International Conference Explores Grotian Law and Modernity

In 1925, the third centenary of the first publication of Hugo Grotius' most seminal work on the law of nations, De jure belli ac pacis libri tres (Three Books on the Law of War and Peace) offered the occasion for elaborate festivities and commemorating activities in and outside the Netherlands. The anniversary was organized against the backdrop of a revival of interest in Grotius as a trailblazer for international law among proponents of the international 'peace through law' movement, which went back to the Hague Peace Conferences and was given new traction after the Great War.

In the past few decades, international academic interest has widened beyond the scope of international law to encompass the full extent of Grotius' life, thought and works across the disciplines. The mainstream narratives of Grotius as 'father of international law' and visionary defender of international peace and justice have given way to more nuanced readings of his life and work, as well as his many receptions and revivals, against the changing patterns of social, political and ethical ideas and values. In recent years, Grotius' role both as an actor in the Dutch imperialist enterprise and a defender of unity and reconciliation among the Christian confessions have been highlighted. All this solicits critical reconsiderations of De jure belli ac pacis and Grotius' role in the history of international law.

The major aim of the conference is to foster new narratives on the thought of Grotius, in general legal theory as well as in international law against a the backdrop of present-day rapid, fundamental changes that challenge the very foundations of the modernist paradigm, of which Grotius may be considered a key trailblazer. The core question of the academic conference is to what extent Grotian thought about general legal theory and international law is still relevant today, and what adaptations current foundational changes to our world make necessary. In this context, discussion of the many trajectories of reception, appropriation and reinterpretation of Grotius in different times and places, offers a valuable, additional perspective.

Through the conference 'Grotian law and modernity at the dawn of a new age', the organizers want to stimulate debate on the constitutional impact of current changes for the global legal order through the lens of a long-term historical analysis. The speakers in the conference are invited to reach back to Grotius' thought and work as a starting point for discussing the foundations of the modern legal order of the past four centuries and the changes this is currently undergoing. They are asked to use this long-term historical framework to make sense of current upheavals and look for direction towards the future of law.

The conference program falls into three parts (with parallel sessions).

Part I 'Lineages of Grotian thought' discusses the material and ideological receptions, reinterpretations and appropriations of De jure belli ac pacis at different times during the past four centuries. It assembles a number of papers that trace the lineages, in terms of material history or content, of Grotius' ideas with regards to different branches of legal theory or practical law. It looks to reviewing traditional, often celebratory narratives of Grotius from the late nineteenth and twentieth centuries from the perspective of a wide array of themes including political and economic governance, human rights, imperialism or (in)equality.

Part II 'Modernity and the dawn of a new age: general theory of law and governance' and Part III 'Modernity and the dawn of a new age: international law and governance' address the question of the significance of current changes for the constitution of a new global legal order, using De jure belli ac pacis as a platform for discussing the development, transformation and superseding of modern law.

Part II concerns general questions of the theory of law and governance.

Part III pertains to specific questions of public international law.

At the end of the second day, an academic session will be organized for a wider audience, with a key note speech and a panel discussion on the core topic of the conference.

Invitation to speakers

The organizers invite twelve speakers for each of the three thematic parts of the conference.

Part I 'Lineages of Grotian thought'

Convener: Mark Somos

Keynote speaker: Martine van Ittersum

The material conditions of the production and reception of De jure belli ac pacis form a neglected and highly rewarding field of research. Recent studies of the printing history of various editions have started to clarify Grotius' own role in the revision and timing of new editions; piracy and rivalry among publishers; the marketing strategy for each edition; and the dissemination and movement of copies. The burgeoning study of annotations that legal scholars, aristocrats, municipal and imperial administrators, prominent politicians and thinkers have left behind in their copies of De jure belli ac pacis is shedding new light on the hitherto unseen history of this work's real impact. Early insights into the lineages of Grotian thought that only close attention to the surviving copies' materiality can provide include the intensity and ingenuity of the Catholic reception of De jure belli ac pacis. Another set of discoveries that emerges from the material heritage of De jure belli ac pacis reveals historical moments of focused interest in specific passages of the text in response to crises that previous historiography has never considered to be part of the book's reception, such as the breakup of the Iberian Union, nineteenth-century abolitionism, or the start of World War I. Grounding the reception history of De jure belli ac pacis in the book's materiality is essential for recovering the four centuries of its impact in full, from its earliest classroom use to its latest invocation in front of an international tribunal, as well as for reassessing Grotius' role in the evolution of the laws of war, the relationship between morality and law, sovereignty, natural rights, freedom of navigation and imperialism.

Part I welcomes proposals for papers on the various editions' printing history, surviving annotations, evidence of the book's use in classrooms, in court and the corridors of power, and the broader relationship between the material and intellectual receptions of De jure belli ac pacis. We thereby expressly invite papers on receptions of and engagements with Grotius in different parts of the world.

Part II 'Modernity and the dawn of a new age: general theory of law and governance'

Convener: Marc de Wilde

Keynote speaker: Annabel Brett

In De jure belli ac pacis, Grotius developed three ideas that have been recognized as major innovations in legal theory. First of all, he presented natural law as the moral foundation of both domestic and international legal systems. Secondly, he revolutionized the traditional understanding of natural law by focusing on the natural rights of individuals. And thirdly, he distinguished between natural law and religious belief, arguing that the rights of individuals had to be protected irrespective of religious differences. With these ideas, Grotius stood at the cradle of the modernist paradigm of legal theory which emphasized the need for a secular and universal legal order based on individual rights. However, depending on the context in which Grotius's theory was applied, its meaning proved to be ambiguous. Thus, Grotius's concept of natural law was also used to justify imperialism and colonialism, and it served to legitimize the practice of slavery. Moreover, present-day challenges, such as climate change or the rise of artificial intelligence, require us to reconsider the main assumptions behind Grotius's theory, such as his notion of the free will or the unlimited availability of natural resources.

The speakers are invited to reflect critically on Grotius's contribution to legal theory and its present-day relevance by presenting papers on the following topics: the universality of natural law (or its limitations), individual rights as foundation of the legal system (and its potential downsides), the relation between natural law, imperialism and slavery, the challenges new technologies pose to the free will and legal regulation, and the state's role in balancing individual rights and the public good (as, for instance, in the case of climate change).

Part III 'Modernity and the dawn of a new age: international law and governance'

Convener: Eric De Brabandere

Keynote speaker: Hilary Charlesworth

This part pertains to specific questions of contemporary and future public international law. The actual text of De jure belli ac pacis libri tres is often neglected, given the wealth of secondary sources. This part of the conference invites critique and examination of the potential of De jure belli ac pacis as a text with contemporary relevance.

To this end, Part III invites papers that critically explore the Grotian traditions and its potential impact on particularized problems of contemporary international law. Of special interest are papers that adopt a critical lens to the Grotian legacy in the sphere of international humanitarian law and international criminal law. Critical analysis of the idea of a 'Grotian Moment' and the mainstream progress narrative of international law is invited. Analysis of Grotius' work on the treatment of foreigners and enemies (of all humankind or otherwise) is welcome, as are papers examining Grotian legacy in the context of jus post bellum (the transition from armed conflict to a just and sustainable peace). Ultimately, this section of the conference hopes to imagine how Grotius' great work could be used to better manage the problems of, if not the next 400 years, at least the next 40.
