Dushanbe is the capital and largest city of Tajikistan. As of January 2020, Dushanbe had a population of 863,400 and that population was largely Tajik. Until 1929, the city was known in Russian as Dyushambe, and from 1929 to 1961 as Stalinabad, after Joseph Stalin. Dushanbe is located in the Gissar Valley, bounded by the Gissar Range in the north and east and the Babatag, Aktau, Rangontau and Karatau mountains in the south, and has an elevation of 750–930 m. The city is divided into four districts, all named after historical figures: Ismail Samani, Avicenna, Ferdowsi, and Shah Mansur.
In ancient times, what is now or is close to modern Dushanbe was settled by various empires and peoples, including Mousterian tool-users, various neolithic cultures, the Achaemenid Empire, Greco-Bactria, the Kushan Empire, and the Hephthalites. In the Middle Ages, more settlements began near modern-day Dushanbe such as Hulbuk and its famous palace. From the 17th century to the early 20th, Dushanbe began to grow into a market village controlled at times by the Beg of Hisor, Balkh, and finally Bukhara.
