About Political Science & International Relations
Subject Overview
PSIR (Political Science & International Relations) is one of the most opted UPSC optional subjects, comprising two papers: Political Theory and Thought (Paper I) and Comparative Politics and International Relations (Paper II). The syllabus covers Western and Indian political thinkers, comparative government systems, international relations theories, and India's foreign policy. Candidates who enjoy conceptual analysis, contemporary affairs, and structured argumentation find PSIR a natural fit. The subject rewards clarity of thought, precise terminology, and the ability to link theoretical concepts with current events.
Why Political Science & International Relations Is Popular
PSIR consistently ranks among the top optional subjects by candidate preference. Its popularity stems from significant overlap with General Studies papers — especially GS II (Polity, Governance, International Relations) and GS IV (Ethics). This overlap reduces the total preparation burden. The answer-writing style for PSIR closely mirrors GS demands, making it easier to practice both simultaneously. Additionally, the syllabus is well-defined, predictable, and supported by abundant study material including standard textbooks, coaching notes, and previous year question banks.
