Jews are the Jews of medieval Ashkenaz—the Rhineland and northern France—who migrated eastward into Poland-Lithuania, developing and a distinctive rabbinic culture.1 By the 19th century they lived largely in the Russian Pale of Settlement and formed the demographic majority of world Jewry until the Holocaust.2

Origins

"Ashkenaz" was the medieval Hebrew name for Germany, and the term "" came to denote the Jews of Germany, northern France, and their descendants.1 Their first compact area of settlement lay on the banks of the Rhine—the ShUM cities of Speyer, Worms, and Mainz—where a distinctive Jewish culture had formed by the 10th century.1 Rashi and the Tosafists made nearby Champagne a center of Talmudic learning.3 Persecution during the First Crusade of 10964 and, above all, the Black Death massacres of 1348–1349 drove a large migration eastward into Poland and Lithuania, which became the community's demographic heartland.5

Religious life

Around 1000 CE, Rabbeinu Gershom of Mainz convened a council whose takkanot—prohibiting polygamy and forbidding divorce without a wife's consent—became binding across Ashkenaz.6 Rashi's comprehensive commentaries on the Talmud and Hebrew Bible, elaborated by the Tosafists, made Talmud study the core of learning.7 Distinct Ashkenazi custom (minhag) was recorded in Moses Isserles' Mapah, his glosses on Joseph Karo's Shulchan Arukh, embedded in every printed edition since 1578.8 In the 18th century Ashkenazi Jewry split between the Hasidic movement founded by the Baal Shem Tov9 and its Mitnagdic opponents, led by the Vilna Gaon.10

Language & culture

The vernacular was , based on High German and fused with elements of Hebrew, Aramaic, Romance, and Slavic languages, and written in the Hebrew alphabet.11 It emerged in the Rhineland by about the 10th century and later shifted its center to Eastern Europe.1 Before World War II Yiddish still counted 11–13 million speakers, overwhelmingly Ashkenazi Jews.12 Alongside its religious writings, Yiddish carried a rich secular literature from the 19th century, exemplified by the author Sholem Aleichem.13

Relations with neighbours

In the medieval West, status was precarious: communities depended on the protection of bishops and kings and suffered massacres in 1096,4 expulsion from England in 1290,14 and the Black Death .5 In Poland-Lithuania, by contrast, rulers issued protective charters: the Statute of Kalisz of 1264, granted by Bolesław the Pious and later confirmed by Casimir the Great, gave Jews legal autonomy and their own courts.15 Communal self-government reached its height in the Council of Four Lands, the central body of Jewish autonomy in Poland from the late 16th century until 1764.16

Decline & dispersal

The Khmelnytsky uprising of 1648 unleashed Cossack that killed thousands of Jews across Ukraine and Poland.17 The partitions of Poland placed most under Russian rule, confined after 1791 to the Pale of Settlement, which at its height held over five million Jews.2 Pogroms from 1881 and the repressive May Laws of 1882 drove some two million Jews to emigrate, chiefly to the United States, between 1880 and 1920.18 Finally, the Holocaust of 1941–1945 murdered about six million Jews19—some 85% of them speakers—destroying the Eastern European heartland of Ashkenazi life.12

Notable figures

  • Rabbeinu Gershom (Gershom ben Judah) (9601028)Early Ashkenazi Talmudic authority. Sage of Mainz called "Me'or ha-Golah"; around 1000 CE his takkanot banned polygamy and barred divorcing a wife without her consent.6
  • Rashi (Shlomo Yitzchaki) (10401105)Talmudic and biblical commentator. Rabbi of Troyes in northern France whose commentaries on the Talmud and Hebrew Bible became foundational for all later study.7
  • Baal Shem Tov (Israel ben Eliezer) (16981760)Founder of Hasidic Judaism. Podolian mystic and healer regarded as the founder of Hasidism, the movement that reshaped popular religious life across Eastern Europe.9
  • Vilna Gaon (Elijah ben Solomon Zalman) (17201797)Talmudist and leader of the Mitnagdim. Preeminent Lithuanian Talmudist and kabbalist of Vilna, foremost leader of the Mitnagdim who resisted the spread of Hasidism.10
  • Sholem Aleichem (Solomon Rabinovich) (18591916)Yiddish author and playwright. Leading author of the Russian Empire; his Tevye stories later inspired the musical Fiddler on the Roof.13

Key events

  • 1096 Rhineland massacres. During the First Crusade, mobs led by Count Emicho destroyed the Jewish communities of Speyer, Worms, and Mainz—the ShUM cities—killing roughly 2,000 Jews.4
  • 1264 Statute of Kalisz. Bolesław the Pious granted Poland's Jews a general charter of protection and legal autonomy, giving Jewish courts jurisdiction over Jewish affairs.15
  • 1290 Expulsion of Jews from England. Edward I's Edict of Expulsion banished all Jews from England; they were not readmitted until 1656, under Oliver Cromwell.14
  • 1349 Black Death massacres. Falsely accused of poisoning wells, Rhineland Jewish communities were massacred—about 2,000 burned at Strasbourg in 1349—accelerating migration eastward to Poland.5
  • 1648 Khmelnytsky massacres. Cossacks under Bohdan Khmelnytsky slaughtered Jewish communities across Ukraine; modern estimates of the 1648 dead range from several thousand to about 20,000.17
  • 1791 Creation of the Pale of Settlement. Catherine the Great confined Jewish residence to a western Pale carved from the Polish partitions; at its height it held over five million Jews.2
  • 1881 Pogroms and mass emigration. After Alexander II's assassination, anti-Jewish riots swept the Russian Empire and the 1882 May Laws followed; some two million Jews emigrated by 1920.18
  • 1941 The Holocaust. From 1941 to 1945 Nazi Germany and its collaborators murdered about six million Jews—two-thirds of European Jewry—annihilating communities across Eastern Europe.19

Genetic evidence

  • autosomalGenome-wide data place most Jewish populations, including , in a tight cluster overlying Druze and Cypriot samples, tracing their origins to the Levant.20 (supports)
  • mtDNAAbout 40% of traces to four founders of prehistoric European ancestry,21 and the great majority of Ashkenazi maternal lineages appear to have been assimilated within Europe rather than brought from the Levant.21 (complicates)
  • autosomal and identity-by-descent analysis shows the cluster shares Middle Eastern ancestry while carrying substantial European and some North African .22 (supports)
  • autosomalWhole-genome sequencing indicates modern Jews passed through a severe recent bottleneck of only a few hundred individuals23 and descend in nearly equal measure from European and Middle Eastern ancestral populations.23 (complicates)
