Federation of South Arabia
The Federation of South Arabia ( "") was a federal state under British protection in what would become South Yemen. Its capital was Aden. It was formed on 4 April 1962 from the 15 protected states of the Federation of Arab Emirates of the South. The State of Aden, formerly Aden Colony, joined the Federation on 18 January 1963. In June 1964, the Upper Aulaqi Sultanate was added for a total of 17 states. A team was sent to the 1966 Commonwealth Games in Kingston, Jamaica. The Federation was abolished on 30 November 1967, when its status as  a British protectorate came to an end, along with that of the Protectorate of South Arabia, and they became the People's Republic of Yemen. Postage stamps. The Federation issued its own Adeni postage stamps from 1963 to 1966. Most of its issues were part of the omnibus issues common to all the Commonwealth territories, but it did issue its own definitive stamps on 1 April 1965. The set of 14 included 10 values, from 5 to 75 fils, each depicting the arms of the Federation in a single color, while the top four values (100 fils, 250 fils, 500  fils, and 1 dinar), featured the flag of the Federation. The stamps referred to above are those listed in the Scott Standard Postage Stamp Catalog. A number of other stamps have also been issued and are listed in Stanley Gibbons and other widely used stamp catalogs. It is possible, or even likely, that some of the stamps of South Arabia were not issued primarily for postal use.
