World Capitals Quiz: Test Your Geography Knowledge

World Capitals Trivia: Can You Name Them All?

From purpose-built cities to capitals that changed names, this free quiz covers the strangest stories behind the world's capital cities.

Here's a fact that trips up even geography nerds: more than 30 countries have a capital that isn't their largest city, and the gap can be enormous. Sydney has over 5 million people; Canberra has around 450,000.

Rio de Janeiro used to be Brazil's capital until the government got so tired of the coastal congestion that it built an entirely new city, Brasília, from bare red dirt in the middle of the country and moved everyone there in under four years. Capitals get chosen for reasons that have almost nothing to do with population — politics, compromise, sometimes pure stubbornness — and that's what makes them so much fun to quiz on.

This one's a rapid-fire round through capitals most people half-remember from school, plus a few genuine oddities: a capital that changes with the seasons, one that used to have a different name entirely, and one country that technically runs three capitals at once. See how many you can nail before checking the answer.

Fun fact

Bolivia doesn't have one capital — it has two. Sucre is the constitutional capital and seat of the judiciary, while La Paz houses the executive and legislative branches and functions as the country's seat of government. To make things even stranger, La Paz sits at roughly 3,650 meters above sea level, making it the highest seat of government on Earth.

Sample question explanations

Q: What is the capital of Myanmar?
Answer: Naypyidaw
The military government abandoned Yangon and built Naypyidaw practically overnight starting in 2005, reportedly on the advice of astrologers about auspicious timing. It has enormous multi-lane highways that sit almost completely empty, since the city was designed for a population it never quite attracted.

Q: Which South American capital was purpose-built and inaugurated in 1960?
Answer: Brasília
Architect Oscar Niemeyer designed the city's landmark buildings, and the entire layout was shaped like an airplane or a bird when viewed from above, depending on who you ask. It replaced Rio de Janeiro as Brazil's capital largely to shift development inland, away from the crowded coast.

Q: What is the smallest country in the world, and also serves as its own capital in a sense since the entire nation is one city?
Answer: Vatican City
At just 0.44 square kilometers, it's small enough that you could walk across the entire country in about 20 minutes. It's also the only country in the world with no permanent residential population in the traditional sense — most people who live there are clergy or Swiss Guards tied to the Holy See.*

Q: Which country officially recognizes three capital cities: one for administration, one for the judiciary, and one for the legislature?
Answer: South Africa
Pretoria handles the executive branch, Cape Town hosts parliament, and Bloemfontein is home to the Supreme Court of Appeal. The arrangement dates back to a political compromise made when the country unified in 1910, and nobody's ever managed to consolidate it since.

Q: What was Norway's capital, Oslo, called for roughly 300 years before reverting to its original name in 1925?
Answer: Christiania (later spelled Kristiania)
The city was renamed after King Christian IV rebuilt it following a devastating fire in 1624. It kept that name under Danish and then Swedish rule for centuries before Norwegians switched it back to Oslo after gaining full independence.

What this quiz is about

World capitals sound like the driest possible trivia category until you realize how much political drama, engineering ambition, and outright weirdness is baked into how these cities got chosen. This quiz picks the ones with the best stories behind them, not just the ones easiest to memorize from a map.
