Jewish ethnic divisions
|Part of a series on|
|Jews and Judaism|
Jewish ethnic divisions refers to a number of distinctive communities within the world's ethnically Jewish population. Although considered one single self-identifying ethnicity, there are distinctive ethnic divisions among Jews, most of which are primarily the result of geographic branching from an originating Israelite population, and subsequent independent evolutions.
As long ago as Biblical times, cultural and linguistic differences between Jewish communities, even within the area of Ancient Israel and Judea, are observed both within the Bible itself as well as from archeological remains. In more recent human history, an array of Jewish communities were established by Jewish settlers in various places around the Old World, often at great distances from one another resulting in effective and often long-term isolation from each other. During the millennia of the Jewish diaspora the communities would develop under the influence of their local environments; political, cultural, natural and populational. Today, manifestation of these differences among the Jews can be observed in Jewish cultural expressions of each community, including Jewish linguistic diversity, culinary preferences, liturgical practices, religious interpretations, as well as degrees and sources of genetic admixture.
Historical background 
Ancient Israel and Judah 
The full extent of the cultural, linguistic, religious or other differences among the Israelites in antiquity is unknown. Following the defeat of the Kingdom of Israel in the 720s BCE and the Kingdom of Judah in 586 BCE, the Jewish people became dispersed throughout much of the Middle East, especially in Egypt and North Africa to the west, as well as in Yemen to the south, and in Mesopotamia to the east. The Jewish population in Palestine was severely reduced by the Jewish-Roman Wars and by the later hostile policies of the Christian emperors, against non-Christians, but the Jews always retained a presence in the Levant. During this period, Paul Johnson writes: "Wherever towns survived, or urban communities sprang up, Jews would sooner or later establish themselves. The near-destruction of Palestinian Jewry in the second century turned the survivors of Jewish rural communities into marginal town-dwellers. After the Arab conquest in the seventh century, the large Jewish agricultural communities in Babylonia were progressively wrecked by high taxation, so that there too the Jews drifted into towns and became craftsmen, tradesmen, and dealers. Everywhere these urban Jews, the vast majority literate and numerate, managed to settle, unless penal laws or physical violence made it impossible."
In the early-Byzantine 6th century, there were 43 Jewish communities in Palestine. During the Islamic period and the intervening Crusades, there were 50 communities which included Jerusalem, Tiberias, Ramleh, Ashkelon, Caesarea, and Gaza. During the early Ottoman Period of the 14th century there were 30 communities which included Haifa, Shechem, Hebron, Ramleh, Jaffa, Gaza, Jerusalem, and Safed. The most dominant location became Safed which reached a population of 30,000 Jews by end of the 16th century, after the expulsion of Sephardim from Iberia, a century earlier. The 16th century saw many Ashkenazi Kabbalists drawn to the mystical aura and teachings of the Jewish holy city. Johnson notes that in the Arab-Muslim territories, which included most of Spain, all of North Africa, and the Near East south of Anatolia in the Middle Ages, the Jewish condition was easier as a rule, than it was in Europe.
Over the centuries following the Crusades and Inquisition, Jews from around the world began emigrating in increasing numbers. Upon arrival, these Jews adopted the customs of the Mizrahi and Sephardi communities into which they moved. With Baron von Rothschild's philanthropic land purchases and subsequent efforts to turn Palestine into a verdant Jewish homeland, and the subsequent rise of Zionism, a flood of Ashkenazi immigration brought the Jewish population of the region to several hundred thousand.
Following the loss of their second revolt against the Romans and their exile by them, at the height of the empire in the 2nd century, Jewish communities similarly could be found in nearly every notable center throughout it, as well as scattered communities found in centers beyond the Empire's borders in northern Europe, in eastern Europe, in southwestern Asia, and in Africa. Farther to the east along trade routes, Jewish communities could be found throughout Persia and in empires even farther east including in India and China. In the Early Middle Ages of the 6th to 11th centuries, the Radhanites traded along the overland routes between Europe and Asia earlier established by the Romans, dominated trade between the Christian and the Islamic worlds, and used a trade network that covered most areas of Jewish settlement.
