German scholars contributed an impressive amount to many different disciplines in their studies of German East Africa and other German colonies, particularly between about 1890 and 1910. Much research was undertaken and a considerable amount was published. Then, after the First World War, when Germany lost her colonies, some valuable work was abandoned. One important project which suffered was the collection of data on customary law in the former German colonies. The sets of answers to a questionnaire were the main source used in compiling a large two volume study, Das Eingeborenenrecht (1929 and 1930), which is available in research libraries outside Germany. However, the original printed sets of answers are a more valuable source of ethnographic and legal data than the book; but they are little known and appear to have been generally unavailable outside Germany and Tanganyika. Rhodes House Library, Oxford, now has a copy of the original German questionnaire and a microfilm of the sets of answers for German East Africa. The purpose of this article is to explain how the original German research project developed, to present an English translation of the final version of the questionnaire (see Appendix A, below), a check list of the most important facts about each of the sets of answers collected in German East Africa (see Appendix B, below), and a brief assessment of the value of this data.
This research is interesting when it is seen from any of the following points of view;
