. By conservative and orthodox philosophies, a person can be considered a Jew only if his or her mother was Jewish (meaning, more specifically, either matrilineal descent from a female believed to be present at Mt. Sinai when the ten commandments were given, or else descent from a female who was converted to Judaism before the birth of her children), or if he or she has personally converted to Judaism. This means that a person can be Ashkenazi but not considered a Jew by some of those within the Jewish communities, making the term "Ashkenazi" more applicable as broad ethnicity which evolved from the practice of Judaism in Europe.

, or religious law, and different interpretations of law. Different groups of religious Jews in different geographic areas historically adopted different customs and interpretations. On certain issues, Orthodox Jews are required to follow the customs of their ancestors, and do not believe they have the option of picking and choosing. For this reason, observant Jews at times find it important for religious reasons to ascertain who their household's religious ancestors are in order to know what customs their household should follow. These times include, for example, when two Jews of different ethnic background marry, when a non-Jew converts to Judaism and determines what customs to follow for the first time, or when a lapsed or less observant Jew returns to traditional Judaism and must determine what was done in his or her family's past. In this sense, "Ashkenazic" refers both to a family ancestry and to a body of customs binding on Jews of that ancestry.

, most Jews prayed in liturgical Ashkenazi Hebrew, and spoke Yiddish in their secular lives.

But with modernization, Yiddishkeit now encompasses not just Orthodoxy and Hasidism, but a broad range of movements, ideologies, practices, and traditions in which Ashkenazi Jews have participated and somehow retained a sense of Jewishness. Although a far smaller number of Jews still speak Yiddish, Yiddishkeit can be identified in manners of speech, in styles of humor, in patterns of association.

Contemporary population migrations have contributed to a reconfigured Jewishness among Jews of Ashkenazi descent that transcends Yiddishkeit and other traditional articulations of Ashkenazi Jewishness. As Ashkenazi Jews moved away from Eastern Europe, settling mostly in Israel, North America, and other English-speaking areas, the geographic isolation that gave rise to Ashkenazim has given way to mixing with other cultures, and with non-Ashkenazi Jews who, similarly, are no longer isolated in distinct geographic locales.

and Eastern Europe. The result is a pluralistic Jewish community that still has some distinct elements of both Ashkenazi and Sephardic culture. But in France, it is becoming much more difficult to sort out the two, and a distinctly French Jewishness has emerged.

By ethnicity

In an ethnic sense, an Ashkenazi Jew is one whose ancestry can be traced to the Jews of Central and Eastern Europe. For roughly a thousand years, the Ashkenazim were a reproductively isolated population in Europe, despite living in many countries, with little inflow or outflow from migration, conversion, or intermarriage with other groups, including other Jews. Human geneticists have identified genetic variations that have high frequencies among Ashkenazi Jews, but not in the general European population. This is true for patrilineal markers (Y-chromosome haplotype

s) as well as for matrilineal markers (mitotypes

).

Since the middle of the 20th century, many Ashkenazi Jews have intermarried, both with members of other Jewish communities and with people of other nations and faiths, while some Jews have also adopted children from other ethnic groups or parts of the world and raised them as Jews. Conversion to Judaism, rare for nearly 2,000 years, has become more common.

A 2006 study found Ashkenazi Jews to be a clear, relatively homogeneous genetic subgroup. Strikingly, regardless of the place of origin, Ashkenazi Jews can be grouped in the same genetic cohort — that is, regardless of whether an Ashkenazi Jew's ancestors came from Poland, Russia, Hungary, Lithuania, or any other place with a historical Jewish population, they belong to the same ethnic group. The research demonstrates the endogamy of the Jewish population in Europe and lends further credence to the idea of Ashkenazi Jews as an ethnic group. Moreover, though intermarriage among Jews of Ashkenazi descent has become increasingly more common, many Ultra-Orthodox Jews, particularly members of Hasidic or Hareidi sects, continue to marry exclusively fellow Ashkenazi Jews. This trend keeps Ashkenazi genes prevalent and also helps researchers further study the genes of Ashkenazi Jews with relative ease. It is noteworthy that these Ultra-Orthodox Jews often have extremely large families.

