The title 'Grand Duke' (in Latin, ''Magnus Dux''; in Spanish, ''Gran Duque''; in Russian, ''Великий князь''; in German, ''Großherzog'', Italian ''Gran Duca''; in French, ''Grand-duc''; in Portuguese, ''Grão-duque''; in Finnish, ''Suurherttua''; in Polish, ''Wielki Książę''; in Hungarian, ''nagyherceg'';in Swedish, ''Storhertig''; in Dutch, ''Groothertog''; in Danish, ''Storhertug'', in Lithuanian, ''Didysis Kunigaikštis'') used in Western Europe and particularly in Germanic countries for provincial sovereigns, is of a protocolary rank below King but higher than a sovereign Duke (''Herzog'') or ''Fürst'' (usually but confusingly translated as "Prince").
The feminine form is Grand Duchess. A Grand Duke's principality (state or merely titular) is called a Grand Duchy.
Grand Duke is the usual and established translation of Grand Prince in languages which do not have separate words meaning prince for (1) children of a monarch, and (2) monarch (sovereign or like) princes. English and French use Grand Duke also in this way.
The title Grand Duke as translation of 'Grand Prince' and the proper title 'Grand Duke' have clearly different meanings and a separate background. Compare with the article Grand Prince.

Western Grand Dukes

:''See also Grand Duchy''
The proper term of Grand Duke was a later invention, probably originating in Western Europe, to denote a particularly mighty duke, as the title Duke has until the end of Middle Ages been deflated to belong to rulers of relatively small fiefs (such as a city state or a district), instead of the big provinces it once was attached to.
One of the first examples was the semi-official use of Grand Duke meaning the later Dukes of Burgundy, i.e in 15th century, when they ruled a portion of East France as well as most of the Netherlands. Philip III, Duke of Burgundy (ruler 1419-67) assumed the subsidiary, legally void style and title 'Grand Duke of the West' in 1435, having recently consolidated duchies of Brabant and Limbourg as well as the countships of Holland, Zeeland, Friesland, Hainaut and Namur under his possession. His son and successor Charles the Bold (ruler 1467-77) continued to use the same style.
Apparently the first monarchs ever officially titled Grand Duke were the Medici sovereigns of Tuscany beginning from the late 16th century. This official title was granted by Pope Pius V in 1569, but the lands in question apparently belonged under the vassalage of the Holy Roman Empire.
Napoleon used to award that title extensively: during his era, several of his allies were allowed to assume the title of Grand Duke, usually at the same time as their inherited fiefs were enlarged by additional lands obtained thanks to being allies of Napoleon I of France. His conquerors, for example the Congress of Vienna, consented to yet more uses of the title. Thus, the 19th century saw a new group of monarchs titled Grand Duke all around Central Europe. A list of such is available at Grand Duchy.
At the same century, the courtesy use of translated Grand Duke, Russia, expanded because of births of several male dynasts, instead of the earlier precarious situations when Russia barely had only one or two to succeed.
The term can be said to originate in Germany, in a sense that a ruler in the then Germany's western borders was the first to be called so, and that it was a German overlord, the Holy Roman Emperor, whose vassal (however, an Italian) was first granted the official title, however, by the Pope.
The German and Dutch languages, which have separate words for royal prince (''Prinz, Prins'') and for sovereign prince (''Fürst, Vorst''), mark the Grand Princes of Lithuania, Russian states and other Eastern European as higher princes, as well as the Russian rulers and later princes of the blood, by the terms ''Grossfürst, Grootvorst'', not ''Grossherzog, Groothertog''.
The title ''Magnus Dux'' or Grand Duke (''Didysis kunigaikštis'' in Lithuanian) is said to have been used by the rulers of Lithuania, and after Jagiello also became kings of Poland. From 1573, both the Latin and the Polish equivalent ''Wielki Ksiaze'', in chief of Lithuania as well as Russia, Prussia, Mazovia, Samogithia, Kiev, Volhynia, Podolia, Podlachia, Livonia, Smolensk, Severia and Chernigov (including hollow claims), were used as part of the respective versions of the full style officially used by the kings (title ''Krol'') of Poland during the Polish-Lithuanian Commonwealth. The Polish kings of the Swedish Vasa dynasty also used the grand-princely title for their non-Polish territory.
In 1582 king John III of Sweden added Grand Duke of Finland to the subsidiary titles of the Swedish kings, however without any factual consequences, Finland already being a part of the Swedish realm.
After the Russian conquests, it continued to be used by the Russian Emperor in his role as ruler of Lithuania (1793-1918) and of autonomous Finland (1809-1917) as well. The Holy Roman Empire ruling house of Habsburg instituted a similar Grand Principality in Transylvania in 1765.

