Jewish ethnic divisions
Jewish ethnic divisions refer to many distinctive communities within the world's Jewish population. Although "Jewish" is considered an ethnicity itself, there are distinct ethnic subdivisions among Jews, most of which are primarily the result of geographic branching from an originating Israelite population, mixing with local communities, and subsequent independent evolutions.
During the millennia of the Jewish diaspora, the communities would develop under the influence of their local environments; political, cultural, natural and demographic. Today, the 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, and 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 and Africa, 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 ancient Israel 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.Paul Johnson writes of this time: "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."
Jewish communities continued to exist in Palestine in relatively small numbers: during the early Byzantine 6th century there were 43 communities; during the Islamic period and the intervening Crusades there were 50 ; and during the early Ottoman 14th century there were 30. The majority of the Jewish population during the High Middle Ages lived in Iberia and in the region of Mesopotamia and Persia, the former known as the Sefardim and the latter known as the Mizrahim. A substantial population existed also in central Europe, the so-called Ashkenazim. Following the expulsion of Sephardim from Iberia during the 15th century, a mass migration into the Ottoman Empire swelled the size of many eastern communities including those in Palestine; the town of Safed reached 30,000 Jews by end of the 16th century. 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.
Diaspora
Following the failure of the second revolt against the Romans and the exile, Jewish communities could be found in nearly every notable center throughout the Roman Empire, 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, but how much the traces of Judaism within this group survived the collapse of the Khazar empire is a matter of scholarly debate. Arthur Koestler, in his book The Thirteenth Tribe, and more recently Shlomo Sand in his book The Invention of the Jewish People theorized that East-European Jews are more ethnically Khazar than they are Semitic. Genetic studies have not supported this theory.
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, Scandinavia, 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. 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 Americas would increase in the early 18th century with German-speaking Ashkenazi 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. After the Holocaust, which resulted in the murder of more than 6 million Jews living in Europe, North America became the place where the majority of Jews live.
Modern divisions
Historically, European Jews have been classified as belonging to two major groups: the Ashkenazim, or "Germanics", denoting their Central European base, and the Sephardim, or "Spaniards", denoting their Spanish and Portuguese base. A third historic term Mizrahim, or "Easterners" has been used to describe other non-European Jewish communities which have bases which are located further to the east, but its usage has changed both over time and relative to the location where it was used. One definition is the Jews who never left the Middle East, in contrast to the Sephardim who went west to Spain, Portugal, and North Africa. A similar three-part distinction in the Jewish community of 16th-century Venice is noted by Johnson as being "divided into three nations, the Penentines from Spain, the Levantines who were Turkish subjects, and the Natione Tedesca or Jews of German origin..." The far more recent meaning of the term, to include both Middle Eastern and North African Jews in a single term, developed within Zionism in the mid-1940s, when Jews from these countries were all combined in one category as the target of an immigration plan. According to some sources, the current sense of the term as the name of an ethnic group distinct from European-born Jews was invented at this time. The term constitutes a third major layer to some, and following the partition of Mandatory Palestine and Israeli independence, the Mizrahim's often-forced migration, led to their establishment of communities in the newly constructed Israel.The divisions between these major groups are rough and their boundaries are not solid. The Mizrahim for example, are a heterogeneous collection of Jewish communities which are often as unrelated to each other as they are to any of the earlier mentioned Jewish groups. In traditional religious usage and sometimes in modern usage, however, Mizrahim overlap with termed Sephardi due to factors including the similar styles of liturgy, despite independent evolutions from Sephardim proper. Thus, among such Mizrahim there are Iranian Jews, Iraqi Jews, Egyptian Jews, Sudanese Jews, Tunisian Jews, Algerian Jews, Moroccan Jews, Lebanese Jews, Libyan Jews, Syrian Jews, Bukharan Jews, Georgian Jews, Kurdish Jews, Afghan Jews, and Mountain Jews. Other Asian groups that evolved separately from Sephardim such as Indian Jews including the Malabar Yehuddim, Bene Israel, Bnei Menashe and Bene Ephraim, and Chinese Jews, most notably the Kaifeng Jews. Yemenite Jews from Yemen are sometimes included, although their style of liturgy is unique compared to other 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 in 1497 from the expulsion decreed in Portugal.
Distinct smaller Jewish groups include the Italian rite Jews ; the Romaniotes of Greece; various African Jews, including most numerously the Beta Israel of Ethiopia; as well as various other distinct but now extinct communities.
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%. Ashkenazim developed in Europe, but underwent massive emigration in search of better opportunities and during periods of civil strife and warfare. As a result of this, they 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, Mexico, Canada, Argentina, and Brazil, 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.
