Tsar ( /zɑːr, sɑːr/ or /tsɑːr/ ; Old Church Slavonic: ц︢рь [usually written thus with a title] or цар, царь), also spelled czar, or tzar, is a title used to designate East and South Slavic monarchs or supreme rulers of Eastern Europe, originally Bulgarian monarchs from 10th century onwards. As a system of government in the Tsardom of Russia and the Russian Empire, it is known as Tsarist autocracy, or Tsarism. The term is derived from the Latin word Caesar , which was intended to mean "Emperor" in the European medieval sense of the term—a ruler with the same rank as a Roman emperor, holding it by the approval of another emperor or a supreme ecclesiastical official (the Pope or the Ecumenical Patriarch)—but was usually considered by western Europeans to be equivalent to king, or to be somewhat in between a royal and imperial rank.

Old Church Slavonic Medieval Slavic literary language

Old Church Slavonic or Old Slavonic, also known as Old Church Slavic or Old Slavic, was the first Slavic literary language. It is also referred to as Paleo-Slavic (Paleoslavic) or Palaeo-Slavic (Palaeoslavic), not to be confused with the Proto-Slavic. It is often abbreviated to OCS.

Titlo diacritical mark

Titlo is an extended diacritic symbol initially used in early Cyrillic manuscripts, e.g., in Old Church Slavonic and Old East Slavic languages. The word is a borrowing from the Greek "τίτλος", "title". The titlo still appears in inscriptions on modern icons and in service books printed in Church Slavonic.

A monarch is a sovereign head of state in a monarchy. A monarch may exercise the highest authority and power in the state, or others may wield that power on behalf of the monarch. Typically a monarch either personally inherits the lawful right to exercise the state's sovereign rights or is selected by an established process from a family or cohort eligible to provide the nation's monarch. Alternatively, an individual may become monarch by conquest, acclamation or a combination of means. A monarch usually reigns for life or until abdication.


"Tsar" and its variants were the official titles of the following states:

First Bulgarian Empire medieval Bulgarian state that existed in southeastern Europe between the 7th and 11th centuries AD

The First Bulgarian Empire was a medieval Bulgarian state that existed in Southeastern Europe between the 7th and 11th centuries AD. It was founded in 681 when Bulgar tribes led by Asparuh moved to the northeastern Balkans. There they secured Byzantine recognition of their right to settle south of the Danube by defeating – possibly with the help of local South Slavic tribes – the Byzantine army led by Constantine IV. At the height of its power, Bulgaria spread from the Danube Bend to the Black Sea and from the Dnieper River to the Adriatic Sea.

Second Bulgarian Empire medieval Bulgarian state

The Second Bulgarian Empire was a medieval Bulgarian state that existed between 1185 and 1396. A successor to the First Bulgarian Empire, it reached the peak of its power under Tsars Kaloyan and Ivan Asen II before gradually being conquered by the Ottomans in the late 14th and early 15th centuries. It was succeeded by the Principality and later Kingdom of Bulgaria in 1878.

Serbian Empire former country

The Serbian Empire is a historiographical term for the empire in the Balkan peninsula that emerged from the medieval Serbian Kingdom. It was established in 1346 by King Stefan Dušan, known as "the Mighty", who significantly expanded the state. Under Dušan's rule Serbia was the major power in the Balkans, and a multi-lingual empire that stretched from the Danube to the Gulf of Corinth, with its capital in Skopje. He also promoted the Serbian Archbishopric to the Serbian Patriarchate. His son and successor, Uroš the Weak, lost most of the territory conquered by Dušan, hence his epithet. The Serbian Empire effectively ended with the death of Uroš V in 1371 and the break-up of the Serbian state. Some successors of Stefan V claimed the title of Emperor in parts of Serbia until 1402, but the territory in Greece was never recovered.

The first ruler to adopt the title tsar was Simeon I of Bulgaria. [2] Simeon II, the last Tsar of Bulgaria, is the last person to have borne the title Tsar.

Simeon I of Bulgaria King of the Bulgarians

SimeonI the Great ruled over Bulgaria from 893 to 927, during the First Bulgarian Empire. Simeon's successful campaigns against the Byzantines, Magyars and Serbs led Bulgaria to its greatest territorial expansion ever, making it the most powerful state in contemporary Eastern Europe. His reign was also a period of unmatched cultural prosperity and enlightenment later deemed the Golden Age of Bulgarian culture.

