Saint Patrick was a Christian missionary and bishop in Ireland. He is the primary patron saint of Ireland, also known as one of the Apostles of Ireland. He is also venerated in the Anglican Communion, the Old Catholic Church and in the Eastern Orthodox Church as equal-to-the-apostles and Enlightener of Ireland.
The dates of Patrick's life cannot be fixed with certainty, but there is broad agreement that he was active as a missionary in Ireland during the second half of the 5th century. Early medieval tradition credits him with being the first bishop of Armagh and Primate of Ireland, and they regard him as the founder of Christianity in Ireland, converting a society practising a form of Celtic polytheism. He has been generally so regarded ever since, despite evidence of some earlier Christian presence in Ireland.
According to the Confessio of Patrick, when he was about 16, he was captured by Irish pirates from his home in Britain and taken as a slave to Ireland, looking after animals; he lived there for six years before escaping and returning to his family. After becoming a cleric, he returned to northern and western Ireland. In later life, he served as a bishop, but little is known about the places where he worked. By the seventh century, he had already come to be revered as the patron saint of Ireland.
