise of Communism with the Russian Revolution of 1917. Rather than being forced to convert, all religion was regarded as undesirable, although some faiths were allowed to continue under strict supervision by the regime. Since the end of Communism, many people in former Soviet states, including descendants of Jews, have publicly taken up the faith of their families again.
The "Belmonte Jews" of Portugal, dating from the 12th century, maintained strong secret traditions for centuries. A whole community survived in secrecy by maintaining a tradition of intermarriage and hiding all external signs of their faith. They and their practices were discovered only in the 20th century. Their rich Sephardic tradition of Crypto-Judaism is unique. Only recently did they contact other Jews. Some now profess Orthodox Judaism, although many still retain their centuries-old traditions.
Before the Spanish Inquisition
According to the Jewish Virtual Library, several incidents of forced conversions happened prior to 1492 and outside of Iberia. One of the earliest conversions happened a century after the Fall of Rome and was in Clermont-Ferrand. After a member of the Jewish community in Clermont-Ferrand became a Jewish Christian and was persecuted by other members of the community for doing so, the cavalcade in which he was marching persecuted his persecutors in turn:
The participants in the procession then made an attack "which destroyed [the synagogue] completely, razing it to the grounds." Subsequently, Bishop *Avitus directed a letter to the Jews in which he disclaimed the use of compulsion to make them adopt Christianity, but announced at the end of the missive: "Therefore if ye be ready to believe as I do, be one flock with us, and I shall be your pastor; but if ye be not ready, depart from this place." The community hesitated for three days before making a decision. Finally the majority, some 500, accepted Christianity. The Christians in Clermont greeted the event with rejoicing: "Candles were lit, the lamps shone, the whole city radiated with the light of the snow-white flock" (i.e., the forced converts). The Jews who preferred exile left for *Marseilles (Gregory of Tours, Histories, 5:11) The poet Venantius Fortunatus composed a poem to commemorate the occasion. In 582 the Frankish king Chilperic compelled numerous Jews to adopt Christianity. Again the anusim were not wholehearted in their conversion, for "some of them, cleansed in body but not in heart, denied God, and returned to their ancient perfidy, so that they were seen keeping the Sabbath, as well as Sunday" (ibid., 6:17).
Persistent attempts to enforce conversion were made in the seventh century by the Visigoths in Spain after they had adopted the Roman Catholic faith. Comparatively mild legal measures were followed by the harsh edict issued by King Sisibut in 616, ordering the compulsory baptism of all Jews. After conversion, however, the anusim evidently maintained their Jewish cohesion and religious life. It was undoubtedly this problem that continued to occupy Spanish sovereigns at the successive Councils of Toledo representing both the ecclesiastical and secular authorities...Thus, steps were taken to secure that the children of converts had a Christian religious education as well as to prevent the older generation from continuing to observe the Jewish rites or from failing to observe the Catholic ones. A system of strict supervision by the clergy over the way of life and movements of the anusim was imposed...
The final conversions in Iberia (which had Al-Andalus) prior to 1492 (with the 1492 ones being effected by ones that began in 1391) happened in the 1100s and were Muslim-forced conversions. The final ones outside of Iberia before 1492 happened in Italy in the 1200s and spread as far as Apulia, where the Anusim Italqim assimilated to the point of not being recognized as Jewish (as was later observed): "'[T]heir forefathers were Jews who adopted Christianity 150 years ago, rather from compulsion than of their own free will.'"
The Xueta are a minority on the Balearic island of Majorca (Mallorca) who are descended almost entirely from crypto-Jews, forced to convert in 1391. The term "xueta" literally translates to "pig" in Catalan, similar to the old Spanish (Castilian) term and marrano, both of the same meaning.
Today, they comprise a population of 20,000–25,000 on an island of 750,000; they have professed Roman Catholicism for centuries but have only recently seen a lessening in tensions with ethnic Majorcans. According to some Orthodox rabbis, the majority of Xuetes are probably Jewish under Jewish law (by descent from Jewish mothers) due to the low rate of intermarriage with outside groups. Only recently have intermarriages between the two groups been more prevalent or noticeable.
