As in all religions' early histories, the difference between myth and fact is often difficult to detect. But what may be a problem for the fact-based historian is not a problem, and may well be an advantage, to the believer, whose tenets rest on a rigidly convincing narrative--in Twelvers' case, of supreme martyrdom and victimology, usually at the hands of Sunnis, as reflected by the bloody fate of virtually every one of the Twelvers' founding imams.
