TsarTsar (zɑːr,_sɑːr or tsɑːr), also spelled czar, tzar, or csar, was a title used by Slavic monarchs. 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". It lends its name to a system of government, tsarist autocracy or tsarism.

Empire of TrebizondThe Empire of Trebizond (Αυτοκρατορία της Τραπεζούντας), or Trapezuntine Empire, was a monarchy and one of three successor rump states of the Byzantine Empire, along with the Despotate of the Morea and the Principality of Theodoro, that flourished during the 13th through to the 15th century, consisting of the far northeastern corner of Anatolia (the Pontus) and the southern Crimea. The empire was formed in 1204 with the help of the Georgian queen Tamar after the Georgian expedition in Chaldia and Paphlagonia, commanded by Alexios Komnenos a few weeks before the sack of Constantinople.
