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]
Wikipedia:Nationality of people from the United Kingdom Under British law, these four countries are an equal union, sharing a common British citizenship. The term "Britain" here means "the United Kingdom of Great Britain and Northern Ireland". A UK passport describes its holder as a "British citizen". According to British nationality law all citizens of the UK have British nationality.[2] This has been so since the Acts of Union 1707,[3] in which, after negotiations for a union treaty ended in July 1706, the acts were ratified by both the parliaments of England and Scotland.[4] "Great Britain" strictly speaking means the island comprising England, Scotland and Wales, and thus does not include Northern Ireland, so it is not the same as "Britain".