Realignment in Israel

In Israel, the term Ashkenazi is now used in ways that have nothing to do with its original meaning; it is often applied to all Jews of European background living in Israel, including sometimes for those whose ethnic background is actually Sephardic. Jews of any non-Ashkenazi background, including Mizrahi, Yemenite, Kurdish and others who have no connection with the Iberian Peninsula

Iberian Peninsula

The Iberian Peninsula , sometimes called Iberia, is located in the extreme southwest of Europe and includes the modern-day sovereign states of Spain, Portugal and Andorra, as well as the British Overseas Territory of Gibraltar...

, have similarly come to be lumped together as Sephardic. Jews of mixed background are increasingly common, partly because of intermarriage between Ashkenazi and non-Ashkenazi, and partly because many do not see such historic markers as relevant to their life experiences as Jews.

matters. In this respect, a religiously Ashkenazi Jew is an Israeli who is more likely to support certain religious interests in Israel, including certain political parties. These political parties result from the fact that a portion of the Israeli electorate votes for Jewish religious parties; although the electoral map changes from one election to another, there are generally several small parties associated with the interests of religious Ashkenazi Jews. The role of religious parties, including small religious parties which play important roles as coalition members, results in turn from Israel's composition as a complex society in which competing social, economic, and religious interests stand for election to the Knesset

ic learning began to emerge and assert its authority over Jewish life throughout the diaspora. Rabbinic Judaism created a religious mandate for literacy, requiring all Jewish males to learn Hebrew and read from the Torah. It has been suggested that this mandate led to a higher literacy rate for Jewish minorities in both Christian and Islamic lands compared to the majority of gentiles, a result which gave these Jews a comparative advantage in urban commercial and financial roles which, to some extent, may explain their relative prevalence in these fields at the time.

After the Islamic conquest of the Middle East and North Africa, new opportunities for trade and commerce opened between the Middle East and Western Europe. The vast majority of Jews now lived in Islamic lands. Urbanization, trade, and commerce within the Islamic world allowed Jews, as a highly literate people, to abandon farming and live in cities, engaging in occupations where they could use their skills. The influential, sophisticated, and well organized Jewish community of Mesopotamia, now centered in Baghdad, became the center of the Jewish world. In the Caliphate of Baghdad, Jews took on many of the financial occupations that they would later hold in the cities of Ashkenaz. Jewish traders from Baghdad began to travel to the west, renewing Jewish life in the western Mediterranean region. They brought with them Rabbinic Judaism and Babylonian Talmud

The answer to why there was so little assimilation of Jews in Eastern Europe for so long would seem to lie in part in the probability that the alien surroundings in Eastern Europe were not conducive, though contempt did not prevent some assimilation. Furthermore, Jews lived almost exclusively in shtetls, maintained a strong system of education for males, heeded rabbinic leadership, and scorned the life-style of their neighbors; and all of these tendencies increased with every outbreak of antisemitism.

. Ironically, most people with this surname hail from within Sephardic communities, particularly from the Syrian Jewish community. The Sephardic carriers of the surname would have some Ashkenazi ancestors since the surname was adopted by families who were initially of Ashkenazic origins who move to Sephardi countries and joined those communities. Ashkenazi would be formally adopted as the family surname having started off as a nickname imposed by their adopted communities. Some have shortened the name to Ash.

The theory that the majority of Ashkenazi Jews are the descendants of the non-Semitic converted Khazars was advocated by various racial theorists and antisemitic sources in the late-19th and 20th centuries, especially following the publication of Arthur Koestler

Notable Ashkenazim

Ashkenazi Jews have a noted history of achievement in western societies. They have won a large number of the Nobel awards. In those societies where they have been free to enter any profession, they have a record of high occupational achievement, entering professions and fields of commerce where higher education is required. For example, during the 20th century in the United States, Ashkenazi Jews represented approximately 3% of the population, but won 27% of the US Nobel Prize

Genetic origins

Efforts to identify the origins of Ashkenazi Jews through DNA analysis began in the 1990s. Like most DNA studies of human migration patterns, the earliest studies focused on two segments of the human genome, the Y-chromosome

Male lineages: Y-chromosomal DNA

A study of haplotypes of the Y-chromosome, published in 2000, addressed the paternal origins of Ashkenazi Jews. Hammer et al. found that the Y-chromosome

Y chromosome

of Ashkenazi and Sephardic Jews contained mutations that are also common among Middle Eastern peoples, but uncommon in the general European population. This suggested that the male ancestors of the Ashkenazi Jews could be traced mostly to the Middle East. The proportion of male genetic admixture

Genetic admixture occurs when individuals from two or more previously separated populations begin interbreeding. Admixture results in the introduction of new genetic lineages into a population. It has been known to slow local adaptation by introducing foreign, unadapted genotypes...

in Ashkenazi Jews amounts to less than 0.5% per generation over an estimated 80 generations, with "relatively minor contribution of European Y chromosomes to the Ashkenazim," and a total admixture estimate "very similar to Motulsky's average estimate of 12.5%." This supported the finding that "Diaspora Jews from Europe, Northwest Africa, and the Near East resemble each other more closely than they resemble their non-Jewish neighbors."

