The national emblem of the United Kingdom is the "Royal Coat of Arms of the United Kingdom." It is the official emblem representing the sovereignty and authority of the British monarch and the United Kingdom as a whole. The Royal Coat of Arms consists of several key elements:
Shield: The shield is divided into four sections, each representing different parts of the United Kingdom. The three lions passant guardant in the first and fourth quarters represent England, the lion rampant in the second quarter represents Scotland, and the harp in the third quarter represents Ireland.
Crest: Above the shield, there is a royal crown representing the monarchy. On top of the crown, there is a lion standing on its hind legs, holding a sword and a scepter, symbolizing the sovereign's authority.
Supporters: On either side of the shield, there are two supporters. The supporter on the left side is a lion representing England, and the supporter on the right side is a unicorn representing Scotland. They both hold flags and stand on a compartment featuring a rose (representing England), a thistle (representing Scotland), a shamrock (representing Ireland), and a leek (representing Wales).
Motto: The motto "Dieu et mon droit" (French for "God and my right") is written on a banner below the shield, signifying the monarch's claim to divine authority.
The Royal Coat of Arms of the United Kingdom is used by the British government, royal institutions, and other official representations of the country.
