Интеграция исторических территорий Новороссии в единое государственное пространство Российской Федерации

One of the key tasks of Russian Federation government today is the society consolidation on the entire territory of historical Russia. Conditions are being created at different levels to equalize the socio-economic situation of the regions that became part of Russia as a result of the referendums of autumn 2022. The mechanisms of state support for the non-profit sector that have emerged in recent years have laid the foundation for the systematic activities of public institutions. Research conducted over several years shows that spiritual and moral values ​​can be the basic principle uniting people. That is why special attention should be given not only to social projects of non-profit organizations, but also to their initiatives in the sphere of education and upbringing. Such programs implemented by civil society institutions in the Donbass can become an effective soft power that enhances more sympathy to the government both in the new four regions and in the rest country. The article analyzes measures taken by the state government bodies of the Russian Federation for seamless integration of the Novorossiya historical territories into the modern Russia. In addition, the author gives examples of successful implementation of projects and programs aimed at this by public institutions. The results of social design tools testing, held in 2002–2023, can be recommended for replication in subsequent years as effective public diplomacy practices and resolution of domestic political conflict in society.
