The elite of the kingdom accepted Islam in 1605, and strove to disseminate the creed in different directions in the Indonesian Archipelago.
During this period Makassarese power encompassed most of Sulawesi, East Kalimantan, Lombok, Sumbawa, and some parts of Maluku and Timor.
The ensuing Treaty of Bongaya regulated political affairs in the region, and ensured the presence of the Dutch in South Sulawesi.
In the following decades several Tallo princes led restless lives as overseas sea migrants, often turning to piracy and raiding.
The Tallo homeland existed as a separate state under Dutch suzerainty until 1856 when the 23rd and last king, La Makkarumpa Daeng Parani, had to step down.
