In the half century preceding imperial control approximately eight hundred Britons lived and travelled in East and Central Africa.
Prelude to Imperialism
(1965) examines their relations with and attitudes to African tribal societies. The author presents a broad survey of tribal life, an analysis of culture contact, and an extended discussion of the underlying assumptions of the British evaluation of Africans and of the conditions in which they lived. The description of African social conditions and the analysis of grass roots imperialism constitute important contributions to the debate on Western imperialism.
