In February 1623, a group of Dutch officials accused a team of English merchants and Japanese mercenaries of conspiring to capture a castle on Amboyna, a small island in what is now part of Indonesia. The island was central to the booming spice trade, which had fueled an increasingly acrimonious rivalry between the British and the Dutch. In a subsequent trial, Dutch officials extracted confessions from a number of Japanese soldiers (who had been employed by the Dutch East India Company to protect Dutch interests) and employees of the British East India Company, usually under the duress of torture, and sentenced them to death. What really happened at the trial and what can this incident tell us about imperial relations during the seventeenth century? This resource created by historian Adam Clulow of Monash University and the Roy Rosenzweig Center for History and New Media at George Mason University allows scholars and students to explore these questions and more via online exhibits, primary documents (e.g. paintings, legal documents, and letters), and a detailed timeline of events. There is also a teacher's guide for high school and university instructors interested in incorporating the Amboyna Conspiracy Trial into their classroom.
