Czar vs. Tsar

Czar

Tsar (; Old Church Slavonic: ц︢рь [usually written thus with a title] or цар, цaрь), also spelled csar, or czar, 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.

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

First Bulgarian Empire, in 919-1018

Second Bulgarian Empire, in 1185–1396

Serbian Empire, in 1346–1371

Tsardom of Russia, in 1547–1721 (replaced in 1721 by imperator, but still remaining in use, also officially in relation to several regions until 1917)

Tsardom of Bulgaria, in 1908–1946The first ruler to adopt the title tsar was Simeon I of Bulgaria. Simeon II, the last Tsar of Bulgaria, is the last person to have borne the title Tsar.
