Vahdat is a city in western Tajikistan, on the bank of the Kofarnihon River, 21 km east of Dushanbe. It was previously called Yangi-Bozor (1927–1936), Orjonikidzeobod and Kofarnihon (1993–2006). The current name of Vahdat is a completely new name that was introduced in the 2000s as part of an official renaming of the settlement. Its population is estimated at 43,200 for the city proper and 342,700 for the city with the outlying communities (2020). Vahdat was the focus on international attention in 2019 when a riot occurred in the city's prison, believed to be instigated by members of Islamic State, which led to the deaths of three guards and 29 inmates.
