Modern capitals

Many modern capital cities are located near the centre of the country, so that they are more accessible to its population and have better protection from possible invasions. The location may also be based on a compromise between two or more cities or other political divisions, historical reasons, or enough land was needed to deliberately build a new planned city for the capital. The majority of national capitals are also the largest city in their respective countries. Modern examples are Beijing, Berlin, Cairo, London, Madrid, Mexico City, Moscow, Paris, and Tokyo.

Counties in the United Kingdom have historic county towns, which are often not the largest settlement within the county and often are no longer administrative centres, as many historical counties are now only ceremonial, and administrative boundaries are different. The number of new capitals in the world increased substantially since the Renaissance period, especially with the founding of independent nation-states since the eighteenth century.

In Canada, there is a federal capital, while the ten provinces and three territories each have capital cities. The states of such countries as Mexico, Brazil (including the famous cities of Rio de Janeiro and São Paulo, capitals of their respective states), and Australia also each have capital cities. For example, the six state capitals of Australia are Adelaide, Brisbane, Hobart, Melbourne, Perth, and Sydney. In Australia, the term "capital cities" is regularly used to refer to those six state capitals plus the federal capital Canberra, and Darwin, the capital of the Northern Territory. Abu Dhabi is the capital city of the Emirate of Abu Dhabi and also of the United Arab Emirates overall.

In unitary states which consist of multiple constituent nations, such as the United Kingdom and the Kingdom of Denmark, each will usually have its own capital city. Unlike in federations, there is usually not a separate national capital, but rather the capital city of one constituent nation will also be the capital of the state overall, such as London, which is the capital of England and of the United Kingdom. Similarly, each of the autonomous communities of Spain and regions of Italy has a capital city, such as Seville and Naples, while Madrid is the capital of the Community of Madrid and of the Kingdom of Spain as a whole and Rome is the capital of Italy and of the region of Lazio.

In the Federal Republic of Germany, each of its constituent states (or Länder, plural of Land) has its own capital city, such as Dresden, Wiesbaden, Mainz, Düsseldorf, Stuttgart, and Munich, as do all of the republics of the Russian Federation. The national capitals of Germany and Russia (the Stadtstaat of Berlin and the federal city of Moscow) are also constituent states of both countries in their own right. Each of the states of Austria and cantons of Switzerland also have their own capital cities. Vienna, the national capital of Austria, is also one of the states, while Bern is the (de facto) capital of both Switzerland and of the Canton of Bern.
