Historical Treaties of Southeast Asia

A research program in global diplomatic history

Historical Treaties of Southeast Asia is a collaborative research program in Global Diplomatic History financed by the Swedish Research Council and running from 2022 until the end of 2027.

A team of seven researchers based in Europe and Southeast Asia investigate the role of treaties and treaty-making in the imperial expansion and colonisation of Southeast Asia from the eighteenth to the early and twentieth century.

The researchers systematically analyse all bilateral treaties concluded between a European, American or Japanese imperial power and a Southeast Asian polity between the eighteenth and early twentieth century. In addition, a selected number of diplomatic treaty-making processes are studied in detail. In doing so, the project aims to bring about a new and more nuanced understanding modern imperialism of relevance not only to Southeast Asia but globally.

The panel “Tools of Power in Global Diplomacy, 1400–1900” at the New Diplomatic History Conference in Aix—a conference presentation organized by Birgit Tremml-Werner—aims to discuss a new framework for studying the global development of inter-polity relations and negotiation patterns in the period between the fifteenth and the nineteenth century. Introducing three examples, one from the Middle East, one from South Asia, and one from Southeast Asia, the panelists will explore diplomatic norms, concepts, and practices including patronage, dynastic and community relations, and imperial institutions in search of comparisons and connections. Putting plural diplomatic norms and mechanisms in conversation with each other will nuance the story of systematized diplomatic relations as part of a linear development of one international system.

Birgit Tremml-Werner will present a paper entitled “Alliances and Negotiations in the Sulu Zone, c. 1760–1830”, which builds upon her collaborative work with Ariel Lopez and Eleonora Poggio.
