Nakhichevan-on-Don

Nakhichevan-on-Don (, "Naxičevan’-na-Donu"), also known as New Nakhichevan (, "Nor Naxiĵevan"; as opposed to the "old" Nakhichevan), was an Armenian-populated town near Rostov-on-Don, in southern Russia founded in 1779 by Armenians from Crimea. It retained the status of a city until 1928 when it was merged with Rostov.
History.
In the summer of 1778, after the Crimean Khanate was made a Russian vassal state, some 12,600 Armenians of the Crimean peninsula were resettled by General Alexander Suvorov in the Don region. The Russian Empire sought to strengthen Novorossiya, which was vital in completely absorbing the Crimea. Empress Catherine the Great granted some 86,000 ha of land to the Armenians by a November 14, 1779 decree. A third of the Armenians perished en route and during the first winter. The settlement of New Nakhichevan was founded by the survivors. It "rapidly grew into an important town with its own cathedral and seminary."
In 1894 the Armenian community erected the Alexander Column in Nakhichevan-on-Don to celebrate the Emperor Alexander II of Russia.
Around the turn of the twentieth century it was part of the Don Host Oblast. In 1896 it had an estimated population of 32,174, of which 14,618 (45.4%) were native residents and 17,556 (54.6%) were nonresidents. The Armenian Apostolic population was estimated at 18,895 (58.7%), Orthodox at 10,965 (34.1%), others (Jews, Old Believers, Muslims, Catholics, Protestants) at 2,314 (7.1%). According to the 1897 Russian Imperial census the city had a population of 28,427. East Slavic-speakers (Russians, Ukrainians and Belarusians) made up around two-thirds of the population (19,224), while Armenians (8,277) comprised a significant minority (29.1%).
Merger with Rostov and later history.
By the late 19th century it was "engulfed by the growth of Rostov". As early as in the 1897 article about the city in the "Brockhaus and Efron Encyclopedic Dictionary" wrote: "Currently, Nakhichevan-on-Don has merged with Rostov so that the boundaries of the two cities can only be determined by a plan approved May 11, 1811." On December 28, 1928, Nor Nakhichevan was officially made part of Rostov. In 1929 Rostov's largest district—Proletarsky raion (Пролетарский район) was established on its location. As of 2001, it amounted to a "kind of Armenian quarter within the city." According to the 2010 Russian census, of the 41,553 Armenians in the city of Rostov-on-Don, 10,008 or almost 25% of all Armenians live in the Proletarsky district, where they make up more than 8% of the population, well above the city's total percentage of Armenians (at 3.8%).
