Sambaliung

Sambaliung lies beside the Kelay River, near its meeting with the Segah to form the Berau River in eastern Borneo. It became the seat of a sultanate that emerged from the division of the older Berau polity in the early nineteenth century. Sambaliung's territory included the Kelay basin and parts of the coast toward Tanjung Mangkalihat, linking its rulers to both the river interior and the sea.
