History of the Jews in Makhachkala
The Jewish community in Makhachkala consists of Jews who have lived in the territory of modern Makhachkala, a city in the Russian Republic of Dagestan. During the Persian campaign in 1722, Makhachkala hosted a camp for the troops of Russian Emperor Peter I. Both Mountain Jews and Ashkenazi Jews were allowed to settle there.
