Royal Banner of Scotland: The Royal Banner of the Royal Arms of Scotland, also known as the Royal Banner of Scotland, or more commonly the Lion Rampant of Scotland, and historically as the Royal Standard of Scotland, (Scottish Gaelic: "Bratach rìoghail na h-Alba" , Scots: "Ryal banner o Scotland" ) or Banner of the King of Scots, is the Royal Banner of Scotland, and historically, the Royal Standard of the Kingdom of Scotland.  Used historically by the King of Scots, the banner differs from Scotland's national flag, the Saltire, in that its correct use is restricted by an Act of the Parliament of Scotland to only a few Great Officers of State who officially represent the Sovereign in Scotland.  It is also used in an official capacity at royal residences in Scotland when the Sovereign is not present.

Royal standard: Royal standard, royal flag, or royal banner may refer to:

Royal Arms of Scotland: The royal arms of Scotland was the official coat of arms of the King of Scots first adopted in the 12th century.  With the Union of the Crowns in 1603, James VI inherited the thrones of England and Ireland and thus his arms in Scotland were now quartered with the arms of England (which was itself quartered with France) with an additional quarter for Ireland also added (the arms would continue to alter in later years).  Though the kingdoms of England and Scotland would share the same monarch, the distinction in heraldry used in both kingdoms was maintained.  When the kingdoms of Scotland and England were united under the Acts of Union 1707 to form the United Kingdom of Great Britain, no single arms were created and instead, the royal arms as used in either Scotland and the rest of the United Kingdom would continue to differ.

Royal coat of arms of the United Kingdom: The royal coat of arms of the United Kingdom, or the Royal Arms for short, is the official coat of arms of the British monarch, currently Queen Elizabeth II.  These arms are used by the Queen in her official capacity as monarch of the United Kingdom.  Variants of the Royal Arms are used by other members of the British royal family; and by the British government in connection with the administration and government of the country.  In Scotland, there exists a separate version of the Royal Arms, a variant of which is used by the Scotland Office.  The arms in banner form serve as basis for the monarch's official flag, known as the "Royal Standard".

Royal Standard of Spain: The Royal Standard of Spain ("Estandarte Real or Estandarte del Rey") is the official flag of the King of Spain.  It comprises a crimson square, traditional colour of both Castilian and Spanish monarchs, with the coat of arms of the King in the center.  It is raised over the official royal residence in Madrid, the Palacio de la Zarzuela and other Spanish royal sites, when the monarch is in residence and displayed on his official car as small flag.  The current flag was adopted when Felipe VI acceded the throne as King of Spain on 19 June 2014.  The Royal Standard is regulated by Rule 2 of Royal Decree 527/2014, 20 June, an amendment to Title II of Spanish Royal Decree 1511/1977 adopting Flags, Standards, Guidons, Insignia and Emblems Regulation.

Monarchy of the United Kingdom: The monarchy of the United Kingdom, commonly referred to as the British monarchy, is the constitutional monarchy of the United Kingdom, its dependencies and its overseas territories.  The current monarch and head of state, Queen Elizabeth II, ascended the throne on the death of her father, King George VI, on 6 February 1952.

Flag of Scotland: The Flag of Scotland (Scottish Gaelic: "bratach na h-Alba" ; Scots: "Banner o Scotland" ), also known as St Andrew's Cross or the Saltire, is the Flag of Scotland.  As the national flag, the Saltire, rather than the Royal Standard of Scotland, is the correct flag for all individuals and corporate bodies to fly.  It is also, where possible, flown from Scottish Government buildings every day from 8am until sunset, with certain exceptions.

Bearer of the Royal Banner: The Bearer of the Royal Banner is one of the Great Officers of the Royal Household in Scotland.  The bearer participates in royal, state, and other ceremonial events when needed.

Royal standards of England: The royal standards of England were narrow, tapering swallow-tailed heraldic flags, of considerable length, used mainly for mustering troops in battle, in pageants and at funerals, by the monarchs of England.  In high favour during the Tudor period, the Royal English Standard was a flag that was of a separate design and purpose to the Royal Banner.  It featured St George's Cross at its head, followed by a number of heraldic devices, a supporter, badges or crests, with a motto—but it did not bear a coat of arms.  The Royal Standard changed its composition frequently from reign to reign, but retained the motto "Dieu et mon droit", meaning God and my right; which was divided into two bands: "Dieu et mon" and "Droyt".

Derafsh Kaviani: Derafsh Kaviani, or Derafsh Kavani, was the legendary royal standard (vexilloid) of Iran used since ancient times until fall of the Sasanian Empire.  Following the defeat of the Sassanids at the Arab conquest of Persia, the Sassanid standard was recovered by one Zerar bin Kattab, who received 30,000 dinars for it.  After the jewels were removed, Rashidun Caliph Umar is said to have burned the standard.  The banner was also sometimes called the "Standard of Jamshid" ("Drafš-ī Jamshid"), the "Standard of Fereydun" ("Drafš-ī Freydun") and the "Royal Standard" ("Drafš-ī Kayi").
