Phase IFoundation

Background

Overview

Essential for understanding the legal and normative framework of international relations, India's foreign policy principles, and the debates surrounding state autonomy versus international responsibility.

Sovereignty is the supreme authority of a state over its territory and people, free from external control. The principle of non-interference dictates that no state has the right to intervene, directly or indirectly, in the internal or external affairs of another state. These are foundational principles of international law and the United Nations Charter.
