Ashkenaz is also a Japhetic patriarch in the Table of Nations (Genesis 10). Thus, Ashkenazim or Ashkenazi Jews are literally "German Jews." Many Ashkenazi Jews later migrated, largely eastward, forming communities in non German-speaking areas, including Hungary, Poland, Lithuania, Russia, Eastern Europe, and elsewhere between the 10th and 19th centuries. With them, they took and diversified Yiddish, a Germanic Jewish language that had since medieval times been the lingua franca among Ashkenazi Jews. To a much lesser extent, the Judaeo-French language Zarphatic and the Slavic-based Knaanic (Judaeo-Czech) were also spoken. The Ashkenazi Jews developed a distinct culture and liturgy; influenced, to varying degrees, by interaction with surrounding peoples of Central and Eastern Europe.
This makes it especially difficult to define who is an Ashkenazi Jew, because they have been defined by different people using religious, cultural, or ethnic perspectives. Since the overwhelming majority of Ashkenazi Jews no longer live in Eastern Europe, the isolation that once favored a distinct religious tradition and culture has vanished. Furthermore, the word Ashkenazi is being used in non-traditional ways, especially in Israel. By conservative and orthodox philosophies, a person can only be considered a Jew if their mother was Jewish (meaning more specifically that they descend from a female down the matrilineal line who was assumed to be present at Mt. Sinai when the ten commandments were given or one of their female matrilineal ancestors underwent what is considered to be a valid conversion before the birth of her children), or they themselves have undergone conversion. 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.
By tradition, a Sephardic or Mizrahi woman who marries into an Orthodox or Haredi Ashkenazi Jewish family raises her children to be Ashkenazi Jews, and a gentile who converts to Judaism and takes on Ashkenazi religious practices becomes an Ashkenazi Jew.
For Ashkenazi Jews living in Eastern Europe, chopped liver and gefiltefish were archetypal Jewish foods. To contemporary Ashkenazi Jews living both in Israel and in the diaspora, Middle Eastern foods such as hummus and falafel, neither traditional to the historic Ashkenazi experience, have become central to their lives as Ashkenazi Jews in the current era. Hebrew has replaced Yiddish as the primary Jewish language for many Ashkenazi Jews, although many Hasidic and Hareidi groups continue to use Yiddish in daily life.
Although France expelled its original Jewish population in the Middle Ages, by the time of the French Revolution, there were two distinct Jewish populations. One consisted of Sephardic Jews, originally refugees from the Inquisition and concentrated in the southwest, while the other community was Ashkenazi, concentrated in Alsace, and speaking mainly Yiddish. The two communities were so separate and different that the National Assembly emancipated them separately in 1791. But after emancipation, a sense of a unified French Jewry emerged, especially when France was wracked by the Dreyfuss affair in the 1890s. In the 1920s and 1930s, Ashkenazi Jews arrived in large numbers as refugees from antisemitism, the Russian revolution, and the economic turmoil of the Great Depression. By the 1930s, Paris had a vibrant Yiddish culture, and many Jews were involved in radical political movements. After the Vichy years and the Holocaust, the French Jewish population was augmented once again, first by refugees from Eastern Europe, and later by immigrants and refugees from North Africa, many of them francophone. Then, in the 1990s, yet another Ashkenazi Jewish wave began to arrive from countries of the former Soviet Union 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. Wall, Irwin.

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 haplotypes) as well as for matrilineal markers (mitochondrial haplotypes).
Orthodox religious authorities actually encourage this, because of the danger that a Jewish donor could be a mamzer. Thus, the concept of Ashkenazi Jews as a distinct ethnic people, especially in ways that can be defined ancestrally and therefore traced genetically, has also blurred considerably.
Jews have lived in Germany, or "Ashkenaz", at least since the early 4th century . When they arrived in northern France and the Rhineland, the Ashkenazi Jews brought with them both Rabbinic Judaism and the Babylonian Talmudic culture that underlies it . Yiddish, once spoken by the vast majority of Ashkenazi Jewry, is a Jewish language which developed from the Middle High German vernacular, heavily influenced by Hebrew and Aramaic. (By comparison, the Greek or Latin influence on Yiddish was much less significant).
This suggested that the male ancestors of the Ashkenazi Jews could be traced mostly to the Middle East. The proportion of male genetic admixture 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.
The authors hypothesized that these chromosomes could reflect low-level gene flow from surrounding Eastern European populations, or, alternatively, that both the Ashkenazi Jews with Eu 19, and to a much greater extent Eastern European populations in general, might partly be descendants of Khazars.

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.
