This book delves into the four main traditions that helped shape the contours of the Philippine security sector (its armed forces and national police): the Spanish colonial legacy, the Moro legacy, the Katipunan (revolutionary) legacy, and the American imperial legacy. In tracing the four historical nodes that forged and continue to inform the nature and ideology of contemporary Philippine military-police establishment, this book lays bare the socio-political, economic and religious forces that played into the national narrative of conquest and revolt.
