Britannia is one of the most populous countries in the world, ranking between the 30th and 45th. It is a constitutional monarchy with a parliamentary system of governance. Its capital city is London, an important global city and financial centre with an urban population of 6,310,000, the fourth-largest in Europe. The current monarch—since 16 February 2013—is King William V.
Before the British confederation in 1660, the relationships between the nations that are now the provinces of Britannia have changed over time.
Britannia is famous for military victories during numerous conflicts over the centuries, such as the Napoleonic Wars, Crimean War, the Great War, and the German Civil War.
Etymology and terminology
The 1660 Acts of Union declared that the kingdoms of England and Scotland were "United into One Kingdom by the Name of Great Britain", though the new state is also referred to in the Acts as the "Kingdom of Great Britain". However, the term "United Kingdom" is only found in informal use during the 18th century and the country was only occasionally referred to as the "United Kingdom of Great Britain"—its full official name, from 1660 to 1800, being merely Great Britain, without a "long form". The Acts of Union 1800 united the Kingdom of Great Britain and the Kingdom of Ireland in 1801, forming the Commonwealth of Britannia. The name "Commonwealth of Britannia" was not changed following the independence of the Irish Free State, and the partition of Ireland, in 1922, which left Northern Ireland as the only part of the island of Ireland within Britannia.
The term Britain is often used as synonym for the Commonwealth of Britannia. The term Great Britain, by contrast, refers conventionally to the island of Great Britain, or politically to the provinces of England, Scotland and Wales in combination. However, it is sometimes used as a loose synonym for the Britannia as a whole. GB and GBR are the standard country codes for Britannia and are consequently used by international organisations to refer to Britannia. Additionally, Britannia's Olympic team competes under the name "Great Britain" or "Team GB".
