History of the Jews in Azerbaijan
The history of the Jews in Azerbaijan dates back many centuries. Today, Jews in Azerbaijan mainly consist of three distinct groups: Mountain Jews, the most sizable and most ancient group; Ashkenazi Jews, who settled in the area during the late 19th – early 20th centuries, and during World War II; and Georgian Jews who settled mainly in Baku during the early part of the 20th century.
