Why were most ethnic minority organizations in interwar Poland permitted and sometimes encouraged by the state, when the ruling titular ethnic group pursued discriminatory policies against the same minority groups, faced hostility from these groups, and had the capacity to repress their organizations? Current literature focuses on repression as the main strategy deployed by states to manage these relationships. This article, on the other hand, asks why states allow minority organizations to operate. Using the logic of divide and rule, this article demonstrates that, in the case of multi-ethnic states, a state may prefer a plurality of organizations representing a certain minority ethnic group, particularly if the group is restive, in order to ensure that a united opposition cannot legitimately threaten the state’s political survival.
