Death to Order is an analytical history of assassination between 1914 and 2024, one-hundred-and-ten years.Death to Order sets out to convince the reader, with a mass of archival evidence drawn from around the world, that modern assassination (i.e., since 1914) has been, and is, fundamentally a phenomenon related to states. That is not to say that states were always behind assassination – although they sometimes were – but rather that the reaction of states, and particularly great powers, to assassination has given modern political murder its potent charge.Secondly, Death to Order shows that the changes assassination wrought in democracies were subtle but identifiable in the archives. One must always acknowledge that available evidence on assassination is both complex and fractured and needs to be unravelled with care; however, this can be done by the application of proper historical research.
