مستعمرة عدن
In 1937, the settlement was detached from India and became the Colony of Aden, a British Crown colony. The change in government was a step towards the change in monetary units seen in the stamps illustrating this article. When British India became independent in 1947, Indian rupees (divided into annas) were replaced in Aden by East African shillings. The hinterland of Aden and Hadhramaut were also loosely tied to Britain as the Aden Protectorate, which was overseen from Aden.
