20th Century
In 1920, Soviet Union seized Bukharan part of Gorno-Badakshan. It was merged with Russian part of it in 1924 and was organized as the Gorno-Badakhshan autonomous oblast (province) within the Tajik SSR in 1929, later the Kohistan-Badakhshan Autonomous Province (the official name since 1994) within Tajikistan.
In 1963 Badakhshan included the districts of Baghlan, Pul-i-Khumri, Dushi, Dahan-i-Ghori, Kanabad, Andarab, Kunduz, Hazrat-i-Imam, and Taloqan. In 1963 Qataghan-Badakhshan Province was abolished and since then the territory was dividied into four separate provinces - Badakhshan, Baghlan, Kunduz, and Takhar.
At the height of Taliban strength during the Afghan Civil War, Afghani Badakhashan was a stronghold for Northern Alliance.
