On the occasion of the 50th anniversary of the end of the Eichmann trial, the Law Faculty of the University of Lisbon organized and hosted an international colloquium on the book »Eichmann in Jerusalem« that took place on April 27-28, 2011, in Lisbon. The main purpose was to evoke Hannah Arendt's oeuvre and to reflect upon the Eichmann trial. »Eichmann in Jerusalem: A Report on the Banality of Evil« is indeed an important keystone to understanding Arendt's work as a whole and constitutes a reference point in itself when addressing crucial problems in the fields of criminal law, international criminal law and philosophy of law. The main contributions, recollected for publication in the present English edition, give a rare opportunity for a kaleidoscopic and pluralistic series of views, made possible since her book gives an excellent lesson to experts in law and maintains an astonishing actuality. The present book covers aspects as broad and diverse as facing the evil; the legal and the political in Hannah Arendt; Eichmann in Jerusalem and Hannah Arendt's oeuvre; the Eichmann trial; reflections starting from Eichmann in Jerusalem; and finally, contemporary experiences of transitional justice.
