Geonim Confront Apostasy: Legal Consequences of Conversion to Islam (9th-11th Centuries)
The leaders of the Babylonian Jewish community were confronted by a new reality in the wake of the Muslim conquests of the mid-7th century: In contrast to the previous state religion, Zoroastrianism, Islam welcomed converts and made conversion attractive in various ways. Although we have no statistical data on the frequency of conversion from Judaism to Islam, Geonic responsa addressed to Jewish communities throughout the Islamic world, dealing with the consequences of conversion in personal and civil law, clearly show that this was a significant phenomenon and that halachic authorities engaged in vigorous debates with regard to these consequences.
