Mekongga
Mekongga was a Tolaki kingdom around the Mekongga Mountains in southeastern Sulawesi. Tradition credited its founding to Sangia Larumbalangi; Sangia Melanga Mekongga ruled in 1337.
In 1676 the king’s brother Latoranga led construction of an earthen fort against coastal raiders. Under Bokeo Ladumaa, Mekongga adopted Islam in 1699 and asked Luwu for help teaching it. Ladumaa had aided Luwu against Suppa and received a red-and-white flag bearing the Islamic confession of faith.
