In the Act of Union of 1707, England and Scotland agreed to permanent union as Great Britain; the legislative union of Great Britain and Ireland was implemented in 1801, with the adoption of the name the United Kingdom of Great Britain and Ireland, but in 1921, the Anglo-Irish treaty formalized a partition of Ireland, although six northern Irish counties remained part of the United Kingdom and became known as Northern Ireland and the current name of the country is the United Kingdom of Great Britain and Northern Ireland. It was adopted in 1927.
