Islamic civilization has not been static and thus undergone a lot of changes since the birth of Prophet Muhammad (PBUH). Islamic civilisation has taken different trends, occasioned by specific events within the communities where Islam has been key in people’s lives. People need to understand these events as they have been unfolding and how they have impacted on the current organization as well as the social, economic, political and religious lifestyle of Moslems today, and their relationship with other non Muslims near and far from them. This book is presented in four chapters, consisting of; Life of the Prophet Muhammad, the Caliphate period, Muslim Empires (Umayyad, Abbasid and Fatimid Empires) and Muslim Organizations. This book has been majorly designed for use in both secondary schools, tertiary institutions and Universities, though lower academic classes can find it useful for some topics. The simple way in which the events and major issues in Islamic civilisation have been presented in this book, makes it an easy to read document by even lay people with keen interest in knowing the origins, development, present and future of the Islamic religion.
