The War on Terrorism and the Decline of Terrorist Group Formation: A Research Note

Over the course of the twentieth century, terrorist organizations possessing different political and religious outlooks have been formed in different regions of the world. This note reports that the peak decades for the formation of terrorist groups were the 1970s and 1980s. Since that period, the pace of terrorist group formation has slowed substantially. Further, during the 1970s and 1980s the political goals of terrorist bands consisted of a heterogeneous mix of nationalist, left-wing revolutionary, right-wing radical and religious agendas. During the 1990s new terrorist groups have been largely reflective of religious concerns, Islamist ones in particular.
