Anti-Jewish acts were sometimes linked to resentment of European powers.[50] In this time Iranian Jews who were aware of the growing influence of European Jews in global affairs turned to them for assistance. In 1840 the Jewish community of Hamedan sent an envoy, Nissim Bar Selomah, to meet Western Jewry. He went to England and met with Moses Montefiore, who provided "certificates" against the accusations of the Jews.[51]
