[Thompsonshire]

Commoners

Thompsonshirean peasants are typically a simple folk, well adapted to the cold conditions on the icy moon Amor. Outside of their homes, 'tis rare to see them clad in anything less than a thick jacket, gloves, waterproof insulated trousers, boots with metal cleats, and a hat with insulated earflaps (though the hat, gloves, and jacket are occasionally removed indoors).

The Defenders of the Duchy comprise the less-elite, though still important, military force of the Grand Duchy. In order to be eligible for citizenship, a Peasant must enlist with the Defenders for at least 2 orbits of Amor around Caritas (just short of two Earth-years).

Defenders are regarded as gentlemen and gentlewomen; while they have nothing quite like the prestige of Knights or even Squires, Defenders are rigidly disciplined, unwavering in their sense of honor and pride. It is this discipline that serves as a foundation for skills eventually befitting a Knight.

Squires serve as subordinates and apprentices to Knights, often aiding them in battle. While not quite true nobles, Squires hold the most prestigious title a commoner may have before being elevated to nobility.

Nobles

Knights are the lowest of the nobility. However, even this relatively-low status confers a multitude of rights restricted only to the nobility - most notably of which including the right (even obligation) to own land; upon knighthood, every knight is granted a personal estate, though some have dedicated their lands to public use, particularly if they are descendants of existing knights and expect to inherit additional land.

Knights, along with their Squires, are typically found piloting aerospace fighters and corvettes; regarded as the "Cavalry of the Stars", Knights of the Grand Duchy have repeatedly proven their superiority in the vacuum of outer space.

Barons and Baronesses are a step above Knights, and are typically responsible for ruling over individual settlements. In the context of battle, Barons are equivalent to captains in most navies, commanding individual capital ships.

The House of Barons - the Duchy's equivalent to a parliament - consists of all Thompsonshirean Barons, representing their respective settlements.

Thompsonshirean Counts and Countesses are the highest class of nobility in which multiple persons may reside, though there currently exists only one Count: Sir Birgr Prästost, Count of Amicitia, and younger brother of Grand Duke Hilmar. Counts will typically control entire stellar systems, and answer only to the Duke (and even then). In the context of battle, a Count will frequently serve a position equivalent to an Admiral, commanding an entire fleet.

The Grand Duke or Grand Duchess of Thompsonshire holds the highest position in the Duchy (obviously). The current holder of this position is Grand Duke Hilmar Prästost, who founded Thompsonshire upon the colonization of Amor. Given the absence of non-Grand Dukes and Duchesses, 'tis acceptable in informal contexts to refer to the Grand Duke or Grand Duchess as simply "Duke" or "Duchess" (respectively), though this is typically frowned upon in formal contexts.

While there technically could be an additional position of "King" or "Queen" of Thompsonshire - making Thompsonshire a kingdom rather than a Grand Duchy - the choice of existing as a Grand Duchy was deliberate, as the Grand Duchy sought to coexist with the government of its parent nation - YellowApple, Inc. - rather than compete against it by declaring a "King" or "Queen" to rival the power of the Administrator and Voice of YellowApple. In this context, the Administrator was instead considered equivalent to a "King" or (in the case of current Administrator Fostera Manzano) "Queen". Even with Thompsonshire establishing its independence as a sovereign and autonomous nation, most Thompsonshireans - including the Grand Duke himself - are unwilling to deviate from the current hierarchy and establish a King or Queen above the Grand Duke (or even promote the Grand Duke to a position of "King").

[Nidemark]

Unlike many of the examples given Nidish nobility is not hierarchical, as the political system of the country is strictly speaking not feudal.

There exists only two ranks among the nobilty, or stormæn (great men).
Kung/Drottning (King/Queen)
Friherre/Friherrina (Baron/Baroness)

Both a baron and untitled nobility can also be knighted by the king and so take on the title 'herr riddare' (sir knight). This is a personal title and not inherited.

[Wuyiuih Kaonnoe]

The nation is ruled by an oligarchy of nobles, but they elect a regent to represent the interests of the nation. They do have a titular king, but the real power behind the nation is the regent. The regent position is elected, but the position is hereditary most of the time. Women do not lead public positions.

You have no right to judge other nation's ideology.

[Abserdia]

The greatest rank we have is Ruler, followed closely by Blackadder.
(He rides a pitch black STEED!)

[Artaeon]

You have no right to judge other nation's ideology.

Right, but this thread deals with ranks of Nobility, which commonly do not exist in a communist state.

