A History of the Luo-Speaking Peoples of Eastern Africa by Bethwell A. Ogot

In this book, the author has created a complex and rich narrative – from how the over 1,400 languages spoken in Africa evolved; why occupation has been an important aspect of African perceptions of identity; why certain places were attractive, and how trade routes altered the comparative value of places; and how in turn, trade fostered the development of more complex societies.
