Disputes over the status of Abu Musa and the Tunbs dominate the maritime history of the southern Persian Gulf as recorded for the last hundred years in the archives of the Foreign Office and the British government in India. This collection of primary source material makes available for the first time the vital historical evidence pertaining to the status of the islands. It highlights the interaction of interstate relations and claims, traditional trade and tribal activity and the extent to which natural resources dictate national claims. The issues involve Iran, the UAE, Abu Musa, the Tunbs, the lower Persian Gulf islands and the Strait of Hormuz. These volumes present balanced historical evidence on the long-standing dispute over island sovereignty, documenting successive Iranian claims and also the positions taken by the British government on behalf of the Qasimi shaikhdoms before UAE independence.
