St. Patrick is the patron saint of Ireland, but he was actually Scottish. He was captured by raiders as a teen and was taken to Ireland, where he was enslaved for many years. He converted to Christianity during this time and had prophetic dreams about leaving and ultimately saving Ireland. After he was ordained a bishop, he preached the Gospel and converted Irish pagans for 40 years. But he didn't actually drive away snakes from the country, as legend has it. That's because there were never any snakes in Ireland to begin with.
