Great Britain
The political union that joined the kingdoms of England and Scotland happened because of the Acts of Union 1707. These acts of parliament merged the two nations' parliaments (the Parliament of Scotland and the Parliament of England), and joined the two kingdoms into a new Kingdom of Great Britain, or the United Kingdom of Great Britain. The whole island became one kingdom in this way on 1 May 1707, while Anne as queen. The Union Jack changed to its present design, which now has another saltire.