During World War II, Nazi Germany was known to have pressured Majorcan religious authorities into surrendering the Xuetes, targeted because of their Jewish ancestry. Reportedly the religious authorities refused the Nazi request.
Several Xuetes are reported to have "reconverted" to Judaism. Some have become rabbis.
There are, or have been, several communities of Crypto-Jews in Muslim lands. The ancestors of the Daggatuns in Morocco probably kept up their Jewish practices a long time after their nominal adoption of Islam. In Iran, a large community of Crypto-Jews lived in Mashhad, near Khorassan, where they were known as "Jedid al-Islam", who were mass-converted to Islam around 1839 after the Allahdad events. Most of this community left for Israel in 1946, but some have converted into Muslims and live in Iran today. In the central Iranian village of Sebe, local Muslims practice many Jewish customs, such as women lighting a candle on Friday night (the eve of the Jewish Sabbath). Before sundown on Friday, they prepare a small fire which they leave on throughout Saturday, so as not to ignite the fire on Sabbath.
There are three distinct historical components to colonial roots of crypto-Judaism, largely restricted to Spanish-held territories in Mexico, each with distinct geographical and temporal aspects: early colonial roots, the frontier province of Nuevo León, and the later northern frontier provinces. The crypto-Jewish traditions have complex histories and are typically embedded in an amalgam of syncretic Roman Catholic and Judaic traditions. In many ways resurgent Judaic practices mirrored indigenous peoples' maintaining their traditions practiced loosely under Roman Catholic veil. In addition, Catholicism was syncretic, absorbing other traditions and creating a new creole religion.
Early colonial period—16th century
However, Portugal in 1497 issued a similar decree that effectively converted all remaining Jewish children, making them wards of the state unless the parents also converted. Therefore, many of the early crypto-Jewish migrants to Mexico in the early colonial days were technically first to second generation Portuguese with Spanish roots before that. The number of such Portuguese migrants was significant enough that the label of "Portuguese" became synonymous with "Jewish" throughout the Spanish colonies. Immigration to Mexico offered lucrative trade possibilities in a well-populated colony with nascent Spanish culture counterbalanced by a large non-Christian population. Migrants thought the culture would be more tolerant since the lands were overwhelmingly populated by non-Christian indigenous peoples.
Colonial officials believed that many crypto-Jews were going to Mexico during the 16th century and complained in written documents to Spain that Spanish society in Mexico would become significantly Jewish. Officials found and condemned clandestine synagogues in Mexico City. At this point, colonial administrators instituted the Law of the Pure Blood, which prohibited migration to Mexico for New Christians (Cristiano Nuevo), i.e. anyone who could not prove to be Old Christians for at least the last three generations. During this time, the administration initiated the Mexican Inquisition to ensure the Catholic orthodoxy of all migrants into Mexico. The Mexico Inquisition was also deployed in the traditional manner to ensure orthodoxy of converted indigenous peoples. The first victims of burnings or autos de fé of the Mexican Inquisition were indigenous converts convicted of heresy or crypto-Jews convicted of relapsing into their ancestral faith.
Except for the province of Nuevo Leon, initiation of the Blood Purity Laws reduced the migration of conversos.
Nuevo León—1590s to early 17th century
The history of the colonization of New Spain can be described as a northward expansion over increasingly hostile geography well-populated by angered tribes and loose confederations of indigenous peoples. Spain financed the expansion by exploiting mineral wealth, enslaving or forcing indigenous peoples to labor in mines, and establishing encomiendas for raising livestock, thereby displacing the local people. One troublesome region was a large expanse covering the North-Eastern quadrant of New Spain (Nueva España). Chichimec, Apache and other tribes were resistant to becoming Christian and laborers or slaves on Spanish ranches and in mines. They were perceived to render the frontier (frontera) a lawless region.
