The concept of cultural heritage employs specific discourses, codes, values, and images that contain assumptions about a particular community and its members. Among the constitutive elements of a common heritage firmly stand language, history and territory. The contents of the cultural heritage are frequently socially, politically, culturally, and historically contested, which reveals competition among past, present, and future narratives that shape the existing national identities or lead to the creation of new ones. The paper examines the role of law in “defining” cultural heritage and “attributing” it to a particular community. In this respect the case of North Macedonia represents a unique case study on how international law embedded in the bilateral agreements with Bulgaria and Greece have shaped the past, present and future identity of that nation. It explores how the legal norms can shape the “attribution” of the cultural heritage by issuing legally binding interpretations of the historical events and personalities, usage of names and designations, and even the features of a language.
