Meaning and history
Kazimir is a Croatian, Slovene, and Russian form of Casimir, from the Polish name Kazimierz. It combines Slavic kaziti, “to destroy,” with mir, “peace” or “world,” giving the striking traditional sense “destroyer of peace.” Saint Casimir, a fifteenth-century Polish-Lithuanian prince and patron saint of Poland and Lithuania, gave the name religious importance. Notable bearers include Russian painter Kazimir Malevich, pioneer of Suprematism, and Croatian sculptor Kazimir Hraste.
In 2025, 29 babies were recorded with the name Kazimir, ranking #3,757 among boys.
