What Does the Name Kasimir Mean?
Kasimir is the German form of the Slavic name Polish Kazimierz, recorded in Latin as Casimirus. It is a two-part compound name. The second part is mir, "peace" (from Proto-Slavic mirъ, which could also carry the senses "world" or "community"). The first part is disputed. One explanation connects it with Old Polish kazać, "to preach, to proclaim, to command," which gives a literal sense of "proclaimer of peace" or "commander of peace." Another connects it with kazić, "to destroy, to ruin, to spoil," which would give "destroyer of peace." Which of the two lies behind the name has not been settled, and the customary English gloss "peacemaker" reflects the first, more favorable reading rather than a proven fact.
Kasimir Name History & Origins
The name is attested in Poland by the 11th century. Kazimierz I, called the Restorer (born 1016), son of Mieszko II Lambert, was duke of Poland, and the name continued in the Piast dynasty: Kazimierz II the Just ruled in the late 12th century. It was later borne by Kazimierz III the Great (1310 - 1370) and by Kazimierz IV Jagiellon (1427 - 1492), king of Poland and grand duke of Lithuania. The Kraków district of Kazimierz, laid out in the 14th century, is named for a king of that name.
Latin documents wrote the name Casimirus, and from that Latin form come the English Casimir and the German Kasimir. Kasimir became the usual spelling and pronunciation in German-speaking Central Europe, while the Czech and Slovak form is Kazimír, the Hungarian Kázmér, and the Lithuanian Kazimieras.
Saint Casimir (Polish Kazimierz, 1458 - 1484), a son of King Casimir IV, was canonized in 1521 and is a patron saint of Poland and Lithuania. Devotion to him gave the name a lasting religious association in both countries. In the 20th century the form Kazimir was borne by the painter Kazimir Malevich (born Kazimierz Malewicz), who was of Polish descent.
