Hugo Grotius (1583-1645) is generally regarded as one of the ‘founding fathers of modern international law.’ However, he was also one of the early architects of Dutch colonial and imperial rule in the East Indies. Between 1604 and 1615, he served the Dutch East India Company (VOC) as a legal advisor and political lobbyist. In this capacity, he wrote memoranda and policy documents providing legal and political justifications for the Company’s commercial and military activities in monsoon Asia. In 1604, Grotius was commissioned by the VOC to write a treatise to defend the seizure of a Portuguese vessel off the coast of Johor (present-day Singapore). In the only published chapter of the treatise during his lifetime, titled The Free Sea (Mare Liberum), he argued that the Portuguese violated the natural rights of the Dutch by preventing them from sailing to the East Indies and engaging in trade with indigenous populations. As judicial recourse was lacking, even a private trading company such as the VOC could wage a ‘just war’ to enforce its natural rights. Grotian thinking about natural law, contracts and just war thus legitimized Dutch expansion overseas and the dispossession of the native.
Grotius’ On the Law of War and Peace is another case in point. Although the author was an exile in Paris by then, he relied on many years of practical experience as a VOC advisor and lobbyist in writing his magnum opus. In On the Law of War and Peace, he elaborates the views presented in On the Law of Prize and Booty by conceptualizing the natural rights to travel and free passage, the rights to settle in uninhabited lands and use natural resources, and the right to free trade between ‘persons at a distance’, invoked by Europeans to demand access to non-European markets and territories. On the Law of War and Peace also provides a legal justification of slavery as part of natural law and the law of nations. In the author’s view, those who are defeated in a just war can be enslaved under the law of nations, while human beings may also ‘voluntarily’ submit to slavery under natural law. Moreover, the children of the enslaved inherit the unfree status of their parents according to On the Law of War and Peace.

The aim of this workshop is to explore the many connections between Grotius’ thinking about natural law and the law of nations and his full-throated defense of European expansion overseas and slavery. We invite contributors to critically examine these connections by addressing the imperialist and colonialist readings of Grotius’ theory of natural rights, just war, property, unequal treaties and alliances, monopoly contracts, slavery, and the role of private actors (e.g., trading companies). We specifically welcome contributions that engage with the following questions:

• What were non-European responses to, or engagement with, such imperialist and
colonialist readings? For instance, how did East-Indian rulers receive and interpret,
or indeed resist, Grotian conceptualizations of natural rights and (monopoly)
contracts? Were alternative conceptualizations proposed to contest Grotius’
justification of slavery?

• What was the relationship between the ‘Grotian tradition of international law’ and
colonial practices in the early modern and modern eras? How were Grotian
discourses of international law used to justify colonial warfare, native dispossession
and slavery in the Americas, Asia and Africa between the 17th and 20th centuries?
For instance, how did Grotian ideas about natural law, freedom of trade and
humanitarianism (protecting the oppressed from inhumane treatment) contribute to
justifying colonial warfare, and what role did private trading companies play in
these wars?

In addressing questions like these, we seek to understand the ambivalent relation between, on the one hand, Grotius’ innovate contributions to international law and humanitarianism, and, on the other hand, the use of his concepts to justify (Western) colonialism and imperialism.

Conditions
A paper proposal of max. 300 words should be sent to j.giltaij@uva.nl and m.dewilde@uva.nl. The deadline for submissions is January 15th, 2024. Applicants will be notified by February 26th, 2024 whether their paper proposal has been accepted or not. The organizing committee will use two criteria in the selection of paper proposals: intellectual quality and potential fit with the workshop theme. The workshop is meant to be interdisciplinary and small-scale, allowing plenty of time for discussion and interaction. Available slots are limited. However, the committee’s aim is to invite speakers from diverse backgrounds (age, geography, gender, and career status).
The workshop takes place on location. Speakers who are unable to participate in person
may do so online. Unfortunately, the organizing committee is not able to cover the costs of accommodation or travel. Selected speakers are requested to obtain funding themselves. Each speaker will be given a 30-minutes time slot, which includes 20 minutes for presentation and 10 minutes for questions and discussion. Our aim is to publish (revised versions of) the presented papers in a leading international journal related to Grotius, the history of international law, or the history of colonialism.
