HISTORICAL FOUNDATIONS OF THE INTERNATIONAL POLITICAL SYSTEM

3. Emergence of State Sovereignty

The concept of state sovereignty stands at the heart of modern international relations and political theory. It signifies the supreme authority of the state within its territory and its independence from external interference. Sovereignty defines not only the legitimacy of governments but also the structure of the international system itself. Yet, sovereignty is not an ancient or static idea—it is a historical construct that emerged through centuries of political transformation, warfare, and philosophical reflection.

The emergence of state sovereignty was shaped by the decline of medieval universalism, the religious and political conflicts of early modern Europe, and the gradual consolidation of centralized power. From its formative expression in the Treaty of Westphalia (1648) to its elaboration in modern political thought, sovereignty evolved as both a practical and theoretical response to disorder.
