Royal coat of arms of Great Britain

The Royal Arms of Great Britain from 1714 to 1801, with crest, supporters and motto

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 (ratified by the Acts of Union 1707), 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On 1 January 1801, the royal arms of Great Britain were superseded by those of the United Kingdom of Great Britain and Ireland, when Great Britain was united with the Kingdom of Ireland by the Acts of Union of 1800 following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.

	1603–1689	James VI, King of Scots inherited the English and Irish thrones in 1603 (Union of the Crowns), and quartered the Royal Arms of England with those of Scotland. For the first time, the Royal Coat of Arms of Ireland was added to represent the Kingdom of Ireland.[1] (The Scottish version differs in giving the Scottish elements more precedence.)
	1649–1654	These novel arms, already in use by parliamentarians in 1648, were adopted by the Commonwealth of England established in 1649.[2]
	1654–1655	The Commonwealth of England, Scotland and Ireland (the Protectorate) was created in 1653. St Andrew's Cross was added to the arms in 1654.[3]

Struck in 1655, the Great Seal included the personal arms Oliver Cromwell on a shield in the centre.[1] Blazon: Quarterly 1 and 4 Argent a Cross Gules (England) 2 Azure a Saltire Argent (Scotland) and 3 Azure a Harp Or Stringed Argent (Ireland) on an Inescutcheon Sable a Lion Rampant Argent (Cromwell's arms). The supporters were a crowned lion of England and a red dragon of Wales. The Scottish unicorn was removed, as it was associated with the Stuart Monarchy. The motto read PAX QUÆRITUR BELLO ("peace is obtained through war").[4]
	1659–1660	Following the Protectorate, the 1654 arms were restored.
	1603–1689	Charles II restored the Royal Arms following the restoration after the civil wars.

As King and Queen Regnant they impaled their arms: William bore the Royal Arms with an escutcheon of Nassau (the royal house to which William belonged) added (a golden lion rampant on a blue field), while Mary bore the Royal Arms undifferenced.[5][6]
	1694–1702	After the death of Mary II, William III reigned alone, and used his arms only.[1][5]
	1702–1707	Queen Anne inherited the throne upon the death of King William III & II, and the Royal Arms returned to the 1603 version.[1]
