Oman has received a lot of academic interest due to its strategic position, but its relationship with Britain has not really been covered. Oman and Britain have a long-standing relationship which has changed over time. Now it would appear the relationship is diminished from the high involvement of the 1950s-1970s. This book analyses the relationship from the 1950s until the present day and considers how it has changed. It will use new forms of dependency theory – “Security Dependency” and “Voluntary Dependency” to explain the relationship arguing that up until Oman''s acquisition of full independent status in 1977 it was one of security dependency. Following Britain''s official withdrawal in 1977, the work will show the relationship continues to be dependent. This dependency however has moved from security dependency to voluntary dependency. This book considers the events of Oman''s two major rebellions, Jebel Akhdar and Dhofar, as well as Sultan Qaboos'' succession and the formation of the army to show this “security dependency”. It then examines the continuation of the British relationship and the alternatives offered to Oman to showcase “voluntary dependency”.
