In 1926, municipal authorities adopted a new city layout designed by Aleksandr Tamanian; two additional designs for expansion were approved in the 1930s and 1960s, both of which retained Tamanian's initial plan. Several schools and two polyclinics were established, and an Armenian drama theater was founded in 1932 and named after Maxim Gorky. Stepanakert served as Nagorno-Karabakh's main economic hub, and by the mid-1980s there were nineteen factories in the city.
