Leon Poliakov writes that in the early ages of Islam, Jews enjoyed great privileges, and their communities prospered. No laws or social barriers restricted their commercial activities, and exclusive trade and craft guilds like those in Europe did not exist.
Jews and Muslims in the eastern islamic world (7th–13th centuries) The history of Jews and Muslims in the Eastern Islamic world highlights the profound impact Islamic rule had on Jewish communities. For much of the medieval period, "the Jewish communities of the Islamic world were responsible for many of the institutions, texts, and practices that would define Judaism well into the modern era". Islamic governance shaped the intellectual, demographic, and economic conditions of Jewish communities, fostering a cultural environment where Judaism consolidated and thrived. "For Jews, after the initial cataclysm of conquest, Islamic rule presented a relief from theologically based oppression" (from Byzantine empire). Islamic governance also allowed Jewish communities to participate in the intellectual and cultural advancements of the empire.
Conquests and governance Following the Islamic conquests of the 7th century, the Rashidun, Umayyad, and Abbasid caliphates unified vast territories, including regions with significant Jewish populations such as the
Levant,
Mesopotamia, and
Egypt. This political unity facilitated Jewish migration and established consistent legal statuses across the empire. "The early stages of the Islamic conquests brought the Jewish populations of the Near East under a single empire that maintained its political unity for three centuries—and its cultural unity for much longer".
Migration and urbanization Jewish populations shifted, increasingly toward urban centers, driven in part by economic opportunities and the imposition of land taxes (kharāj) on non-Muslims. "Urbanization itself thus made life for peasants more difficult, and ultimately, the burden of subsistence farming and the increasing viability of earning a livelihood through crafts and trade encouraged many to move to towns and cities".
Baghdad,
Fustat, and
Jerusalem were centers of Jewish life and cultural exchange.
Integration with urban elites Jewish professionals often occupied urban professions, including roles as merchants, scholars, and courtiers. By the 10th century, Jewish elites played significant roles in commerce and administration. "The cities of the Islamic Empire became centers of territorial bureaucracies, and interurban links themselves tended to encourage geographic mobility and the tighter integration of the elites". Social integration allowed Jews to make great advances in new fields, including mathematics, astronomy, philosophy, chemistry and philology, with some even gaining political power under Islamic rule. For example, the
vizier of
Baghdad entrusted his capital to Jewish bankers, Jews were put in charge of certain parts of maritime and slave trade, and
Siraf, the principal port of the caliphate in the 10th century, had a Jewish governor. Jews who moved to Muslim lands found themselves free to engage in any profession, resulting in less stigma than in Europe where such restrictions were still in force.
Linguistic and literary advances Arabic became the lingua franca for Jews in the Islamic world, often written in Hebrew script as Judeo-Arabic. "For Jews, Arabic took the form of Judeo-Arabic, a range of Arabic registers and dialects written in Hebrew characters that served as a koine, enabling Jews across vast distances to communicate with each other". This period also saw significant developments in Hebrew linguistics, inspired by Arabic grammatical sciences.
Innovations in written culture The introduction of paper and the codex revolutionized Jewish textual traditions. The Abbasid Caliphate’s promotion of papermaking enabled the widespread production of books and documents. "Paper totally transformed written culture all over the Islamic world... By the mid-tenth century it had become the preferred medium for both everyday and scholarly writing in the Islamic world". This technological shift facilitated the preservation and dissemination of Jewish texts, including the Babylonian Talmud, legal codes, and literary works. The Cairo Geniza, a trove of medieval Jewish manuscripts, provides invaluable insights into this period.
Taxation and economic policies Islamic taxation policies, including the kharāj (land tax) and jizya, influenced Jewish economic activities. While these taxes placed financial burdens on non-Muslims, they also incentivized urban migration and engagement in trade and crafts. "The kharāj was a collective tax, and that meant that when individuals fled to cities, they increased the tax burden on those who remained behind".
Organization of communities Jewish communities under Islamic rule were organized along religious lines, with local leaders overseeing communal affairs. These leaders, often titled muqaddam or ra’īs al-yahūd (head of the Jews), managed taxation, charity, and legal disputes. They also served as intermediaries between the Jewish community and Islamic authorities. "The Jewish communities distributed charity, ransomed captives, collected taxes and fees, adjudicated disputes through a system of courts and legal specialists, and elected and appointed leaders".
The role of the geonim The geonim of Mesopotamia and Palestine were central figures in Jewish religious life. They provided guidance on religious practices, resolved disputes, and maintained connections with Jewish communities across the Islamic world. "Responsa came to constitute the primary literary output of the yeshivot and their most important means of contact with their followers".
