Kangchu System

The Kangchu system was a socio-economic system of organization and administration developed by Chinese agricultural settlers in Johor during the 19th century. The settlers organized themselves into informal associations (similar to the Kongsi organizations found in other Chinese communities), and chose a leader from among themselves. In Chinese, "Kangchu" (Chinese: 港主, Pinyin: Gáng Zhǔ, Teochew: Kaang6 Zhu8) literally means ‘lord of the river’, and was the title given to the Chinese headmen of these river settlements. The "Kangchu" leaders are also called "Kapitan".

The term "Kangchu" became widely used during the 19th century, as Chinese immigrants began to settle in and around Johor state and set up gambier and pepper plantations. The social and economic welfare of the early Chinese settlers came under the charge of local Chinese leaders, who were responsible for running these agricultural plantations, which were situated along the river banks.

The Kangchu system traces its origins from the 18th century when Chinese coolies settled in Penang and Riau and set up gambier and pepper plantations there. The sovereign rulers of Johor, Temenggong Ibrahim and his successor, Sultan Abu Bakar, took up the Kangchu system during the first half of the 19th century to provide a more organised form of administration as Chinese immigrants began to settle in the state in great numbers and developed the state's agricultural economy. Variants of the Kangchu system also thrived in other parts of the Malay Archipelago, where gambier and pepper were extensively cultivated and where there were significant Chinese populations. The Kangchu and coolies who worked in the gambier and pepper plantations were mainly of Teochew origin, and were generally first- or second-generation Chinese immigrants. In 1917, the British colonial government in Johor implemented an act which abolished the Kangchu system in the state, and the value for gambier declined during the early 20th century.
