Terrorism trials are an exceptional opportunity for better understanding and, hence, countering terrorism, since they are often the only place where most if not all of the actors of a terrorist incident meet again, and where the media report and broadcast their respective accounts. A nexus between terrorist violence, law enforcement and public opinion, terrorism trials showcase justice in progress and thus demonstrate to the world how terrorism suspects are treated under national law.This volume views terrorism trials as a form of theatre, where the "show" that a trial may offer can develop often disputable dynamics, which at times might inconvenience the government. Seeing terrorism trials as a stage where legal instruments are used (and abused) to argue the validity of contested political constructs, this study presents a performative perspective to draw attention to the mechanisms and effects of terrorism trials in and outside the courtroom. With special regard for how the power of these performances may in turn create new narratives of justice and/or injustice, it offers vital insights into terrorism trials directed against different types of terrorism suspects, from leftist to ethnic nationalist to jihadist terrorists, in Spain, Russia, Germany, the Netherlands, and the United States.Beatrice de Graaf holds a chair in the History of International Relations & Global Governance at Utrecht University.
