paragraph_text: Immigration to Israel during the late 1940s and early 1950s was aided by the Israeli Immigration Department and the non-government sponsored Mossad LeAliyah Bet ("Institution for Illegal Immigration"). Both groups facilitated regular immigration logistics like arranging transportation, but the latter also engaged in clandestine operations in countries, particularly in the Middle East and Eastern Europe, where the lives of Jews were believed to be in danger and exit from those places was difficult. Mossad LeAliyah Bet continued to take part in immigration efforts until its disbanding in 1953. An influx of Holocaust survivors and Jews from Arab and Muslim lands immigrated to Israel during the first 3 years and the number of Jews increased from 700,000 to 1,400,000, many of whom faced persecution in their original countries. The immigration was in accordance with the One Million Plan.

paragraph_text: In an ethnic sense, an Ashkenazi Jew is one whose ancestry can be traced to the Jews who settled in Central 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 argued that genetic variations have been identified that show high frequencies among Ashkenazi Jews, but not in the general European population, be they for patrilineal markers (Y-chromosome haplotypes) and for matrilineal markers (mitotypes). However, a 2013 study of Ashkenazi mitochondrial DNA, from the University of Huddersfield in England, suggests that at least 80 percent of the Ashkenazi maternal lineages derive from the assimilation of mtDNAs indigenous to Europe, probably as a consequence of conversion. 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.

paragraph_text: Jews in New York City comprise approximately 13 percent of the city's population, making the Jewish community the largest in the world outside of Israel. As of 2014, 1.1 million Jews live in the five boroughs of New York City, and 1.75 million Jews live in New York state overall. Jews have immigrated to New York City since the first settlement in Dutch New Amsterdam in 1654, most notably at the end of the 19th century to the early 20th century, when the Jewish population rose from about 80,000 in 1880 to 1.5 million in 1920. The large Jewish population has led to a significant impact on the culture of New York City. After many decades of decline in the 20th century, the Jewish population of New York City has seen a sharp increase in the 21st century owing to the high birth rate of the Hasidic and Orthodox communities.

paragraph_text: Sporadic use of the term for some of the subject matter occurred subsequently, such as the use by Étienne Serres in 1838 to describe the natural history, or paleontology, of man, based on comparative anatomy, and the creation of a chair in anthropology and ethnography in 1850 at the National Museum of Natural History (France) by Jean Louis Armand de Quatrefages de Bréau. Various short-lived organizations of anthropologists had already been formed. The Société Ethnologique de Paris, the first to use Ethnology, was formed in 1839. Its members were primarily anti-slavery activists. When slavery was abolished in France in 1848 the Société was abandoned.

paragraph_text: Telman Mardanovich Ismailov (, ; born 26 October 1956) is an Azerbaijani-born businessman and entrepreneur of Mountain Jew origin. Since Azerbaijan does not allow dual citizenship, he holds Russian-Turkish citizenship. He is the chairman of the Russian AST Group of companies, which is active in many countries. Until 2009, Ismailov owned the Europe's then-largest marketplace, Cherkizovsky Market, located in Moscow, Russia.

paragraph_text: Orthodox Judaism outreach commonly referred to as Kiruv or Keruv, is the movement of Orthodox Judaism that reaches out to non-Orthodox Jews to practice the Mitzvot in the hope that they will live according to Orthodox Jewish law.

paragraph_text: Since the existence of the earliest Jewish diaspora, many Jews have aspired to return to "Zion" and the "Land of Israel", though the amount of effort that should be spent towards such an aim was a matter of dispute. The hopes and yearnings of Jews living in exile are an important theme of the Jewish belief system. After the Jews were expelled from Spain in 1492, some communities settled in Palestine. During the 16th century, Jewish communities struck roots in the Four Holy Cities—Jerusalem, Tiberias, Hebron, and Safed—and in 1697, Rabbi Yehuda Hachasid led a group of 1,500 Jews to Jerusalem. In the second half of the 18th century, Eastern European opponents of Hasidism, known as the Perushim, settled in Palestine.