In the middle Byzantine period, the khan of Khazaria in the northern Caucasus and his court converted to Judaism, partly in order to maintain neutrality between Christian Byzantium and the Islamic world. This event forms the framework for Yehuda Halevi's work 'The Kuzari' (c.1140), but how much these traces of Judaism within this group survived the collapse of the Khazar empire is a matter of scholarly debate.
In western Europe, following the collapse of the Western Roman Empire in 476, and especially after the re-orientation of trade caused by the Moorish conquest of Iberia in the early 8th century, communications between the Jewish communities in northern parts of the former western empire became sporadic. At the same time, rule under Islam, even with dhimmi status, resulted in freer trade and communications within the Muslim world, and the communities in Iberia remained in frequent contact with Jewry in North Africa and the Middle East, but communities further afield, in central and south Asia and central Africa, remained more isolated, and continued to develop their own unique traditions. For the Sephardim in Spain, it resulted in a "Hebrew Golden Age" in the 10th to 12th centuries. The 1492 expulsion from Spain by the Catholic Monarchs however, made the Sephardic Jews hide and disperse to France, Italy, England, the Netherlands, parts of what is now northwestern Germany, and to other existing communities in Christian Europe, as well as to those within the Ottoman Empire, to the Maghreb in North Africa and smaller numbers to other areas of the Middle East, and eventually to the Americas in the early 17th century.
In northern and Christian Europe during this period, financial competition developed between the authority of the Pope in Rome and nascent states and empires. This dynamic, with the Great Schism, recurrent fervid anti-Christian religious Crusades, Episcopal Inquisition and later protestations and wars between Christians themselves, caused repeated periods and occurrences of persecution against the established Jewish minority in "Ashkenaz" in modern Hebrew means Germanic Jews and with Ancient Hebrew it included the areas that are now northern France, Germany and Switzerland—masses of Jews began to move further to the east. There, they were welcomed by the king of Poland, and with Lithuania, grew greatly, and relatively flourished to the end of the 18th century. In western Europe, the conditions for Jewry differed between the communities within the various countries and over time, depending on background conditions. With both pull and push factors operating, Ashkenazi emigration to the Americans would increase in the early 18th century with German-speaking Askenazi Jews, and end with a tidal wave between 1880 and the early 20th century with Yiddish-speaking Ashkenazim, as conditions in the east deteriorated under the failing Russian Empire. With the Holocaust and the destruction of most European Jewry, North America would hold the majority of world Jewry.
Modern divisions 
Historically, Jews have been identified into two major groups: the Ashkenazim, or "Germanics" ("Ashkenaz" meaning "Germany" in Medieval Hebrew, denoting their Central European base), and the Sephardim, or "Hispanics" ("Sefarad" meaning "Hispania" or "Iberia" in Hebrew, denoting their Spanish and Portuguese base). The far more recent term Mizrahim, or "Easterners" ("Mizrach" being "East" in Hebrew) to include Middle Eastern and North African Jews, constitutes a third major group to some, following the partition of Palestine, their often-forced migration, and the re-establishment of their communities in Israel.
Smaller Jewish groups include the Georgian Jews and Mountain Jews from the Caucasus; Indian Jews including the Bene Israel, Bnei Menashe, Cochin Jews and Bene Ephraim; the Romaniotes of Greece; the ancient Italian Jewish community; the Teimanim from the Yemen and Oman; various African Jews, including most numerously the Beta Israel of Ethiopia; the Bukharan Jews of Central Asia; and Chinese Jews, most notably the Kaifeng Jews, as well as various other distinct but now extinct communities.
