The Jus Post Bellum Project

From conflict termination to peacemaking:  Role and contours of a contemporary 'Jus Post Bellum'   

The concept of ‘jus post bellum’ has an established tradition in just war theory. It has long formed part of the ethics of warfare since scholastic writing and classical works on the law of nations. The problem of the ending of conflict and the need for a proper organisation of post-conflict peace has become evident in the context of recent interventions and their aftermath. In this context, jus post bellum has witnessed a renaissance in military ethics and moral philosophy. But it has traditionally been neglected in the conceptualization of the laws of war in the 19th and 20th century, which remains based on the classical division into jus ad bellum and jus in bello.
This NWO-funded Vidi project investigates whether and how a contemporary jus post bellum may facilitate greater fairness and sustainability in conflict termination and peacemaking.

Book on JPB from OUP

Jus Post Bellum Project staff have edited a new volume, published by Oxford University Press. The volume provides a comprehensive analysis of the laws and norms that apply to the process of ending war and building peace; systematically examines the merits and pitfalls of jus post bellum, drawing on theoretical inquiry, comparison to different bodies of international law, and key case-studies; and critically assesses the practical relevance of the theory of jus post bellum to the actual reality of post-conflict situations.

Jens Iverson, Researcher in International Law at The Jus Post Bellum Project, recently published an article on JPB, Transitional Justice, and International Criminal Law in the highly-ranked International Journal of Transitional Justice.


Conference Report

The Jus Post Bellum Launch Conference Report is available.

On 31 May and 1 June 2012, the Jus Post Bellum Project was proud to host its launch conference, “‘Jus-Post-Bellum’: Mapping the normative foundations.” The Conference Report focuses on the dialogue that occurred at the conference. It is impossible to capture the depth of the discussions that took place over the two-day conference, and therefore, as mentioned at the conference, we encourage participants and presenters to continue to debate on the project’s Virtual Research Environment. We are thankful to all participants and to attendees for sharing their insights.

Please visit the conference website for a wealth of material on Jus Post Bellum.
