When did the man for whom Robert Carr was a favourite become King of Scotland?
James VI and I James VI and I (James Charles Stuart; 19 June 1566 – 27 March 1625) was King of Scotland as James VI from 24 July 1567 and King of England and Ireland as James I from the union of the Scottish and English crowns on 24 March 1603 until his death. The kingdoms of Scotland and England were individual sovereign states, with their own parliaments, judiciary, and laws, though both were ruled by James in personal union.
Kenneth MacAlpin Cináed mac Ailpin (Modern Gaelic: "Coinneach mac Ailpein "), commonly anglicised as Kenneth MacAlpin and known in most modern regnal lists as Kenneth I (810 – 13 February 858), was a king of the Picts who, according to national myth, was the first king of Scots. He was thus later known by the posthumous nickname of An Ferbasach , "The Conqueror". The dynasty that ruled Scotland for much of the medieval period claimed descent from him, and the current British monarch, Queen Elizabeth II is descended from him through Malcolm III, Robert the Bruce and James VI and I.
