Philippine Muslim history (PMH), which is part of the Philippines' historical past, was subjected to minimalization and even exteriorization in Philippine literature as a consequence of Western colonization. Its importance was slowly recognized when the Muslims in the 1970s asserted their self-determination through armed struggle. This paper will examine the challenges PMH has gone through and see its potential as a tool in bridging religious and cultural gaps necessary for nation-building. It will also find out its relevance in rediscovering the Philippines' pre-Hispanic cultural heritage. Some of the ideas and arguments in this paper are derived from a roundtable discussion on the subject involving Filipino historians.
