The issue of the nature of the state is one of the most important issues in political philosophy, and any interpretation of it will follow an interpretation of government ends, ideal government, and the necessity to obey the government, political legitimacy and freedom in its own way. The present study, which is theoretical in terms of its fundamental content, applies the theoretical framework of Mouffe's radical democracy, and focuses on one of the prominent figures of the political philosophy of public law in the 20th century, and finally attempted to answer the main question of what is the ideal government the type and the nature of it in the political theology of Karl Schmitt? The results illustrate that the understanding and interpretation of the nature of the state as well as the desired government in Schmitt's political philosophy and political theology in the light of understanding the fundamental concepts in his thought such as political theology is political matter, rule friend/enemy/independent dictatorship, sovereignty, the concept of exception in criticism of European liberal parliamentary system, negative anthropology, adaptation of citizenship to political nationality, criticism of the concept of majority in liberal democracy. The results also state that Schmidt's ideal government is compatible with the identity-oriented type of radical democracy. The significance of the study dates back to the growing criticism of liberal democracy and the emergence of radical democratic governments, especially in Latin America.
