Royal Arms of England

Extracted from the Wikipedia article Coat of arms of England.
After the Union of the Crowns
Following the death of Elizabeth I in 1603, the throne of England was inherited by the Scottish House of Stuart, resulting in the Union of the Crowns: the Kingdom of England and Kingdom of Scotland were united in a personal union under James VI and I. As a consequence, the royal arms of England and Scotland were combined in the king's new personal arms. Nevertheless, although referencing the personal union with Scotland and Ireland, the royal arms of England remained distinct from the royal arms of Scotland, when the countries finally united in 1707, the English style of arms became the basis for the coat of arms of Great Britain, while Scotland retained its distinct arms.
