Jacobean debate on the Union
The Jacobean debate on the Union took place in the early years of the reign of James I of England, who came to the English throne in 1603 as James VI of Scotland, and was interested in uniting his Kingdoms of England (including Wales) and Scotland. With one monarch on the two thrones there was a personal union; since James was very widely accepted in England, the debate was not on that plane.
