The article examines the ethno-national situation in contemporary Iran. The author, presenting a thesis on the existence of ideological and scientific approaches to the issue, analyzes the history, ethnic structure, anthropological and linguistic identity, and, most importantly, the political relationships among Iranian peoples, drawing relevant conclusions. The first section details the attempts by ideologists seeking to exploit the current ethno-national situation in Iran, showing the increasing attention of international and regional organizations, both large and small, from distant and neighboring countries, to national relations and the ethno-national situation in Iran, emphasizing their different approaches to this issue. The multinational nature of the Islamic Republic of Iran is also noted, as well as the fundamental constancy of the state’s national policy and the variations in its manifestations. In the subsequent presentation of the material, the article highlights the unique aspects of internal and external attitudes toward the national situation in Iran and emphasizes that the problem under study, according to specific parameters, is associated not only with internal but also with regional and, to some extent, global security. The article provides a relatively detailed analysis of the works of Iranian authors who adhere to an objective, scientific approach to all issues related to the ethno-national situation in the Islamic Republic of Iran. The study concludes that, alongside the long-standing dominant ideological approach aimed at denying the existence of ethnic structures and national relations, as well as justifying the state policy of creating a nation-state, in recent years, and on a limited scale, the formation of an objective and scientific approach has begun, emphasizing the existence of an ethnic structure, a crisis in national relations, and the need for reform in national policy. The article’s conclusions stress the necessity of adhering to the principles of international law in the area of human rights, including the collective rights of people (ethnic and religious minorities), as well as ensuring the implementation of the rights provided in the relevant articles of Iran’s constitution.
