Union Jack

"What are your orders "Wicked Will"? Shall we raise the Union Jack... ...or the Jolly Roger?"

- Elizabeth Swann and Jack Sparrow to Will Turner

The Union Jack is the flag of the Great Britain.

History
When King James VI of Scotland ascended to the English throne, thereby becoming James I of England, the national flags of England and Scotland on land continued to be, respectively, the red St. George's Cross and the white St. Andrew's Cross. Confusion arose, however, as to what flag would be appropriate at sea. On 12 April 1606 a proclamation was issued:
 * "All our subjects in this our isle and kingdom of Great Britain and the members thereof, shall bear in their main top the red cross commonly called St. George's Cross and the white cross commonly called St. Andrew's Cross joined together according to a form made by our heralds and sent to our Admiral to be published to our said subjects."

However, the flag was for use only at sea in civil and military ships of both Scotland and England. In 1634 its use was restricted to the king's ships. The flag went out of use in 1649 when England became a commonwealth but was restored for use in the king's ships after the restoration in 1660. The flag became "the ensign armorial of the United Kingdom of Great Britain" as one of the provisions of the Act of Union in 1707, when the kingdoms of England and Scotland were united.
