Bergjuden
The Mountain Jews, or Jews of the Caucasus, have inhabited the Caucasus since the fifth century CE. Being the descendants of the Persian Jews of Iran, their migration from Persia proper to the Caucasus took place in the Sasanian era (224-651). It is believed that they had arrived in Persia, from Ancient Israel, as early as the 8th century BCE Other sources, attest that mountain Jews were present in the region of Azerbaijan, at least since 457 BCE However, the Mountain Jews only took shape as a community after Qajar Iran ceded the areas in which they lived to the Russian Empire per the Treaty of Gulistan of 1813.
