In view of Britain's role in the creation and development of Jordan, bilateral relations in the wake of the Suez crisis are an important test case of its continuing engagement, not only in the Levant, but in the Middle East as a whole. This article shows that despite the far-reaching changes which took place in British foreign policy between 1957 and 1973, Britain retained a significant bilateral relationship with the Hashemite Kingdom. Through a comparison of the role of the Western powers in the 1958 and 1970 crises, and through an analysis of the key events of the intervening years, including the 1967 Arab–Israeli War, this article explores the dynamics of this persisting relationship. It shows that the initiative often came from the Jordanian side, with King Hussein particularly keen to involve both Britain and the United States in the September 1970 crisis as witnesses to his dealings with Israel.
