Etymology and Terminology

The name "United Kingdom of Great Britain and Northern Ireland" originates from the Acts of Union 1707 uniting England and Scotland into Great Britain, later extended by the Acts of Union 1800 merging Great Britain with Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland, with the title modified after the Irish Free State formation and the Anglo-Irish Treaty. The term "Great Britain" derives from Britannia and the Roman province of Britannia (Roman province), while "United Kingdom" reflects successive parliamentary unions such as the Union of the Crowns 1603 and later statute unions including the Treaty of Union (1706). Official usage appears in instruments like the Treaty of Union and royal proclamations associated with the Hanoverian succession and the Act of Settlement 1701.
