Casimir is Slavic in Origin.
Casimir is the Anglicized form of Polish Kazimierz, from Slavic elements kaz- and mir (“peace, world”). The first element is debated - linked either to kazać “to declare/command” or kazić “to corrupt” - so the traditional interpretation “proclaimer/keeper of peace” now prevails over the darker “destroyer of peace.” The name carries a stately, old‑world elegance while retaining an approachable rhythm in English.
It flourished in medieval and early modern Poland through rulers such as Casimir I the Restorer and Casimir III the Great, and gained pan‑European recognition via Saint Casimir, patron of Lithuania. The form spread into other languages: German Kasimir, French Casimir, Spanish and Italian Casimiro, Russian/Lithuanian Kazimir/Kazimieras, and Czech/Slovak Kazimír. English usage rose with Central European immigration and has enjoyed a quiet revival among vintage choices. Diminutives and nicknames include Kazik, Caz, Kaz, and Cass; feminine counterparts are Casimira and Kazimiera.