paragraph_text: Culturally, an Ashkenazi Jew can be identified by the concept of Yiddishkeit, which means "Jewishness" in the Yiddish language. Yiddishkeit is specifically the Jewishness of Ashkenazi Jews. Before the Haskalah and the emancipation of Jews in Europe, this meant the study of Torah and Talmud for men, and a family and communal life governed by the observance of Jewish Law for men and women. From the Rhineland to Riga to Romania, 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. Broadly speaking, a Jew is one who associates culturally with Jews, supports Jewish institutions, reads Jewish books and periodicals, attends Jewish movies and theater, travels to Israel, visits historical synagogues, and so forth. It is a definition that applies to Jewish culture in general, and to Ashkenazi Yiddishkeit in particular.

paragraph_text: Allan Kardec () is the pen name of the French educator, translator and author Hippolyte Léon Denizard Rivail (; 3 October 1804 – 31 March 1869). He is the author of the five books known as the Spiritist Codification, and is the founder of Spiritism.

paragraph_text: The origins of the Ashkenazim are obscure, and many theories have arisen speculating about their ultimate provenance. The most well supported theory is the one that details a Jewish migration through what is now Italy and other parts of southern Europe. The historical record attests to Jewish communities in southern Europe since pre-Christian times. Many Jews were denied full Roman citizenship until 212 CE, when Emperor Caracalla granted all free peoples this privilege. Jews were required to pay a poll tax until the reign of Emperor Julian in 363. In the late Roman Empire, Jews were free to form networks of cultural and religious ties and enter into various local occupations. But, after Christianity became the official religion of Rome and Constantinople in 380, Jews were increasingly marginalized.

paragraph_text: Western Europe's largest Jewish community, and the third-largest Jewish community in the world, can be found in France, home to between 483,000 and 500,000 Jews, the majority of whom are immigrants or refugees from North African Arab countries such as Algeria, Morocco, and Tunisia (or their descendants). The United Kingdom has a Jewish community of 292,000. In Eastern Europe, there are anywhere from 350,000 to one million Jews living in the former Soviet Union, but exact figures are difficult to establish. In Germany, the 102,000 Jews registered with the Jewish community are a slowly declining population, despite the immigration of tens of thousands of Jews from the former Soviet Union since the fall of the Berlin Wall. Thousands of Israelis also live in Germany, either permanently or temporarily, for economic reasons.

paragraph_text: Graenum Berger (1908–1999) was an American Communal administrator, institutional and communal planner, educator, world traveler, and the founding President of the American Association for Ethiopian Jews.

paragraph_text: Prior to 1948, approximately 800,000 Jews were living in lands which now make up the Arab world (excluding Israel). Of these, just under two-thirds lived in the French-controlled Maghreb region, 15–20% in the Kingdom of Iraq, approximately 10% in the Kingdom of Egypt and approximately 7% in the Kingdom of Yemen. A further 200,000 lived in Pahlavi Iran and the Republic of Turkey. Today, around 26,000 Jews live in Arab countries and around 30,000 in Iran and Turkey. A small-scale exodus had begun in many countries in the early decades of the 20th century, although the only substantial aliyah came from Yemen and Syria. The exodus from Arab and Muslim countries took place primarily from 1948. The first large-scale exoduses took place in the late 1940s and early 1950s, primarily in Iraq, Yemen and Libya, with up to 90% of these communities leaving within a few years. The peak of the exodus from Egypt occurred in 1956. The exodus in the Maghreb countries peaked in the 1960s. Lebanon was the only Arab country to see a temporary increase in its Jewish population during this period, due to an influx of refugees from other Arab countries, although by the mid-1970s the Jewish community of Lebanon had also dwindled. In the aftermath of the exodus wave from Arab states, an additional migration of Iranian Jews peaked in the 1980s when around 80% of Iranian Jews left the country.[citation needed]

