Johannes Siberg 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 to the NapoleonicDutch State in the guise of the Batavian Republic 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.
Early career
Johannes Siberg born on 14 October 1740 in Rotterdam. When he was 18 years old, he left for the Indies as a contabelsmaat. He soon gave up the sea and climbed expertly through the Company's ranks - Underbuyer in 1770, Buyer in 1771, to reach Senior Buyer in 1776. He married the daughter of Willem Arnold Alting and shortly after that left for Panang to be the governor of Sumatra's West Coast. In 1780, he became Governor and Director of Java's Northwest Coast. He occupied this extremely lucrative post for seven years and became enormously wealthy. Meanwhile, in 1782 he became Counsellor-extraordinary in the Dutch Council of the Indies. After returning to Batavia, in 1787, he became President of the Schepenbank, as well as a colonel in the localmilitia. In 1791, he was appointed full Counsellor of the Indies ; in 1793 he was First Counsellor and Director-General. At the same time his father-in-law managed to get him appointed one of the three Commissies-generaal. This duo managed to concentrate a lot of power in their hands, and those of their wider family attachments, especially after the new Batavian Republic merged the Commissie-generaal with the Raad van Indië. In 1800, the Batavian Republic took over formal control of the government of Nederlands-Indië and vested authority in Council for the Asian Possessions, whose combined assembly was packed with family members. They acted as a brake on much needed reforms, and lost ground to the British in particular.
In 1801, following the death of his predecessor, Pieter Gerardus van Overstraten, he became acting Governor-General, and, one year later, was confirmed in the full, official function by the Batavian Republic. In 1802, the Peace of Amiens also ended the Dutch trading monopoly, and they came under increasing British pressure. Following accusations of corruption and financial bungling, he was removed from office in 1805. In 1806, the Kingdom of Holland replaced the Batavian Republic. The new Kingdom established a Ministry of the Colonies to deal with Indian affairs. The new Governor-General Albertus Henricus Wiese was charged with making much needed reforms. Siberg, however, remained in the Indies, as leader of the Oudgastenpartij, a group of conservative landowners and merchants, still influencing his successors' attempts at reforms. He died in Batavia on 18 June 1817.