Luis Carvajal y de la Cueva was a Portuguese New Christian royal accountant who received a royal charter to settle Nuevo León, a large expanse of land in the hostile frontier. Significantly, in the charter Carvajal y de la Cueva received an exemption from the usual requirement that he prove that all new settlers were "old Christians" rather than recently converted Jews or Muslims. This exemption allowed people, especially Crypto-Jews, to come to Nuevo León who were legally barred from entering New Spain elsewhere. Many of the 100 soldiers and 60 laborers Carabajal was authorized to bring to New Spain were Crypto-Jews.
With Carvajal as governor, Monterrey was established as the center, currently in the state of Nuevo León. Within a few years, some people reported to Mexico City that Jewish rites were being performed in the Northern Province and efforts to convert heathen indigenous peoples were lax. The principal economic activity of Carvajal and his associates seems to have been capturing Indians and selling them into slavery. Carvajal's Lieutenant Governor, Gaspar Castaño de Sosa, led a large expedition to New Mexico in 1591 in an effort to establish a colony. Castaño was arrested for this unauthorized expedition and sentenced to exile in the Philippines. The sentence was later reversed but he had already been killed in a slave revolt.
The governor, his immediate family members, and others of his entourage were called to appear before the Inquisition in Mexico City. They were arrested and jailed. The governor subsequently died in jail, while his family members were rehabilitated. One of these was Anna Carvajal, a niece of the Governor. She and others were later again taken captive and sentenced to burning at the stake for relapsing.
The governor's nephews changed their name to Lumbroso. One of these was Joseph Lumbroso, also known as Luis de Carvajal el Mozo, who is said to have circumcised himself in the desert to conform to Jewish law. His memoirs, letters and inquisition record survive. Two other nephews also changed their names to Lumbroso and migrated to Italy, where they became famous rabbis.
When Governor Carvajal was in office, the city of Monterrey became a destination for other crypto-Jews feeling the pressure of the Mexican Inquisition in the south of the territory. Thus, the story of Nuevo León and the founding of Monterrey are significant as it attracted crypto-Jewish migrants from all parts of New Spain. They created one of the earliest Jewish-related communities in earlier Mexico. (The Jewish communities in modern Mexico which practice their Judaism openly were not established until the considerable immigration from eastern Europe, Turkey and Syria in the late 19th century and 20th century.)
Former New Spain territories in the modern-day southwestern U.S., 17th–18th centuries
Due to the activities of the New Spain Inquisition in Nuevo León, many crypto-Jewish descendants migrated to other frontier colonies further west to the trade routes passing through the towns of Sierra Madres Occidental and Chihuahua, Hermosillo and Cananea (Canaan) and further north on the trade route to Paso del Norte (Juarez/El Paso) and Santa Fe (both cities in the then colonial Province of New Mexico), and somewhat less in Alta California.
In the former Spanish-held northern New Spain (modern-day Southwestern United States), some Hispanic Roman Catholics have stated a belief, not supported by proof, that they are descended from crypto-Jews and have started practicing Judaism. They often cite as evidence memories of older relatives practicing Jewish traditions. The crypto-Jews of New Mexico have been documented by several research scholars including Stanley M. Hordes, Janet Liebman Jacobs, Schulamith Halevy, and Seth D. Kunin. Only one researcher, folklorist Judith Neulander, has been skeptical of the authenticity of the Jewish ancestry of Hispanos of the Southwest, she argues that these remembered traditions could be those of Ashkenazi, not Sephardi, Jews and may possibly be constructed memories due to suggestion by proponents. She also argues that the Jewish traditions practiced by older relatives were introduced by groups of Evangelical Protestant Christians who purposely acquired and employed Jewish traditions as part of their religious practices. Neulander's theory has been directly addressed in Kunin's book "Juggling Identities: Identity and Authenticity Among the Crypto-Jews". More recently, Evangelical Protestant Christians have opened missionary groups aimed at cultivating evangelical doctrine in Southwestern American communities where crypto-Judaism had survived.
