The Pacto de Sangre (Blood Compact), despite its crucial significance in Filipino conceptions of history, is seldom interrogated in Philippine historiography.

This article revisits the making of a founding myth of Filipino nationhood in light of scholarship on ancient blood oaths and the historical account of the encounter of Sikatuna and Legazpi.
