After Queen Elizabeth 1 of England died in 1603, King James VI of Scotland inherited the English throne and became King James I of England. It was a Union of the Crowns, but not yet of the nations. Each country still kept their own parliaments. Early in his reign James attempted to combine England and Scotland in a united kingdom of 'Great Britain'. This was the policy he presented to his first Parliament, called on 22 March 1604. The union was resisted.James defied them. On 20 October 1604 he proclaimed a new title for himself as 'King of Great Britain'.But what flag should be used? (http://resources.woodlands-junior.kent.sch.uk/geography/unionjack3.html)

9The National Flags of Scotland and England were united for use at sea, thus making the first Union 'Jack'.

When the red cross of England was put onto the flag of Scotland, a white border was added around the red cross for reasons of heraldry. (The rules of heraldry demanded that two colors must never touch each other.)http://resources.woodlands-junior.kent.sch.uk/geography/unionjack3a.html

The Welsh dragon does not appear on the flag because when the first Union Flag was created in 1606, Wales was already united with England from the 13th century. This meant that Wales a Principality instead of a Kingdom and as such could not be included.In 1536, under Henry VIII, the Act of Union joined England and Wales officially. 13
