The Act and Treaty of Union of 1707 between the Parliaments of England and Scotland created a Kingdom of Great Britain which consisted of England (which incorporated Wales) and Scotland. In 1801 the Act of Union, passed by the British and Irish Parliaments, created a new United Kingdom of Great Britain and Ireland. After the 1922 Anglo–Irish Treaty this became the United Kingdom of Great Britain and Northern Ireland, the name the country retains to this day.
