Modelled on a similar study of Rivers State in Nigeria, the objective of this study is to give a simple but authoritative interdisciplinary introductory history. Although written by specialists, it is directed to a lay readership. Bayelsa, being a new state, is in need of self- definition and understanding, not least to promote greater tolerance within and between communities. Thirty-six scholars, largely Nigerian, have contributed to the study, which is divided into seven parts: the enviroment, the people, culture, history, politics, economy and social services.
