T his article examines fractures in the social representations of a contested peace agreement in the longstanding territorial conflict of Mindanao. We compared representational structures and discourses about the peace talks among Muslims and Christians. Study One used an open-ended survey of 420 Christians and Muslims from two Mindanao cities identified with different Islamised tribes, and employed the hierarchical evocation method to provide representational structures of the peace agreement. Study Two contrasted discourses about the Memorandum of Agreement between two Muslim liberation fronts identified with separate Islamised tribes in Mindanao. Findings show unified Christians' social representations about the peace agreement. However, Muslims' social representations diverge along the faultlines of the Islamised ethnic groups. Findings are examined in the light of ethnopolitical divides that emerge among apparently united nonmigrant groups, as peace agreements address territorial solutions. Research results are likewise discussed in relation to other tribally contoured social landscapes that carry hidden, yet fractured ethnic narratives embedded in a larger war storyline.Keywords: Mindanao, territorial conflict, ethnic identities, peace talks, social representations, hierarchical evocation methodThe southern island of Mindanao in the Philippines has been the politico-military arena of a longstanding territorial conflict (Bertrand, 2000;Buendia, 2005) often described as a Muslim-Christian clash (Milligan, 2001;Tan, 2000). However, Mindanao is not only the Philippine hotbed of territorial conflict, it is also a region in which several peace initiatives have taken place. authority over these defined territories. The public announcement of the MOA triggered a series of peaceful and armed protests among Christians, and counter-protests among Moro-associated forces. The Supreme Court eventually junked the peace agreement, and the Philippine president fired the government peace panel that she herself had constituted.This recent peace fiasco likewise called attention to divisions among Muslims. With this recent unsuccessful attempt to establish peace in Mindanao, we investigated the nature of the psychological fractures within the Muslim front. We looked at how different Islamised groups in Mindanao made sense of the Memorandum of Agreement. However, as social psychologists who are Christians, we reflexively acknowledge our perceptive limitations as we attempted to understand political meanings held by two different Islamised tribes in what has been labelled a Muslim-Christian conflict. We viewed our research question through the lens of social representations theory, because this theory lends itself well to illuminating the subjective landscape of social conflict.
