Suria Angsa dari Banjar

Menurut George Bryan Souza (2004:126) dalam "The Survival of Empire: Portuguese Trade and Society in China and the South China Sea 1630-1754".
The ambitions of the Portuguese country traders involved in this market were greather than VOC firstimagined. The Company learnt that on account of an internal power struggle, Sultan Dipati Anom was challenged by his nephews, Sultan Ratu's two sons, Suria Angsa and Suria Negara, and Portuguese aid had been enlisted by the insurgents against Sultan Dipati Anom. The Portuguese from Macao were embarked upon their first attempt to establish their monopoly over Banjarmasin's pepper production.