The divisions between all these groups are rough and their boundaries aren't solid. The Mizrahim for example, are a heterogeneous collection of North African and Middle Eastern Jewish communities which are often as unrelated to each other as they are to any of the earlier mentioned Jewish groups. In modern usage, however, the Mizrahim are also termed Sephardi due to similar styles of liturgy, despite independent evolutions from Sephardim proper. Thus, among Mizrahim there are Iranian Jews, Iraqi Jews, Egyptian Jews, Sudanese Jews, Tunisian Jews, Algerian Jews, Moroccan Jews, Lebanese Jews, Kurdish Jews, Libyan Jews, Syrian Jews, and various others. The Yemenite Jews ("Teimanim") from Yemen and Oman are sometimes included, although their style of liturgy is unique and they differ in respect to the admixture found among them to that found in Mizrahim. Additionally, there is a difference between the pre-existing Middle Eastern and North African Jewish communities as distinct from the descendants of those Sephardi migrants who established themselves in the Middle East and North Africa after the expulsion of the Jews from Spain by the Catholic Monarchs in 1492, and a few years later from the expulsion decreed in Portugal.
Despite this diversity, Ashkenazi Jews represent the bulk of modern Jewry, estimated at between 70% and 80% of all Jews worldwide; prior to World War II and the Holocaust however, it was 90%. While Ashkenazim developed in Europe, their massive emigration from Europe for better opportunities, and during periods of civil strife and warfare, they also became the overwhelming majority of Jews in the New World continents and countries, which previously were without native European or Jewish populations. These include the United States, Canada, United Kingdom, Argentina, Australia, Brazil and South Africa, but with Venezuela and Panama being exceptions since Sephardim still compose the majority of the Jewish communities in these two countries. In France, more recent Sephardi Jewish immigrants from North Africa and their descendants now outnumber the pre-existing Ashkenazim. Only in Israel is the Jewish population representative of all groups, a melting pot independent of each group's proportion within the overall world Jewish population.
Genetic studies of DNA 
Despite the evident diversity displayed by the world's distinctive Jewish populations, both culturally and physically, genetic studies have demonstrated most of these to be genetically related to one another, having ultimately originated from a common ancient Israelite population that underwent geographic branching and subsequent independent evolutions.
A study published by the National Academy of Sciences stated that "The results support the hypothesis that the paternal gene pools of Jewish communities from Europe, North Africa, and the Middle East descended from a common Middle Eastern ancestral population, and suggest that most Jewish communities have remained relatively isolated from neighboring non-Jewish communities during and after the Diaspora." Researchers expressed surprise at the remarkable genetic uniformity they found among modern Jews, no matter where the diaspora has become dispersed around the world.
Moreover, DNA tests have demonstrated substantially less inter-marriage in most of the various Jewish ethnic divisions over the last 3,000 years than in other populations. The findings lend support to traditional Jewish accounts accrediting their founding to exiled Israelite populations, and counters theories that many or most of the world's Jewish populations were founded by entirely gentile populations that adopted the Jewish faith, as in the notable case of the historic Khazars. Although groups such as the Khazars could have been absorbed into modern Jewish populations — in the Khazars' case, absorbed into the Ashkenazim — it is unlikely that they formed a large percentage of the ancestors of modern Ashkenazi Jews, and much less that they were the genesis of the Ashkenazim.
Even the archetype of Israelite-origin is also beginning to be reviewed for some Jewish populations amid newer studies. Previously, the Israelite origin identified in the world's Jewish populations was attributed only to the males who had migrated from the Middle East and then forged the current known communities with "the women from each local population whom they took as wives and converted to Judaism". Research in Ashkenazi Jews has suggested that, in addition to the male founders, significant female founder ancestry might also derive from the Middle East, with about 40% of the current Ashkenazi population descended matrilineally from just four women, or "founder lineages", that were "likely from a Hebrew/Levantine mtDNA pool" originating in the Near East in the 1st and 2nd centuries CE.
