The two major branches

Despite the fundamental uniformity of medieval Jewish culture, distinctive Jewish subcultures were shaped by the cultural and political divisions within the Mediterranean basin, in which Arabic Muslim and Latin Christian civilizations coexisted as discrete and self-contained societies. Two major branches of rabbinic civilization developed in Europe: the Ashkenazic, or Franco-German, and the Sephardic, or Andalusian-Spanish. Distinguished most conspicuously by their varying pronunciation of Hebrew, the numerous differences between them in religious orientation and practice derived, in the first instance, from the geographical fountainheads of their culture—the Ashkenazim (plural of Ashkenazi) tracing their cultural filiation to Italy and Palestine and the Sephardim (plural of Sephardi) to Babylonia—and from the influences of their respective immediate milieus. While the Jews of Christian Europe wrote for internal use almost exclusively in Hebrew, those of Muslim areas regularly employed Arabic for prose works and Hebrew for poetic composition. Whereas the literature of Jews in Latin areas was overwhelmingly religious in content, that of the Jews of Spain was well endowed with secular poetry and scientific works inspired by the cultural tastes of the Arabic literati. Most significantly, the two forms of European Judaism differed in their approaches to the identical rabbinic base that they had inherited from the East and in their attitudes to Gentile culture and politics.

Sephardic developments

In Muslim Spain, Jews frequently served the government in official capacities and, therefore, not only took an active interest in political affairs but engaged in considerable social and intellectual intercourse with influential circles of the Muslim population. Since the support of letters and scholarship was part of state policy in Muslim Spain, and since Muslim savants traced the source of Muslim power to the vitality of the Arabic language, scripture, and poetry, Jews looked at Arabic culture with undisguised admiration and unabashedly attempted to adapt themselves to its canons of scholarship and good taste. The cultured Jew accordingly demonstrated command of Arabic style and the ability to display the beauty of his own heritage through a philological mastery of the text of the Hebrew Bible and through the composition of Hebrew verse, now set to an Arabic metre. Since Arabic philosophers and scientists promulgated the compatibility of Greek philosophy with the revelation to Muhammad, rationalist study of the Jewish classics and defense of rabbinic faith in philosophical terms became dominant motifs in the Andalusian Jewish schools (in southern Spain).

The period of feverish literary creativity in classical Jewish disciplines as well as in the sciences in Spain has been called the golden age of Hebrew literature (c. 1000–1148). Jewish culture of this age was distinguished by the supreme literary merit of its Hebrew poetry, the new spirit of relatively free and rationalist examination of hallowed texts and doctrines, and the extension of Jewish cultural perspectives to totally new horizons—mathematics, astronomy, medicine, philosophy, political theory, aesthetics, and belles-lettres. Noteworthy too was the frequent overlapping of the Sephardic religious leadership with the new Jewish courtier class. The unprecedented heights that the latter attained—Ḥisdai ibn Shaprut (c. 915–975) as counsellor to the caliphs of Córdoba; the Ibn Nagrelas as viziers of Granada; the Ibn Ezras (Moses ibn Ezra, c. 1060–1139; and Abraham ben Meir ibn Ezra, c. 1092–1167), the Ibn Megashs, and the Ibn Albalias as high officials in Granada and Sevilla (Seville)—and the distinctions of these men and their protégés in Jewish and worldly letters restored the ancient integration of culture and practical life and expressed the identification of the Jewish elite with the biblical age of Jewish power and artistic creativity. The effort to recapture the vitality and beauty of biblical poetry stimulated comparative philological and fresh exegetical research that yielded new insights into the morphology of the Hebrew language and into the historical soil of biblical prophecy. Judah ibn Ḥayyuj and Abū al-Walīd Marwān ibn Janāḥ produced manuals on biblical grammar that applied the results of Arabic philology to their own tongue and provided the principles of Hebrew grammatical study down to modern times. The anticipations of modern higher biblical criticism by Judah ibn Balaʿam and Moses ibn Gikatilla (11th century) were popularized in Hebrew a few generations later by Abraham ibn Ezra. In the revival of Hebrew poetry, liturgical as well as secular, that translated the new preoccupation with language and beauty into art, Andalusian Jewry saw its greatest achievements. Solomon ibn Gabirol (c. 1022–c. 1058), Moses ibn Ezra, and Judah ha-Levi (c. 1075–1141) were the acknowledged supreme geniuses of a form of expression that became a passion with thousands the length and breadth of Spain. But the most enduring consequence of the new temper was the redefinition of religious faith in the light of Greco-Arabic philosophical theories. The exposition of faith in Neoplatonic terms by Solomon ibn Gabirol, the defense of Rabbinism using Aristotelian categories by Abraham ibn Daud (c. 1110–c. 1180), the attack on the religious inadequacy of philosophy by Judah ha-Levi, and the epoch-making Aristotelian philosophical theology by Moses Maimonides (1135–1204) fixed philosophical inquiry as an enduring subject on the agenda of rabbinic concerns. Beginning in the 13th century, a new class of philosophers sponsored the translation of Arabic literature into Hebrew and of Hebrew and Arabic literature into Latin; they brought Jews and their thought into the mainstream of Western philosophy and gained for them the position of middlemen of culture between East and West.

