Casimiro Name Meaning, Origin & Popularity
/ka.si.ˈmi.ɾo/
Meaning of Casimiro: Casimiro is the Spanish, Portuguese, and Italian form of Casimir, itself derived from the Polish name Kazimierz. Kazimierz combines the Slavic roots kaz, meaning to command or destroy, and mir, meaning peace or world. The compound is conventionally rendered as proclaimer of peace, reflecting the dominant medieval Slavic interpretation.
The name gained wide recognition through Saint Casimir of Poland (1458-1484), the son of King Casimir IV Jagiellon. Saint Casimir became the patron of Poland and Lithuania, canonized in 1521 by Pope Adrian VI.
He was venerated for rejecting political ambition and his care for the poor. His feast day, March 4, is a national holiday in Lithuania today.
