When the kingdom began, the Parliament of Scotland and the Parliament of England joined into one legislature, the Parliament of Great Britain. The parliament met in the old Palace of Westminster in London. London was the capital city and the British government was there. The two earlier kingdoms of Scotland and England had been in a personal union (sharing the same monarchy) since the reign of James VI and I. King James was a King of Scots who became King of England and King of Ireland in 1603 because he inherited the kingdoms of Elizabeth I.
