In his speech, Olexandr Skrypnyuk, Director of the V. M. Koretsky Institute of State and Law of the NAS of Ukraine, emphasized that territorial integrity is a key component of the constitutional system and one of the basic principles of the functioning of a democratic state. Violation of this principle in the context of Russian aggression leads to the understanding of mechanisms for protecting territorial integrity in the constitutional-legal and historical-legal aspects. Against the backdrop of the war, there is a need for a scientific understanding of the national legal doctrine, a consistent understanding of the unity of Ukrainian lands. The territorial integrity of Ukraine is not only an object of state sovereignty, but also of national identity, a holistic historical space. Under such conditions, one of the important tasks of domestic legal science is to understand and rethink the essence of the category of territorial integrity in the historical-legal and constitutional-legal context.
