Full title: VOC Glossary Indonesia

By The Corts Foundation, KITLV and ANRI, 2018


2015 DiplLetters bundle ENG cover

Reading and interpreting texts from the 17th and 18th century can be challenging because of the use of words and spelling that differs from modern Dutch. A glossary or list of terms can help reseachers to interpret centain words and to understand the origin of that word. The VOC archives in the National Archives of Indonesia (ANRI) contain numerous words that come from Dutch but also from the local asian region and other areas.

Mona Lohanda (senior archivist at ANRI) had made a first selection of terms from the VOC archives, especially from the marginalia of the Daily Journals of Batavia Castle. These terms are all described and translated into Dutch, Indonesian and English. The ethymology of these terms (the study of the linguistic origin) is researched by Dr. Tom Hoogenvorst of KITLV Leiden and this origin is added to the glossary. This makes the glossary as published here very much unique. 

This glossary results from the DASA project that has been conducted by TCF and ANRI for many years. All results are accessible on the Indonesian website and available for download, but also here (see below). 

The following persons have contributed to the realization of this glossay, with thanks:

  • Dr. Mona Lohanda, senior archivist ANRI
  • Dr. Tom Hoogervorst, Asian linguistic KITLV Leiden
  • Dhr. Marco Roling MA, information designer TCF
  • Ms. Nurhayu Santoso, indonesian translator

redevanternateFull title: The Theatrical Peace: Honour, Protocol and Diplomacy in the Balance of Power between the United East India Company and Ternate c. 1750

By Dr. Hendrik E. Niemeijer

(© H.E. Niemeijer, May 2012)


This paper deals with the relationship between the VOC government of Ternate (the northern Moluccan spice island) and the Sultan of Ternate in the 18th century. Formally this relationship was that between an overlord (the VOC) and his vassal, the Moluccan ruler. Although this problematic relationship was full of political manipulations and military threat of the local Fort Orange, there was also a political-cultural dimension in the reciprocal relations. In a specific local politico-cultural climate there was space for marks of honour, protocol, ritual exchange of gifts and ceremonial that contributed greatly to conflict prevention. The author argues that the local diplomatic ‘system of contact’, imbued with a feudal relationship, formed the foundation of eighteenth-century Dutch colonialism. The bulk of the gunpowder which John Company ever ignited in Fort Orange in the eighteenth century served no inimical purpose but was in the form of salutes for rulers who happened to sail by. Tea visits, appointment ceremonies, birthday parties in the Company garden all left room for cultural exchanges that promoted a ‘theatrical peace’.
