The early years of the unified kingdom were marked by Jacobite risings which ended in defeat for the Stuart cause at Culloden in 1746. In 1763, victory in the Seven Years' War led to the dominance of the British Empire, which was to become the foremost global power for over a century and slowly grew to become the largest empire in history.
On 1 January 1801, the kingdoms of Great Britain and Ireland were merged to form the United Kingdom of Great Britain and Ireland. In 1922, 26 of the 32 Irish counties seceded and the state was renamed the United Kingdom of Great Britain and Northern Ireland – a title it has retained to date. Historians refer to the 18th-century state as Great Britain.
The name Britain descends from the Latin name for the island of Great Britain, Britannia or Brittānia, the land of the Britons via the Old French Bretaigne (whence also Modern French Bretagne) and Middle English Bretayne, Breteyne. The term Great Britain was first used officially in 1474.
The use of the word "Great" before "Britain" originates in the French language, which uses Bretagne for both Britain and Brittany. French therefore distinguishes between the two by calling Britain la Grande Bretagne, a distinction which was transferred into English.
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", 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". Both the Acts and the Treaty describe the country as "One Kingdom" and a "United Kingdom", which has led some much later publications into the error of treating the "United Kingdom" as a name before it actually came into being in 1801. 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. The term United Kingdom was sometimes used during the 18th century to describe the state, but was not its name.
