Datu Piang

[1] He was one of the most powerful rulers in Maguindanao from the end of Spanish rule to the arrival of American forces in late 1899.

This apparent blunder by Datu Uto helped Piang gain a large following in the Buayan mainland, which eventually culminated into his usurpation of power.

On the 6th day of the same month, Piang overthrew the Spanish garrison in Cotabato and Tamontaka and granted himself the title of 'Sultan of Mindanao'.

However, in spite of this, the Moro resistance would be organized by Datu Ali of Buayan, but would be fully suppressed by American expeditionary forces in 1905.

With Datu Ali gone, Piang has lost any potential local rival that could threaten his authority and would continue to collaborate with the American civil government.
