Historical Origins of St Patrick's Day

Saint Patrick was a Romano-British Christian missionary active in Ireland during the fifth century. According to tradition, he was captured as a youth and held in slavery in Ireland before returning home and later returning as a bishop to convert the Irish to Christianity.

By the seventeenth century, 17 March was observed as a religious feast in the Catholic Church in Ireland. Over time, especially with Irish diaspora communities in the United States and elsewhere, the day grew into a broader public celebration of Irish identity.