The salient trends of Sephardic Judaism did not imply relegation of the rabbinic class to a secondary role. Rather, they shaped a fresh approach to rabbinic texts that paralleled in many respects those adopted in biblical exegesis. Strict adherence to consistency, systematization, and philological exactitude yielded new codes that often diverged from gaonic judgments. A digest of Talmudic law by Isaac Alfasi (1013–1103) placed the Sephardic rabbinate on a self-reliant footing and epitomized its method of getting at the essentials of Talmudic law by sidestepping contingent discussions. In this area too, it was Moses Maimonides who brought the Sephardic principles of comprehensiveness, lucidity, and logical arrangement to their apex through his code of Jewish law, Mishne Torah. Written in Mishnaic Hebrew, the work remains the only comprehensive treatment of all of Jewish law, including those fields that are not applicable in the Diaspora (agriculture, purity, sacrifices, Temple procedure).

With Maimonides, however, the pure Sephardic tradition came to an end, for the Almohad (Amazigh [Berber] Muslim reformers) invasion of Spain in 1147–48 wiped out the Jewish communities of Andalusia and drove thousands to northern Spain and Provence (a province of southeastern France) or, as in the case of Maimonides’ family, to North Africa and Egypt. Sephardic Jewry suddenly encountered a discrete, mature, Jewish culture that for centuries had been developing independently and along quite different lines.

Ashkenazic developments

The Ashkenazic Jewry, into whose communities the Sephardim had been thrust by political events, regarded their own heritage and the Christian world in which they lived from a perspective shaped exclusively by rabbinic categories. They drew their school texts and the values that determined their judgments from the Talmud and the Midrash. Sensing no intellectual challenge in Christian faith, which they regarded with thinly concealed contempt, they constituted for the most part a merchant class that lived in urban centres under the protection of ecclesiastical and temporal rulers but also under their own complex of laws and institutions. Except for mercantile relations, Christian society was closed to them, thanks largely to age-old ecclesiastical prohibitions forbidding all social intercourse with Jews. With the Arab conquest of Spain and the rise of the Carolingians (the dynasty that ruled western Europe in the 8th and 9th centuries), the 12-decade interlude of suppression by the Visigoths (589–711) came to an end, and the Roman precedent of toleration and autonomy again became the rule. Merchants and rabbis moved from Italy to France and the Rhineland and infused new energies into the Jewish communities there. An indigenous religious leadership began to emerge at the very time that Andalusian Jewry was entering its golden age. The First Crusade (1096–99) unleashed a tide of hatred, periodic violence, and progressive restrictions on Jewish activities in the Rhineland, but the communities affected had attained sufficient resilience to reestablish their communal institutions shortly afterward and to continue the cultivation of their deeply ingrained traditions.

By 1150 Ashkenazic Jewry had established a culture of its own, with an indigenous literature that ranged from the popular homily to the esoteric tract on the nature of the divine glory. Study of the Bible and the Talmud was oriented toward a mystical pietism in which prayer and contemplation of the secrets embedded in the liturgy were to lead to religious experience. Significantly, the fathers of the Ashkenazic tradition were remembered as liturgical poets and initiates into divine mysteries, and the early codes of the Franco-German schools were heavily weighted with discussions of liturgical usage. After the Second Crusade (1147–49), the German Jewish mystics (also called Hasidim, or pietists) placed heavy emphasis on the merits of asceticism, martyrdom, and penitence, thus adapting to a Jewish idiom the features of saintliness then current in Christian Europe. For the masses of Jews, the cultural fare consisted principally of biblical tales and instruction as interpreted by rabbinic Midrash, the lives of scholars and saints, and liturgical poetry reaffirming the election of Israel and faith in messianic redemption. The chief vehicle of popular instruction consisted of anthologies from the rabbinic writings and commentaries on Scripture, of which the most popular was that of Rabbi Solomon ben Isaac of Troyes (1040–1105), known as Rashi, the acronym formed from the initials of his name in Hebrew. For the more advanced student, Rashi composed a succinct commentary on the Talmud that achieved an authority approaching that of the text itself.

As living sources of law and values, the Bible and the Talmud had an impact on public and private, as well as secular and religious, affairs. Taking their cue from Talmudic precedent and from Christian ecclesiastical procedures of their own times, the Ashkenazic rabbis occasionally gathered in regional synods to enact legislation on problems of a general nature for which there was no adequate precedent in the literature. Among the most enduring of these measures were the prohibition of bigamy and arbitrary divorce and severe economic penalties for abandonment of wives. Of far more immediate concern to the average Jew were the circumvention of Talmudic prohibitions against usury, relaxation of prohibitions regarding traffic with Gentiles in wines, and adoption of severe disciplinary measures, such as excommunication, against informers or those appealing, in cases involving Jews, to the Gentile authorities.

A new religious trend began in Provence in the 13th century with the introduction into the Talmudic academies of a novel form of mystical study known as Kabbala (literally, “tradition”), which soon spread to northern Spain. Expressing gnostic doctrines in rabbinic guise, the devotees of Kabbala devised an esoteric vocabulary that reinterpreted the Bible and rabbinic law as allegories of the various modes in which God is manifested in a spiritual universe, access to which was reserved for initiates. The most renowned literary product of this new circle was the Zohar (“The Book of Splendour”), a vast mystical commentary on the Pentateuch by Moses de León (c. 1250–1305); with later additions it became the Bible of Jewish mystics everywhere. Although some of the theological notions of the Kabbalists deviated from basic postulates of Jewish monotheism, the insistence of the mystics on unflagging ritual orthodoxy and on a nominal acceptance of the biblical text as divine revelation helped them avert the suspicions aroused by Jewish Aristotelians and Averroists—followers of the 12th-century Arabic Aristotelian philosopher Averroës (1126–98)—and, in time, even won for them the status of a rabbinic elite. Indeed, in the early 13th century some of the mystics lent their support to a campaign that condemned the study of philosophy as generating skepticism, latitudinarianism, and disrespect for traditional literature.
