The book, “The Rulers of Magindanao in Modern History, 1515–1903: Continuity and Change in a Traditional Realm in the Southern Philippines” by Datu Michael Ong Mastura has been published by the Ateneo de Manila University Press. It covers the events starting from the arrival of Sharif Mohammad Kabungsuwan in 1515 and ends with the establishment of the Moro Province by American colonizers in 1903. The author is a Moro scholar, educator, lawyer, lawmaker, and peace negotiator who is currently serving as the President of the Sultan Kudarat Islamic Academy. The book is a welcome addition to the growing literature on Mindanao and is essential in any attempt to write and teach a history of the island and its diverse peoples.
