Tsar
Slavic imperial title derived from Latin caesar, used in Bulgaria, Serbia, Russia.
Tsar is a Slavic title derived from the Latin word caesar, intended to mean 'emperor' in the European medieval sense—a ruler with the same rank as a Roman emperor, holding it by the approval of another emperor or a supreme ecclesiastical official. It was usually considered by Western Europeans to be equivalent to 'king'. The title and its variants were official 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).

Lore & Background
The title tsar entered Slavic languages through the Gothic term kaisar and was used as an equivalent of the Greek basileus, which referred to Byzantine emperors and biblical kings. The first monarch to adopt the title was Simeon I of Bulgaria, following a makeshift imperial coronation by the Patriarch of Constantinople in 913. After warfare, the Byzantine government recognized his imperial title in 924 and again in 927. In Serbia, the title was used officially by two monarchs: Stefan Dušan, crowned emperor in 1346, and his son Stefan Uroš V. In Russia, the first ruler formally crowned as tsar of all Russia was Ivan IV in 1547, though earlier grand princes used the title in foreign relations.
Reader's Guide
The title tsar carried significant political and religious weight, serving as a claim to imperial status equal to that of Byzantine or Holy Roman emperors. In Bulgaria and Serbia, its adoption was a direct challenge to Byzantine authority, while in Russia it evolved into a central symbol of autocratic rule, especially after the fall of Constantinople. Over time, its meaning shifted: in Bulgaria after 1908 it was not generally perceived as equivalent to 'emperor', and in Russia by the 18th century it was increasingly viewed as inferior to 'emperor' or as highlighting the oriental side of the rank. The title persisted in the full imperial style of Russian rulers until the monarchy's abolition, and the last living person to have held it is Simeon II of Bulgaria.
