POWER 50 is fifty capsules across fifty days: the whole PSIR syllabus revised once, in the order the syllabus is actually built, one topic a day. The method is simple and it works only if you hold to it: read the capsule, write the same day, don’t break the chain. Running alongside are PSIR Dynamics 2026 and the PYQ Vault, which takes you through 560 previous-year questions over the fifty days, roughly eleven a day.
Day 36 — Regionalisation of World Politics
Today’s capsule sets out the whole of regionalism for fast recall. It begins with the meaning of regionalism as condition and process, and the idea of regions as “imagined communities” that cohere economically or culturally without always cohering politically. It then works through the theoretical traditions — Mitrany’s functionalism, Haas and the neo-functionalist spillover, the federalists, Deutsch’s communication approach and the intergovernmentalists — before tracing the evolution from nineteenth-century public unions to the European model. From there it covers new regionalism, the globalisation debate (building blocks or stumbling blocks?), the sovereignty question and global governance, and then the case studies in turn: the EU, ASEAN, APEC, SAARC, NAFTA and USMCA, BIMSTEC and Central America, closing on a comparative assessment. The ten-year record shows why this unit repays the effort: between 2016 and 2025 it carried fourteen questions across six themes, eleven at 15 marks and three at 10, with the EU and ASEAN taking most of them.
Write before the evening:
- Do you agree that the EU has thus far proved to be the most successful experiment in regional integration? Account for its successes and its recent challenges. (UPSC 2024, 15m)
- What were the limitations of NAFTA? How did its replacement by the USMCA counter them? Explain. (UPSC 2024, 15m)
- How successful has the ‘ASEAN Plus Three’ been in addressing regional problems? Support your answer with specific examples. (UPSC 2025, 15m)
If you go blank on a scholar or a debate, it is covered in full in the Foundation and OGP class notes and handouts. Revise that page, then write the answer.
