This book serves as a valuable contribution to the understanding of the meaning, practice and history of tourism in Tanzania, Africa and the world at large. It attempts to critically answer three questions: what is tourism? What are the approaches underpinning its practices? How did it evolve to become one of the largest sectors of commerce in Tanzania, Africa and the world? The book brings together information that is dispersed in various sources such as books, journals and reports within the tourism field and from other related disciplines. Some of the information is based on the author’s own experience and observations thus, further enriching the book. The interesting and welcome features of the book are that the author brings to light the contribution of Africa and Africans to the history of tourism. He also attempts to critically examine the information he has collected from different sources and to draw conclusions. The reader may disagree with a given conclusion and, thereby, be indirectly challenged to seek further information to confirm or invalidate the conclusion. In this way, the book encourages the reader to search widely for information on a subject of interest and, consequently, to learn more about the subject. The book is useful to all tourism stakeholders; in particular, students, trainers, practitioners, academicians, researchers, tourism entrepreneurs and the public at large.
