What is "patusan"

Patusan is a fictional country originating in the novel Lord Jim by Joseph Conrad, published in 1900. It has subsequently appeared in various films and television shows.

In Conrad's novel, the country is a remote backwater in the South Seas, forgotten by the rest of the world and essentially without contact with outside civilization. Prior to Jim's arrival, it is ruled by various factions of native people, whom Conrad refers to as " Malays".
