St. Casimir

Saint Casimir


Casimir was born in Krakow in the year of Our Lord 1458, the second son of King Casimir IV and Queen Elisabeth von Habsburg. He was tutored by Poland’s first historian, Fr. Johannes Longinus, and from an early age was a beacon of piety in the Polish court. Casimir’s deep devotion to the Blessed Mother is exemplified by the hymn Omni die dic Mariae, or “Daily, Daily Sing To Mary”, a copy of which was buried with him at his request. Though likely composed earlier, it is known to this day as the Hymn of St. Casimir. When the prince was fifteen, his father attempted to place him on the throne of Hungary, aided by discontented Hungarian nobles. Casimir assented, but reluctantly, and gladly turned back when it was learned that the Pope opposed the plan and the Hungarian claimant had amassed greater support. Prince Casimir lived out the rest of his life in fervent practice of the faith, maintaining perfect chastity and refusing marriage. He died of a lung affliction at the young age of twenty-three, and was soon hailed as a saint and a patron of Poland, Lithuania, and the youth.