Points in which Jewish groups differ is largely in the source and proportion of genetic contribution from host populations. As examples, the Teimanim differ from other Mizrahim, as well as from Ashkenazim, in the proportion of sub-Saharan African gene types which have entered their gene pools. Among Yemenites, the average stands at 35% lineages within the past 3,000 years. Yemenite Jews, as a traditionally Arabic-speaking community of local Yemenite and Israelite ancestries, are included within the findings, though they average a quarter of the frequency of the non-Jewish Yemenite sample. In Ashkenazi Jews, the proportion of male indigenous European genetic admixture amounts to around 0.5% per generation over an estimated 80 generations, and a total admixture estimate around 12.5%. The only exception to this amongst Jewish communities is in the Beta Israel (Ethiopian Jews); a 1999 genetic study came to the conclusion that "the distinctiveness of the Y-chromosome haplotype distribution of Beta Israel Jews from conventional Jewish populations and their relatively greater similarity in haplotype profile to non-Jewish Ethiopians are consistent with the view that the Beta Israel people descended from ancient inhabitants of Ethiopia who converted to Judaism." Another 2001 study did, however, find a possible genetic similarity between 11 Ethiopian Jews and 4 Yemenite Jews from the population samples.
DNA analysis further determined that modern Jews of the priesthood tribe — "Cohanim" — share a common ancestor dating back about 3,000 years. This result is consistent for all Jewish populations around the world. The researchers estimated that the most recent common ancestor of modern Cohanim lived between 1000 BCE (roughly the time of the Biblical Exodus) and 586 BCE, when the Babylonians destroyed the First Temple. They found similar results analyzing DNA from Ashkenazi and Sephardi Jews. The scientists estimated the date of the original priest based on genetic mutations, which indicated that the priest lived roughly 106 generations ago, between 2,650 and 3,180 years ago depending whether one counts a generation as 25 or 30 years.
Geographic distribution 
Because of the independence of local communities, Jewish ethnicities, even when they circumscribe differences in liturgy, language, cuisine and other cultural accoutrements, are more often a reflection of geographic and historical isolation from other communities. It is for this reason that communities are referred to by referencing the historical region in which the community cohered when discussing their practices, regardless of where those practices are found today.
The smaller groups number in the hundreds to tens of thousands, with the Georgian Jews (also known as Gruzinim or Qartveli Ebraeli) and Beta Israel being most numerous at somewhat over 100,000 each. Many members of these groups have now emigrated from their traditional homelands, largely to Israel. For example, only about 10 percent of the Gruzinim remain in Georgia.
A brief description of the extant communities, by the geographic regions with which they are associated, is as follows:
- Ashkenazim are the descendants of Jews who migrated into northern France and Germany around 800–1000, and later into Eastern Europe. Ashkenazim comprise the overwhelming majority of Jews, with approximately 80 percent of the Jewish total (prior to the Holocaust, they were an even greater percentage of world Jewry). Even among the Ashkenazim there are a number of major subgroups:
- Western Jews, stemming from northern France, from the Lowlands, historical Germany, the Austro-Hungarian Empire, Switzerland, and Scandinavia, originally spoke Western Yiddish, which had less Slavic influence than other Yiddish dialects. By the early 20th century, Yiddish was in decline in this population, and assimilation was proceeding rapidly. In Israel, a sometimes derogatory term for these Jews (also applied to Austrian Oberlander Jews), is Yekkes.
- Oberlander, originating in the Oberland region of Hungary and the district surrounding Bratislava in Slovakia, originally spoke western Yiddish. In modern times before the Holocaust, many Oberlander Jews migrated to urban centers of the Austro-Hungarian Empire and adopted German or Hungarian as their first language.
- Polish Jews, from Congress Poland.
- (Galitzianers) from southern Poland and western Ukraine
- Hungarians from Hungary, Slovakia and parts of Romania
- Lithuanian Jews ("Litvak Jews"), (North-eastern Europe)
- Southeastern, predominantly from Ukraine, Moldova and Romania
- Romaniotes are Greek-speaking Jews from the Balkans that lived there from the Hellenistic era until today.
