Barito River
The founder of the sultanate, Raden Samudra, was of royal lineage of the Kingdom of Negara Daha. He escaped from the Kingdom of Daha to the Barito River area, because his safety was in danger, and established a new kingdom at Banjarmasin. With help from Mangkubumi Aria Taranggana, Raden Samudra converted to Islam on 24 September 1526, changing his name to Sultan Suriansyah. Banjar at first paid tribute to the Sultanate of Demak. That state met its demise in the mid-16th century, however, and Banjar was not required to send tribute to new power in Java, the Sultanate of Pajang.
