James the First
He ruled in Scotland as James VI from 24 July 1567, when he was only one year old, succeeding his mother Mary, Queen of Scots. Regents governed during his minority, which ended officially in 1578, though he did not gain full control of his government until 1581. On 24 March 1603, as James I, he succeeded the last Tudor monarch of England and Ireland, Elizabeth I, who died without issue. He then ruled England, Scotland and Ireland for 22 years, often using the title King of Great Britain, until his death at the age of 58.
