St. Patrick was born in Britain in the 4th century and was kidnapped to Ireland as a teenager where he was enslaved for six years before escaping. After becoming a priest, he returned to Ireland as a missionary to teach Christianity to the pagans and died on March 17th. Now celebrated worldwide on March 17th, St. Patrick's Day began as a celebration in Boston in 1737 and later had a parade in Dublin in 1931, with people wearing green and having traditional Irish meals to honor the patron saint of Ireland.
