Jewish diaspora no relation Kingdom of Israel
The Jewish diaspora (Hebrew: תְּפוּצָה, romanized: təfūṣā) or exile (Hebrew: גָּלוּת gālūṯ; Yiddish: golus) is the dispersion of Israelites or Jews out of their ancient ancestral homeland (the Land of Israel) and their subsequent settlement in other parts of the globe.In terms of the Hebrew Bible, the term "Exile" denotes the fate of the Israelites who were taken into exile from the Kingdom of Israel during the 8th century BCE, and the Judahites from the Kingdom of Judah who were taken into exile during the 6th century BCE. While in exile, the Judahites became known as "Jews" (יְהוּדִים, or Yehudim), "Mordecai the Jew" from the Book of Esther being the first biblical mention of the term.
The first exile was the Assyrian exile, the expulsion from the Kingdom of Israel (Samaria) begun by Tiglath-Pileser III of Assyria in 733 BCE. This process was completed by Sargon II with the destruction of the kingdom in 722 BCE, concluding a three-year siege of Samaria begun by Shalmaneser V. The next experience of exile was the Babylonian captivity, in which portions of the population of the Kingdom of Judah were deported in 597 BCE and again in 586 BCE by the Neo-Babylonian Empire under the rule of Nebuchadnezzar II.
A Jewish diaspora existed for several centuries before the fall of the Second Temple, and their dwelling in other countries for the most part  was not a result of compulsory dislocation. Before the middle of the first century CE, in addition to Judea, Syria and Babylonia, large Jewish communities existed in the Roman provinces of Egypt, Crete and Cyrenaica, and in Rome itself; after the Siege of Jerusalem in 63 BCE, when the Hasmonean kingdom became a protectorate of Rome, emigration intensified. In 6 CE the region was organized as the Roman province of Judea. The Judean population revolted against the Roman Empire in 66 CE in the First Jewish–Roman War which culminated in the destruction of Jerusalem in 70 CE. During the siege, the Romans destroyed the Second Temple and most of Jerusalem. This watershed moment, the elimination of the symbolic centre of Judaism and Jewish identity motivated many Jews to formulate a new self-definition and adjust their existence to the prospect of an indefinite period of displacement.In 132 CE, Bar Kokhba led a rebellion against Hadrian, a revolt connected with the renaming of Jerusalem as Aelia Capitolina. After four years of devastating warfare, the uprising was suppressed, and Jews were forbidden access to Jerusalem.
During the Middle Ages, due to increasing migration and resettlement, Jews divided into distinct regional groups which today are generally addressed according to two primary geographical groupings: the Ashkenazi of Northern and Eastern Europe, and the Sephardic Jews of Iberia (Spain and Portugal), North Africa and the Middle East. These groups have parallel histories sharing many cultural similarities as well as a series of massacres, persecutions and expulsions, such as the expulsion from England in 1290, the expulsion from Spain in 1492, and the expulsion from Arab countries in 1948–1973. Although the two branches comprise many unique ethno-cultural practices and have links to their local host populations (such as Central Europeans for the Ashkenazim and Hispanics and Arabs for the Sephardim), their shared religion and ancestry, as well as their continuous communication and population transfers, has been responsible for a unified sense of cultural and religious Jewish identity between Sephardim and Ashkenazim from the late Roman period to the present.Middle Ages
Ashkenazi Jews
Ashkenazi Jews is a general category of Jewish populations who immigrated to what is now Germany and northeastern France during the Middle Ages and until modern times used to adhere to the Yiddish culture and the Ashkenazi prayer style. There is evidence that groups of Jews had immigrated to Germania during the Roman Era; they were probably merchants who followed the Roman Legions during their conquests. However, for the most part, modern Ashkenazi Jews originated with Jews who migrated or were forcibly taken from the Middle East to southern Europe in antiquity, where they established Jewish communities before moving into northern France and lower Germany during the High and Late Middle Ages. They also descend to a lesser degree from Jewish immigrants from Babylon, Persia, and North Africa who migrated to Europe in the Middle Ages. The Ashkenazi Jews later migrated from Germany (and elsewhere in Central Europe) into Eastern Europe as a result of persecution. Some Ashkenazi Jews also have minor ancestry from Sephardi Jews exiled from Spain, first during Islamic persecutions (11th-12th centuries) and later during Christian reconquests (13th-15th centuries) and the Spanish Inquisition (15th-16th centuries). Ashkenazi Jews are of mixed Middle Eastern and European ancestry, as they derive part of their ancestry from non-Jewish Europeans who intermixed with Jews of migrant Middle Eastern origin.