- Sephardim are Jews whose ancestors lived in Spain or Portugal, where they lived for possibly as much as two millennia before being expelled in 1492 by the Catholic Monarchs (see Alhambra decree); they subsequently migrated to the Islamic North African Maghreb and Ottoman Empire (both at the time considered safe havens for Jews). In the Ottoman Empire the Sephardim mostly settled in the European portion of the Empire, and mainly in the major cities such as Constantinople, Thessaloniki, Sarajevo, Monastir – modern-day Bitola in the Republic of Macedonia, Sofia and other cities in Bulgaria, and Bursa. Prior to World War II, Thessaloniki, which today is the second largest city in Greece, had a large and flourishing Sephardic community of approximately 50,000. Another was the community of Maltese Jews in Malta. Others settled in Italy and the Netherlands, and Latin America. Among those who settled in the Netherlands, some would again relocate to the United States, establishing the country's first organized community of Jews and erecting the United States' first synagogue. Other Sephardim remained in Spain and Portugal as anusim (forced converts to Catholicism), which would also be the fate for those who had migrated to Spanish and Portuguese ruled Latin America.
- Bené Roma or Italkim represent many of the Italian Jews, though Italy also has both Ashkenazic and Sephardic communities.
- Chuts were Dutch Jews, observing an amalgam of Ashkenazi and Sephardi customs, living in London, although this community has almost completely been lost to history.
- San Nicandro Jews – A group of mid-20th century converts from Italy.
The Caucasus and the Crimea 
- Qartveli Ebraeli, or Gruzinim, are Georgian-speaking Jews from Georgia in the Caucasus.
- Juhurim are mountain Jews mainly from Daghestan and Azerbaijan in the eastern Caucasus.
- Krymchaks and Karaim are Turkic-speaking Jews of the Crimea and Eastern Europe. The Krymchaks practice Rabbinic Judaism, while the Karaim practice Karaite Judaism. Whether they are primarily the descendants of Israelite Jews who adopted Turkic language and culture, or the descendants of Turkic converts to Judaism, is still debated, although the question is irrelevant as far as Jewish law is concerned, according to which they are Jews, regardless of whether by Israelite descent or by conversion.
- The 750 Armenian Jews today comprise a minuscule remnant of an ancient population dating back over 2,500 years, and once numbering as many as 100,000.
- Subbotniks are a dwindling group of Jews from Azerbaijan and Armenia, whose ancestors were Russian peasants who converted to Judaism for unknown reasons in the 19th century.
North Africa and the Middle East 
Jews originating from Muslim lands are generally called by the catch-all term Mizrahi Jews, more precise terms for particular groups are:
- Iraqi Jews are descendants of the Jews who have lived in Mesopotamia since the time of the Assyrian conquest of Samaria
- Kurdish Jews from Kurdistan, as distinct from the Persian Jews of central and eastern Persia, as well as from the lowland Iraqi Jews of Mesopotamia.
- Persian Jews from Iran (commonly called Parsim in Israel, from the Hebrew) have a 2700-year history. One of the oldest Jewish communities of the world, Persian Jews constitute the largest Jewish community in the Middle East outside Israel.
- Yemenite Jews (called Temanim, from the Hebrew) are Oriental Jews whose geographic and social isolation from the rest of the Jewish community allowed them to develop a liturgy and set of practices that are significantly distinct from other Oriental Jewish groups; they themselves comprise three distinctly different groups, though the distinction is one of religious law and liturgy rather than of ethnicity.
- Palestinian Jews are Jewish inhabitants of Palestine throughout certain periods of Middle Eastern history. After the modern State of Israel was born, nearly all native Palestinian Jews became citizens of Israel, and the term "Palestinian Jews" largely fell into disuse.
- Egyptian Jews are generally Jews thought to have descended from the great Jewish communities of Hellenistic Alexandria, mixed with many more recent groups of immigrants. These include Babylonian Jews following the Muslim conquest; Jews from Palestine following the Crusades; Sephardim following the expulsion from Spain; Italian Jews settling for trading reasons in the 18th and 19th centuries; and Jews from Aleppo in the late 19th and early 20th centuries.
