 Following the Union of the Crowns of England, Ireland and Scotland in 1603, the Royal Standard of Scotland was incorporated into the royal standards of successive Scottish then, following the Acts of Union in 1707, British monarchs; with all such royal standards being quartered to include the banner of the arms of each individual realm. Since 1603, the Royal Banner of Scotland has appeared in both the first and fourth quarters of the quartered royal standard used in Scotland, while appearing only in the second quarter of that version used elsewhere.
