Knight Commander (or Dame Commander) is the second most senior grade of seven British orders of chivalry, three of which are dormant (and one of them continues as a German house order). The rank entails admission into knighthood, allowing the recipient to use the title 'Sir' (male) or 'Dame' (female) before his or her name. In the British system of precedence, Knights (and Dames) Commander rank after the Order of the Companions of Honour (although Companions of Honour obtain no knighthood or other status) and before Knights Bachelor.
The Orders that award the rank of Knight Commander, and related post-nominal letters, are (dormant orders in italics):
Knights (and Dames) Commander rank behind the most senior rank in each order, that of Knights Grand Cross. The third most senior rank in each order is a Companion (CB, CSI, CMG, CIE), Knight (KH) or Commander (CVO, CBE). Insignia include a breast star, a badge, and a ribbon.
It is also a grade in the orders of other countries, such as the Order of St. Gregory the Great. The Italian equivalent is Commendatore.
A knight is a person granted an honorary title of knighthood by a head of state or representative for service to the monarch, the church or the country, especially in a military capacity.
In the United Kingdom and the British Overseas Territories, personal bravery, achievement, or service are rewarded with honours. The honours system consists of three types of award:
The Most Excellent Order of the British Empire is a British order of chivalry, rewarding contributions to the arts and sciences, work with charitable and welfare organizations, and public service outside the civil service. It comprises five classes of awards across both civil and military divisions, the most senior two of which make the recipient either a knight if male or a dame if female. There is also the related British Empire Medal, whose recipients are affiliated with, but not members of, the order.
Sir is a formal honorific address in English for men, derived from Sire in the High Middle Ages. Both are derived from the old French "Sieur" (Lord), brought to England by the French-speaking Normans, and which now exist in French only as part of "Monsieur", with the equivalent "My Lord" in English.
The order of precedence in the United Kingdom is the sequential hierarchy for Peers of the Realm, officers of state, senior members of the clergy, holders of the various Orders of Chivalry, and is mostly determined, but not limited to, birth order, place in the line of succession, or distance from the reigning monarch. The order of precedence can also be applied to other persons in the three legal jurisdictions within the United Kingdom:
The Most Honourable Order of the Bath is a British order of chivalry founded by King George I on 18 May 1725. Recipients of the Order are usually senior military officers or senior civil servants, and the monarch awards it on the advice of His Majesty's Government. The name derives from an elaborate medieval ceremony for preparing a candidate to receive his knighthood, of which ritual bathing was an element. While not all knights went through such an elaborate ceremony, knights so created were known as "knights of the Bath".
The Most Distinguished Order of Saint Michael and Saint George is a British order of chivalry founded on 28 April 1818 by George, Prince of Wales, while he was acting as prince regent for his father, King George III. It is named in honour of two military saints, Michael and George.
The order of precedence in Scotland was fixed by Royal Warrant in 1905. Amendments were made by further Warrants in 1912, 1952, 1958, 1999 to coincide with the establishment of the Scottish Parliament and Scottish Government and most recently in 2012.
An unofficial order of precedence in Northern Ireland, according to Burke's Peerage, 106th Edition, this is not officially authorised by or published with authority from either Buckingham Palace or the College of Arms, or the Home Office, the Ministry of Justice or the Northern Ireland Office (NIO) of His Majesty's Government in the United Kingdom, or the Northern Ireland Assembly, or the Northern Ireland Executive.
The Royal Victorian Order is a dynastic order of knighthood established in 1896 by Queen Victoria. It recognises distinguished personal service to the monarch, members of the royal family, or to any viceroy or senior representative of the monarch. The present monarch, King Charles III, is the sovereign of the order. The order's motto is Victoria. The order's official day is 20 June. The order's chapel is the Savoy Chapel in London.
The title of Knight Bachelor is the basic rank granted to a man who has been knighted by the monarch but not inducted as a member of one of the organised orders of chivalry; it is a part of the British honours system. Knights Bachelor are the most ancient sort of British knight, but Knights Bachelor rank below knights of chivalric orders. A man who is knighted is formally addressed as "Sir [First Name] [Surname]" or "Sir [First Name]" and his wife as "Lady [Surname]".
The Most Exalted Order of the Star of India is an order of chivalry founded by Queen Victoria in 1861. The Order includes members of three classes:
Grand Cross is the highest class in many orders, and manifested in its insignia. Exceptionally, the highest class may be referred to as Grand Cordon or equivalent. In other cases, there may exist a rank even higher than Grand Cross, e.g. Grand Collar. In rare cases, the insignia itself is referred to as the "grand cross".
The orders, decorations, and medals of Canada comprise a complex system by which Canadians are honoured by the country's sovereign for actions or deeds that benefit their community or the country at large. Modelled on its British predecessor, the structure originated in the 1930s, but began to come to full fruition at the time of Canada's centennial in 1967, with the establishment of the Order of Canada, and has since grown in both size and scope to include dynastic and national orders, state, civil, and military decorations; and various campaign medals. The monarch in right of each Canadian province also issues distinct orders and medals to honour residents for work performed in just their province. The provincial honours, as with some of their national counterparts, grant the use of post-nominal letters and or supporters and other devices to be used on personal coats of arms.
An order of chivalry, order of knighthood, chivalric order, or equestrian order is an order of knights, typically founded during or inspired by the original Catholic military orders of the Crusades and paired with medieval concepts of ideals of chivalry.
Dame is an honorific title and the feminine form of address for the honour of damehood in many Christian chivalric orders, as well as the British honours system and those of several other Commonwealth realms, such as Australia and New Zealand, with the masculine form of address being Sir. It is the female equivalent of a knighthood, which is traditionally granted to males. Dame is also a style used by baronetesses in their own right.
Commander, or Knight Commander, is a title of honor prevalent in chivalric orders and fraternal orders.
A collar, also known as collar of an order, is an ornate chain, often made of gold and enamel, and set with precious stones, which is worn about the neck as a symbol of membership in various chivalric orders. It is a particular form of the livery collar, the grandest form of the widespread phenomenon of livery in the Middle Ages and Early Modern Period. Orders which have several grades often reserve the collar for the highest grade. The links of the chain are usually composed of symbols of the order, and the badge of the order normally hangs down in front. Sometimes the badge is referred to by what is depicted on it; for instance, the badge that hangs from the chain of the Order of the Garter is referred to as "the George".
The orders, decorations, and medals of the Holy See include titles, chivalric orders, distinctions and medals honoured by the Holy See, with the Pope as the fount of honour, for deeds and merits of their recipients to the benefit of the Holy See, the Catholic Church, or their respective communities, societies, nations and the world at large.
The Central Chancery of the Orders of Knighthood has, at irregular intervals, notified for general information the positioning of the wearing of Orders, decorations, and medals of the United Kingdom in the London Gazette. The Order of Wear was last published in 2019.