In 2006, a study by Doron Behar and Karl Skorecki of the Technion and Ramban Medical Center in Haifa, Israel demonstrated that the vast majority of Ashkenazi Jews, both men and women, have Middle Eastern ancestry. According to Nicholas Wades' 2010 Autosomal study Ashkenazi Jews share a common ancestry with other Jewish groups and Ashkenazi and Sephardi Jews have roughly 30% European ancestry with the rest being Middle Eastern. According to Hammer, the Ashkenazi population expanded through a series of bottlenecks—events that squeeze a population down to small numbers—perhaps as it migrated from the Middle East after the destruction of the Second Temple in 70 CE, to Italy, reaching the Rhine Valley in the 10th century.
David Goldstein, a Duke University geneticist and director of the Duke Center for Human Genome Variation, has said that the work of the Technion and Ramban team served only to confirm that genetic drift played a major role in shaping Ashkenazi mitochondrial DNA (mtDNA), which is inherited in a matrilineal manner. Goldstein argues that the Technion and Ramban mtDNA studies fail to actually establish a statistically significant maternal link between modern Jews and historic Middle Eastern populations. This differs from the patrilineal case, where Goldstein said there is no doubt of a Middle Eastern origin.In June 2010, Behar et al. "shows that most Jewish samples form a remarkably tight subcluster with common genetic origin, that overlies Druze and Cypriot samples but not samples from other Levantine populations or paired diaspora host populations. In contrast, Ethiopian Jews (Beta Israel) and Indian Jews (Bene Israel and Cochini) cluster with neighboring autochthonous populations in Ethiopia and western India, respectively, despite a clear paternal link between the Bene Israel and the Levant.". "The most parsimonious explanation for these observations is a common genetic origin, which is consistent with an historical formulation of the Jewish people as descending from ancient Hebrew and Israelite residents of the Levant." In conclusion the authors are stating that the genetic results are concordant "with the dispersion of the people of ancient Israel throughout the Old World". Regarding the samples he used Behar points out that "Our conclusion favoring common ancestry (of Jewish people) over recent admixture is further supported by the fact that our sample contains individuals that are known not to be admixed in the most recent one or two generations."
A 2013 study of Ashkenazi mitochondrial DNA by Costa et al., reached the conclusion that the four major female founders and most of the minor female founders had ancestry in prehistoric Europe, rather than the Near East or Caucasus. According to the study these findings 'point to a significant role for the conversion of women in the formation of Ashkenazi communities" and their intermarriage with Jewish men of Middle Eastern origin.A study by Haber, et al., (2013) noted that while previous studies of the Levant, which had focused mainly on diaspora Jewish populations, showed that the "Jews form a distinctive cluster in the Middle East", these studies did not make clear "whether the factors driving this structure would also involve other groups in the Levant". The authors found strong evidence that modern Levant populations descend from two major apparent ancestral populations. One set of genetic characteristics which is shared with modern-day Europeans and Central Asians is most prominent in the Levant amongst "Lebanese, Armenians, Cypriots, Druze and Jews, as well as Turks, Iranians and Caucasian populations". The second set of inherited genetic characteristics is shared with populations in other parts of the Middle East as well as some African populations. Levant populations in this category today include "Palestinians, Jordanians, Syrians, as well as North Africans, Ethiopians, Saudis, and Bedouins". Concerning this second component of ancestry, the authors remark that while it correlates with "the pattern of the Islamic expansion", and that "a pre-Islamic expansion Levant was more genetically similar to Europeans than to Middle Easterners," they also say that "its presence in Lebanese Christians, Sephardi and Ashkenazi Jews, Cypriots and Armenians might suggest that its spread to the Levant could also represent an earlier event". The authors also found a strong correlation between religion and apparent ancestry in the Levant:
