A combined British flag was created in 1606 (after the dynastic union of England and Scotland in 1603, the so-called "Union of the Crowns") by combining Saint George's Cross with the Saint Andrew's Cross (the flag of Scotland). The flag was initially for maritime display, later restricted to the King's ships. Afterwards, the Saint George flag remained the flag of England for other purposes until the Acts of Union 1707. At the union, the first Union Flag became official for all purposes in the new Kingdom of Great Britain.
