ABOUT THE FORUM
If one wonders about the comparative dearth of research on pre-twentieth-century historical studies on Mindanao, a number of paradoxes will provide an answer. To begin with, Mindanao has mostly been written by people from outside. To some degree, this is not surprising, given the legacy of the colonial past and its forms of bureaucratization and where the documents from and about Mindanao are stored today. But archival fragmentation and (unjust) colonial material legacies are not the only reason for limited historical scholarship from Mindanao. Truly and deeply studying the distant past is a luxury preserved to elites and wealthy states. This is more than a cruel postcolonial reality; it is also the reason why there are so few historical studies. For historians from outside, it is almost impossible to possess the necessary cultural and linguistic knowledge to appreciate the historical legacies ingrained in traditions, stories, and objects. Even written sources are often only partly accessible for researchers from outside. Mindanao-based researchers, in contrast, have physical, economic, or technical access limitations to their pasts. Making productive use of the linguistic and archival turns, the presenters in this forum will reflect on ways to empower future generations of historians to contribute to writing their local pasts into global narratives. To that end, they will introduce different types of archival sources and how to access and disseminate them.
