Bukhara בּוּכָרָה

What is documented, ranked by evidentiary weight. Early fourth century: Samuel bar Bisena of Pumbedita travels to Merv—the earliest textual notice of Jews in Central Asia. Fifth to seventh centuries: graves near Bayram-Ali in the Merv oasis with inscriptions in Hebrew script—the earliest material evidence. Around 781–790: the Judeo-Persian letter from Dandan-Uiliq near Khotan, recovered by Aurel Stein in 1901—a merchant's letter about sheep, cloth, bribes and war news from Kashgar; the paper dates to 781–790. By the tenth century a distinct Minhag Khorasan is attested, that is, an established regional liturgy of its own. Thirteenth century: the first explicit mention of Jews in the city of Bukhara itself. 1338: Solomon ben Samuel completes a Judeo-Persian dictionary. Around 1590 Jewish silk workers captured in north-eastern Iran are forcibly resettled at Samarkand and Bukhara. By 1620 Bukhara has a synagogue and a Jewish quarter, Maḥalla-ye Kohna, "the old quarter."

The honest formulation: Jews in Central Asia from late antiquity; in the city of Bukhara from the thirteenth century. The gap between those dates is real and should not be papered over. The legend of descent from the Ten Tribes, and of the biblical Ḥabor (2 Kings 17:6) being Bukhara, is recorded in the Jewish Encyclopedia of 1906 as the community's own claim, not as the editors' finding; the etymology has no philological basis.

Chala (Tajik, "neither this nor that")—Bukharan Jews coerced into Islam from the late eighteenth century: outwardly Muslim, inwardly Jewish. By the 1830s they were about thirteen per cent of Bukhara's Jewish population. Return was impossible: apostasy from Islam in the emirate carried the death penalty—and that survived after the Russian conquest, because the Emirate of Bukhara remained a formally autonomous protectorate. So chala crossed illegally into Russian Turkestan, where reversion was possible. After 1920 the passport nationality line let their descendants register as Uzbeks and Tajiks, and most passed permanently into the Muslim population.

The Russian conquest—Tashkent 1865, Samarkand 1868—and the treaties of 1868 and 1873 gave Jews equal rights of settlement and trade in Russian territory. The subtlety usually missed: the emirate's internal legal order, the restrictions and the death penalty for apostasy included, survived the conquest. Emancipation was geographic, not legal: a Bukharan Jew acquired rights by moving. The Trans-Caspian railway, built between 1880 and 1905, ended commercial isolation and made the first aliyah possible.
