The flag of England is one of the key components of the Union Flag. The Union Flag has been used in a variety of forms since the proclamation by Orders in Council 1606, when the flags of Scotland and England were first merged to symbolise the Union of the Crowns. (The Union of the Crowns having occurred in 1603). In Scotland, and in particular on Scottish vessels at sea, historical evidence suggests that a separate design of Union Flag was flown to that used in England.
