Emirate of Dhala Wikipedia
Previously Dhala' was under the suzerainty of the Zaidi imams of Yemen, the emirs of Dhala, of the Amiri dynasty. In 1904 it became a British protectorate, eventually joining of the Aden Protectorate.
The Emirate was a founding member of the Federation of Arab Emirates of the South in 1959, and the Federation of South Arabia in 1963.
The Radfan Hills, nominally under control of the Amiris of Dhala, were the scene of fierce fighting between British forces and the local Qutaibis during the Aden Emergency in the mid-1960s.
The last emir, Shafaul ibn Ali Shaif Al Amiri, was deposed and the state was abolished in 1967 upon the founding of the People's Republic of South Yemen.
The area is part of the Republic of Yemen since 1990.