Political fragmentation The decline of the Abbasid Caliphate and the rise of regional powers, such as the Fatimids and Umayyads, reshaped the political landscape of the Islamic world. This fragmentation impacted Jewish communities, shifting centers of Jewish life to new regions, including Egypt and al-Andalus. "Paradoxically, [political fragmentation] furthered [cultural unification], for one main reason: the crisis in the Iraqi heartland sent waves of migrants westward, and those migrants brought Iraqi customs and culture with them".
Anti-Jewish legislation While Jews generally experienced tolerance under Islamic rule, periods of political instability and economic decline occasionally led to discriminatory policies.
Cultural influence - Sanctity of Jerusalem In early Islamic history, some Muslim scholars viewed the sanctification of Jerusalem as a possible Judaizing influence, introduced by Jewish converts like Kaʿb al-Aḥbār. A well-known anecdote recorded by Ṭabarī depicts Caliph ʿUmar rebuking Kaʿb for suggesting the Rock as the site of Muslim prayer, accusing him of following Jewish traditions. This reflects an early resistance among theologians who rejected Jerusalem's sanctity in Islam, considering it a deviation from the exclusive focus on Mecca. Such views, however, gradually lost prominence. Over time, particularly following the Crusades and later European interventions, Jerusalem’s status as Islam’s third holiest city became widely accepted.
Jews during Fatimid rule (909–1171) The Fatimid Caliphate (909–1171), an Isma'ili Shia dynasty that ruled over North Africa, Egypt, and parts of the Levant, significantly influenced Jewish communities within their territory. The Fatimids, particularly under Caliph al-Mu'izz li-Din Allah (r. 953–975) and his successors, generally adopted a policy of tolerance toward non-Muslims, including Jews, in accordance with the
dhimma system, which granted them legal protection in exchange for a special tax (
jizya).
Political fragmentation and migration By the mid-tenth century, the Abbasid Caliphate faced military and fiscal crises, leading to political fragmentation. The rise of the Fatimids further destabilized Abbasid authority, and by 969, they had conquered Egypt, shifting the center of Islamic power westward. This had significant consequences for Jewish communities, as migration from Iraq to Egypt increased, spreading Iraqi Jewish customs and traditions westward. Jewish communities in Egypt and Palestine absorbed cultural influences from Iraq, creating a more unified Jewish identity across Fatimid territories. Egypt’s economic and political rise under the Fatimids made it a desirable destination for merchants, scholars, and state officials. By the twelfth century, Fustat and Cairo had become the most important Jewish centers in the east, rivaling the Iberian Peninsula in the west. The arrival of Maimonides in Egypt around 1165 marked the culmination of this shift, as he became the de facto leader of Egyptian Jewry and one of the most influential Jewish scholars of the Middle Ages.
Jewish life in Egypt and trade networks During the Fatimid period, Egypt became a major center of Jewish life. Cairo, especially the area around Fustat, housed a vibrant Jewish community engaged in trade, crafts, and administrative roles. Jewish merchants, particularly those involved in long-distance commerce, benefited from the security and stability provided by the Fatimid state. The Geniza documents from the Ben Ezra Synagogue in Fustat reveal extensive Jewish participation in Mediterranean trade networks, with correspondence between merchants in Egypt, North Africa, and even India. One of the most notable Jewish merchant groups of this period were the Radhanites, who operated extensive trade networks spanning from Western Europe to China. Described in the ninth century by the Abbasid geographer Ibn Khurradadhbih, the Radhanites were multilingual and traded in luxury goods, including slaves, furs, textiles, weapons, and spices. While their presence predated Fatimid rule, Jewish merchants in Fatimid territories continued to play a crucial role in international trade, as evidenced by later Geniza documents. The Fatimid conquest of Egypt and the shift of the Islamic economic center westward further strengthened Jewish participation in commerce, as Cairo became a key hub in Mediterranean and Indian Ocean trade. The Fatimid court occasionally appointed Jews to high-ranking positions. Yaqub ibn Killis, a Jewish convert to Islam, became vizier under Caliph al-Aziz Billah (r. 975–996) and played a crucial role in state administration. Despite these opportunities, Jews, like other
dhimmis, faced occasional persecution. Under Caliph al-Hakim bi-Amr Allah (r. 996–1021), harsher policies were briefly implemented, including the destruction of synagogues and restrictions on religious practice, though these measures were later reversed. The Jewish community in Fatimid lands was closely linked to the academies in Iraq. The heads of the Babylonian yeshivot (
geonim) maintained extensive correspondence with Jewish communities in Egypt, providing legal and religious guidance. The position of
nagid (leader of the Jewish community) emerged in Egypt under Fatimid rule, consolidating Jewish leadership within the empire.
