Casimir II of Poland/Talk

so who is this? Casimir II or Casimir III? Any time kings have multiple numbers (James the Sixth the First springs to mind) those numbers should be explained immediately! AND this is linked off the Rulers of Poland entry as Casimir III!!!!! --MichaelTinkler

He's refered in Polish almost only as 'Casmir the Great', without any numbers. --Taw
