s it is today Zanzibar is composed of two small islands of Unguja and Pemba, each surrounded by few small islets, most of them not permanently resided. Despite its small area of about 1300 square mile in total, these island have attracting attention of the people all over the world. What was then the reasons for that? We can not answer this question properly unless we go back through centuries.
However we can neither neglect God’s favour by giving it splendid climate, keeping it at a very nice position in the Indian Ocean, about twenty five mile away from the gigantic mainland, formally known as Tanganyika, enjoying equinox weather. Nor can we forget contribution by many people of the world whom we are going to mention as the subject goes on.
Our knowledge of Zanzibar will therefore more or less depend on chronicles and tales of ancient geographers, travelers, traders and intellectual immigrants on one side and archaeological, anthropological, palaeontological and even geological researches done and those to be done. Some of these disciplines, if not all of them can spearhead the speed of revealing the hidden truth about Zanzibar.
Geology and palaeontology done in 1920s similarities and difference of non-living and living organisms between the two islands on one side and between them and near by and far land on the other. This is important to know before hand because human being is not living in an oblivion; to study him one has to study his environment, ecosystem that supports his life.
Archaeology and anthropology support and/or reject to what previous people have said by giving clear material evidence. In Zanzibar nine to ten researches have been conducted in these fifteen past years and many people have begun to understand Zanzibar history better and with longer span of time than they had been.