Simeon II of Bulgaria is the last reigning Bulgarian monarch and later served as Prime Minister of Bulgaria from 2001 to 2005.

Meaning in Slavic languages

The title Tsar is derived from the Latin title for the Roman emperors, Caesar. [3] In comparison to the corresponding Latin word "imperator", the Byzantine Greek term basileus was used differently depending on whether it was in a contemporary political context or in a historical or Biblical context. In the history of the Greek language, basileus had originally meant something like "potentate". It gradually approached the meaning of "king" in the Hellenistic Period, and it came to designate "emperor" after the inception in the Roman Empire. As a consequence, Byzantine sources continued to call the Biblical and ancient kings "basileus" even when that word had come to mean "emperor" when referring to contemporary monarchs (while it was never applied to Western European kings, whose title was transliterated from Latin "rex" as ῥήξ, or to other monarchs, for whom designations such as ἄρχων "leader", "chieftain" were used).


Basileus is a Greek term and title that has signified various types of monarchs in history. In the English-speaking world it is perhaps most widely understood to mean "king" or "emperor". The title was used by sovereigns and other persons of authority in ancient Greece, the Byzantine emperors, and the kings of modern Greece.

Roman Empire period of Imperial Rome following the Roman Republic (27 BC–395 AD)

The Roman Empire was the post-Roman Republic period of the ancient Roman civilization. It had a government headed by emperors and large territorial holdings around the Mediterranean Sea in Europe, North Africa, and West Asia. From the constitutional reforms of Augustus to the military anarchy of the third century, the Empire was a principate ruled from the city of Rome. The Roman Empire was then divided between a Western Roman Empire, based in Milan and later Ravenna, and an Eastern Roman Empire, based in Nicomedia and later Constantinople, and it was ruled by multiple emperors.

As the Greek "basileus" was consistently rendered as "tsar" in Slavonic translations of Greek texts, the dual meaning was transferred into Church Slavonic. Thus, "tsar" was not only used as an equivalent of Latin "imperator" (in reference to the rulers of the Byzantine Empire, the Holy Roman Empire and to native rulers) but was also used to refer to Biblical rulers and ancient kings.

Church Slavonic language Liturgical language of the Orthodox Church in Russia, Ukraine and Belarus

Church Slavonic, also known as Church Slavic, New Church Slavonic, or New Church Slavic, is the conservative Slavic liturgical language used by the Orthodox Church in Bulgaria, Russia, Belarus, Serbia, Montenegro, Bosnia and Herzegovina, North Macedonia, Ukraine, Poland, Czech Republic and Slovakia, Slovenia, and Croatia. The language appears also in the services of the American Carpatho-Russian Orthodox Diocese and occasionally in the services of the Orthodox Church in America. It was also used by the Orthodox Churches in Romanian lands until the late 17th and early 18th centuries, as well as by Roman Catholic Croats in the Early Middle Ages. It is also co-used by Greek Catholic Churches, which are under Roman communion, in Slavic countries, for example the Croatian, Slovak and Ruthenian Greek Catholics, as well as by the Roman Catholic Church.

From this ambiguity, the development has moved in different directions in the different Slavic languages. Thus, the Bulgarian language and Russian language no longer use tsar as an equivalent of the term emperor/imperator as it exists in the West European (Latin) tradition. Currently, the term tsar refers to native sovereigns, ancient and Biblical rulers, as well as monarchs in fairy tales and the like. The title of king (Russian korol' , Bulgarian kral- the origin of which is Charlemagne (Karl)) is sometimes perceived as alien and is by some Russian-speakers reserved for (West) European royalty (and, by extension, for those modern monarchs outside of Europe whose titles are translated as king in English, roi in French etc.). Foreign monarchs of imperial status, both inside and outside of Europe, ancient as well as modern, are generally called imperator (император), rather than tsar.

Bulgarian language South Slavic language

Bulgarian, is an Indo-European language and a member of the Southern branch of the Slavic language family.

Russian language East Slavic language

Russian is an East Slavic language, which is official in the Russian Federation, Belarus, Kazakhstan and Kyrgyzstan, as well as being widely used throughout Eastern Europe, the Baltic states, the Caucasus and Central Asia. It was the de facto language of the Soviet Union until its dissolution on 25 December 1991. Although, nowadays, nearly three decades after the breakup of the Soviet Union, Russian is used in official capacity or in public life in all the post-Soviet nation-states, as well as in Israel and Mongolia, the rise of state-specific varieties of this language tends to be strongly denied in Russia, in line with the Russian World ideology.

