The Jewish community of Rhodes appealed for help from the Jewish community in Constantinople, who forwarded the appeal to European governments. In the United Kingdom and Austria, Jewish communities gained support from their governments. They sent official dispatches to the ambassadors in Constantinople unequivocally condemning the blood libel. A consensus developed that the charge was false. The governor of Rhodes sent the case to the central government, which initiated a formal inquiry into the affair. In July 1840, that investigation established the innocence of the Jewish community. Finally, in November of the same year, the Ottoman sultan issued a decree ("firman") denouncing the blood libel as false.
