This is motivated book. It is ambitious in that it tries, to make sense of the diverse ethnography in anthropology. My priorities, oversight and interpretations are bound to be contested, since there can be no single authoritative history of anything, least of all a sprawling, dynamic and disputed field like anthropology. The book is natural, since my aim throughout it has been to offer a moderate and balanced account of the historical growth of ethnographic anthropology as a discipline, not to propose a radical re-explanation of it. There exists a growing scholarly literature on the history of ethnographic anthropology, which this textbook does try to compete with. On the other hand, I know of no existing book which exactly the same scope as this one but there is different book in scope and significance. The scholarly literature is often particular to the a society I focused which is similar as existing textbooks on ethnographic anthropology which are more theoretically orientedor more committed to one or a few Indigenous traditions. The book my original works to look into the Somali Clan of Issa who lives in Federal Republic of Ethiopia.
