Tsarina

Tsarina (or tsaritsa; Cyrillic: царица) is the title of a female autocratic ruler (monarch) of Bulgaria, Serbia, and Russia, or the title of a tsar's wife. The English spelling is derived from the German czarin or zarin, in the same way as the French tsarine / czarine, and the Spanish and Italian czarina / zarina. A tsar's daughter is a tsarevna.
