On 1 May 1707, the Kingdom of Great Britain[24][25] was created by the political union of the Kingdom of England (which included Wales) and the Kingdom of Scotland. This event was the result of the Treaty of Union that was agreed on 22 July 1706,[26] and then ratified by both the Parliament of England and Parliament of Scotland each passing an Act of Union in 1707. Almost a century later, the Kingdom of Ireland, already under English control by 1691, joined the Kingdom of Great Britain with the passing of the Act of Union 1800.[27] Although England and Scotland had been separate states prior to 1707, they had been in personal union since the Union of the Crowns in 1603, when James VI King of Scots had inherited the throne of the Kingdoms of England and Ireland and moved his court from Edinburgh to London.[28][29]
