Political Science and International Relations (PSIR) is one of the most popular optional subjects in the UPSC Mains exam because it overlaps heavily with General Studies, Essay, current affairs, governance, international relations, and ethics. Unlike many technical optionals, PSIR allows you to connect theory with real-world political developments, global events, constitutional debates, diplomacy, and social movements.
The UPSC PSIR Optional syllabus is divided into two papers. Paper I focuses on Political Theory and Indian Politics, while Paper II covers Comparative Politics and International Relations. Since many topics remain relevant in newspapers and current affairs discussions, preparation often becomes more engaging and dynamic.
UPSC PSIR Optional Paper I focuses on Political Theory, Indian Political Thought, Western Political Thought, Indian Constitution, governance, democracy, federalism, political ideologies, and social movements. The paper builds conceptual understanding while also linking political ideas with contemporary Indian politics and constitutional developments.
