All capitals of Europe

Capital cities of Europe: key facts and context

Europe has 45 capitals. The largest is Moscow at 12.6 million residents; the smallest is Vatican City, an independent city-state with a permanent population of just 825. Podgorica became the capital of an independent Montenegro in 2006. Nicosia, the capital of Cyprus, has been divided since 1974 into Greek Cypriot and Turkish Cypriot zones by the UN Buffer Zone, making it the only capital city in the world that remains formally partitioned. Switzerland officially has no capital: Bern is designated the federal city and hosts the federal government, but is not constitutionally recognized as the capital. Several European capitals are not the most populous city in their country. Amsterdam is the Netherlands' constitutional capital, but the government and parliament sit in The Hague; Ankara is Turkey's capital, while Istanbul, with over four times Ankara's population, is the country's largest city. The choice of Ankara as Turkey's capital in 1923 was a deliberate political decision to move the center of power away from the cosmopolitan, Ottoman-era Istanbul.

Frequently Asked Questions

• Which European capitals are not the largest city in their country, and how did this come about?

  Several European capitals are smaller than their country's largest city. Amsterdam is the constitutional capital of the Netherlands, but the government and parliament are based in The Hague. Ankara is Turkey's capital while Istanbul is nearly five times larger. Bern is Switzerland's federal city, though Zurich is considerably larger and economically dominant. These arrangements reflect historical and political compromises rather than population size.

• Why did Atatürk choose Ankara over Istanbul as Turkey's capital in 1923?

  Atatürk chose Ankara because Istanbul was closely associated with the Ottoman Empire and was politically vulnerable as a coastal city that had been occupied by Allied forces after World War I. Ankara's central position on the Anatolian plateau made it more strategically defensible. The choice was also symbolic: the new republic deserved a capital untainted by the legacy of the old imperial order.

• Which European capitals host the headquarters of a major international organization?

  Brussels hosts both NATO headquarters and the main EU institutions, including the European Commission and the Council of the EU. Vienna is home to the International Atomic Energy Agency (IAEA) and OPEC. Bern hosts the Universal Postal Union, one of the world's oldest international organizations. The Hague — the seat of the Dutch government — hosts the International Court of Justice and the International Criminal Court, making it a global center for international law.

• Why is Nicosia the world's only formally divided capital city?

  Nicosia was divided in 1974 after a Greek Cypriot coup prompted a Turkish military intervention. A UN buffer zone known as the Green Line runs through the city, separating the Greek Cypriot south from the Turkish Cypriot north. Northern Cyprus is internationally recognized only by Turkey. Pedestrian crossing points were partially opened in 2003, after nearly three decades of complete separation.

• Which European country has no official capital city by law, and how does its government function?

  Switzerland has no constitutionally designated capital. Bern is referred to as the Bundesstadt (federal city) and hosts the federal parliament, federal council, and most ministries, but holds no formal capital status under Swiss law. The choice of Bern in 1848 was a deliberate compromise: its central geographic position made it neutral enough to satisfy all of Switzerland's linguistic communities.

• What is the population difference between Europe's most and least populous capital?

  Moscow is Europe's most populous capital with approximately 12.6 million residents. Vatican City has only around 825 permanent residents — the least populous sovereign capital in the world. The difference between the two is a factor of more than 15,000, the most extreme contrast between any two European capitals. This illustrates that capital status says nothing about a city's size.

• Why did Germany move its capital from Bonn back to Berlin after reunification?

  Bonn was chosen in 1949 as a deliberately modest temporary capital for West Germany, with reunification and a return to Berlin envisioned as the long-term goal. After the fall of the Berlin Wall and German reunification in 1990, the Bundestag voted narrowly in 1991 (338 to 320) to move the government back to Berlin. The physical relocation of parliament and most ministries was completed in 1999.

• How did Saint Petersburg as a former Russian capital shape Russia's relationship with Europe?

  Peter the Great founded Saint Petersburg in 1703 as Russia's imperial capital, deliberately orienting it toward Western Europe architecturally and culturally, modeled on Amsterdam and Venice. The city served as the capital of the Russian Empire from 1712 to 1918. After the Bolshevik Revolution, the capital moved back to Moscow. The city was renamed Petrograd in 1914, Leningrad in 1924, and restored to Saint Petersburg by referendum in 1991.

• Which European capital has undergone the most notable name changes in modern history?

  Saint Petersburg is the most prominent example: renamed Petrograd in 1914, Leningrad in 1924, and restored to Saint Petersburg by public referendum in 1991. Each renaming marked a political rupture. Kyiv, Chisinau, and Tallinn are other European capitals that changed names under shifting occupation or after independence, with each new name signaling a new political identity.

• Why has Podgorica only formally been the capital of a sovereign state since 2006?

  Podgorica became the capital of independent Montenegro after 55.5% of voters chose independence from the State Union of Serbia and Montenegro in a referendum. Before 2006, Podgorica already served as the administrative center, but sovereignty gave it full capital status. Montenegro's independence made it the first European state established through a democratic referendum in the 21st century.
