James I (1566-1625) was King of England from 1603 and Scotland (James VI) from 1567.
The son of Mary, Queen of Scots, and Lord Darnley, he succeeded on his mother's abdication from the Scottish throne, assumed power in 1583, established a strong centralized authority, and in 1589 married Anne of Denmark (1574-1619).
As successor to Elizabeth in England, he alienated the Puritans by his High Church views and Parliament by his assertion of divine right, and was generally unpopular because of his favourites, such as Buckingham, and because of his schemes for an alliance with Spain. He was succeeded by his son Charles I.
