Han Chan Piet was first appointed to the colonial bureaucracy when he was made his father's deputy in Surabaya, at an unknown date, with the title of
Luitenant der Chinezen. The Lieutenant succeeded his father on the latter's death in 1778 as both Kapitein der Chinezen of Surabaya and Pachter of the districts of Besuki and Panarukan. In 1796, the
Dutch East India Company further granted the Kapitein exclusive rights to the two districts for life. During the
French and British Interregnum (1806 – 1815),
Herman Willem Daendels,
Governor-General of the Dutch East Indies, decided to fill up state coffers by selling government land, including in 1810 the districts of Besuki and Panarukan. Kapitein Han Chan Piet bought both districts outright for 400,000 Spanish dollars, and was subsequently promoted by Daendels to the dignity of
Majoor der Chinezen. The new Majoor resigned his Chinese Captaincy of Surabaya in 1810, and took up residence in his districts as landlord. The traditional Javanese bureaucracy of the districts was maintained, but had to answer to their landlord. From 1794 until 1813, Raden Panderman, son of the Majoor's cousin
Adipati Soero Adinegoro, headed the Javanese bureaucracy of Besuki, first as
Ronggo, then from 1804 as
Tumanggung. French and British travellers during the Interregnum remarked upon the agricultural and economic development of the region under the Majoor's rule, but criticised his creation of a state within a state. At the same time, Majoor Han Chan Piet encountered difficulties raising enough funds to fulfil his financial obligations towards the colonial government. In 1813, his younger brother,
Han Kik Ko, Majoor der Chinezen, who had purchased the district of
Probolinggo and had ruled in an apparently despotic manner, was killed in a local revolt — dubbed
Kepruk Cina ('Attack on the Chinese'). The British government under
Sir Stamford Raffles, which had misgivings about Daendels' sale of government land, responded by repurchasing Probolinggo from the dead Majoor's heirs. Beset by financial difficulties, Majoor Han Chan Piet took this opportunity to sell back the districts of Besuki and Panarukan as well. ==Aftermath==
