History
On 1 May 1707, the Kingdom of Great Britain came into being, the result of Acts of Union being passed by the parliaments of England and Scotland to ratify the 1706 Treaty of Union and so unite the two kingdoms. The term "United Kingdom" became official in 1801 when the parliaments of Britain and Ireland each passed an Act of Union, uniting the two kingdoms and creating the United Kingdom of Great Britain and Ireland.