- Sudanese Jews are Jewish community that lived in Sudan, and was concentrated in the capital Khartoum, they were mainly of Sephardic background, who had constructed a synagogue and a Jewish school.
- Lebanese Jews are the Jews that lived around Beirut. After the Lebanese Civil War, the community's emigration appears to have been completed; few remain in Lebanon today.
- Omani Jews are the early Jewish community of Sohar. They are thought to be descendants of Ishaq bin Yahuda, a Sohari merchant around the first millennium. This community is believed to have disappeared by 1900.
- Syrian Jews are generally divided into two groups: those who inhabited Syria from the time of King David (1000 BC), and those who fled to Syria after the Spanish Inquisition (1492), at the invitation of the Ottoman sultan. There were large communities in both Aleppo and Damascus for centuries. In the early 20th century, a large percentage of Syrian Jews emigrated to the U.S., South America, and Israel. Today, there are almost no Jews left in Syria. The largest Syrian-Jewish community is located in Brooklyn, New York, and is estimated at 40,000.
Sub-Saharan Africa 
- Abayudaya of Uganda
- Beta Israel or Falashim of Ethiopia, tens of thousands migrated to Israel during Operation Moses (1984), Operation Sheba (1985) and Operation Solomon (1991).
- Descendants of the Jews of the Bilad el-Sudan (West Africa). Jews whose ancestry was derived from the communities that once existed in the Ghana, Mali, and Songhay Empire. Anusim in and around Mali who descend from Jewish migrations from North Africa, East Africa, and Spain.
- The House of Israel, several hundred Sefwi tribesmen in Ghana
- The emergent Igbo Jewish community of Nigeria, perhaps as many as 30,000 strong (although many of them maintain a belief in the Messiahship of Jesus and adhere to basic tenets of Christianity that are mutually exclusive of normative Judaism).
- The Lemba people in Malawi which number as many as 40,000. This group claims descent from ancient Israelite tribes that migrated down to southern Africa via southern Arabia. Genetic testing has partially upheld these claims. Many are now moving toward practising normative Judaism.
- The Jews of Rusape, Zimbabwe, also claim descent from ancient Jewish communities. Although they held a belief in Jesus as a prophet, the community is now shifting towards mainstream Judaism and abandoning their belief in Jesus. They are not considered Jews by most of the Jewish world.
- South African Jews make up the largest community of Jews in Africa. Dutch Sephardic Jews were among the first permanent residents of Cape Town when the city was founded by the VOC in 1652. Today, however, most of South Africa's Jews are Ashkenazi and, in particular, of Lithuanian descent.
- Communities also existed in São Tomé e Príncipe, descended from Portuguese Jewish youths expelled during the Inquisition.
South, East, and Central Asia 
- Bene Israel are the Jews of Mumbai, India, most of whom now reside in Israel.
- Bukharan Jews are Jews from Central Asia. They get their name from the former Central Asian Emirate of Bukhara, which once had a large Jewish population.
- Cochin Jews are also Indian Jews from south-western India, most of whom also now reside in Israel. Included among these are the Paradesi Jews.
- Syrian Malabar Nasranis (or Nasranis) are Judeo-Christians in south-western India who trace their origins to early Jewish settlers there. They are Jews by genealogy and descent and related to the Cochin Jews as well as to Ashkenazi Jews as proved recently by DNA studies on the community. During the Portuguese Inquisition many Paradesi (Sephardic) and Malabari Jews assimilated into the Nasrani community. Some from the community have also been reported to carry the Cohen gene marker, Cohen Modal Haplotype, indicating Aaronic descent for some.
- Baghdadi Jews  Those Jews came from Iraq, Iran, Afghanistan and Arab countries who settled in India in 18th century.
- Bnei Menashe. A group of Jews living in Manipur and Mizoram in north-eastern India, claiming descent from the dispersed Biblical Tribe of Menasseh.
- Bene Ephraim, the Telugu-speaking Jews of Kottareddipalem in Andhra Pradesh, India.
