Tradition holds that Saint Patrick, the patron saint of Ireland, died on March 17, around the year 461, at Downpatrick. A Romano-British missionary who had once been carried to Ireland as a captive, he returned as a bishop and is credited with spreading Christianity across the island.

Much of his story is woven from legend — the shamrock used to explain the Trinity, the banishing of snakes — and scholars debate the year of his death, with some preferring a date closer to 493. The exact details are unrecoverable, but the March 17 commemoration has held firm for centuries.

The feast was fixed on the Church calendar in the early 1600s, largely through the Irish Franciscan scholar Luke Wadding.

What began as a solemn religious feast has since grown into a global celebration of Irish identity, marked with parades and a great deal of green far beyond Ireland’s shores.
