Buton
Buton was a kingdom on the island off southeastern Sulawesi. Local tradition holds that Wolio was founded around the fourteenth century, after which Queen Wa Kaa Kaa was elected.
The kingdom converted to Islam under King La Kilaponto, who became Sultan Murhum. Baubau was fortified in the sixteenth century, and under Sultan La Elangi between 1597 and 1631 the Murtabat Tujuh constitution took shape, providing for legislative, judicial and executive bodies. The sultanate later came under Dutch administration by treaty.