paragraph_text: More than half of the Jews live in the Diaspora (see Population table). Currently, the largest Jewish community outside Israel, and either the largest or second-largest Jewish community in the world, is located in the United States, with 5.2 million to 6.4 million Jews by various estimates. Elsewhere in the Americas, there are also large Jewish populations in Canada (315,000), Argentina (180,000-300,000), and Brazil (196,000-600,000), and smaller populations in Mexico, Uruguay, Venezuela, Chile, Colombia and several other countries (see History of the Jews in Latin America). Demographers disagree on whether the United States has a larger Jewish population than Israel, with many maintaining that Israel surpassed the United States in Jewish population during the 2000s, while others maintain that the United States still has the largest Jewish population in the world. Currently, a major national Jewish population survey is planned to ascertain whether or not Israel has overtaken the United States in Jewish population.

paragraph_text: According to 16th-century mystic Rabbi Elijah of Chelm, Ashkenazi Jews lived in Jerusalem during the 11th century. The story is told that a German-speaking Palestinian Jew saved the life of a young German man surnamed Dolberger. So when the knights of the First Crusade came to siege Jerusalem, one of Dolberger's family members who was among them rescued Jews in Palestine and carried them back to Worms to repay the favor. Further evidence of German communities in the holy city comes in the form of halakhic questions sent from Germany to Jerusalem during the second half of the 11th century.

paragraph_text: The Bronx underwent rapid urban growth after World War I. Extensions of the New York City Subway contributed to the increase in population as thousands of immigrants came to the Bronx, resulting in a major boom in residential construction. Among these groups, many Irish Americans, Italian Americans and especially Jewish Americans settled here. In addition, French, German, Polish and other immigrants moved into the borough. The Jewish population also increased notably during this time. In 1937, according to Jewish organizations, 592,185 Jews lived in The Bronx (43.9% of the borough's population), while only 54,000 Jews lived in the borough in 2011. Many synagogues still stand in the Bronx, but most have been converted to other uses.

paragraph_text: In 2016, Israel's population was an estimated 8,476,600 million people, of whom 6,345,400 (74.9%) were recorded by the civil government as Jews. 1,760,400 Arabs comprised 20.7% of the population, while non-Arab Christians and people who have no religion listed in the civil registry made up 4.4%. Over the last decade, large numbers of migrant workers from Romania, Thailand, China, Africa, and South America have settled in Israel. Exact figures are unknown, as many of them are living in the country illegally, but estimates run in the region of 203,000. By June 2012, approximately 60,000 African migrants had entered Israel. About 92% of Israelis live in urban areas.

paragraph_text: Camille Pelletan was educated in Paris, passed as licentiate in laws, and studied at the "École Nationale des Chartes" where he was qualified as an "archiviste paléographe". At the age of twenty he became an active journalist, and a bitter critic of the Imperial Government. After the war of 1870-71 he took a leading place among the Radicals, as an opponent of the "Opportunist Republicans" who continued the policy of Léon Gambetta.

paragraph_text: He studied science at the Muséum national d'histoire naturelle in Paris, where he was influenced by scientists that included biologist Jean Louis Armand de Quatrefages de Bréau, zoologist Alphonse Milne-Edwards, and anthropologist Ernest Hamy. From 1889 to 1892, he was employed as a chemical engineer at the French-owned El Boleo mining installation in Santa Rosalia, Baja California Sur. During that period, he explored the peninsula's interior, collecting natural history specimens for the National Museum of Natural History in Paris. Afterwards, from 1893 to 1914, he made six more trips to Mexico as an explorer and collector:

paragraph_text: David Rabeeya is an Iraqi Jew born in Baghdad, Iraq. He and his family later moved to Israel in about 1951. In about 1970, he moved to the United States. Over the years, Dr. Rabeeya has taught countless students, in all schooling environments-high school, university, and elementary school. He has grown to accept all different cultures and religions over his lifetime, as an Arab Jew. A prolific author, Dr. Rabeeya has written many books on many subjects, but they tend to focus on the Middle East and the relationship between Jews and other groups. He currently works as a teacher for Middle and High School students.
