Political geography and geopolitics

Detail

1. Political geography: what it studies

• Political geography is the branch of human geography that studies how political power is spread over space. Its sister subject is political science.
• NCERT (Class 12, Table 1.2) lists political geography with two sub-fields:

Field of human geography	Sub-field	Sister discipline in social science
Political geography	—	Political science
	Electoral geography	Psephology
	Military geography	Military science

• What it covers (NCERT, Class 11):
• Boundaries: the lines that divide one state or unit from another.
• Space relations between neighbouring political units: how countries or states next to each other deal with each other across space (trade, disputes, rivers they share).
• Delimitation of constituencies: drawing the borders of voting areas.
• Election scenarios: how voting is spread over an area.
• Political behaviour: why people in different places vote or act politically in different ways.

2. Electoral geography

• Electoral geography studies elections over space: where people vote, how they vote, and how voting areas are drawn. Its sister discipline is psephology, the study of elections and voting. The word comes from Greek psephos, the pebble the ancient Greeks used to cast a vote.
• Voting patterns: maps of party support, turnout and swing show regional strongholds, for example urban–rural or coastal–interior differences.
• Delimitation: fixing the boundaries of territorial constituencies (voting areas) for elections.
• Article 82: Parliament passes a Delimitation Act after every census. The Central Government then sets up a Delimitation Commission [5].
• Delimitation Act, 2002: it readjusts how Lok Sabha seats are shared among states. It also fixes the total seats in each state Assembly and divides each state into territorial constituencies [4].
• Geographical rules in the 2002 Act [4]:
  • Every constituency must be a geographically compact area.
  • The Commission must keep in mind physical features, existing administrative boundaries, means of communication and public convenience.
  • Every Assembly constituency must lie wholly within one Parliamentary constituency.
  • Seats reserved for SCs and STs must be spread out sensibly.
• Census base: today's constituencies were drawn on Census 2001 figures [4][5][6].
• Freeze: a 2002 constitutional amendment stopped any new delimitation until the first census after 2026. The present constituencies stay in force until then [5][6].
• Numbers: there are 543 Parliamentary constituencies. Of these, 84 are reserved for SCs and 47 for STs (ECI) [5].

• For the Delimitation Commission's powers and composition, see the polity subject.

• Gerrymandering: drawing constituency boundaries on purpose so that one party gains.

• Origin: in 1812, Governor Elbridge Gerry of Massachusetts (USA) signed a law that redrew state senate districts in favour of his Democratic-Republican party [7].
• One district had such an odd shape that the painter Gilbert Stuart drew a head, wings and claws on it and called it a salamander. An editor replied, "Better say Gerrymander" [7].
• Why it works: if you pack the other party's voters into a few seats, or spread them thinly across many seats, they win fewer seats than their share of the vote.
• How compactness rules help: rules like the "geographically compact area" clause of the 2002 Act make such odd shapes harder to draw [4].

3. Military geography

• Military geography studies how terrain (the shape of the land), mountain passes, climate and location affect defence and war. Its sister discipline is military science.
• NCERT point (Class 11, the paragraph on geography and history):
• In the past, a large land area (spatial depth) and wide oceans protected countries.
• An invader had to cover long distances, so supply lines became long and weak.
• For example, Russia's huge size helped it against Napoleon (1812).
• Oceans kept the USA safe for a long time.

• Modern aircraft and missiles have reduced this protection.

• Indian examples:

Feature	Location	Why it matters for defence
Siachen Glacier	Eastern Karakoram Range, Ladakh; its meltwater feeds the Nubra river (→ Shyok → Indus)	Called the world's highest battlefield [10]. India took control of the whole glacier through Operation Meghdoot (1984), getting its troops there about a week before Pakistan's forces arrived [11]. It overlooks routes between Pakistan-occupied Kashmir and Aksai Chin.
Siliguri Corridor ("Chicken's Neck")	North West Bengal; Nepal lies to the west, Bangladesh to the south and Bhutan to the north, with China's Chumbi Valley close by	It is the only land link between mainland India and the eight north-eastern states. It is about 60 km long and about 22 km wide at its narrowest point [9].
Zoji La	Great Himalaya, on the Srinagar–Leh road	Leh's road link to Kashmir; snow closes it in winter
Karakoram Pass	Ladakh–Xinjiang (China)	Old trade route; lies near the Daulat Beg Oldi sector
Shipki La	Himachal Pradesh–Tibet	The Sutlej enters India here
Nathu La	Sikkim–Tibet (Chumbi Valley)	Border trade post; scene of the 1967 clashes
Bomdi La	Arunachal Pradesh	Route to Tawang; a battle front in 1962

• How climate affects defence:
• At high altitude the air has less oxygen and temperatures fall far below zero.
• Troops then suffer from frostbite and altitude sickness.
• Supplies must come by air or over passes that snow closes in winter.

4. Geopolitics: the idea

• Geopolitics: the study of how a state's location, size, resources and access to the sea shape its power and foreign policy.
• Rudolf Kjellen (Sweden) coined the word in 1899.
• Its roots: Friedrich Ratzel's organic state idea. Ratzel said a state is like a living thing that must grow and needs Lebensraum ("living space"). This idea belongs to the age of environmental determinism (the view that nature controls human life).

5. Sea power: Mahan (1890), the starting point

• Alfred Thayer Mahan (USA) wrote The Influence of Sea Power upon History, 1660–1783 (1890). He argued that sea power decides which nations rise to the top in history [8].
• His influence: he shaped the thinking of Theodore Roosevelt and Emperor Wilhelm II of Germany. This fed the naval race of the early 20th century [8].
• His main idea: control of sea lanes, naval bases and choke points brings trade, and trade brings power. Britain is his main example.

