Aden Protectorate
The protectorate included the Hadhrami states of Kathiri, Mahra, and Qu'aiti except the three Wahidi Sultanates in the Eastern Aden Protectorate, with Upper Yafa in the Western Aden Protectorate. The Protectorate of South Arabia was dissolved on 30 November 1967 and its constituent states quickly collapsed, leading to the abolition of their monarchies. The territory was absorbed into the newly independent People's Republic of South Yemen, which became part of the Republic of Yemen in 1990.
