'''Tsar''' ({{IPAc-en|z|ɑːr|,_|(|t|)|s|ɑːr}}; also spelled '''''czar''''', '''''tzar''''', or '''''csar'''''; {{langx|bg|цар|tsar}}; {{langx|ru|царь|tsar'}}; {{lang-sr-Cyrl-Latn|цар|car}}) is a Slavic title derived from the Latin word ''caesar'',<ref name="Vodoff"/> 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—but was usually considered by Western Europeans to be equivalent to "king".<ref>{{Cite book|last=Margeret|first=J.|url=https://books.google.com/books?id=atYFs7aWsLkC&pg=PA111|title=The Russian Empire and Grand Duchy of Muscovy|publisher=University of Pittsburgh|year=1983|isbn=9780822977018|pages=111|quote=The Slavonic Bible did equate the terms "tsar" and "king"...

Tsar and its variants were the official titles in the First Bulgarian Empire (681–1018), Second Bulgarian Empire (1185–1396), the Kingdom of Bulgaria (1908–1946), the Serbian Empire (1346–1371), and the Tsardom of Russia (1547–1721). The first monarch to adopt the title of tsar was Simeon I of Bulgaria.<ref>"Simeon I." Encyclopædia Britannica. 2009.

==Etymology== The title ''tsar'' is derived from the Latin title ''caesar'', used for the Roman emperors.<ref name=eponym>{{cite web|url=http://www.etymonline.com/index.php?term=tsar|title=Online Etymology Dictionary|work=etymonline.com}}</ref><ref name="Vodoff">{{cite book |last1=Vodoff |first1=Vladimir |editor-last1=Vauchez |editor-first1=Andre |title=Encyclopedia of the Middle Ages |volume=2 |date=2000a |publisher=Fitzroy Dearborn Publishers |isbn=978-1-57958-282-1 |url=https://www.oxfordreference.com/display/10.1093/acref/9780197599020.001.0001/acref-9780197599020-e-9130|chapter=Tsar |page=1469 |language=en}}</ref> It entered the Slavic languages through the Gothic term ''kaisar'' and was used as an equivalent of the Greek term ''basileus'', which referred to Byzantine emperors and the kings of the Bible.<ref name="Vodoff"/> The Greek equivalent of the Latin word ''imperator'' was the title ''autokrator''.

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''.<ref>Срђан Пириватрић. ''Самуилова држава''. Београд, 1997.</ref>

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 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.<ref>''Innocentii pp. III epistolae ad Bulgariae historiam spectantes''. Recensuit et explicavit Iv. Dujcev. Sofia, 1942.</ref>

After Bulgaria's liberation from the Ottomans in 1878, its new monarchs were at first ''autonomous prince'' (knyaz). 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<ref>Найден Геров. 1895–1904. Речник на блъгарский язик. (the entry on цар in Naiden Gerov's ''Dictionary of the Bulgarian Language'')</ref> (although Paisius' ''Slavonic-Bulgarian History'' (1760–1762) had still distinguished between the two concepts).

==Serbia== {{Further|Emperor of the Serbs|List of Serbian monarchs}} [[File:Serbian Emperor Stefan Dušan, cropped.jpg|right|thumb|Tsar Dušan of Serbia]]

The title of ''tsar'' (Serbian ''car'') was used officially by two monarchs, the previous monarchical 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.<ref>{{Citation |chapter=Empire (c.1170–1459) |date=2023 |title=A Concise History of Serbia |pages=83–139 |editor-last=Djokić |editor-first=Dejan |url=https://www.cambridge.org/core/books/concise-history-of-serbia/empire-c11701459/D8DD1C6481FED34AFB34350304B2AE7A |access-date=2025-12-29 |series=Cambridge Concise Histories |place=Cambridge |publisher=Cambridge University Press |isbn=978-1-107-02838-8}}</ref>

The title ''tsar'' was used once by church officials of Kievan Rus' in the naming of Yaroslav the Wise, the grand prince of Kiev ({{reign | 1019 | 1054}}).

The title ''tsar'' remained in common usage, and also officially as part of various titles signifying rule over various states absorbed by the Russian monarchy (such as the former Tatar khanates and the Georgian Orthodox kingdom). In the 18th century, ''tsar'' was increasingly viewed as inferior to "emperor" or as highlighting the oriental side of the rank.<ref>Boris Uspensky.

Among the indigenous peoples of Siberia and the Muslims of the Volga region, Central Asia and the Caucasus, the autocracy of the Russian Empire often became identified with the image of the "White Tsar" ({{langx |ru| Белый царь}}).<ref> {{cite book |last1 = Hofmeister |first1 = Ulrich |editor-last1 = Banerjee |editor-first1 = Milinda |editor-last2 = Backerra |editor-first2 = Charlotte |editor-last3 = Sarti |editor-first3 = Cathleen |date = 2017 |chapter = From the ''White Tsar'' to the ''Russian Tsar''.

==Metaphorical uses== {{See also|Czar (political term)}}

Like many lofty titles, such as mogul, tsar or czar has been used in English as a metaphor for positions of high authority 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.<ref name="EtymonlineCzar">{{Cite web |title=Czar (etymology and metaphorical usage) |url=https://www.etymonline.com/word/czar |access-date=21 August 2025 |publisher=Online Etymology Dictionary}}</ref>

In the United States and in the United Kingdom, the title "czar" is a colloquial 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 in the US government typically refers to a sub-cabinet-level advisor within the executive branch. 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 sullied by the Black Sox scandal of 1919.<ref>{{cite news|title=Close, But No Big Czar |author=James K.
