Dr. Dike has made a contribution to the study of Nigeria's principal formative period by drawing on local as well as British sources for his material. He describes how the revolution in trade reacted upon the social and political systems and how the existing native governments were gradually supplanted by British sonsular power. His study ends with the recognition of the British claim to supremacy in the Niger territories at the Berlin West African Conference of 1885.
Kenneth Onwuka Dike (17 December 1917 – 26 October 1983) was a Nigerian educationist, Igbo Nigerian historian and the first Nigerian Vice-Chancellor of the nation's premier college, the University of Ibadan. During the Nigerian civil war, he moved to Harvard University.[4] He was a founder of the Ibadan School that dominated the writing of the History of Nigeria until the 1970s. He is credited with "having played the leading role in creating a generation of African historians who could interpret their own history without being influenced by Eurocentric approaches."
A book filled with instructive data, but some sections of it were marred with eurocentric narratives and interpretations of events which is understandable due to the fact that it was written when African historiography was still at its early stages.
