The wisest fool in Christendom, James VI.
James VI of Scotland inherited the English throne from Elizabeth I of England and became James I of England. As a resilt he is sometimes called James the Sixth and First.
James VI of Scotland became James I of England in 1603.
James VI of Scotland became James1 of England.
James VI of Scotland became James 1 of England
It's the other way round. James 1 (James 6 of Scotland) took the throne after the death of Elizabeth 1.
King James VI of Scotland inherited the English throne, becoming King James I of England. This united the countries of Great Britain, forming the United Kingdom.
Elizabeth I died in 1603 with no children. James VI of Scotland had strong but unrecognised claims to the English throne so he was invited to be King of England as well. Thus he became King James I of England and Ireland whilst quite separately being King James VI of Scotland.
Assuming you mean Queen Elizabeth II, that would be King George VI, her father.
Because he/she inherited the throne
Both. Fist he was contemporary (and wrote for) with Elisabeth I, whose throne was inherited by the King of Scotland, who became James I (and Shakespeare was his contemporary, too).
He was already James VI of Scots when Queen Elizabeth of England died. He was the heir to the English throne.
Elizabeth I died without issue (childless), so the succession passed to a cousin, James VI of Scotland, the son of Mary, Queen of Scots. When he took the throne after Elizabeth's death in 1603, he became James I of England. James and Elizabeth were both descended from Henry VII, and James was legitimately the next in line to the throne.
