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.

A session focusing on global diplomacy in the early modern world will take place at  Svenska historikermötet (Swedish historians' meeting) in Malmö, 6-8 May 2026.
 
Komplexa relationer: global diplomati i den tidigmoderna världen (Complex relations: global diplomacy in the early modern world).
 
The session, that will be held in Swedish, looks at how the expansion of European powers after 1500 contributed to the development of a diplomatic praxis on a global level, that included the conclusion of treaties and agreements as binding legal instruments. The panel seeks to catch the process by applying new perspectives on negotiations and treaty-making in the period up to the 19th century. Diplomatic history has traditionally focused on the political aspects of the contacts and usually retained a certain Eurocentrism. In later years, this has been challenged by new perspectives, often summarized as New Diplomatic History. Here, the researcher tries to analyse the cultural and ideological aspects in the diplomatic exchange. Aspects that are studied include gift exchange, personal relations, gender aspects, materiality. Interpreters, and different language versions of the treaties. Frpm these perspectives, the presenters strive to apply new interpretations in a number of cases from various parts of the world.

Treaties and Origins of the Cambodia-Thailand Border Dispute

Ever since Cambodia became independent in 1953, its border with Thailand has been contested, the ancient Hindu temple Preah Vihear (or Phra Wihan in Thai) being a particular source of discord. To understand the present conflict, it is necessary to look at two treaties concluded in 1904 and 1907.
