Tajik Soviet Socialist Republic
Part of the Khanate of Bukhara since the 16th century (the Emirate of Bukhara since the 18th century), the city changed its name from Khatlon to Kulob in 1750. Following the Russian conquest of Central Asia and the creation of the Tajik Soviet Socialist Republic within the USSR in 1929, Kulob became one of the largest cities in the republic.
