how did scotland become part of the united kingdom
History of Scotland James VI, Stuart king of Scotland, also inherited the throne of England in 1603, and the Stuart kings and queens ruled both independent kingdoms until the Act of Union in 1707 merged the two kingdoms into a new state, the Kingdom of Great Britain.[2][3][4]
United Kingdom of Great Britain and Ireland The growing desire for Irish self-governance led to the Irish War of Independence after the First World War, which resulted in most of Ireland seceding from the Union and forming the Irish Free State in 1922. Northern Ireland remained part of the United Kingdom, and the state was consequently renamed the "United Kingdom of Great Britain and Northern Ireland".
