The article aims to find the constructive conceptual elements in the ideas of the anarchist theorist Peter Kropotkin which are suitable for resolving one of the fundamental contradictions of the modern world - the impossibility of an effective state-legal solution to many of the conflicts between states and their regions. This seemingly dead end conflict lies primarily in the internal contradiction of the original international legal document: the UN Charter. The article analyzes the views of Kropotkin on the problem of confrontation of communal and imperial beginnings throughout human history. Kropotkin’s ideas are noted for their potential productivity in the theoretical analysis and practical resolution of modern territorial conflicts on the basis of reforming international law. The concept of “regional sovereignty” is introduced into the terminological context.
