It is a familiar fact that European rule in Africa has set in motion a radical change in African society. In some fields this has not been the result of any deliberate intention. In that of economic development, interest has generally been centred in the immediate problems of production, and the effects upon African institutions of the solutions that have been found for these have been neither planned nor even foreseen. But in the field of politics, European governments have been obliged to define their intentions towards the authorities whom they found already in existence, and here, in theory, there was a clear-cut choice from the start. Either the holders of power in the indigenous societies should be recognized, and utilized as part of an administrative structure of larger scale, or they should be disregarded–their authority be perhaps deliberately destroyed–and replaced by what M. Albert Sarraut once called ‘new and rectilinear architectures’. The British chose the first course, and this policy has now become inseparably associated with the name of Lugard. I believe that the forthcoming work by Miss Margery Perham will show that what has been called ‘Lugardism’ in the derogatory sense–I mean the insistence on maintaining traditional authority almost for its own sake–was not Lugard's own philosophy, but that of the successors who were in command during the period when he was away from Nigeria.
