Burden of Empire [EPUB ebook] 
An Appraisal of Western Colonialism in Africa South of the Sahara

Since its publication in 1967, Burden of Empire has been widely praised and criticized for its controversial approach to the problem of colonialism in Africa. The authors have challenged the new "orthodoxy" about Africa-the belief that little but evil and exploitation has resulted from the era of European colonialism.
