Query: A reasonably good basic history, but lacking in some areas.

Cunningham is a an exceptional scholar, and he has made a name for himself in African studies. His book on Portugal, however, is lacking. Some portions are not fully based on verifiable fact. Several of his opinions are quite streched, and he is anthropologically incorrect when he refers to the Portuguese as a race. The Portuguese are not a race. They are a PEOPLE within the caucasian race.
