Most states have one or more ethnic minorities. Members of such groups invariably experience some degree of dissatisfaction with their status. In consequence, tension between subnational identity and national affiliation i s a persistent and pervasive reality. Although a large literature addresses the relationship between culture and nationality, it cannot be said that the interaction of minority-group aspirations and related government policies is well understood. In this article, we seek to build a foundation for such understanding through the development of a framework for comparative study. We propose a diagnostic formula that focuses o n minority-group demands ranging from recognition, access, and participation to separation, autonomy, and independence. We then consider the significance of geographical context and group-state interaction for minority goals. A more detailed analysis of circumstances that foster accommodation or conflict appears in nine case studies: Tamils in Sri Lanka, Druze in Lebanon, Old Order Amish in the US., Chinese in Thailand, Basques in Spain, Indians in Central America, Kurds in "Kurdistan," Sikhs in India, and Swedish-speakers in Finland. In the final section of the paper, we offer suggestions and speculations on the reasons for attainment or frustration of minority-group goals, the efficacy of related government policies, and research needs in the large and rapidly evolving field of cultural-political studies.
