Out of the over fifty odd tribes that the Philippines nurtures, merely five were inclined toward the practice of headhunting. These are the Ilongots, Kalingas, Ifugaos, Igorots and Tinguians - in that order of importance, propensity and aggressiveness. Each tribe had a particular brand of motivation, which we examine in this book. Let it, however, be impressed that vendetta was the classic motivation behind all headhunting practices, whether Ilongot, Kalinga, Ifugao, Igorot or Tinguian. This is decided through ritual, vengeance councils, fearlessness and other factors. Still, a tribesman's death cannot go unavenged. By all means, it must be repaid... with nothing short of human life.
