What is Shi'i Islam?

For the public at large Shi’ism often implies a host of confused representations, suggesting more often than not obscurantism, intolerance, political violence and other ignominies running hot or cold in response to world events. In fact for many people, Shi’ism stands for "radical Islam", or – worse – "Islamic terrorism". In some respects, nothing is more familiar than Shi’ism, and yet nothing is more misunderstood. For some twenty years the media have increased their coverage of the phenomenon.
