This volume brings together seventeen articles reflecting the wide range of scholarly interest in early Shi`ism over the past half century. All major branches of Shi`ism are covered. Some studies are historical in nature, whether dealing with specific events or offering a broad historical perspective. Others focus on literary issues, on the development of doctrine or on the relations between the Shi`a and the non-Shi`i world. The studies have been selected because they represent the best of current scholarship, or are classic works with continuing significance; six appear for the first time in English translation. The editor's introduction reviews the historiography of the field and highlights directions and trends in research and is followed by a bibliography of key further reading.
