Biography
Born in Germany sometime in the early 15th century, Sarfati was originally of French descent (his surname "Sarfati" צרפתי means "French" in Hebrew). Not much is known of his early life but in c. 1453, Sarfati moved to the Ottoman Empire where he was eventually made the Chief Rabbi of Edirne. That following year, he sent out a letter to the Jews of the Rhineland, Swabia, Styria, Moravia, and Hungary in which he spoke with great enthusiasm of the fortunate conditions of the Jews under Ottoman control, stating; "I proclaim to you that Turkey is a land wherein nothing is lacking, and where, if you will, all shall yet be well with you." The following years witnessed a massive emigration of Jews to the Turkish lands, considered the third main wave of Jewish immigrates to Turkey.
