Research on Radicalisation: Topics and Themes

Research on Radicalisation: Topics and Themes


The idea that terrorism comes in waves was first introduced by David C. Rapoport, the grand old man of terrorism research who started teaching about the subject half a century ago. He distinguished between four waves: the Anarchist Wave (1870-1920s), the Nationalist Wave (1920s-1960s), the New Left/Marxist Wave (from the 1960s to the 1980s), and the Religious Wave (from the late 1970s to today and beyond). Rapoport´s theory is one of the better theories in terrorism research, although it has not gone unchallenged.
