by fifty Sephardic Jewish families from Aleppo. Many of them were Rabbis who were to sit on the Beth Din of Baghdad and Basra. This led to an assimilation of Iraqi Judaism to the general Sephardic mode of observance. Jewish culture revived, with communal leaders as Solomon Ma’tuk being renown for his work as an astronomer, library and piyyutim. This brought the leading Jewish families of Baghdad, and with it, their Jewish practice into the network of Sephardic scribes and later printing presses established in Aleppo, Livorno and Salonica. Surviving records of the contents of the library of Solomon Ma’tuk shows a great number of books purchased from Sephardic scribes and some even originally from Spain. Further driving this process was the high esteem in which Rabbi Sadka Bekhor Hussein was held as a halakhic authority. This saw him accepted as a halakhic authority by the Jews of Persia, Kurdistan and the fledgling Baghdadi trading outposts being established in India. Sephardic Rabbis and their rulings and practices were held in higher esteem. The historian Zvi Yehuda says the period saw the wheels turn in the relationship between the Babylonian Jewish communities and those of Iraq and Persia: “Before the 18th century, the Baghdadi Community needed the support of those communities; now the Baghdadi Community influenced them.” The 18th century saw the Jewish community of Aleppo exert a significant influence over the Jewish communities of Baghdad and Basra not only culturally but economically. Syrian Jewish families establishing themselves in Iraq were often formerly Spanish Sephardic families from Aleppo. These were typically high-class families such as the Belilios family who were frustrated with the dimming prospects of Aleppo and attracted to Baghdad and Basra's booming trade with India. This process saw the leading Jewish families of Baghdad, Basra and Aleppo grow to be heavily interlinked through marriages, religious life, partnership and trade in the 18th century. As this process of cultural assimilation saw the Jews of Baghdad come to more closely resemble the Jews of Aleppo, economic decline in Syria, Kurdistan and Persia worsened. The 18th century saw a growing number of Jews leave from there to Baghdad, Basra or the Baghdadi-led outposts being established in the Far East. The still small and reemerging Jewish community of Baghdad became a migration destination with Jewish families settling in Baghdad from Istanbul, Aleppo, Damascus, Ana and Basra. A key driver of this was decline
