Casimir is an English, French and Latin form of the Polish name Kazimierz.
The name may mean "someone who destroys opponent's prestige/glory during battle", and is derived from the Slavic elements: kaziti "to destroy" and měr "prestige, fame". The latter element is also found in Vladimir, and is cognate to the Germanic and Celtic name element -mer or -mar (e.g. Dietmar) with similar meaning. It is often conflated with the word mir ("peace, world"), thus some sources translate the name as "the one who reveals or establishes 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.
