"Fatimid Egypt (with North Africa) by the tenth century took over an important part of the India trade from their rivals in Iraq. The result was a vast migration of Jews to Cairo. When Baghdad declined and the Abbasids began to lose more and more power in the east and in the west, from the late tenth century and especially after the Seljuq invasion and the beginning of the Cru­sades (1096), an even larger portion of the India trade was redirected to Egypt. In Egypt the Jews again obtained a disproportionate share in this trade in the eleventh and twelfth centuries, when it became one of their main pursuits. Jewish trading stations, linked to Egypt and the Red Sea termini, can be located in over twenty different places on the westcoast of India, to the south of Broach, and further in Indonesia. And in Egypt too the Jews sometimes attained high positions at court. But they were no longer as dominant as they had been in Baghdad, and the India trade of the tenth to twelfth centuries which is described in the Cairo Geniza documents was carried out and financed to a far greater degree by Mus­lims based in the Mediterranean area.83 Still, Cairo became an increas­ingly important centre of Jewish mercantile and financial activity. Egypt - Egyptian Muslims and Egyptian jlw ry - became the new in­termediary between the Mediterranean and the Indian Ocean, with the old Babylonian centre receding to the background."
