Longue durée histories of Angola are thin on the ground and David Birmingham's effort struggles to fill this gap with only partial success. In my personal context I approached it as a companion piece both to his own A Concise History of Portugal and to Malyn Newitt's A Short History of Mozambique.
Indeed, Birmingham in his introduction laments the untimely death of Jill Rosemary Dias and seems almost to apologise that his book is not half the one she may have been piecing together on the same subject. I should very much have liked to read hers but we shall have to live with that disappointment.
Despite its brevity, A Short History of Modern Angola is quite dense and covers a lot of ground. Unfortunately the tone is quite sterile and it doesn't make for the easiest of reading. For a book that's somewhere in the no-man's land between popular history and academic work, it could have been much more engaging without sacrificing the quality of the scholarship.
For example, some more direct quotes from primary sources would serve to encourage a better comprehension of major figures and events, especially in more recent periods with more records on which to draw. Similarly, the almost complete absence of illustrations, photos, and maps rather impoverishes the material and could have livened it up substantially.
As it stands, the experience is definitely one of being told rather than shown the history, which is not the most palatable in concentrated doses. Birmingham also tries to address the problems of history being Euro-centric and even male-centric, though there is a limit to what can be done in this respect without further research and sources.
By comparison, Marion Wallace's A History of Namibia opens with a chapter by John Kinahan detailing the state of archaeological and anthropological research, whereupon both Wallace and Kinahan tied the history and historiography back to this wherever possible. Perhaps Dias might have attempted something similar but Birmingham's book lacks this depth.
The nine chapters (plus an appendix on the adventures of William Cadbury which is essentially a tenth) nevertheless give a solid overview of some of the major events, characters, themes, and geographic complexities of Angola's war-torn colonial and modern history.
