Royal coat of arms of Great Britain
The Royal coat of arms of Great Britain was the coat of arms representing royal authority in the sovereign state of the Kingdom of Great Britain, in existence from 1707 to 1801. The kingdom came into being on 1 May 1707, with the political union of the kingdom of Scotland and the kingdom of England, which included Wales. With the 1706 Treaty of Union, it was agreed to create a single kingdom, encompassing the whole of the island of Great Britain and its outlying islands, but not Ireland, which remained a separate realm under the newly created British crown.
On 1 January 1801, the royal arms of Great Britain were superseded by those of the United Kingdom of Great Britain and Ireland, when Great Britain was united with the Kingdom of Ireland by the Acts of Union of 1800 following the suppression of the Irish Rebellion of 1798.