The Jews in Al-Andalus (711–1492) The Jewish communities of
al-Andalus thrived during the period of Muslim rule on the
Iberian Peninsula, particularly between the reign of
Abd al-Rahman III (912–961) and the Almohad conquest after 1140. This era, often referred to as a "Golden Age," saw an unprecedented flourishing of Jewish culture, intellectual life, and political influence. Despite earlier persecution under the Visigoths, when Jews "lived in great social and legal insecurity" and faced forced conversions, the Jews of al-Andalus embraced Arab culture and language, enabling their integration and the development of a rich literary tradition. This unification under Arabic culture, "constituted a fundamental change" that facilitated communication and cooperation among Jewish communities and strengthened their cohesion. Prominent Jewish figures held high-ranking positions in political and economic spheres, with some serving as viziers, diplomats, and advisors to Muslim rulers.
Hasdai ibn Shaprut, described as "surpassing all the royal servants in his manners, intellectual discipline, subtlety, patience, and intelligence," played a key role in the
Umayyad court, where he also contributed to the importation of Hebrew texts from the East.
Samuel ibn Naghrillah, a Jewish vizier and poet, exemplified the close interweaving of Jewish and Arabic cultural elements. His collected works reflect his engagement with both the intellectual and political life of al-Andalus. Despite the significant achievements of Jewish communities in al-Andalus, episodes of persecution revealed the fragility of their position. The
1066 Granada massacre (the razing of the entire Jewish quarter in the
Andalucian city of
Granada) marked a particularly violent moment when Joseph ha-Nagid, a prominent Jewish vizier, was assassinated. This event led to widespread looting and the killing of many members of the Jewish community. Similarly, the Almohad dynasty’s rise in the mid-12th century imposed forced conversions to Islam, causing many Jews to flee to Christian territories in the north or to Islamic regions such as Morocco and Tunisia. According to some Arabic sources, even those who converted faced suspicion and were required to wear distinctive clothing to identify themselves. The philosopher Maimonides, one of the most notable Jewish figures of the era, was among those who emigrated during this period, epitomizing the broader Jewish diaspora prompted by these events. In 1465, a mob enraged by stories about the behavior of a Jewish
vizier killed many of the Jews and the Sultan himself. The community was temporarily converted but soon reverted to Judaism. Hebrew poetry of the period adopted Arabic meters, genres, and forms, granting Hebrew a new cultural status beyond its traditional use as a sacred language. The Jewish aristocracy in al-Andalus also mirrored the manners and values of their Muslim counterparts, participating in poetry contests, composing qasidas in Hebrew, and engaging in intellectual debates. Grammarians and philologists, such as Yehuda Hayyuj, made groundbreaking advances by applying Arabic linguistic principles to Hebrew, which enriched the understanding of biblical texts. These efforts exemplified the synthesis of Arabic and Jewish intellectual traditions. The period’s integration of Arabic and Hebrew thought also extended to fields such as philosophy, where figures like Maimonides and Shlomo ibn Gabirol produced works that resonated across Jewish and Islamic scholarly traditions.
Almohad (1121–1269) persecution of Jews in north Africa The Almohad Caliphate, ruling parts of North Africa and the Iberian Peninsula during the 12th and 13th centuries, subjected Jewish communities to widespread persecution. Under Almohad rule, synagogues were destroyed, Jewish practices were outlawed, and forced conversions to Islam were imposed. Almohad chronicler
ʿAbd al-Wāḥid al-Marrākushī noted that “no church or synagogue is to be found in the entire Maghreb” and described Jews outwardly practicing Islam while secretly maintaining their faith at home. Jewish sources provide a mixed perspective on these events. While some, such as
Abraham Ibn Daʾūd, depict the Almohad persecutions as a program of mass forced conversion, others, like
Maimonides, suggest that these conversions often involved verbal declarations that did not deeply disrupt Jewish life. In his
Epistle on Martyrdom, Maimonides described forced conversions as superficial and advised Jews to preserve their faith secretly rather than face martyrdom. However, Mark R. Cohen, claims that “Maimonides’s famous statement “[n]o nation has ever done more harm to Israel” than Islam […] reflects the great sage’s own recent experience of Almohad persecution in his native Spain and Morocco.” The persecutions led to significant theological reflections within the Jewish community. While earlier Islamic regimes were relatively tolerant, the Almohad period marked a profound shift, forcing Jews to reconsider their relationship with Islam and their theological understandings of suffering. Some, like Joseph Ibn ʿAqnīn, regarded the Almohad era as one of the most devastating periods in Jewish history, and he argued for migration to more tolerant lands as a solution.
