The capitals of the world: every trap in the quiz

Sydney, Istanbul, Rio, New York: four huge, world-famous cities, and not one of them is a capital. Capitals are the favourite playground of geography quizzes, because intuition gets them wrong almost every time.

A capital is a political choice, not a demographic fact. It is the city where the institutions sit — sometimes to balance regions against one another, sometimes to keep power away from an over-mighty metropolis, sometimes to create a national symbol where there was nothing. Hence the surprises.

When the capital is not the largest city

This is trap number one, and it affects a good twenty countries. The logic is almost always the same: settle a rivalry between two cities by choosing neither, or deliberately decentre power.

Canberra is the clearest example: Sydney and Melbourne were fighting over the title when the Australian federation formed in 1901. The solution was to build a new city halfway between them, on farmland. Washington follows the same logic — a federal district created between North and South, belonging to no state.

The countries with several capitals

Nothing obliges a country to concentrate its institutions in one place. A dozen states spread them out, and that is the second most common source of error.

Quiz reflex

When a country has several capitals, a well-built quiz accepts the main one and flags the others. When in doubt, the expected answer is almost always the seat of the executive: Pretoria for South Africa, La Paz for Bolivia — Amsterdam being the exception, since there the constitutional wording prevails.

The capitals built from scratch

Several countries created their capital from nothing, generally to rebalance a territory whose economic life was concentrated on the coast.

The records you would not guess

The free answers: capitals named after their country

One family of answers comes for free: countries whose capital carries, more or less, the name of the country. Mexico City in Mexico, Panama City in Panama, Guatemala City in Guatemala, Djibouti in Djibouti, Kuwait City in Kuwait, Tunis in Tunisia, Algiers in Algeria, San Marino in San Marino, Luxembourg in Luxembourg, Monaco in Monaco, Singapore in Singapore.

The same goes for small island states, where the capital is simply the only town: Malé in the Maldives, Nassau in the Bahamas, Victoria in the Seychelles.

The cities people think are capitals

Let us finish with the reverse list — the metropolises everyone names by reflex, wrongly: Istanbul, Sydney, Rio de Janeiro, New York, Toronto, Auckland, Casablanca, Lagos, Karachi, Almaty, Geneva, Zurich, Dar es Salaam, Milan, Barcelona, Mumbai. All better known than their country's capital, and none of them its institutional seat.

Geneva deserves a special mention: the city hosts the UN, the WHO, the WTO and the Red Cross — and Switzerland does not even use the word capital, preferring to call Bern its “federal city”, a cautious formulation that avoids the term altogether.

How many capitals do you really know?