A 2001 study by Nebel et al. showed that both Ashkenazi and Sephardic Jewish populations share the same overall paternal Near Eastern ancestries. In comparison with data available from other relevant populations in the region, Jews were found to be more closely related to groups in the north of the Fertile Crescent

The Fertile Crescent, nicknamed "The Cradle of Civilization" for the fact the first civilizations started there, is a crescent-shaped region containing the comparatively moist and fertile land of otherwise arid and semi-arid Western Asia. The term was first used by University of Chicago...

. The authors also report on Eu 19 (R1a) chromosomes, which are very frequent in Eastern Europeans (54%-60%) at elevated frequency (12.7%) in Ashkenazi Jews. They hypothesized that the differences among Ashkenazim Jews could reflect low-level gene flow from surrounding European populations and/or genetic drift during isolation. A later 2005 study by Nebel et al., found a similar level of 11.5% of male Ashkenazim belonging to R1a1a (M17+), the dominant Y-chromosome haplogroup in Eastern Europeans, suggesting possible gene flow.

Female lineages: Mitochondrial DNA

Before 2006, geneticists largely attributed the genesis of most of the world's Jewish populations

Jewish ethnic divisions

, including Ashkenazi Jews, to founding effects by males who migrated from the Middle East and "by the women from each local population whom they took as wives and converted to Judaism." In line with this model of origin, David Goldstein, now of Duke University, reported in 2002 that, unlike male lineages, the female lineages in Ashkenazi Jewish communities "did not seem to be Middle Eastern", and that each community had its own genetic pattern and even that "in some cases the mitochondrial DNA was closely related to that of the host community." In his view this suggested "that Jewish men had arrived from the Middle East, taken wives from the host population and converted them to Judaism, after which there was no further intermarriage with non-Jews."

However, a 2006 study by Behar et al., based on high-resolution analysis of haplogroup K

Haplogroup K (mtDNA)

In human mitochondrial genetics, Haplogroup K is a human mitochondrial DNA haplogroup, defined by HVR1 mutations 16224C and 16311C.-Origin:It is the most common subclade of haplogroup U8, and it has an estimated age of c. 12,000 years BP....

ine mtDNA pool" originating in the Middle East in the 1st and 2nd centuries CE. Although Haplogroup K is common throughout western Eurasia, "the observed global pattern of distribution renders very unlikely the possibility that the four aforementioned founder lineages entered the Ashkenazi mtDNA pool via gene flow from a European host population:

"..Both the extent and location of the maternal ancestral deme

from which the Ashkenazi Jewry arose remain obscure. Here, using complete sequences of the maternally inherited mitochondrial DNA (mtDNA), we show that close to one-half of Ashkenazi Jews, estimated at 8,000,000 people, can be traced back to only four women carrying distinct mtDNAs that are virtually absent in other populations, with the important exception of low frequencies among non-Ashkenazi Jews. We conclude that four founding mtDNAs, likely of Near Eastern ancestry, underwent major expansion(s) in Europe within the past millennium.."

In addition, Behar et al. have suggested that the rest of Ashkenazi mtDNA is originated from ~150 women, most of those likely of Middle Eastern origin. However, other studies by Behar indicate that this mtDNA is different from other Jewish populations found outside of Europe, leaving the possibility of a separate origin or even a European origin a distinct possibility.

, a genome-wide association study

Genome-wide association study

(GWA study, or GWAS) is an examination of all or most of the genes (the genome) of different individuals of a particular species to see how much the genes vary from individual to individual. These techniques were originally designed for epidemiological uses, to identify genetic associations with observable traits.

A 2006 study by Seldin et al. used over five thousand autosomal SNPs to demonstrate European genetic substructure. The results showed “a consistent and reproducible distinction between ‘northern’ and ‘southern’ European population groups”. Most northern, central, and eastern Europeans (Finns, Swedes, English, Irish, Germans, and Ukrainians) showed >90% in the ‘northern’ population group, while most individual participants with southern European ancestry (Italians, Greeks, Portuguese, Spaniards) showed >85% in the 'southern' group. Both Ashkenazi Jews as well as Sephardic Jews showed >85% membership in the “southern” group. Referring to the Jews clustering with southern Europeans, the authors state the results were "consistent with a later Mediterranean origin of these ethnic groups".

