The Federation of Arab Emirates of the South is created as a protectorate of the United Kingdom.

The Federation of the Emirates of South Arabia was an organization of states within the British Aden Protectorate in what would become South Yemen. The Federation of six states was inaugurated in the British Colony of Aden on 11 February 1959, and the Federation and Britain signed a “Treaty of Friendship and Protection,” which detailed plans for British financial and military assistance. It subsequently added nine states and, on 4 April 1962, became known as the Federation of South Arabia. This was joined by the Aden Colony on 18 January 1963.

A protectorate, in the context of international relations, is a state that is under protection by another state for defence against aggression and other violations of law. It is a dependent territory that enjoys autonomy over most of its internal affairs, while still recognizing the suzerainty of a more powerful sovereign state without being a possession. In exchange, the protectorate usually accepts specified obligations depending on the terms of their arrangement. Usually protectorates are established de jure by a treaty. Under certain conditions—as with Egypt under British rule (1882–1914)—a state can also be labelled as a de facto protectorate or a veiled protectorate.

February 11 is the 42nd day of the year in the Gregorian calendar; 323 days remain until the end of the year.
