Postcolonial approaches to the Middle Ages have received much attention in recent decades, and the study of medieval processes of collective identity formation and medieval nationhood have likewise been increasingly influential. 'Other Nations' participates in this discourse, but its goal is to trace the complex processes of mythologizing (and hybridizing) identities in the British Isles throughout the Middle Ages, specifically how the hybridizing of the mythologies informs processes of collective identity formation. The authors in 'Other Nations' address the question of hybridization from different vantage points, including those that indicate a resistance to assimilation, as way of emphasizing that the process of identity formation does not follow a universal formula and must be considered on a case-by-case basis. Thus, 'Other Nations' gestures towards a narrative of the transformations of Insular hybridity over the course of the Middle Ages into the early modern period. Contributors: Susan Carter, Robert R.