[Theatrical Theists]

Hierarchy of nobility of the Theatrical Theists:

• Rav-Pope-Guru-Caliph (leader of the nation, and the faithful),
• Rav-Cardinal-Guru-Mawlawi (member of the College of Ravanim-Cardinals-Gurus-Mawlana, which functions as the Rav-Pope-Guru-Caliph's cabinet),

[Wintanceastre]

Royalty:

King
Currently the constitutional head of state and head of church. Originally established in 873 AD by Darjo Fiwerjo, who established the unified Wintonian kingdom. The title was abolished temporarily after the island was colonised; and was later reestablished and was claimed by King Henry VIII of England or Henry of Wintanceastre. After the nation gained its independence, the title of King was granted to James I.

Queen
This title falls beneath the King, and does have subdivisions. The Queen Consort is the wife of the King of Wintanceastre, while the Queen Regnant is a queen in her own right with all the powers of a monarch. The title of Queen was established in 1510 when King Henry VIII reestablished the title of King.

Prince
"Prince" or "Princess" usually refers directly to the children and grandchildren
of the reigning Monarch, most notably the Crown Prince (or Princess) who is heir to the throne. If the Monarch
is a Queen, the the Queen's consort will usually be a Prince. The spouse of the Heir will also become a Prince or Princess, however spouses of Princes (or Princesses) who are not the Heir will become Dukes or Duchesses.

---

Bishops

Archbishop
There are three Archbishops in the Church of Wintanceastre,
who have jurisdiction over a third of the country each,
corresponding to the three historic provinces of Wintanceastre.
While the King is the de jure head of the Church,
the Archbishops are the day-to-day governors, and are
also present when a new King is crowned.

Bishops
Bishops are members of the clergy who are ordained
by the laying on of hands of another bishops, with
this lineage believed to have gone back to the Apostles

Priests

Priest
A priest is the head of a parish,
and typically works with a deacon in serving
the people and peforming religious services.

Deacon
deacons often work directly in ministry to the marginalised
inside and outside the church: the poor, the sick,
the hungry, the imprisoned. They usually are working
to be ordained as a priest.

Nobility

Duke
There is considerable crossover between "Prince" and "Duke" which often causes confusion. All Princes are Dukes, but not all Dukes are Princes. Generally speaking a Duke refers to any member of the Royal Family, including those who marry into it and the descendants thereof. While Dukes are not always in line to the throne (and in modern times they scarcely are), they will always have some sort of family connection to the Monarchy, however distant.

Marquess
A Marquess is a hereditary peer, and the highest rank of nobility outside of the royal family.

Earl
Earls were traditionally the rulers of the various Counties and represents someone who is ranked above a Baron but below a Marquess. Most of the Earldoms in the Kingdom were given to friends of King James I of Wintanceastre.

Baron
Barons are the lowest form of nobility who are permitted to sit in the Upper House of Parliament. Baronies are most commonly granted to notable members of the Wintanceastrean public - such as a former Prime Ministers.

Baronet
A Baronet is a hereditary knight. It is not a peerage, and Baronets are not considered "true nobles", however they outrank all other knights.

Knight
Knighthoods are granted to individuals who have excelled in varying fields, such as contributions to Wintanceastrean culture, either at the discretion of the King or on the advice of the Prime Minister. Usually around 10 people per year receive Knighthoods.

[Longweather]

The Imperial Dominion has two sets of ranks for nobility, one for the noble Houses and one for the government. The titles for the noble Houses can differ in name for the lower ranks but they're just alternative names.

Governmental Titles

-Emperor/Empress: The head of government of the Imperial Dominion. The Emperor/Empress generally has their hands in most of the government though they seldom take a very active role in all of it. What they do actively participate in varies between rulers. The consort of the Emperor/Empress also get this title though they are slightly lower in stature to their spouse. The Emperor/Empress by succession also carries various titles relating to "leading" the various branches of the government.
-Archon: Gender-neutral title of the main adviser(s) of the Emperor. They generally hold sway over much of the day-to-day running of the Empire and give advice to the Emperor/Empress when needed.