- Chinese Jews: most prominent were the Kaifeng Jews, an ancient Jewish community in China, descended from merchants living in China from at least the era of the Tang dynasty. Today functionally extinct, although several hundred descendants have recently begun to explore and reclaim their heritage.
- Pakistani Jews: There was a thriving Jewish community in Pakistan particularly around the city of Karachi but also in other urban areas up north such as in Peshawer, Rawalpindi and Lahore. The origins of the Jewish community was mixed with some being Bene Israel, Bukharan Jews and Baghdadi Jews. In the late 1980s and 1990s, Jewish refugees from Iran had also came via Pakistan's Balochistan province and reached Karachi until the Iranian government closed down the operation. Most of Pakistan's Jewish community has not relocated to Israel and Pakistan's Jewish population is believed to number around 700.
- Afghan Jews: Records of a Jewish population in Afghanistan go back to the 7th century. Before the arrival of Islam in Kabul, Kabul and Gandhara were trading places for Jewish merchants. It is also believed that a large Jewish culture was present during the Greco-Buddhism era. After the arrival of Mahmud of Ghazni and other Mughal leaders, Jewish culture demised and gradually vanished. The theory of Pashtun descent from Israelites—that the Pashtun people are related to the Ten Lost Tribes—continues to have both supporters and detractors.
Most Jewish communities in the Americas are descendants of Jews who found their way there at different times of modern history. The first Jews to settle in the Americas were of Spanish/Portuguese origin. Today, however, the great majority of recognized Jews on both the North American and South American continents are Ashkenazi, particularly among Jews in the United States. There are also Mizrahim and other diaspora groups represented (as well as mixes of any or all of these) as mentioned above. Some unique communities associated with the Americas include:
- Hispanic Crypto-Jews are the descendants of Sephardi immigrants to the New World escaping the Spanish Inquisition in Spain and Portugal. Following the establishment of the Inquisition in the Iberian colonies, again they hid their ancestry and beliefs. Their numbers are difficult to ascertain as most are at least nominally Catholic, having been forcefully converted, converted for forms sake, or married into the religion. Collectively, people of Jewish descent in Latin America could surpass the millions. Most would be of mixed ancestry, although a few claim some communities may have been able to maintain a degree of endogamy (marrying only other Crypto-Jews) throughout the centuries. They may or may not consider themselves Jewish, some may continue to preserve some of their Jewish heritage in secrecy, many others may not even be aware of it. The majority would not be halakhically Jewish, but small numbers of various communities have formally returned to Judaism over the past decade, legitimizing their status as Jews. See also Anusim.
- Amazonian Jews are the mixed descendants of Moroccan Jewish communities in Belém, Santarém, Manaus, Iquitos, Tarapoto and many river villages in the Amazon basin in Brazil and Peru.
- Iquitos Jews are the "accidental" descendants of mostly Moroccan Jewish traders and tappers who arrived in the Peruvian Amazon city of Iquitos during the rubber boom of the 1880s. Since their Jewish descent was patrilineal (Jewish traders had been all males who coupled up with local mestizo or Amerindian females), their Jewishness is not recognised according to halakha. An enduring casta system stemming from the colonial period has resulted in virtually no interaction between the Iquitos Jews and the small, mostly Ashkenazi Jewish, population concentrated in Lima (under 3,000) who are integrated into Lima's elite white minority. Thanks to efforts made by Israeli outreach programmes, some have formally returned to Judaism, made aliyah and now live in Israel.
- B'nai Moshe are converts to Judaism originally from Trujillo, Peru. They are also known as Inca Jews, a name derived from the fact that they can trace indigenous Amerindian descent, as most are mestizos (persons of both Spanish and Amerindian descent) though none with any known ancestors from other Jewish communities. Again, there is no interaction between Peru's small Ashkenazi population and the Inca Jews. At the neglect of the Ashkenazi community, the conversions were conducted under the auspices of the Chief Rabbinate of Israel. Most have made aliyah and now live in Israel, while a few hundred more of the same community are awaiting conversions.
