Bücher von Jeffrey (University of Wisconsin Kaplan

Jeffrey Kaplan has been one of the most influential scholars of new religious movements, extremism and terrorism. His pioneering use of interpretive fieldwork among radical and violent subcultures opened up new fields of scholarship and vastly increased our understanding of the beliefs and activities of extremists.

Focuses on a small but important group of movements that constitute a distinct 'fifth wave' of modern terrorism, called the "New Tribalism". This book critiques David Rapoport's Four Waves theory, arguing that the theory does not account for movements which radicalize and turn inward, losing touch with, or interest in, their foreign compatriots.
