Location, extent, neighbours

Story hook

On the night of 15 August 1947, when Sir Cyril Radcliffe handed his pencil-drawn line to Lord Mountbatten, India inherited not just an independence but a geometry problem that has defined its strategic life ever since. The Radcliffe Line ran 3,323 km from the Rann of Kachchh to the foothills of the Himalayas. The McMahon Line (1914, Simla Convention) marked the eastern Himalayan frontier with Tibet. The Durand Line (1893) — drawn by a British civil servant in Kabul — fixed the western frontier with Afghanistan. Three lines, three centuries of cartography, and India today shares 15,106.7 km of land borders with seven countries and 7,516.6 km of coastline with nine maritime neighbours across the Indian Ocean.

The numbers matter. India is the 7th largest country by area at 3,287,263 sq km, the 2nd most populous, and yet sits at the dead centre of the Indian Ocean — equidistant from the Suez Canal and the Strait of Malacca. 2.4% of the world's land surface holds 17.5% of its people. This is not just geography; it is destiny weaponised.

The 2020 Galwan clash in eastern Ladakh, the 2025 Pahalgam attack and the resulting Indus Waters Treaty suspension, the Sir Creek dispute with Pakistan, and the Indo-Sri Lanka maritime boundary around Katchatheevu — every one of these flows from the simple geometric truth that India's location is also its predicament. This file walks through the four legal zones of Indian territory, the seven land neighbours, the nine maritime neighbours, and the maritime claims under UNCLOS.

Why this matters for UPSC

UPSC Prelims has asked location-extent questions in every year since 2014 — typically 1-2 questions on extremities, border states, neighbouring capitals, time zones, or maritime law. Mains GS-I asked direct strategic-location questions in 2017, 2019, 2022, and 2024 ("Discuss India's geographical advantages in the Indian Ocean Region"). This is also a foundation unit for IR (GS-II), strategic geography (GS-III), and the entire neighbourhood-first doctrine.
