Bonus Episode — Why We Celebrate St. Patrick’s Day


A Curious by Design Subscriber Special


Green shirts.

Green rivers.

Green beer.


Every March 17th, the world turns green—but most of what we associate with St. Patrick’s Day didn’t actually begin in Ireland.


In this subscriber special of Curious by Design, we explore how a quiet religious feast day honoring a 5th-century missionary transformed into one of the most recognizable cultural celebrations in the world.


The story begins with Saint Patrick, a kidnapped teenager from Roman Britain who was enslaved in Ireland before eventually returning as a Christian missionary. After his death around the year 461, March 17th became a modest religious observance in Ireland—more about church services and family meals than parades or parties.


The modern celebration took shape somewhere else entirely.


Irish immigrants in 18th- and 19th-century America used St. Patrick’s Day parades as public expressions of identity and pride during a time of intense discrimination. Over time, symbols evolved: the shamrock, the color green tied to Irish nationalism, and eventually traditions like green beer and massive parades.


This episode traces how religion, immigration, politics, and tourism layered together over centuries to create the holiday we recognize today—one that eventually became so popular abroad that Ireland itself re-imported the celebration in the 1990s.


St. Patrick’s Day didn’t just appear fully formed.


It evolved—

through migration, culture, and reinvention.


And once you see the layers behind it, March 17th starts to look a little different.


That’s Curious by Design.
