The Letter of the Karaite elders of Ascalon (c. 1100) was a communication written by six elders of the Karaite Jewish community of Ascalon and sent to their coreligionists in Alexandria nine months after the fall of Jerusalem during the First Crusade. The contents describe how the Ascalon elders pooled money together to pay the initial ransom for pockets of Jews and holy relics being held captive in Jerusalem by the Crusaders, the fate of some of these refugees after their release (including their transport to Alexandria, contraction of the plague, or death at sea), and the need for additional funds for the rescuing of further captives. It was written in Judeo-Arabic, Arabic using the Hebrew alphabet.
This and other such letters related to the Crusader conquest of Jerusalem were discovered by noted historian S.D. Goitein in 1952 among the papers of the Cairo Geniza. Goitein first published his findings in Zion, a Hebrew journal, and then presented a partial English translation of the letter in the Journal of Jewish Studies that same year. Since then, it has been retranslated in several other books pertaining to the Crusades. Goitein's final and most complete English translation appeared in his final book posthumously published in 1988.