A 2007 study by Bauchet et al. found that Ashkenazi Jews were most closely clustered with Arabic North African populations when compared to Global population, and in the European structure analysis, they share similarities only with Greeks and Southern Italians, reflecting their east Mediterranean origins.

A 2010 study on Jewish ancestry by Atzmon-Ostrer et al. stated "Two major groups were identified by principal component, phylogenetic, and identity by descent (IBD) analysis: Middle Eastern Jews and European/Syrian Jews. The IBD segment sharing and the proximity of European Jews to each other and to southern European populations suggested similar origins for European Jewry and refuted large-scale genetic contributions of Central and Eastern European and Slavic populations to the formation of Ashkenazi Jewry.", as both groups - the Middle Eastern Jews and European/Syrian Jews shared common ancestors in the Middle East about 2500 years ago. The study examines genetic markers spread across the entire genome and shows that the Jewish groups (Ashkenazi and non Ashkenazi) share large swaths of DNA, indicating close relationships and that each of the Jewish groups in the study (Iranian, Iraqi, Syrian, Italian, Turkish, Greek and Ashkenazi) has its own genetic signature but is more closely related to the other Jewish groups than to their fellow non-Jewish countrymen. Atzmon's team found that the SNP markers in genetic segments of 3 million DNA letters or longer were 10 times more likely to be identical among Jews than non-Jews. Results of the analysis also tally with biblical accounts of the fate of the Jews. Using their DNA analysis, the authors traced the ancestors of all Jews to Persia and Babylon, areas that now form part of Iran and Iraq. The study also found that with respect to non-Jewish European groups, the population most closely related to Ashkenazi Jews are modern-day Italians. The study speculated that the genetic-similarity between Ashkenazi Jews and Italians may be due to inter-marriage and conversions in the time of the Roman Empire. It was also found that any two Ashkenazi Jewish participants in the study shared about as much DNA as fourth or fifth cousins.

and Palestinian Arabs populations to represent the reference to world Jewry ancestor genome. With this reference point, the linkage disequilibrium in the Ashkenazi Jewish population was interpreted as "matches signs of interbreeding or 'admixture' between Middle Eastern and European populations". In their press release, Bray stated: "We were surprised to find evidence that Ashkenazi Jews have higher heterozygosity than Europeans, contradicting the widely-held presumption that they have been a largely isolated group". Nevertheless, the authors indicated possible Achilles' heel for the study is that their calculations might "overestimated the level of admixture" in case that the true Jewish ancestor was genetically closer to Southern Europeans than Druze and Palestinian Arabs are and predicted that using the non Ashkenazi Jewish Diaspora populations as reference for the Jewish ancestor genome would "underestimate the level of admixture", as they assume the non Ashkenazi Jewish Diaspora has also "undergone the similar admixture".

Medical genetics

There are many references to Ashkenazi Jews in the literature of medical and population genetics. Indeed, much awareness of "Ashkenazi Jews" as an ethnic group or category stems from the large number of genetic studies of disease, including many that are well reported in the media, that have been conducted among Jews. Jewish populations have been studied more thoroughly than most other human populations, for a variety of reasons:

Geneticists are intrinsically interested in Jewish populations as a disproportionate percentage of genetics researchers are Jewish. Israel in particular has become an international center of such research.
Jewish populations, and particularly the large Ashkenazi Jewish population, are ideal for such research studies, because they exhibit a high degree of endogamy
Endogamy

, yet they are sizable.
Jewish populations are overwhelmingly urban, and are concentrated near biomedical centers where such research has been carried out. Such research is especially easy to carry out in Israel, where cradle-to-grave medical insurance is available, together with universal screening for genetic disease.
Jewish communities are comparatively well informed about genetics research, and have been supportive of community efforts to study and prevent genetic diseases.
Participation of Jewish scientists and support from the Jewish community alleviates ethical concerns that sometimes hinder such genetic studies in other ethnic groups.

The result is a form of ascertainment bias. This has sometimes created an impression that Jews are more susceptible to genetic disease than other populations. Healthcare professionals are often taught to consider those of Ashkenazi descent to be at increased risk for colon cancer.
