How was the national sovereignty established?

Answer 1

National sovereignty was established through a historical evolution marked by the Treaty of Westphalia in 1648, which ended the Thirty Years' War and laid the groundwork for the modern state system. This treaty recognized the principle of territorial integrity and the right of states to govern themselves without external interference. Over time, the concept was further solidified by the emergence of nation-states and the development of international law, emphasizing the importance of self-determination and political independence. As a result, national sovereignty became a fundamental principle in international relations, guiding interactions between states.