In contrast, the Serbocroatian language (which can also be viewed as different languages—Serbian, Croatian and Bosnian) translate "emperor" (Latin imperator) as tsar (car, цар) and not as imperator, whereas the equivalent of king (kralj, краљ, король) is used to designate monarchs of non-imperial status, Serbian as well as foreign ancient rulers—like Latin "rex". Biblical rulers in Serbian are called цар and in Croatian kralj.

In the modern West Slavic languages and Slovene language, the use of the terms is nearly identical to the one in English and German: a king is designated with one term (Czech král, Slovak kráľ, Polish król, Slovene kralj), an emperor is designated with another, derived from Caesar as in German (Czech císař, Slovak cisár, Polish cesarz, Slovene cesar; Croatian cesar and Montenegrin ćesar fell into disuse after World War I), while the exotic term "tsar" (Czech, Slovene and Polish car, Slovak cár) is reserved for the Bulgarian, Russian and Serbian rulers.

In the Polish language however tsar is used as an equivalent to imperator, never as king. The term tsar is always used to refer to the Russian rulers before Peter the Great, and very often to those succeeding.

Simeon Saxe-Coburg-Gotha is the only living person who (as Simeon II) has borne the title "Tsar".

In 705 Emperor Justinian II named Tervel of Bulgaria "Caesar", the first foreigner to receive this title, but his descendants continued to use Bulgar title "Kanasubigi". The sainted Boris I is sometimes retrospectively referred to as tsar, because at his time Bulgaria was converted to Christianity. However, the title "tsar" (and its Byzantine Greek equivalent "basileus") was actually adopted and used for the first time by his son Simeon I, following a makeshift imperial coronation performed by the Patriarch of Constantinople in 913. After an attempt by the Byzantine Empire to revoke this major diplomatic concession and a decade of intensive warfare, the imperial title of the Bulgarian ruler was recognized by the Byzantine government in 924 and again at the formal conclusion of peace in 927. Since in Byzantine political theory there was place for only two emperors, Eastern and Western (as in the Late Roman Empire), the Bulgarian ruler was crowned basileus as "a spiritual son" of the Byzantine basileus. [5]

Some of the earliest attested occurrences of the titlo-contraction "tsar" (car' ) from "tsesar" (cěsar' ) are found in the grave inscription of the chărgubilja (ichirgu-boil) Mostich, a contemporary of Simeon I and Peter I, from Preslav.

It has been hypothesized that Simeon's title was also recognized by a papal mission to Bulgaria in or shortly after 925, as a concession in exchange for a settlement in the Bulgarian-Croatian conflict or a possible attempt to return Bulgaria to union with Rome. Thus, in the later diplomatic correspondence conducted in 1199–1204 between the Bulgarian ruler Kaloyan and Pope Innocent III, Kaloyan—whose self-assumed Latin title was "imperator Bulgarorum et Blachorum"—claims that the imperial crowns of Simeon I, his son Peter I, and of Samuel were somehow derived from the Papacy. The Pope, however, only speaks of reges, kings of Bulgaria in his replies, and eventually grants only that lesser title to Kaloyan, who nevertheless proceeds to thank the Pope for the "imperial title" conferred upon him. [6]

The title, later augmented with epithets and titles such as autocrat to reflect current Byzantine practice, was used by all of Simeon's successors until the complete conquest of Bulgaria by the Ottoman Empire in 1422. In Latin sources the Emperor of Bulgaria is sometimes designated "Emperor of Zagora" (with variant spellings). Various additional epithets and descriptions apart, the official style read "Emperor and autocrat of all Bulgarians and Greeks".

During the five-century period of Ottoman rule in Bulgaria, the sultan was frequently referred to as "tsar". This may be related to the fact that he had claimed the legacy of the Byzantine Empire or to the fact that the sultan was called "Basileus" in medieval Greek.

