Why do we celebrate “St. Patrick’s Day” in America?
For Catholics, St. Patrick is the patron saint of Ireland. Born in Roman Britain in the late 4th century (when England was under occupation by the Roman Empire), he was kidnapped at the age of 16 and taken to Ireland as a slave. He escaped but returned in roughly 432 CE to convert the Irish to Christianity. Notably, aside from founding monasteries, churches, and schools, there were also myths and legends surrounding his legacy — e.g. that he drove the snakes out of Ireland and that he used the shamrock leaf to explain the Holy Trinity to proselytes — such that Ireland came to celebrate the day of his death (March 17, 461 CE) with religious services and a national feast.
