Existing studies on legal approaches to ethnic minority representation often highlight different systems’ strengths and weaknesses. While this scholarship provides important insights into the growing body of literature on minority representation, the topic remains largely under-theorized. Because systems of ethnic minority representation clarify the organizations and philosophies of diverse states, more theoretical analyses can enrich the descriptive literature. Building on the existing scholarship, this article assesses Romania’s particular version of proportional representation regarding designated national minorities. It applies two theoretical models: (1) institutional activism and (2) ethnic intermediation. The former clarifies the establishment of Romania’s post-communist constitutional provisions regarding minority organizations, and the latter explains how small yet influential minority populations make claims to and reallocate resources from the Romanian state. Through a unique, understudied case study – the Armenian community of Romania – this article attempts to broaden ethnic minority representation scholarship by refining the theoretical frameworks of institutional activism and ethnic intermediation.