After Bulgaria's liberation from the Ottomans in 1878, its new monarchs were at first autonomous prince (knjaz). With the declaration of full independence, Ferdinand I of Bulgaria adopted the traditional title "tsar" in 1908 and it was used until the abolition of the monarchy in 1946. However, these titles were not generally perceived as equivalents of "emperor" any longer. In the Bulgarian as in the Greek vernacular, the meaning of the title had shifted [7] (although Paisius' Slavonic-Bulgarian History (1760–1762) had still distinguished between the two concepts). Accordingly, while Ferdinand and his successors, Boris III and Simeon II, used the title of "tsar" in Bulgarian, they used the title of "king" outside Bulgaria. In the same fashion, the modern rulers of Greece (1821-1923, 1935-1973) used the traditional title of basileus in Greek and the title of "king" outside Greece.

Kievan Rus'

"Tsar"– was used once by Church officials of Kievan Rus' in the naming of Yaroslav the Wise of Kiev. This may be connected to Yaroslav's war against Byzantium and to his efforts to distance himself from Constantinople. However, other princes of Kievan Rus' never styled themselves as "czars". [8] After the fall of Constantinople to the Crusaders and the Mongol invasion of Rus' (1237–1240), the term "tsar" was applied by some people of Kievan Rus' to the Mongol (Tatar) overlords of the Rus' principalities.


Tsar Dusan of Serbia Serbian Emperor Stefan Dusan, cropped.jpg
Tsar Dušan of Serbia

The title of tsar (sr. "car") was used officially by two monarchs, the previous monarchial title being that of king (kralj). In 1345, Stefan Dušan began to style himself "Emperor of Serbs and Greeks" (the Greek renderings read "basileus and autokrator of Serbs and Romans"), and was crowned as such in Skopje on Easter (April 16) 1346 by the newly elevated Serbian patriarch, alongside the Bulgarian patriarch and archbishop of Ohrid. On the same occasion, he had his wife Helena of Bulgaria crowned as empress and his son associated in power as king. When Dušan died in 1355, his son Stefan Uroš V became the next emperor. The new emperor's uncle Simeon Uroš (Siniša) contested the succession and claimed the same titles as a dynast in Thessaly. After his death around 1370, he was succeeded in his claims by his son John Uroš, who retired to a monastery in about 1373.

With the extinction of the Nemanjić dynasty in Serbia in 1371, the imperial title became obsolete (though it was retained by Stefan Uroš IV's widow Elena of Bulgaria until her death in 1376/1377). The royal title was preserved by Vukašin Mrnjavčević, a Serbian ruler in Macedonia, who had been associated by Stefan Uroš. Several other Serbian rulers are known as tsars, although they were never recognized as such. These include Tsar Lazar (who was titled autokrator), Tsar Jovan Nenad (self-given) and Tsar Stephen the Little (who claimed to be the Russian Emperor in Montenegro).

During the five-century period of the Ottoman rule in Serbia, the sultan was also frequently referred to as tsar, for instance in Serbian epic poetry.


The first Russian ruler to openly break with the khan of the Golden Horde, Mikhail of Tver, assumed the title of "Basileus of Rus" and "czar". [9]

Władysław IV of Poland was the Tsar of Russia during the Time of Troubles, when the Polish forces occupied Moscow.

Following his assertion of independence from the khan, "Veliki Kniaz" Ivan III of Muscovy started to use the title of tsar Russian : Царь regularly in diplomatic relations with the West. From about 1480, he is designated as "imperator" in his Latin correspondence, as "keyser" in his correspondence with the Swedish regent, as "kejser" in his correspondence with the Danish king, Teutonic Knights, and the Hanseatic League. Ivan's son Vasily III continued using these titles. Sigismund von Herberstein observed that the titles of "kaiser" and "imperator" were attempts to render the Russian term "tsar" into German and Latin, respectively. [10]

This was related to Russia's growing ambitions to become an Orthodox "Third Rome", after the Fall of Constantinople. The Muscovite ruler was recognized as an emperor by Holy Roman Emperor Maximilian I in 1514. [11] [12] [13] However, the first Russian ruler to be formally crowned as Tsar of All Rus Russian : Царь Всея Руси) was Ivan IV, until then known as Grand Prince of all the Russias. Some foreign ambassadors—namely, Herberstein (in 1516 and 1525), Daniel Printz a Buchau (in 1576 and 1578) and Just Juel (in 1709)—indicated that the word "tsar" should not be translated as "emperor", because it is applied by Russians to David, Solomon and other Biblical kings, which are simple "reges". [14] On the other hand, Jacques Margeret, a bodyguard of False Demetrius I, argues that the title of "tsar" is more honorable for Muscovites than "kaiser" or "king" exactly because it was God and not some earthly potentate who ordained to apply it to David, Solomon, and other kings of Israel. [15] Samuel Collins, a court physician to Tsar Alexis in 1659-66, styled the latter "Great Emperour", commenting that "as for the word Czar, it has so near relation to Cesar... that it may well be granted to signifie Emperour. The Russians would have it to be an higher title than King, and yet they call David Czar, and our kings, Kirrols, probably from Carolus Quintus, whose history they have among them". [16]

