Why Isn't the Biggest City the Capital? Five Reasons Countries Choose

Ask people for Australia’s capital and many say “Sydney!” The answer is Canberra. Canada’s is Ottawa, not Toronto. Brazil’s is Brasília, not Rio de Janeiro. Türkiye’s is Ankara, not Istanbul. Why did these countries pass over their biggest, most famous city?

Reason 1. When two cities fight, choose a third

When Australia federated in 1901, Sydney and Melbourne both wanted to be the capital. The solution was to build an entirely new city between them, and the Canberra site was chosen in 1908. An international design competition was won by American architects Walter Burley Griffin and Marion Mahony Griffin, and Parliament only moved to Canberra in 1927.

Washington, D.C. has a similar story. The Residence Act of 1790 placed a new capital on the Potomac River between North and South, and the government moved there in 1800, as part of a wider political compromise of the time.

Reason 2. Easier to defend

Canada’s Ottawa was chosen by Queen Victoria in 1857. With Toronto, Montreal, Quebec City and Kingston competing, its location on the border between English- and French-speaking regions, and its distance from the then-tense US border, are often cited as reasons.

Reason 3. To develop the interior

Brazil’s population and economy were concentrated on the coast. To push development inland, it built a brand-new planned city on a central plateau and moved the capital there in 1960. Lúcio Costa designed the city plan, which from above looks like an airplane or a bird, and architect Oscar Niemeyer designed its striking curved buildings.

Reason 4. A symbol of a new start

When Türkiye founded its republic in 1923, it chose Ankara in the middle of the Anatolian plateau instead of Istanbul, the Ottoman capital. Breaking with the old empire and beginning a new nation was a big part of the meaning.

Reason 5. Neutral ground

In 1991, Nigeria moved its capital from coastal Lagos to Abuja, a planned city in the center of the country, choosing a neutral location that didn’t favor any single region or ethnic group.

Capitals are still moving

This isn’t just history. Myanmar moved its government from Yangon to the newly built Naypyidaw in the mid-2000s, and Indonesia is building a new capital on Borneo because of overcrowding and sinking ground in Jakarta.

And Switzerland has no capital defined by law at all. Bern, home of the federal government, is called the “federal city” and treated as the de facto capital.

“Biggest city = capital” is often wrong, which is exactly why capital quizzes are full of traps.
