Abstract: Ethno-nationalism, deeply rooted in the shared cultural, historical, and ethnic identities of a group, stands as a powerful force in global politics. This study delves into the interplay between history and culture in shaping ethno-nationalism, highlighting the roles of collective memory, cultural symbols, and historical narratives in its emergence. By examining case studies from diverse regions, it demonstrates how historical grievances and cultural pride have fueled ethno-nationalist movements. Furthermore, the research evaluates the broader impact of ethno-nationalism on contemporary political stability and intergroup dynamics
