NOTICE: Monica Garcia-Salmones Rovira joins the Interest Group History of International Law as a convenor

Message from Monica Garcia-Salmones to the members of the IG

Dear Friends of the blog of ESIL - IG of the History of International Law,

I am a trained international lawyer who embraced the turn to history in international law. I wrote my LLD in international law at the Erik Castrén Institute of International Law and Human Rights, (Helsinki University) with a thesis on the project of positivism in 20th century international law. After that, I held several post-doc positions, in projects such as ‘History of International Law: Between Empire and Religion’ and ‘The Concept of Natural Rights’, also based at The Erik Castrén Institute, where I was a Senior Researcher, and since 2016, an Associate Professor of International Law. Since 2023, I am Assistant Professor of Foundations of Law at the University of Maastricht, The Netherlands, and Co-Director of the Maastricht Centre for Law & Jurisprudence.

As an IG Convener, I would like to continue the great work done by the other Conveners so far. I am specially intrigued by the possibility of observing the past as a vast territory, which can be explored for thinking about the future. Creative ideas may arise from such observation. These ideas might or might not realise, but they can often contribute to enlighten our trouble times. I also would welcome the creation of opportunities to interact more with people focusing on doctrinal themes.

The other convenors welcome Monica and look forward to collaborating with her.

RECORDING: Hendrik SIMON in conversation with LAURI MÄLKSOO about "A Century of Anarchy? War, Normativity, and the Birth of Modern International Order" (OUP, 2024)

  

Source: OUP
Book discussion: A Century of Anarchy? War, Normativity, and the Birth of Modern International Order

The Interest Group on the History of International Law of the European Society of International Law (ESIL) organized an online discussion with Hendrik Simon (Frankfurt University / PRIF) and Lauri Mälksoo (University of Tartu) on Hendrik Simon’s recent book A Century of Anarchy? War, Normativity, and the Birth of Modern International Order (Oxford University Press, 2024).

The book challenges the conventional narrative that the nineteenth century was a period of unlimited warfare until the emergence of the League of Nations, the Kellogg-Briand Pact, and the UN Charter. Instead, Simon demonstrates how the concept of a “free right to go to war” (liberum ius ad bellum) was a construct of Imperial German legal realism, later universalized in international historiography. His work redefines our understanding of modern international order and the justifications of war. Hendrik Simon and Lauri Mälksoo will discuss the
book together, addressing current issues in the history of international law.

Speakers:
•       Hendrik Simon is Principal Investigator at the Research Institute Social Cohesion (RISC) at Frankfurt University and Senior Researcher at the Peace Research Institute Frankfurt (PRIF). His book A Century of
Anarchy? has received the Jost Delbrück Prize 2024 and the Helmuth James von Moltke Prize 2025.
•       Lauri Mälksoo is Professor of International Law at the University of Tartu, member of the Institut de Droit International, the Venice Commission of the Council of Europe, and the Estonian Academy of Sciences. He is co-editor of The Oxford Handbook of International Law in Europe (2024) and author of the forthcoming Russia, the Soviet Union, and Imperial Continuity in International Law (OUP).
