'In this extensive study, Anne Orford brilliantly traces international law's engagements with history across a century and more, weaving abstruse methodological disputes into an arresting narrative of political possibility foregone. What is history for? And how should it be practiced by those who manage the world's legal affairs? Anne Orford makes the case for doing things with history, for history as a political practice which can as well be apologetic as transformative. For Orford, international legal history is contested ground, an open field of political possibility and struggle. Everyone is here - the footnotes alone are worth the price! Her plea for an engaged and politically responsible history attuned to the ambiguities of the historical record is an invigorating challenge to everyone who dabbles - or dives deep - into the history of international law.'
