The article considers the existing approaches in the modern social sciences to the definition of "protectorate". Based on their analysis, it is concluded that the definition of "protectorate" has a multifaceted interpretation. The aim of the work is theoretical and legal analysis of the protectorate, identification of its features and forms. Depending on the subjective composition, a monistic and dualistic interpretation of the term "protectorate" is proposed. The author's version of the concept of "protectorate" is presented as a certain form of semi-colonial, client statehood, which provides for the dependence of one state on another in the field of interstate relations and is characterized by the fact of patronage of a stronger state over a weaker one. The main features of the protectorate are highlighted. It is emphasized that the practical implementation of the clash of civilizational interests of world leaders seeking to form their own geopolitical clusters of influence, creates conditions for a new life of forms of interstate relations that have become classics, namely forms of client statehood,forcing other states. interests, "of their own free will" to give part of their rights and powers, provided they are supported. We are talking about such forms as: associated state, satellite state, puppet state, neo-colony and protectorate. Similar to each other, united by one essential feature: the presence of limited power, these forms require careful analysis. It is worth noting that the terminology of the definition of these forms has been the subject of research by political scientists, philologists and historians, and requires additional state and legal interpretation. The concept of protectorate today does not have a single established interpretation and is used in many variations. Among them, taking into account the above topics, it is worth paying attention to the monistic and dualistic approaches to understanding the protectorate, when the determining criterion for such a distribution will be the quantitative subjective composition. The dualistic approach is more common and assumes the following variations, but they all involve at least two subjects of interstate relations: the protecting state, which exercises power, and the protected state, over which such influence is exercised. Understanding the protectorate in its monistic sense is perceived as a form of temporary sole power, a person (protector) who governs a state with a monarchical form of government until a certain time or in the presence of other special circumstances that make it impossible to exercise power by a monarch. Based on the above, we can determine that the protectorate is a form of semi-colonial, client statehood, which provides for the dependence of one state on another in interstate relations and is characterized by the presence of a stronger state over a weaker (dualistic understanding) or atypical form of monarchy (monistic understanding).