Grand Prince

Main articles: Grand Prince

Grand Princes or ''great princes'' were medieval monarchs who ruled usually several tribes and/or were overlords of other princes. At the time, they were usually treated and translated as kings. However, grand princes were not as elevated sovereign as later Western kings, and perhaps thus they are treated lower than kings, particularly in later literature.
Grand Princes ruled in Central and Eastern Europe, notably among Slavs, Balts and Hungarians.
The title ''Grand Prince'' is ''Velikiy Knjaz'' (''Великий князь'') in Russian. The Slavic word ''knjaz'' and the Baltic ''kunigaitis'' (today translated as Prince) are actually cognates of King. Thus, ''Veliki Knjaz'' was more like "high king" than "grand duke".
These countries developed in a way that the position of the head of the dynasty became more elevated. In such situations, those Monarchs assumed a higher title, such as Tsar or sole King. Grand Prince Ivan IV of Muscovy was apparently the last monarch to rule without any higher title, until he assumed the style Tsar of Russia in 1547.
The title Grand Prince (which in many of those lands already was in later medieval centuries awarded simultaneously to several rulers of the more expanded dynasty) continued, in modern times, as a courtesy title for all or several members of the Russian dynasty, such as the Grand Duke of Russia (''veliki knjaz'') in Russia's imperial era.

Byzantine Grand Dukes

The Latin title ''dux'' (the etymological root of duke), which was phonetically rendered ''δουξ'' in Greek, was a common title for imperial generals in the Late Roman Empires (west and east), but note it was ''lower'' in rank than ''Comes'' (the etymological root of Count). In the Eastern Empire, a ''dux'' ranked just below a strategos.
Under the later, exclusively Byzantine theme system (the new military circonscriptions, becoming more important than the provinces), the commander of a theme was styled a dux.

★ The title ''Megas Doux'', or in latinized spelling ''Megas Dux'' ( Μέγας Δουξ), literally 'Grand duke' (''Megas'' being the Greek for great, used in front of various styles), occasionally anglicised ''Megaduke'', first appears in the Comnenian period, and was conferred upon the commanding admiral of the Byzantine navy, used in the Byzantine Empire during the Palaeologian dynasty (1259-1453). Among the recipients of this honor was Roger de Flor of the Catalan Company, who was given the title for his services against the Turks during the reign of Andronicus II Palaeologus.
By the time Constantinople fell to the Ottoman Turks, the office had become virtual chief minister, heading both civil and military administration.

Russian Grand Dukes

:''for a fuller account, see Grand Prince''
"Grand Duke" is the traditional translation of the title ''Velikiy Kniaz'', which from the 11th century was at first the title of the leading Prince of Kievan Rus', then of several princes of the Rus'. From 1328 the ''Velikii Kniaz'' of Muscovy appeared as the Grand Duke for "all of Russia" until Ivan IV of Russia in 1547 was crowned as Tsar. Thereafter the title was given to sons and grandsons (through male lines) of the Tsars and Emperors of Russia. The daughters and paternal granddaughters of Russian Emperors, as well as the consorts of Russian Grand Dukes, were generally called "Grand Duchesses" in English.
Another translation of the Russian title would be ''Grand Prince'' but the term is neither standard nor widely used in English. In German, however, a Russian Grand Duke was known as a ''Großfürst'', and in Latin as ''Magnus Princeps''.
From 1809 to 1917 the Emperor of Russia was also the Grand Duke of Finland, which he held as an autonomous state. Before the Russian conquest Finland had been held by the Swedish kings, first as a royal duchy, since 1581 with the King assuming the secondary title Grand Prince of Finland (Finnish: ''Suomen suuriruhtinas'', Swedish: ''Storfurste av Finland''), also often translated as Grand Duke of Finland.

Styles

Tuscany's sovereign obtained in 17th century the status of Royal Highness.
Most often, a reigning Grand Duke or Duchess was styled ''Royal Highness''. Other members of the families differed in style. Junior members of the Grand Ducal Family of Luxembourg are also ''Royal Highnesses''; however, this derives from their status apparently as cadet members of the dethroned royal house of Bourbon-Parma and not from the Grand Ducal title.
In Hesse-Darmstadt and Baden, however, junior members of the ruling dynasty bore the style of ''Grand Ducal Highness'' (''Großherzogliche Hoheit''). For instance, prior to her marriage, Empress Alexandra of Russia was known as "Her Grand Ducal Highness Princess Alix of Hesse and by the Rhine" (''Ihre Großherzogliche Hoheit Alix Prinzessin von Hessen und bei Rhein'').
A Russian Grand Duke or Grand Duchess was an ''Imperial Highness''.
