The Book on the NIALS Legal History of Nigeria was conceived after it became evident that a detailed chronological history of Nigeria was difficult to narrate in view of the antecedents of her people. Legal history is interested in how law and legal institutions operate and how they have changed over time in reaction to the dynamics of economic, social and political conditions in the country. The book therefore is the result of a meticulous work and research by selected intellectuals who are both in academics and practice of law and the topics discussed have been carefully selected to aggregate views on different aspect of Nigerian development.
