Developments within the two major Jewish communities of medieval Europe were complicated by their uncertain relationship with the Christian community surrounding them. By all accounts, Christians and Jews had been on relatively good terms until the 11th century. In the early Middle Ages there were frequent contacts between Christians and Jews, who intermarried and shared language and culture. In the Carolingian era some bishops even complained that the Jews were favoured too much by Carolingian rulers. The situation became more complicated after about the year 1000, as Christian society began a process of reorganization that contributed to the marginalization of the Jews and other groups. Although the Jews did not endure unrelenting persecution and even enjoyed a cultural renaissance in the 12th century that paralleled a Christian one, they faced an increasingly hostile community that created a new theological image of the Jews and undermined the place of the Jews in society.
In the opening decade of the 11th century, Jews in various parts of Europe faced violent attacks and forced conversions that led some, according to one account, to commit suicide rather than accept baptism. Attacks against the Jews and full-scale massacres of Jews would occur throughout the rest of the Middle Ages, most notably at Mainz in the Rhineland in 1096, in England in 1198–90, in Franconia in 1298, and in France in 1320. The image of the Jews among Christians worsened, and numerous anti-Semitic stereotypes appeared in the 12th century. The most notorious example of these was the blood libel, which alleged that the Jews killed Christian boys and used their blood to make unleavened bread.
Meanwhile, official legislation of the church confirmed the declining position of the Jews. Pope Innocent III issued a decretal declaring the Jews to be in perpetual servitude for the killing of Christ, and at the fourth Lateran Council in 1215 the Jews were ordered to wear distinctive clothing, forbidden to hold public office, and prohibited from appearing in public during the last three days of the Easter season. With the discovery and burning of the Talmud by Christians in the 13th century, the church’s view of the Jews worsened, because the church thus became aware that contemporary Jews were different from biblical Jews. The acceptance of the Talmud by the Jews was understood as heretical by the church, which had already launched a Crusade and the Inquisition against Christian heretics. The Jews’ failure to live up to the Christian understanding of them undermined the contemporary theological justification for their continued existence (i.e., until the end of time, as witness to the truth of Christian revelation).
Challenges also emerged in the economic and social order as economic opportunities were increasingly restricted. Although there were Jewish merchants, artisans, and viticulturists throughout much of the Middle Ages, by the 12th and 13th centuries the Jews were limited to the occupation of money lending, which brought some of them great wealth but also great animosity from borrowers. Moreover, the Jews were often an important source of capital for the monarchs of Europe. As an important source of revenue, the Jews provided a valuable service to the kings and thus received special protection in the law. This relationship, however, had an ominous side, as the Jews came to be defined in the law as the personal property of the king, to be exploited as he saw fit. Jews also lost their status as individuals and were secure only as long as they were of utility to their lords.
The declining economic usefulness of the Jews and the related deterioration of their social and religious status led to their expulsion from England in 1290 and from France in 1306. Jews were also expelled from the Holy Roman Empire and, most notoriously, from Spain in 1492. In Spain, anti-Jewish riots in the late 14th century had led to the conversion of large numbers of Jews, the so-called conversos. Spanish Christians, however, remained distrustful of the conversos, who were thought to maintain contact with uncoverted Jews and to practice the Jewish faith secretly. An inquisition established to deal with the conversos led to local expulsions in the 1480s. By 1492, however, the king and queen, Ferdinand II and Isabella I, and their inquisitors decided that the only real solution to the problem was the permanent separation of the conversos and the Jews. The Jews were compelled to choose between baptism and exile, and ultimately some 40,000 (estimates range as high as 800,000) departed Spain, never to return. They settled in Navarre (then outside the kingdom of Spain), North Africa, and Portugal. Many of those in Portugal, however, accepted Christianity as a result of an order of expulsion or conversion there in 1497. Conflicts and new movements
The conflict between philosophers and anti-philosophers in Provence and northern Spain represented a clash between two mature Jewish subcultures of diverse geographic origins, the Sephardic and the Ashkenazic, each of which had in the course of centuries developed different esoteric doctrines to transcend the legalistic formalism and confining dogmas of normative Judaism. Both forms of speculation sought salvation for exceptional individuals through knowledge and thus provided an immediate substitute for messianic deliverance from exile and servitude. Each group charged the other with distortion of tradition, and each issued apologias and excommunications characteristic of medieval doctrinal controversy. While the rifts between them reached bitter proportions, the common threat posed by ecclesiastical attacks on the Talmud in public disputations and by the expulsion of the Jews from France in 1306 prevented open rupture or resolution of the conflict. Ever since that time, two strands of orthodoxy representing the two forms of medieval metaphysical speculation have lived side by side in an uneasy truce.
Most rabbinic circles of the 14th and 15th centuries displayed a progressive dogmatism and insistence on uniformity of practice. The great legal code of Jacob ben Asher of Toledo (c. 1269–c. 1340), Arbaʿa ṭurim (c. 1335; “Four Rows”), which sought to level differences in usage between Ashkenazim and Sephardim, signified the dominant trend of the rabbinate. The increasing hardening of ideological lines, however, did not eliminate independent thinking. Isaac Albalag (13th century) propounded an Averroist (rationalistic) interpretation of the Bible predicated on a theory of double truth (of reason and revelation), while Gersonides (Levi ben Gershom; 1288–1344), gave Jewish Aristotelianism a new and comprehensive formulation. In Muslim areas, the Maimonidean regimen of philosophical contemplation was extended by Maimonides’ son Abraham to a quest for pietist ecstasy that seemed to have much in common with Sufism (Islamic mysticism).
The anti-Jewish riots in Spain and their consequences stimulated the anti-intellectualism of the rabbinate. Crescas" class="md-crosslink">Hasdai Crescas (1340–1410), while conceding the philosophical untenability of traditional belief in free will (see also determinism), launched a scathing attack on Aristotelian approaches to religion, and his disciple Joseph Albo (c. 1380–c. 1444) issued a compendium on dogma that reaffirmed the traditional postulates of divine creation, revelation, and retribution as axioms of Judaism. But these reassertions of traditional faith could not overcome the ideological and social fragmentation that had split the Spanish communities, often leaving them in open conflict with each other. Widespread marranism (ostensible conversion to Christianity) polarized the community and left residues of bitterness toward those returning to the fold (see Marrano). The expulsions from Spain and Portugal drove the leadership into intensified pursuits of mystical escape from, and rationalization of, the endless calamities that befell their flocks. In Italy and the Ottoman Empire (Asia Minor, northeastern Africa, and southeastern Europe)—the two principal centres of refuge for the exiles of the Iberian Peninsula—legalistic Kabbalism, which insisted on strict observance of the law as a precondition of mystical practice and study, became the dominant form of rabbinic leadership. Despite the terrible circumstances, the rabbinate continued to produce works of encyclopaedic proportions and staggering erudition in every field of Jewish learning.