In 1610 Sigismund III of Poland manipulated his son Władysław IV's election as tsar of Russia while Polish forces held Moscow during the Time of Troubles following the death of Boris Godunov. His election, which never resulted in his assumption of the Muscovite throne, was part of an unsuccessful plan by Sigismund to conquer all of Russia and convert the population to Catholicism. As a young man Władysław showed ability as a military leader in operations against Muscovy (1617–18) and the Ottoman Empire (1621). [17]

In 1670, Pope Clement X expressed doubts that it would be appropriate for him to address Alexis as "tsar", because the word is "barbarian" and because it stands for an "emperor", a title reserved for the Holy Roman Emperor. Abbot Scarlati's opined that the term is not translatable and therefore may be used by the Pope without any harm. In order to settle the matter and to assert his imperial ambitions more clearly, Peter I the Great issued an edict that raised Russia to an empire and decreed that the Latin title Imperator should be used instead of Tsar (1721).

The title tsar remained in common usage, and also officially as the designator of various titles signifying rule over various states absorbed by the Muscovite monarchy (such as the former Tatar khanates and the Georgian Orthodox kingdom). In the 18th century, it was increasingly viewed as inferior to "emperor" or highlighting the oriental side of the term. [18] Upon annexing Crimea in 1783, Catherine the Great adopted the hellenicized title of Tsaritsa of Tauric Chersonesos, rather than "Tsaritsa of the Crimea". By 1815, when a large part of Poland was annexed, the title had clearly come to be interpreted in Russia as the equivalent of Polish Król "king", and the Russian emperor assumed the title "tsar of Poland". [19]

Since the word "tsar" remained the popular designation of the Russian ruler despite the official change of style, it is commonly used in foreign languages such as English.

Metaphorical uses

Like many lofty titles, e.g. Mogul, Tsar or Czar has been used as a metaphor for positions of high authority, in English, since 1866 (referring to U.S. President Andrew Johnson), with a connotation of dictatorial powers and style, fitting since "Autocrat" was an official title of the Russian Emperor (informally referred to as 'the Tsar'). Similarly, Speaker of the House Thomas Brackett Reed was called "Czar Reed" for his dictatorial control of the House of Representatives in the 1880s and 1890s.

In the United States and in the UK the title "czar" is a slang term for certain high-level civil servants, such as the "drug czar" for the director of the Office of National Drug Control Policy (not to be confused with a drug baron), "terrorism czar" for a Presidential advisor on terrorism policy, "cybersecurity czar" for the highest-ranking Department of Homeland Security official on computer security and information security policy, and "war czar" to oversee the wars in Iraq and Afghanistan. More specifically, a czar refers to a sub-cabinet-level advisor within the executive branch of the U.S. government. One of the earliest known usages of the term was for Judge Kenesaw Mountain Landis, who was named Commissioner of Baseball, with broad powers to clean up the sport after it had been dirtied by the Black Sox scandal of 1919.

An emperor is a monarch, and usually the sovereign ruler of an empire or another type of imperial realm. Empress, the female equivalent, may indicate an emperor's wife, mother, or a woman who rules in her own right. Emperors are generally recognized to be of a higher honour and rank than kings. In Europe, the title of Emperor has been used since the Middle Ages, considered in those times equal or almost equal in dignity to that of Pope due to the latter's position as visible head of the Church and spiritual leader of the Catholic part of Western Europe. The Emperor of Japan is the only currently reigning monarch whose title is translated into English as Emperor.

Grand duke is a European hereditary title for either certain monarchs or members of certain monarchs' families.

Roman emperor ruler of the Roman Empire

The Roman emperor was the ruler of the Roman Empire during the imperial period. The emperors used a variety of different titles throughout history. Often when a given Roman is described as becoming "emperor" in English, it reflects his taking of the title Augustus or Caesar. Another title often used was imperator, originally a military honorific. Early Emperors also used the title princeps. Emperors frequently amassed republican titles, notably princeps senatus, consul and pontifex maximus.

