Capitals
In short
A capital is the city that serves as the official seat of government for a country or region. It is where leaders meet to make laws and run the state.
In plain words
Most countries pick one specific city to be their main centre of power. This is where the parliament, president, or king usually stays. It is the heart of a nation's politics.
A simple example
London is the capital of the United Kingdom. This means the UK government and Parliament are based there.
Why it matters
Capitals act as the central hub for administration and diplomacy. They allow a government to organise the country and communicate with other nations from one fixed spot.
Easy to mix up
Do not confuse a capital city with the largest or most famous city in a country, such as Sydney and Canberra in Australia.
