In the closing paragraph of his inaugural lecture Law and Language, Professor Allott referred to what he termed “a daunting obstacle” to the intensive study of African legal systems.

That obstacle is the rapid disappearance, before our very eyes, of the traditional systems that we have proposed to study. A generation ago there would not have been that difficulty; but today the traditional tribunals have vanished in many African countries where their place has been taken by statutory local courts. Even where the traditional courts appear to have survived, at least in name, they are usually affected by the impact of western law and institutions and of central government control.

Those words were written in 1965. How true and necessary they were is shown by the fact that more than fifty years previously—even more than “a generation ago”—the impact of “western” influences upon the Tswana peoples of the Bechuanaland Protectorate (now the Republic of Botswana) had already led to many changes in the indigenous legal system, although, at that time, the “traditional courts” still survived virtually intact and not merely “in name”.

The nature and extent of those changes can be readily ascertained by the fortunate chance that, there are still available the records of approximately 470 cases tried, over a period of six and a half years, in the highest traditional court of the Ngwaketse, a major Tswana chiefdom.