Stefan Uroš V

Imperator rank in ancient Rome

The Latin word imperator derives from the stem of the verb imperare, meaning 'to order, to command'. It was originally employed as a title roughly equivalent to commander under the Roman Republic. Later it became a part of the titulature of the Roman Emperors as part of their cognomen. The English word emperor derives from imperator via Old French Empereür. The Roman emperors themselves generally based their authority on multiple titles and positions, rather than preferring any single title. Nevertheless, imperator was used relatively consistently as an element of a Roman ruler's title throughout the principate and the dominate. In Latin, the feminine form of Imperator is imperatrix.

In Latin sources the title is usually translated as comes or princeps, but the word was originally derived from the Proto-Germanic *kuningaz (king).

Despotate of Epirus former country

The Despotate of Epirus was one of the Greek successor states of the Byzantine Empire established in the aftermath of the Fourth Crusade in 1204 by a branch of the Angelos dynasty. It claimed to be the legitimate successor of the Byzantine Empire, along with the Empire of Nicaea and the Empire of Trebizond, its rulers briefly proclaiming themselves as Emperors in 1225/1227–1242. The term "Despotate of Epirus" is, like "Byzantine Empire" itself, a modern historiographic convention and not a name in use at the time.

The title grand prince or great prince ranked in honour below king and emperor and above a sovereign prince. It also ranked below an Archduke, although this is debatable.

This is a list including all rulers who had carried the title of emperor through history.

Byzantine Empire under the Macedonian dynasty

Autokrator Greek epithet for one exercising absolute power, unrestrained by superiors; applied to military commanders-in-chief and to Roman and Byzantine emperors as the translation of the Latin title imperator

Autokratōr is a Greek epithet applied to an individual who exercises absolute power, unrestrained by superiors. In a historical context, it has been applied to military commanders-in-chief, and to Roman and Byzantine emperors as the translation of the Latin title imperator. Its connection with Byzantine-style absolutism gave rise to the modern terms autocrat and autocracy. In modern Greek, it means "emperor", and the female form of the title is autokrateira.

Emperor of the Serbs

Between 1345 and 1371, the Serbian monarch was selftitled emperor (tsar), the full title being Emperor of the Serbs and Greeks and Bulgarians in Serbian and basileus and autokrator of Serbia and Romania ["the land of the Romans"] in Greek. This title was soon enlarged into "Emperor and Autocrat of the Serbs and Greeks, the Bulgarians and Albanians". The Serbian Empire was ruled by only two monarchs; Stefan Dušan and Stefan Uroš V. Two other claimants of the title ruled in Thessaly, Central Greece.

King class of male monarch

King, or king regnant is the title given to a male monarch in a variety of contexts. The female equivalent is queen regnant, while the title of queen on its own usually refers to the consort of a king.

"Kayser vnnd Herscher aller Rewssen und Groszfürste zu Wolodimer" in the German text of Maximilian's letter; "Imperator et Dominator universorum Rhutenorum et Magnus Princeps Valadomerorum" in the Latin copy. Vasily III responded by referring to Maximilian as "Maximiliano Dei gratia Electo Romanorum Caesare", i.e., "Roman Caesar". Maximilian's letter was of great importance to Ivan the Terrible and Peter the Great, when they wished to back up their titles of "tsar" and "emperor", respectively. Both monarchs demonstrated the letter to foreign ambassadors; Peter even referred to it when he proclaimed himself Emperor.
  14. This objection may be used against translating "Basileus" as "emperor", too. Based on these accounts, the Popes repeatedly suggested to confer on the Russian monarchs the title of rex ("king"), if they only ally themselves with Vatican. Such a proposal was made for the last time in 1550, i.e., three years after Ivan IV had crowned himself tsar. As early as 1489, Ivan III declined the papal offer, declaring that his regal authority does not require anyone's confirmation.

"Et ainsi retiennent le nom de Zar comme plus autentique, duquel nom il pleut iadis à Dieu d'honorer David, Salomon et autres regnans sur la maison de Iuda et Israel, disent-ils, et que ces mots Tsisar et Krol n'est que invention humaine, lequel nom quelqu'un s'est acquis par beaux faits d'armes".
