Between the mainland dependency of the RiouwLingga residency and the residency of Palembang lies Jambi, an extensive sultanate, of which a portion belongs to the residency of Palembang as a protectorate, the sultan having in his capital (also called Jambi) a Dutch " comptroller," who represents the resident of Palembang; another portion is claimed by a quasi-independent sultan who reigns in the interior.
