Introduction
A major Shi‘i Muslim community, the Ismailis are currently scattered in more than twenty-five countries of Asia, Africa, the Middle East, Europe and North America. Ismaili historiography and the perceptions of the Ismailis by others, in both Muslim and Christian milieus, as well as stages in Ismaili studies have had their own fascinating evolution, of which we shall present a brief survey here; but first, a few facts about the Ismailis and their history.
