List of kongsi
The kongsi federations of West Borneo were Chinese autonomous entities that conducted the mining of gold, and later expanded to other fields of business, based mainly in the Monterado and Mandor areas. The region never unified into one kongsi federation, and rather was a conglomeration of small kongsi organizations that mainly pledged to two zongting (assembly halls): the Heshun Confederation and Lanfang Republic in Montrado and Mandor, respectively.