-Prince/Princess: Younger siblings of the Crown Prince/Princess. Not used if the heir has no siblings. Generally given a modest position in the government or military.
-Orator Prince/Princess: A member of the Orator Court, one of the three houses of legislature. The Orators (the proper plural) are the representatives of the High Houses of the Empire. They are chosen by their House to petition for a seat on the Orator Court so that the House can be or continue to be a High House. A majority vote amongst the currently seated Orators is required for a candidate to get a seat. Due to its nature the Orator Court deals with the laws and regulations regarding Houses, their position, what they can do, and settle disputes between the themselves and/or the commoners.
-Dominus/Domina: The title for the noble ruler of a Dominion World or Colony. They are high members of the peerage and get a seat on the Council of Lords. This branch of the government deals with inter-planetary/colony relations in the Empire as well as general foreign relations.
-Duke/Duchess: The title for the noble ruler of a Province on a Dominion World. They are mid-level members of the peerage and get a seat on the Council of Lords, representing themselves and the Masters/Mistresses below them. They are differentiated from House Dukes/Duchess' by having their domain mentioned in their title. For example, Duke Jakob Stonecaller of Serenity.
-Master/Mistress: The title for the noble ruler of a major city or metropolitan area, plus their surroundings, in a Province. They are low-level members of the peerage and generally act as the mayor of the realm.
-Knight of Victory: The gender-neutral title of a member of the Order of Immaculate Victory, the only officially sanctioned chivalric order in the Empire. Members are not necessarily noble by birth but become noble in stature. Their status of nobility does not extend to their spouse and heir/children if the holder is not of noble birth.
-Lord/Lady Senator: Title for a member of the Imperial Senate. A democratically elected title, commoners can be elected to this position for their provincial region and have full noble stature for as long as they can hold it. There are no term limits and the status of nobility does not extend to family members for commoners. The Imperial Senate drafts and votes for the laws that effect the Empire on a federal level.
-Lord/Lady Councillor: Title for a member of a Planetary/Colonial Council. A democratically elected title, commoners can be elected to this position for their provincial region and have full noble stature for as long as they can hold it. There are no term limits and the status of nobility does not extend to family members for commoners. The Imperial Senate drafts and votes for the laws that effect the Dominion World or Colony they are based on.
-Justice: The gender-neutral title for a member of the Imperial Court. They judge whether laws, resolutions, and decisions passed by the three legislatures are just and legal based upon the Articles of Empire, the founding document of the Imperial Dominion. They also judge trials against the nobility, government, and dark mages.
-High Priestess: The title for the priestess that leads the Empire's official religion, the Church of Thesse. A political and religious title, she offers her advice and opinions on all subjects and how they would work with the Church's teachings.



House Titles

-Matriarch/Patriarch: The head of a noble House and their spouse. In the case of same-sex couples, the spouse is the Matriach's/Patriach's-Consort. The head of the House is called the Lord/Lady [House Name] unless they're of a High House in which they're formally called the High Lord/Lady [House Name].
-Archduke/Archduchess: Special title for House Longweather, the House that founded and sits on the Imperial throne. Only given to the heir of the Matriarch/Patriarch which is always the Emperor/Empress.
-Duke/Duchess: Title for the highest ranking members of a noble House. They're often the children of the Matriarch/Patriarch or the more illustrious members of the House. These nobles are privy to the important dealings of their House. They are differentiated from the governmental Dukes/Duchess' by having their House mentioned in their title. For example, Duchess Califica Moonstrider of House Stormfallen.
-Count/Countess: Title for the middle ranking members of a noble House. They're occasionally privy to important dealings of the House if they have experience in them.
-Baron/Baroness: Title for the lowest ranking members of a noble House. They are still noble but don't have much going for them. They often are put in charge of things the higher members of the House don't want to be bothered with.
-Sir/Dame: Wealthy commoners who have tied their fortunes/wealth/destiny with that of a noble House. They often hope to marry into the House to elevate themselves. While not exactly nobles, they are treated as such by other commoners due to their ties while the nobles treat them slightly better than commoners.

[Allancia]

During the ages of the Kingdom of Allancia and the Church of Allancia, there was the same nobility system. However, both governments have become extant, so this ranking system is now outdated. Nevertheless, the systems has been recorded and is still kept today for historical reasons (Original Allancian put into parentheses):

-Emperor (Reichskaiser)
-King (Kaiser)
-Lord (Lauden)
-Baron (Barkonanz)
-Duke (Duzant)
-Count (Cantzen)
-Mayor (Burgrant)

[Elesri]

Prince/Princess-Regent: Ruler of our nation
Duke/Duchess:
Count/countess:
Knight: An honorary title often given to deserving commoners which allows them to be considered amongst the lowest ranks of the nobility.

The children of the Prince are given the title of count/countess and the designated heir is given the title of Duke/Duchess. In polite society the Prince is referred to as Your Royal Highness. Dukes and Counts are referred to as Lord/Lady and Knights as Sir/Madam.

[Tyrandel]

Retconned

Tyrandel has quite a few systems of Nobility, some extremely complex and others very simply.

