Banggai
Banggai was an island kingdom off eastern Celebes, centered on Banggai Island. It followed local beliefs in 1337; a Chinese document of 1304 and a Majapahit poem named it as a Majapahit tributary.
In 1564 Banggai's king sent his son to Ternate to compare Christianity and Islam, choosing Christianity. Sultan Babullah of Ternate conquered the islands' states; in the 1580s his general Adi Cokro expanded into Celebes. After the 1667 Treaty of Bongaya, Ternate took tribute and appointed rajas. Raids and wars drove the court from Banggai to Mendono in 1690 and to Balantak in 1708.
