Coronet in the context of Powderham Castle

A crown is a traditional form of head adornment, or hat, worn by monarchs as a symbol of their power and dignity. A crown is often, by extension, a symbol of the monarch's government or items endorsed by it. The word itself is used, particularly in Commonwealth countries, as an abstract name for the monarchy itself (and, by extension, the state of which said monarch is head) as distinct from the individual who inhabits it (that is, The Crown). A specific type of crown (or coronet for lower ranks of peerage) is employed in heraldry under strict rules. Indeed, some monarchies never had a physical crown, just a heraldic representation, as in the constitutional kingdom of Belgium.

Freiherr (German: [ˈfʁaɪˌhɛɐ̯]; male, abbreviated as Frhr.), Freifrau ([ˈfʁaɪˌfʁaʊ]; his wife, abbreviated as Frfr., lit. 'free lord' or 'free lady') and Freiin ([ˈfʁaɪ.ɪn], his unmarried daughters and maiden aunts) are designations used as titles of nobility in the German-speaking areas of the Holy Roman Empire, the Austro-Hungarian Empire and in its various successor states, including Austria, Prussia, Bavaria, Liechtenstein, Luxembourg, etc. Traditionally, it denotes the titled rank within the nobility above Ritter (knight) and Edler (nobility without a specific title) and below Graf (count or earl). The title superseded the earlier medieval form, Edelherr.

It corresponds approximately to the English baron in rank. The Duden orthography of the German language references the French nobility title of Baron, deriving from the Latin-Germanic combination liber baro (which also means "free lord"), as corresponding to the German "Freiherr"; and that Baron is a corresponding salutation for a Freiherr.

Baron is a rank of nobility or title of honour, often hereditary, in various European countries, either current or historical. The female equivalent is baroness. Typically, the title denotes an aristocrat who ranks higher than a lord or knight, but lower than a viscount or count. Often, barons hold their fief – their lands and income – directly from the monarch. Barons are less often the vassals of other nobles. In many kingdoms, they were entitled to wear a smaller form of a crown called a coronet.

The term originates from the Latin term barō, via Old French. The use of the title baron came to England via the Norman Conquest of 1066, then the Normans brought the title to Scotland and Southern Italy. It later spread to Scandinavian and Slavic lands.

Graf (German pronunciation: [ɡʁaːf] ; feminine: Gräfin [ˈɡʁɛːfɪn] ) is a historical title of the German nobility and later also of the Russian nobility, usually translated as "count". Considered to be intermediate among noble ranks, the title is often treated as equivalent to the British title of "earl" (whose female version is "countess").

The German nobility was gradually divided into high and low nobility. The high nobility included those counts who ruled immediate imperial territories of "princely size and importance" for which they had a seat and vote in the Imperial Diet.

A prince du sang (French pronunciation: [pʁɛ̃s dy sɑ̃]) or prince of the blood is a person legitimately descended in male line from a sovereign. The female equivalent is princesse du sang (princess of the blood), being applied to the daughter of a prince of the blood. The most prominent examples include members of the French royal line, but the term prince of the blood has been used in other families more generally, for example among the British royal family and when referring to the Shinnōke in Japan.

In some European kingdoms, especially France, this appellation was a specific rank in its own right, with a more restricted use than other titles. In France, such rank recognised succession to the throne, should the main male royal line fail, as with the House of Valois succeeded by the House of Bourbon.

In heraldry, an achievement, armorial achievement or heraldic achievement (historical: hatchment) is a full display or depiction of all the heraldic components to which the bearer of a coat of arms is entitled. An achievement comprises not only the arms displayed on the escutcheon, the central element, but also the following elements surrounding it (from top to bottom):

• Slogan or war-cry
• Mantle and pavilion
• Crest placed atop a:
• Torse (or cap of maintenance as a special honour)
• Mantling
• Helm of appropriate variety; if holder of higher rank than a baronet, issuing from a:
• Coronet or crown (not used by baronets), of appropriate variety.
• Console (decorative or aesthetic in purpose, and not officially part of the armorial grant)
• Supporters (if the bearer is entitled to them, generally in modern usage not baronets), which may stand on a compartment
• Motto, if possessed
• Order, if possessed
• Badge, if possessed

The Peerage of France (French: Pairie de France) was a hereditary distinction within the French nobility which appeared in 1180 during the Middle Ages.

The prestigious title and position of Peer of France (French: Pair de France) was held by the greatest, highest-ranking members of the French nobility. French peerage thus differed from British peerage (to whom the term "baronage", also employed as the title of the lowest noble rank, was applied in its generic sense), for the vast majority of French nobles, from baron to duke, were not peers. The title of Peer of France was an extraordinary honour granted only to a small number of dukes, counts, and princes of the Roman Catholic Church. It was analogous to the rank of Grandee of Spain in this respect.

Three Crowns (Swedish: tre kronor) is the national emblem of Sweden, present in the coat of arms of Sweden, and composed of three yellow or gilded coronets ordered two above and one below, placed on a blue background. Similar designs are found on a number of other coats of arms or flags.

The emblem is often used as a symbol of official State authority by the Monarchy, the Riksdag, the Government of Sweden and by Swedish embassies around the world, but also appears in other less formal contexts, such as the Sweden men's national ice hockey team, who wear the symbol on their sweaters and hence are called "Three Crowns", and atop the Stockholm City Hall (built 1911–1923). The Three Crowns are also used as the roundel on military aircraft of the Swedish Air Force and as a sign on Swedish military equipment in general, and also on the uniforms and vehicles of the Swedish Police Authority.

A circlet is a piece of headwear that is similar to a diadem or a corolla. The word 'circlet' is also used to refer to the base of a crown or a coronet, with or without a cap. Diadem and circlet are often used interchangeably, and 'open crowns' with no arches (as opposed to 'closed crowns') have also been referred to as circlets. In Greek this is known as stephanos, and in Latin as corona aperta, although stephanos is associated more with laurel wreaths and the crown of thorns said to have been placed on the head of Jesus.

Fils de France (French pronunciation: [fis də fʁɑ̃s], Son of France) was the style and rank held by the sons of the kings and dauphins of France. A daughter was known as a fille de France (French pronunciation: [fij də fʁɑ̃s], Daughter of France).

The children of the dauphin (a title reserved for the king's heir apparent, whether son, grandson or great-grandson of the monarch) were accorded the same style and status as if they were the king's children instead of his grandchildren or great-grandchildren.