6. Heartland theory: Mackinder (1904, 1919)

• Halford Mackinder (Britain) set out the Heartland theory in "The Geographical Pivot of History" (1904). He said that whoever controls interior Asia and eastern Europe holds the key to world power [2].
• Why land power can now beat sea power [2]:
• Railways opened up the vast interior of Eurasia.
• Land armies could now move across the continent quickly.

• So a land power in the interior could challenge sea powers like Britain.

• The Pivot / Heartland:

• It runs roughly from the Volga to eastern Siberia.
• Its rivers drain into the frozen Arctic Ocean or into inland seas (Caspian, Aral).

• So navies cannot reach it, and that makes it safe from sea power.

• 1919 revision (Democratic Ideals and Reality): Mackinder added East Europe as the gateway to the Heartland [2]. His famous formula:

  "Who rules East Europe commands the Heartland; who rules the Heartland commands the World-Island; who rules the World-Island commands the World."

• World-Island: Europe, Asia and Africa taken together.

• The danger he saw: any single state that controls the Heartland could build a worldwide empire [2].

7. Rimland theory: Spykman (1944)

• Nicholas Spykman (USA) wrote The Geography of the Peace (1944).
• Rimland: the coastal belt of Eurasia that runs in a crescent from Europe to East Asia [3]. It takes in western Europe, the Middle East, South Asia and East Asia.
• Why the Rimland matters more than the Heartland:
• The Rimland is a meeting zone (amphibious zone). It has both land power and sea power.
• Most of the world's people, industry and ports are found here.

• Spykman said this belt tends to come under one state's control, and that state would rule the world [3].

• His dictum: "Who controls the Rimland rules Eurasia; who rules Eurasia controls the destinies of the world."

Point	Heartland (Mackinder)	Rimland (Spykman)
Year	1904; revised 1919	1944
Key zone	Interior of Eurasia (Volga to eastern Siberia)	Coastal rim (western Europe to East Asia)
Type of power	Land power	Land power + sea power together
Gateway	East Europe	Coastal states and sea lanes
Cold War use	Seen as the Soviet core	Basis of containment

8. Relevance today

• Cold War: the US policy of containment used Rimland thinking. It ringed the USSR with alliances along Eurasia's rim:
• NATO in western Europe.
• CENTO in the Middle East.

• SEATO in South-East Asia.

• Indo-Pacific: one strategic space that joins the Indian and Pacific Oceans. India sits at the centre of its rim.

• China's Belt and Road Initiative:
• The overland "Belt" runs through the Heartland.

• The maritime "Road" runs along the Rimland's coasts and ports.

• India's position on the Rimland:

• The Indian peninsula juts into the Indian Ocean.
• It lies near choke points such as the Strait of Malacca and the Strait of Hormuz.
• It also faces the Himalayan land frontier.

• See india-neighbours and world-trade.

• How these ideas were misused:

• Karl Haushofer's German school of Geopolitik turned Ratzel's Lebensraum into a reason for Nazi expansion.
• Geopolitics was discredited for decades after 1945 (see Section 2).

Prelims Hooks

• Sister disciplines (NCERT Table 1.2): political geography → political science; electoral geography → psephology; military geography → military science.
• "Geopolitics" was coined by Rudolf Kjellen (Sweden, 1899). It was not coined by Ratzel, Mackinder or Haushofer.
• Chronological order: Mahan's sea power (1890) → Kjellen's "geopolitics" (1899) → Mackinder's Heartland (1904) → Mackinder's revision (1919) → Spykman's Rimland (1944).
• "Who rules East Europe commands the Heartland…" is Mackinder (1919). "Who controls the Rimland rules Eurasia…" is Spykman (1944).
• Gerrymandering comes from Elbridge Gerry, Governor of Massachusetts, 1812. The odd-shaped district looked like a salamander [7].
• Delimitation: the present constituencies are based on Census 2001 under the Delimitation Act, 2002. They are frozen until the first census after 2026 [5][6]. The power comes from Article 82 [5].
• Delimitation Act, 2002: every Assembly constituency must lie wholly within one Parliamentary constituency [4].
• Siliguri Corridor: in West Bengal, about 22 km wide at its narrowest. It lies between Nepal and Bangladesh, with Bhutan to the north [9].
• Siachen Glacier: in the Karakoram (not the Great Himalaya). It is the world's highest battlefield and was secured by Operation Meghdoot, 1984 [10][11].
• Pass–state pairs: Shipki La → Himachal Pradesh (Sutlej entry); Nathu La → Sikkim; Bomdi La → Arunachal Pradesh; Zoji La → Srinagar–Leh road.

Mains Points

• Geography as a basis for strategy: Mackinder's land-power view and Spykman's rim view explain the US Cold War policy of containment. They also explain today's rivalry between China's Belt and Road Initiative and the Indo-Pacific framework. India's peninsular position on the Rimland, close to the Malacca and Hormuz choke points, gives it a key role at sea.
• Weak spots in India's military geography:
• The Siliguri Corridor (about 22 km wide) is India's only land link to the north-east [9].
• Passes closed by snow and high-altitude posts such as Siachen [10] need special supply lines, all-weather roads and tunnels.

• The old protection of size and oceans has been reduced by air power and missiles (NCERT).

• Electoral geography and fair representation:

• The rules on compact areas and administrative boundaries guard against gerrymandering [4].
• But the freeze until after 2026 [5] has kept seats tied to old population figures.

• Southern states fear losing seat share to faster-growing northern states, which is a federal fault line.

• Danger of determinism: Ratzel's organic state and Haushofer's Geopolitik show how environmental determinism was used to justify conquest. This is one reason human geography moved towards possibilism and neo-determinism.
