"This article is about the historical state (1707–1800). For the modern state, see United Kingdom. For the island, see Great Britain. For other uses, see Britain (disambiguation).

The Kingdom of Great Britain, occasionally referred to as the United Kingdom of Great Britain, was a sovereign state in north-west Europe that existed from 1 May 1707 to 31 December 1800.

"The Treaty of Union and the subsequent Acts of Union state that England and Scotland were to be "United into one Kingdom by the Name of Great Britain". They describe the new state as the United Kingdom of Great Britain and the United Kingdom, using capital letters for such terms. The websites of the UK parliament, the Scottish Parliament, the BBC, and others, including the Historical Association, refer to the state created on 1 May 1707 as the United Kingdom of Great Britain. However, the state created by the union of England and Scotland in 1707 is named in the treaty as Great Britain; and is usually referred to by that name or as the Kingdom of Great Britain.

Should Scotland elect to go its own way (which it won't) on the 18th September 2014 then after 2016 the UK will still be known as the UK and carry on as normal. Scotland will have to find a currency, make up it's mind if it wants to apply for membership of the EU and NATO and a whole raft of other things including organising the referendum for those living in the Western isles, Orkney and Shetland to see if they wish to remain Scottish (If those islanders were sensible, particularly those living on Orkney and Shetland they would vote to return to Norway).