According to a December 2008 study published in the American Journal of Human Genetics, 19.8 percent of modern Spaniards (and Portuguese) have DNA reflecting Sephardic Jewish ancestry, compared to 10.6 percent having DNA reflecting Moorish ancestors. The Sephardic result is in contradiction or not replicated in all the body of genetic studies done in Iberia and has been relativized by the authors themselves and questioned by Stephen Oppenheimer who estimate that much earlier migrations, 5,000 to 10,000 years ago from the Eastern Mediterranean might also have accounted for the Sephardic estimates. "They are really assuming that they are looking at this migration of Jewish immigrants, but the same lineages could have been introduced in the Neolithic". The same authors in also a recent study (October 2008) attributed most of those same lineages in Iberia and the Balearic Islands as of Phoenician origin. The rest of genetic studies done in Spain estimate the Moorish contribution ranging from 2.5/3.4% to 7.7%.
Recent genetic research, however, has shown that many Latinos of the American Southwest may be descended from Anusim (Sephardic Jews who converted to Roman Catholicism). Michael Hammer, a research professor at the University of Arizona and an expert on Jewish genetics, said that fewer than 1% of non-Semites, but more than four times the entire Jewish population of the world, possessed the male-specific "Cohanim marker" (which in itself is not necessarily carried by all Jews, but is prevalent among Jews claiming descent from hereditary priests), and 30 of 78 Latinos tested in New Mexico (38.5%) were found to be carriers. DNA testing of Hispanic populations also revealed between 10% and 15% of men living in New Mexico, south Texas and northern Mexico have a Y chromosome that traces back to the Middle East. There is no certainty that these lineages are Middle Eastern, as they could also be of earlier Phoenician and later North African influence. Tunisians also rank very high with the Y- chromosome marker that is related to Cohanim. There could be a North African connection for this as well. There is no specific Jewish DNA marker and with so much Moorish and Phoenician settlement in Spain one cannot tell the religion of the bearers’ ancestors.
In northern Mexico, Monterrey, the capital city of the state of Nuevo León, which shares a border with Texas, is said to contain descendants of Crypto-Jews. The church in Agualeguas, Nuevo León, Mexico indeed has Star of David windows beneath the Christian cross atop the domed roof. The state of Jalisco has several cities with large numbers of Anusim, mainly Guadalajara, Ciudad Guzmán, and Puerto Vallarta, although a steady influx of Ashkenazi Jews from Eastern Europe during the late 19th century and early to mid-20th century into Mexico City, Guadalajara, and Veracruz is also widely known.
In the Old Town area of Albuquerque, New Mexico, the San Felipe de Neri Catholic Church, built in 1793 to replace the original 1706 mission church, contains a Star of David on the left and right sides of the altar—evidence of the influence of Crypto-Jews in New Mexico. Many Jewish symbols can be found on cemetery headstones in Northern New Mexico, alongside Catholic crosses.
Today, there are about 40,000 Mexican Jews, both Ashkenazi and Sephardi. Researchers and historians say that number would rise considerably if Anusim (or Crypto-Jews) were included in those estimates.
Central and South America, the Caribbean
As in the American Southwest, in the department of Antioquia, Colombia, as well as in the greater Paisa region, many families also hold traditions and oral accounts of Jewish descent. In this population, Y chromosome genetic analysis has shown an origin of founders predominantly from "southern Spain but also suggest that a fraction came from northern Iberia and that some possibly had a Sephardic origin". The Medellín tradition of the marranada, where a pig is slaughtered, butchered and consumed on the streets of every neighborhood each Christmas has been interpreted as an annual affirmation of the rejection of Jewish law.
A safe haven destination for Sephardic Conversos during the Spanish Colony was Santa Cruz de la Sierra. In 1557 many Crypto-Jews joined Ñuflo de Chávez and were among the pioneers who founded the city. During the 16th century several Crypto-Jews that faced persecution from the Inquisition and local authorities in nearby Potosí, La Paz and La Plata also moved to Santa Cruz for it was the most isolated urban settlement and because the Inquisition did not bother the Conversos there for this frontier town was meant to be a buffer to the Portuguese and Guaraní raids that threatened the mines of Peru. Several of them settled in the city of Santa Cruz and its adjacent towns of Vallegrande, Postrervalle, Portachuelo, Terevinto, Pucarà, Bolivia, Cotoca and others.
