The Mountain Jews speak Juhuri, or Judeo-Tat language, which is closely related to Modern Persian; it belongs to the Iranian division of the Indo-European languages. A similar, but still different language is spoken by the Tats of Azerbaijan, a group to which the Mountain Jews have sometimes been considered to belong. In the early 20th century Judeo-Tat used the Hebrew script. In the 1920s Latin script was adapted for it; later it was written in Cyrillic characters.
There is some debate on the origin of the
Jewish Tats, with some defending that they are not Tat at all but
simply Jews that
took the Tat language, while others argue that they are the descendants
of Tats that converted to Judaism.
Any specific Mountain Jew features, distinguishing them from the Islamic environment, originate in Judaism. In the villages (aouls) the Mountain Jews settled in a part of their own, in towns they did the same, although their dwellings did not differ from their neighbours'. The Mountain Jews also took to wearing the highlanders' dress. Judaistic prohibitions ensured they retained specific dishes and faith still enshrined in the rules for family life.
If elsewhere in the Jewish diaspora it was forbidden to own and till land (cf. the Jews of Central Asia), at the end of the 19th and the beginning of the 20th century the Mountain Jews were farmers and gardeners growing mainly grain. Their oldest occupation was rice-growing but raising silkworms and tobacco was also popular. The Jewish vineyards were especially famous. The Jews and their Armenian neighbors were the main producers of wine, an activity banned for Muslims by religion. Judaism, in turn, strictly limited any meat consumption and unlike their neighbours the Mountain Jews raised few domestic animals.
At the same time they were renowned tanners. Tanning was the third most important activity after farming and gardening and at the end of the 19th century 6% of Jews were engaged in this trade. Handicrafts and commerce were mostly practiced by Jews in towns.
The Soviet authorities bound the Mountain Jews to collective farms but allowed them to carry on in their traditional ways (they grew grapes, tobacco and vegetables and made wine). However, the former isolated lifestyle of the Jews has practically been eradicated and they now live side by side with other ethnic groups.
Originally education was only for the boys who attended synagogue schools. With sovietization, Tat became the language of tuition at newly-founded elementary schools. It remained so till the beginning of World War II. The publication of the first native-language newspaper, Zakhmetkesh (Working People), began in 1928. After the war Russian became the only acceptable language at Dagestan schools and the publication of the newspaper stopped. Today Mountain Jewish intellectuals are active in the Dagestan cultural scene. Several of them are prominent actors and artists and there are writers and poets. However, only amateur theatricals and concerts are there to highlight their ethnic culture. Mountain Jewish cultural activities in Azerbaijan are suppressed by flourishing Azerbaijani chauvinism.
