This collection chronicles the most critical decade witnessed to date in the territorial evolution of the Arabian Peninsula and Gulf region, a wholly unique area in geopolitical terms. Nowhere else is there such a concentration of microstates and these overlie the world's greatest concentration of hydrocarbon reserves, all within a semi-enclosed sea. The illuminating Foreign and Commonwealth Office documents included here comprehensively chart the huge efforts made by Britain to get its territorial house in order by the time it left the region as protecting power in December 1971 but also provides unique insights into the major settlements of the era and their background. The records presented include treaties, letters, telegrams, memoranda and notes, the latter often being diplomatic summaries and assessments. The subject matter being dealt with here includes negotiations, agreements, disputes, incursions and claims. This 18-volume set includes 2 map boxes containing 30 large folding maps showing boundary agreements.
