This 13000 page collection brings together for the first time the detailed reports on what was happening in the British controlled territories of Aden and its hinterland from the beginning of the 20th century to the end of British rule in November 1967. It provides a unique guide to events as they happened on a monthly, weekly, or even a daily basis. The reports were based on firsthand observations by British officials on the spot or on information supplied by informers and travellers from the interior. They covered not only Aden and the Protectorate but the Imamate of the Yemen, the Tihama, and the Asir (now in Saudi Arabia). This information was then sifted and analysed before being passed on to the British authorities in India or London and was the basis on which British Policy in the Gulf was made.
