مستعمرة عدن
In order to stabilize Aden and the surrounding Aden Protectorate from the designs of the Egyptian backed republicans of North Yemen, the British attempted to gradually unite the disparate states of the region in preparation for eventual independence. On 18 January 1963, the Colony of Aden was incorporated into the Federation of Arab Emirates of the South against the wishes of North Yemen. The city became the State of Aden and the Federation was renamed the Federation of South Arabia (FSA).