- Veracruz Jews are a recently emergent community of Jews in Veracruz, Mexico. Whether they are gentile converts to Judaism or descendants of anusim returning to Judaism is speculative. Most claim they descend from anusim.

By the time the State of Israel was proclaimed, the majority of Jews in the state and the region were Ashkenazi. Following the declaration of the state, a flood of Jewish migrants and refugees entered Israel from the Arab world and the Muslim world in general. Most were Sephardim and Mizrahim, which included Jews from the Maghreb, Yemenite Jews, Bukharan Jews, Persian Jews, Iraqi Jews, Kurdish Jews, and smaller communities, principally from Libya, Egypt and Turkey. More recently, other communities have also arrived including Ethiopian Jews and Indian Jews. Because of the relative homogeneity of Ashkenazic Jewry, especially by comparison to the diversity of the many smaller communities, over time in Israel, all Jews from Europe came to be called "Ashkenazi" in Israel, whether or not they had any connection with Germany, while Jews from Africa and Asia have come to be called "Sephardi", whether or not they had any connection with Spain. One reason is that most African and Asian Jewish communities use the Sephardic prayer ritual and abide by the rulings of Sephardic rabbinic authorities, and therefore consider themselves to be "Sephardim" in the broader sense of "Jews of the Spanish rite", though not in the narrower sense of "Spanish Jews". Similarly "Ashkenazim" has the broader sense of "Jews of the German rite".
The founders of modern Israel, mostly Ashkenazi Jews, are often said to have believed themselves superior to these new arrivals. With higher degrees of Western-standard education, they were better positioned to take full advantage of the emerging Western-style liberal democracy and Western mode of living which they themselves had established as the cultural norm in Palestine during the pre-state era.
Cultural and/or "racial" biases against the newcomers were compounded by the fledgling state's lack of financial resources and inadequate housing to handle the massive population influx. Thus, hundreds of thousands of new Sephardic immigrants were sent to live in tent cities in outlying areas. Sephardim (in its wider meaning) were often victims of discrimination, and were sometimes called schwartze (meaning "black" in Yiddish).
Worse than housing discrimination was the differential treatment accorded the children of these immigrants, many of whom were tracked by the largely European education establishment into dead-end "vocational" schools, without any real assessment of their intellectual capacities. Mizrahi Jews protested their unfair treatment, and even established the Israeli Black Panthers movement with the mission of working for social justice.
The effects of this early discrimination still linger a half-century later, as documented by the studies of the Adva Center, a think tank on social equality, and by other Israeli academic research (cf., for example, Tel Aviv University Professor Yehuda Shenhav's article in Hebrew documenting the gross underrepresentation of Sephardic Jewry in Israeli high school history textbooks. Every Israeli prime minister has been Ashkenazi, although Sephardim and Mizrahim have attained the (ceremonial) presidency and other high positions. The student bodies of Israel's universities remain overwhelmingly European in origin, despite the fact that roughly half the country's population is non-European. And the tent cities of the 1950s morphed into so-called "development towns". Scattered over border areas of the Negev Desert and the Galilee, far from the bright lights of Israel's major cities, most of these towns never had the critical mass or ingredients to succeed as places to live, and they continue to suffer from high unemployment, inferior schools, and chronic brain drain.
While the Israeli Black Panthers no longer exist, the Mizrahi Democratic Rainbow Coalition and many other NGOs carry on the struggle for equal access and opportunity in housing, education, and employment for the country's underprivileged populace – still largely composed of Sephardim and Mizrahim, joined now by newer immigrants from Ethiopia and the Caucasus Mountains.
Intermarriage of all these regathered Jewish ethnic groups was initially uncommon, due in part to distances of each group's settlement in Israel, and cultural and/or "racial" biases. In recent generations, however, the barriers were lowered by state sponsored assimilation of all the Jewish ethnic groups into a common Sabra (native-born Israeli) identity which facilitated extensive "mixed-marriages".
