Here is a guide for the general reader to the demi-monde of secretive political movements and terrorist groups that operate today in the shadow of Islam. Osama bin Laden and Al Qaeda are only the most visible of a complicated web of organizations inspired by particular radical interpretations of Islamic belief in their pursuit of a radical agenda for domestic change within their own countries as well as militant confrontation with the United States. With the help of maps, charts and diagrams, this handbook shows the location of these organizations around the world, and the linkages between them. Short essays introduce the key organizations, personalities and relationships, and the factors that underlie their rise to public importance. In Part Two, there are brief accounts of all the significant Islamist organizations, country by country, worldwide. And in Part Three, a who's who provides a directory of the known political leaders and prominent activists - their backgrounds, activities and current status.
