Kingdom of Bungku

The Kingdom of Bungku, also known as Tobunku or Tobungku, was an Islamic polity in present-day Central Sulawesi, Indonesia. It was located on the Southeast Peninsula of Sulawesi, in what is today Morowali Regency. Throughout most of its pre-colonial history, the polity was under a tributary relationship with the Sultanate of Ternate, with strong influence from Bugis merchants and the Bone State.

Bungku was a trading and raiding center on Sulawesi's eastern coast, exporting slaves, iron, inland produce, and sea cucumbers among others. Its economic fortunes declined following a series of conflicts in the mid-nineteenth century, and it was subsumed under the colonial administration of the Dutch East Indies in 1905. It remained as an autonomous subdivision of the Dutch East Indies, and later Indonesia, until its absorption into Poso Regency in 1961.