The simplest are the nobility of the Imperial Territories. The nobles of the Imperial Territories are effectively warlords.

Emperor: Ruler of both Imperial Territories and commander of the Imperial Legions.
Consul: Ruler of a single Imperial Territory and associated Imperial Guards.
Castellan: Commander of a castle and its assigned group of Imperial Guards.

Slightly more complex is the Confederation of Princes, ruled by various different types of Merchant Prince.

Sarrum: The Sarrum, or Emperor, is the suzerain of the Confederation.
Rubutum: The highest noble is the Rubutum, or Grand Prince. The Grand Prince is whoever rules over the largest city.
Malkum: A Malkum, or Prince (in the HRE sense), rules over any other city.
Sirum: A Sirum, or City Lord (contrasted with the mere Lords who rule the countryside), is the overseer of a city district. They are generally only seen in the largest of cities and are wholly subordinate to the Malkum of their city.
Belum: Refers to the leaders of the various Guilds of the Trade Authority. Completely outside any city hierarchy, elected by the guild's membership, and answerable only to the Rubutum.
Mallahum: Owner and captain of one of the Trade Authority's freighters or flagships (the distinction is blurry). Answers to the Belum of their Guild but has a very high degree of autonomy.
Libitum: Captain of an escort vessel or lesser cargo ship. Usually subordinate to a Mallahum.

The nobility of Akaveonarveen is the oldest in Tyrandel and the closest to the Middle Age's nobility in organization, to the point it shares the same names in English. It is not however perfectly identical to any single human system.

King/Queen: Overall ruler of Akaveonarveen. Actually quite weak politically through a combination of Noble plotting and Confederate sabotage.
Crown Prince/Princess: Next in line for the throne.
Prince/Princess: Any child of the King/Queen. Bastardry is not a recognized concept with all offspring being considered legitimate, as marriage itself is also not a recognized concept.
Duke/Duchess: Ruler of a Duchy. Vassal of King/Queen.
Marquis/Marchioness: Assists Duke/Duchess in running Duchy. Often acts in a military capacity. Usually related to their commanding Duke/Duchess.
Count/Countess: Ruler of a County. Vassal of a Duke/Duchess.
Viscount/Viscountess: Assists Count/Countess in running County. Often acts in a judicial capacity. Usually related to their commanding Count/Countess.
Baron/Baroness: Ruler of a Barony. Vassal of a Count/Countess.
Baronet/Baronetess: Assists Baron/Baroness in running Barony. Often acts in a law enforcement capacity. Usually related to their commanding Baron/Baroness.

The Saseriff Despotate, unlike Akaveonarveen, possesses a Nobility appointed based on the whims of the overall ruler rather than a system of heredity.

Despot: The supreme ruler of the Saseriff Despotate and the central province.
Tyrant: Sovereign over one of the three non-central interior provinces.
Archon: Ruler of a border province.

The Dominion of the Wyrm is controlled by the Wyrmic Priests. It is relatively disorganized and possesses no unified infrastructure.

The Buzarkt Unity has is ruled by Shamans, essentially powerful Magi. There is no real organized hierarchy, stronger Shamans naturally being able to force their will upon weaker Shamans just as Shamans in general can force their will upon non-Shaman Buzarkt.

The Coalition of Jade is controlled by warlords who, unlike the Imperials, hold no fallacies about being some sort of glorious aristocracy. The average ruler is simply titled 'Warlord', the overall leader being 'Warmaster'.

[Fin Dovah Junaar]

Hierarch - Paarthurnax, Grand Hierarch of the land, controls the country though his sheer dominance and power, usually lets the Emperor, the Upper House of Kings, and Lower House of Commons handle everything else.
Emperor/Empress - Currently Emperor Alleon Gaius and Empress Cornelia Gaius, have full control and power over the nation, are only subservient to the Hierarch, who is rather calm and takes upon and act of nonintervention for most of all cases.
King/Queen - Control regions of the Empire.
Prince/Princess - Sons/Daughters of an Emperor/Empress or King/Queen, no true political power or ownership, but respect granted above others.
Duke/Duchess - Governors of a territory.
Count/Countess - Leaders of sections
Jarl - Owners of a city, carried over remnants of the old world.
Thane - Similarly a left over, simply a noble who ensures the Jarls will is taken seriously within the city, and handles security details.
Knight - Lowest of the nobles (Excluding Dragon Knights, who answer only to the Emperor and above) they are a warrior caste, and surprisingly are attuned to poetry and arts.

[Heco]

Even after the death of the monarchy there are still nobility ranks.

Duke
Lord
Count

The rest were abolished.
