Saint Patrick was born circa anno domini 387 and died 17 March 493. He was a Cymreig Celt from north Britain and was born in what is now southern Scotland. When Patrick was about 16, he was captured by Gaelic raiders and taken as a slave to Ireland. He lived for six years before escaping and returning to his family. After entering the Church he returned to Ireland as an ordained bishop and was a leading figure that brought Christianity to the north and west of the island. By the seventh century, he had come to be revered as the patron saint of Ireland. Irish folklore tells that one of his teaching methods included using the shamrock to explain the Christian doctrine of the Trinity to the Gaels. In Ulster he is still celebrated and remembered by Catholic, Presbyterian, and Anglican communities there. Veneration have been carried overseas to the vast Irish Diaspora.
