It is frequently remarked that Africa is so diverse as to defy generalization. Perhaps one generalization that can legitimately be made is that today there exists in every sphere of government in every African country a “development consciousness,” preeminent within this consciousness a dependence on economic planning for growth. The historical lessons of Europe and America are proffered and the lessons are studied and more than occasionally applied in the African setting. The Euroamerican historical record is rich and ripe for study; the African record of economic history, on the other hand, nearly does not exist. The embarrassing lacunae of historical work on the economies of Africa is pronounced, whether one is speaking of the transitional economies which through increased trading links first bridged world and African communities in perhaps an irreversible way, or whether one is speaking of the colonial economies of increased dependence, or of the “development economies” of more recent years. And there is irony here, for when seen against the often thin character of the pre-colonial historical record, work on the economic features of pre-colonial Africa seems relatively more substantial than work on the colonial and post-colonial periods.
