corpusdiplomaticumThe Corpus Diplomaticum Neerlando-Indicum comprises six volumes, and was published between 1907 and 1955 by Mr J.E. Heeres and Dr F.W. Stapel at the Koninklijk Instituut voor Taal-, Land- en Volkenkunde (KITLV). These volumes contain a representative collection of political contracts and treaties concluded by the Dutch in Asia and permits granted to them.


For the first time these volumes have been scanned and published online by The Corts Foundation together with a searchable database of all the 1193 contracts and indexes on persons and places. Each volume separately has such indexes, but all the indexes are now combined together to give full access to all six volumes. Thousands of persons and places are named in these indexes and together form a valuable source for historians and other researchers. 

All the scans, database and indexes can be accessed on the Indonesian website of sejarah-nusantara.

The open data of this publication can be downloaded from the DASA project page.

UPDATE November 2019:

The six volumes are republished on this website by The Corts Foundation in PDF format including OCR text recognition. In this way the Corpus Diplomaticum is fully text searchable and the volumes are also freely available as download.

Bronbeek, 28 February 2019. The yearly commemoration of the battle of the Java Sea 1942 with the laying of a wreath was held today in the presence of the Marine Corps. Before the actual commemoration ceremony, dr. W.G.J. Remmelink presented his speech on the battle, illustrated with maps, and explained in detail the operational sequence of events and the ship movements. His presentation was based on his translation of Japanese source material from the Senshi Sōsho volume 26. 




February 13th, The Corts Foundation presented her latest publication called “The Diplomatic Correspondence between the Kingdom of Siam and the Castle of Batavia during the 17th and 18th century” (translated in the Thai language) to the Ambassador of the Kingdom of Thailand Mrs. Eksiri Pintaruchi.

We are grateful to our partners of the Chulalongkorn University in Bangkok: Mrs. Prof. dr. Bhawan Ruangsilp, dr. Dhiravat Na Pombejra PhD and Miss Joyce Sutthiman Limpanusorn.

By translating original Dutch correspondence into English, Indonesian and now Thai, this unique correspondence becomes more accessible to historians worldwide, and especially also now in Thailand.
