Johannes Siberg (1740–1817) was Governor-General of the Dutch East Indies from 1801 to 1805, during which time control of the Dutch Indies passed from the Dutch East India Company (VOC) to the Napoleonic Dutch State in the guise of the Batavian Republic (later superseded by the Kingdom of Holland) which took over much of Dutch territory and broke their monopoly of trade. Local kings and princes took the opportunity of troubled times to try to reassert themselves. The various governments in the homeland tried various means to retrieve matters, including troop reinforcements and reforms, finally formally taking over the government functions of the VOC. Siberg resisted many of the reforms, and continued to do so after being removed from office.
