Historical archaeology in Africa: An appropriate concept?

The term 'historical archaeology' originated in the United States and was subsequently adopted in Canada, Australia, New Zealand, and South Africa, all places subjected to European colonization during the last few centuries. The idea of historical archaeology has had relatively little application in Europe, birthplace of the antithetical idea of prehistory. In Africa, other than at the southern tip of the continent, the practice of what is called historical archaeology has developed only recently and the relevance of the concept in Africa might be questioned. There are chronological problems in its application: not only are the interfaces between preliterate and literate societies spread over thousands of years in different areas but they can at times be regressive. The matter is further complicated if the term historical archaeology is used for societies whose history is oral not written. However, there is an ambiguity in this concept that also has methodological and other connotations. In these respects the idea of historical archaeology does perhaps have a place in Africa as a whole, but it represents a compartmentalization of our discipline still inadequately defined.
