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",:Both Acts and the Treaty state in Article I: "That the Two Kingdoms of Scotland and England, shall upon 1 May next ensuing the date hereof, and forever after, be United into One Kingdom by the Name of GREAT BRITAIN".</ref> and as such "Great Britain" was the official name of the state, as well as being used in titles such as "Parliament of Great Britain". The websites of 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". Both the Acts and the Treaty describe the country as "One Kingdom" and a "United Kingdom", leading some publications to treat the state as the "United Kingdom". The term "United Kingdom" was sometimes used during the 18th century to describe the state.
