This name derives from the Polish name “Kazimierz”, composed of two Slavic elements: “Kazać”, from the Proto-Slavic *kazati (казати) (to order, to tell someone to do something, proclaim, preaching) plus “*mir" (*mirъ) mir (мир)” (peace, calm, tranquility, universe, world), which in turn derives from the “the one who proclaims and preaches peace”. Some scholars translate this name as "the one who reveals or establishes peace". Other sources translate this name as "proclamation of peace". Several Polish kings have borne this name, including Casimir III the Great and Saint Casimir, a patron saint of Poland and Lithuania. The name was imported into Western Europe via Germany, where it was borne by some royalty. Feminine forms are: Casimira, Kazimiera, Kazimira and Kasimira.
