Commander (Italian: Commendatore, French: Commandeur, German: Komtur, Spanish: Comandante, Portuguese: Comendador), or Knight Commander, is a title of honor prevalent in chivalric order and fraternal orders.
The title of Commander occurred in the medieval military orders, such as the Knights Hospitaller, for a member senior to a Knight. Variations include Knight Commander, notably in English, sometimes used to denote an even higher rank than Commander. In some orders of chivalry, Commander ranks above Officier (i.e. Officer), but below one or more ranks with a prefix meaning "Great", e.g. Grand - in French, Grosskomtur in German, Comandante Mayor (using an equivalent suffix) in Spanish, and Groot- in Dutch (Grootcommandeur; "Grand Commander"), Grand Cross.
The rank of commandeur in the French orders comes from the Middle Ages military orders, in which low-level administrative houses were called commanderies and were governed by commandeurs. In the Modern Age, the French Kings created chivalric orders which mimicked the military order's ranks.
Both orders were suppressed in 1830 by the new King Louis-Philippe I.
The official title of Commendatore, literally equivalent to the English Knight Commander, is awarded by decree of the President of Italy to individuals who are given this honour in the Order of Merit of the Italian Republic and other orders of knighthood. The Commendatore, or Knight Commander, rank is a higher award than that of "Ufficiale" (Officer), which in turn is higher than the first level of "Cavaliere" (Knight) in this order of chivalry, which was originally established in Italy by the Royal House of Savoy. The Italian government's orders are exceptional to the international standard in that they do not officially have special ranks or decorations for females (Dames).
The rank of Commendatore is also bestowed in several Italian dynastic orders of the royal houses of Savoy, the Two Sicilies, Parma and Tuscany. The Republic of Italy officially recognizes the Orders and titles conferred upon its citizens from the Holy See and from some of the royal houses of Italy.
Commendatore is also the Italian translation for the rank of Knight Commander in foreign orders, such as the Order of the British Empire.
Il Commendatore is also a character in Mozart's Don Giovanni, and was additionally commonly used to refer to Enzo Ferrari. In the movie The Godfather: Part III, Michael Corleone is addressed as "Commendatore" Michael Corleone on his return to Sicily since he received a Papal order of knighthood.
In German, Komtur (derived from Latin: commendator) was a rank within military orders, especially the Teutonic Knights. In the State of the Teutonic Order, the Komtur was the commander of a basic administrative division called Kommende (also Komturei). A Komtur was responsible for feeding and supporting the Order's Knights from the yield of local estates. He commanded several Procurators. A Kommende had a convent of at least 12 brothers. Various Kommenden formed a Ballei province.
Grosskomtur (Großkomtur or Grand Commander) was one of the highest ranks within the Knights responsible for the administration of the Order and second-in-command after the Grand Master. He had his seat at Malbork Castle (Marienburg). Grosskomtur and four other senior officers like the Grand Marshal were appointed by the Grand Master and formed the council of Großgebietiger with competence on the whole order.
In postwar Germany the ranks of the Order of Merit were named totally with new terms. The equivalent to a commander is the Great Cross of Merit and the Knight Commander's equivalent is the Great Cross of Merit with the Star and Slash (Großes Verdienstkreuz mit Stern und Schulterband)
As for the Papal orders, it is also applied in the Sovereign Military Order of Malta (in its Order pro merito Melitensi bestowed for merit) and the Order of the Holy Sepulchre. Traditionally, the analogous rank for ladies is Dama di Commenda ("Dame commander"), but today the word "Commendatrice" is sometimes used.
United Kingdom is distinguished by its use of differentiating Commander and Knight or Dame Commander.
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 Commonwealth Realms orders and decorations, Knight Commander and Dame Commander rank before Knights Bachelor but after the Order of the Companions of Honour, although Companions of Honour obtain no knighthood or other status.
In the Royal Victorian Order and the Order of the British Empire, the grade of Commander is senior to the grade of Lieutenant or Officer respectively, but junior to that of Knight Commander or Dame Commander. In the British Venerable Order of Saint John, a Commander ranks below a Knight. However, Knights of the Venerable Order of St John are not entitled Sir.
The orders that award the rank of Knight Commander, and related post-nominal letters, are as follows (dormant orders in italics):
Knights Commander and Dames Commander rank behind the most senior rank in each order, that of Knight 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.
In military orders with extensive territorial possessions, individual estates could be called commenda and enthrusted to an individual knight, as a de facto fief. Apart from cases where such a fief was ex officio linked to a higher office within the order, his style would then be Commandeur; this etymology is best preserved in the Spanish form Commendador, important in the military orders involved in the Reconquista such as the Order of Santiago.
