Cultural and Political Geography explained
What this unit covers
Culture and cultural realms
A culture region shares common cultural elements; it may be exceedingly large like the Islamic region, very small like Spanish Harlem or intermediate like the Corn Belt. The World Heritage Committee sees cultural landscapes as the combined works of nature and of man. There are twelve cultural realms, among them the Occidental, Islamic, Indie, East Asian, South-East Asian and Meso-African realms.
Races and religions
Human races are grouped into Negroid, Mongoloid, Caucasoid and Australoid. Religions are universalizing (Christianity, Islam, Buddhism), ethnic (Hinduism, Shintoism, Judaism) or tribal.
Tribes
The lesson places tribes by region, describes the Pigmies, Masai, Bedouin, Bushman and Eskimos, the Bhils, Gonds, Santhals and other Indian tribes, and the Todas, Badagas, Kotas, Kurumbas, Irulas and Paliyans of Tamil Nadu.
Language
G.L. Trage grouped the world's languages into 7 phylum and 30 families. India has 22 scheduled languages in four families. UNESCO gives five levels of language risk.
Political geography
Nation, state and nation-state; frontiers versus boundaries; antecedent, subsequent, superimposed and relict boundaries; Mackinder's Heartland, Inner Crescent and Outer Crescent; and the shift from a unipolar to a multipolar world.
Common mistakes to avoid
- Saying India has the most languages. Papua New Guinea (839) leads; India (780) is second.
- Giving Islam as an influence on Continental European culture. The book names Christianity.
- Counting the Badagas as a tribe. They belong to the backward class.
- Confusing relict boundaries with superimposed ones. Persia and the East-West Germany line are relict; Pakistan occupied Kashmir is superimposed.
- Placing Great Britain and Japan in the Inner Crescent. Their insularity puts them in the Outer or Insular Crescent.
Test yourself on these with the practice test, then check the worked reasoning in the solved MCQs.
Frequently asked questions
What is a cultural realm?
A cultural realm is a type of cultural region: a continuous geographical area marked by cultural homogeneity. Realms are classified on attitude, religious belief, language, racial group and technological development, and the lesson counts twelve cultural realms in the modern world.
What are the four major races?
Human races are grouped into Negroid, Mongoloid, Caucasoid and Australoid on features such as skin colour, stature, head shape, face, nose, eye, type of hair and blood group. Negroids live in Sub-Saharan Africa, Mongoloids in East Asia, Caucasoids in Europe and the Middle East, and Australoids in Australia and Papua New Guinea.
Which tribes live in Tamil Nadu?
Tribes of Tamil Nadu live mainly in the Nilgiris. The Kotas, Todas, Irulas, Kurumbas and Badagas form the larger groups, and others include the Kattunayakan and Paliyan. The 2011 census counted 7,94,697 tribal people in about 38 tribes and sub-tribes in the state.
What are the four language families of India?
Indian languages mainly belong to the Austric family (Munda, Mon-Khmer), the Dravidian family (Tamil, Telugu, Kannada, Malayalam, Gondi, Kurukh), the Sino-Tibetan family (Bodo, Karen, Manipuri) and the Indo-Aryan family (Hindi, Urdu, Sanskrit).
How is a frontier different from a boundary?
A frontier is a natural, areal zone without political dispute, usually mountains, desert or marsh, and it is dynamic. A boundary is a mostly man-made line that rival nations often dispute, and it is static because once fixed it hardly changes.
What is Mackinder's Heartland theory?
Mackinder divided the earth into the Heartland, the Inner or Marginal Crescent and the Outer or Insular Crescent. The Heartland was a natural fortress inaccessible to sea powers, with Eastern Europe as its only gateway, so whoever rules East Europe commands the Heartland, the World Island and the world.
