Destroy? 'Migrate'? Conceal? British Strategies for the Disposal of Sensitive Records of Colonial Administrations at Independence

Publicity given in 2011 to the existence of a Foreign and Commonwealth Office 'migrated archive', now known also as the 'Hanslope disclosure', following a High Court demand for release of records relative to a case brought by former Mau Mau detainees, led me to explore files already in the public domain which might throw light on British policy towards the 'disposal' of locally created records of colonial administrations at independence. This article examines Colonial Office and Commonwealth Relations Office files concerned primarily with Kenya, Tanganyika, Nigeria and the Central African Federation, but which reveal much about policy and practice not only in sub-Saharan Africa, but also in Southeast Asia. Reasons for refusals to pass material to successor independent governments, and the underlying security concerns, are spelled out in the records; some indication of the volume of records destroyed or sent to London is given; methods of destruction and transmission are discussed; deliberate misinformation given to local politicians and officials is admitted; and tensions between the Foreign and Commonwealth Office and the Public Record Office, and between political expediency and archival practice, are revealed. The article continues with a discussion of ultimately inconclusive deliberations led by UNESCO in the 1970s and 1980s which sought the return of, or access to, 'migrated' records 'in the search of historical truth and continuity'.