Several of the oldest Catholic families in Santa Cruz are in fact of Jewish origin; some traces of Judaic practices are still alive among them and have also influenced the rest of the community. As recent as the 1920s, several families preserved seven-branched candle sticks and served dishes cooked with reminiscing kosher practices. It is still customary among certain old families to light candles on Friday at sunset and to mourn the deaths of dear relatives on the floor. After almost five centuries, some of the descendants of these families still acknowledge their Jewish origin, but practice Catholicism (in certain cases with some Jewish syncretism).
Some Crypto-Jews established in the outskirts of San José, Costa Rica since the 16th century. They passed as Catholics in public and practiced their Jewish rituals in privacy. In the town of Itzkazú (modern day Escazú) some Crypto-Jewish families could not achieve total secrecy of their condition and locals started to associate their rituals and unintelligible prayers in Hebrew as witchcraft. Since then, Escazú has been known in Costarrican folklore as the ¨city of the witches¨.
In Peru, conversos arrived at the time of the Spanish Conquest. At first, they had lived without restrictions because the Inquisition was not active in Peru at the beginning of the Viceroyalty. Then, with the advent of the Inquisition, New Christians began to be persecuted, and, in some cases, executed. In this period, these people were sometimes called "marranos", converts ("conversos"), and "cristianos nuevos" (New Christians) even if they had not been among the original converts from Judaism and had been reared as Catholics. The descendants of these Colonial Sephardic Jewish descent converts to Christianity settled mainly in the north of the Andes and of the high jungle of Peru, and they were assimilated to local people.
In addition to these communities, Roman Catholic-professing communities who are descendants of Crypto-Jews are said to exist in the Dominican Republic, Cuba, Jamaica, Puerto Rico and in various other Spanish-speaking countries of South America, such as Argentina, Venezuela, Chile and Ecuador. From these communities comes the proverb, "Catholic by faith, Jewish by blood".
All the above localities were former territories of either the Spanish or Portuguese Empires, where the Inquisition eventually followed and continued investigating Crypto-Jews who had settled there. The Inquisition endured longer in the colonies than it had in Spain itself.
- Dona Gracia Mendes Nasi was a 16th-century international banker who created an escape network that saved thousands of Crypto-Jews from the Inquisition. She was also a patron of (Jewish) writers, and a diplomat on behalf of her people, who also attempted to start a modern state of Israel.
- Luis de Carvajal was the governor of the state of Nuevo León, a northern Mexico province in which the restriction against immigration from conversos was relaxed in order to encourage migration to the frontier. He was responsible for bringing a significant group of crypto-Jewish conversos living in Portugal since the Expulsion of 1492.
- Luis de Carvajal el Mozo, was the nephew of Jose Luis Carvajal y de la Cueva, the only crypto-Jew of the Spanish colonial era whose memoirs have been preserved.
- Antonio Fernandez Carvajal was a Portuguese merchant in London; "like other Marranos in London, Carvajal prayed at the Catholic chapel of the Spanish ambassador, while simultaneously playing a leading role in the secret Jewish community, which met at the clandestine synagogue at Creechurch Lane."
- Some scholars of Judaic studies believe that Miguel de Cervantes may have been a crypto-Jew or of crypto-Jewish descent.
- Some scholars hold that Roderigo Lopez, a converso who fled from Portugal to England and became physician to Queen Elizabeth I, was a Crypto-Jew.

Not all of those who left Iberia were 'unconverted', which is to say that not all of the ethnic Jews who chose exile over commitment to their homeland led secret lives in the faith of their forebears. ... Some recovered their Judaism in exile; some continued to live in their Christian faith. It is not absolutely clear among which of the aforementioned groups we should place Dr Roderigo Lopez.
