The History of St. Patrick's Day
Saint Patrick was a 5th-century Christian missionary credited with bringing Christianity to Ireland. He was actually born in Britain around 387 AD, kidnapped by Irish raiders at age 16, and held as a slave in Ireland for six years before escaping. He later returned voluntarily as a missionary bishop. The Roman Catholic Church established March 17 as his feast day in the 9th or 10th century. The first official St. Patrick's Day parade did not take place in Ireland — it was held in St. Augustine, Florida in 1601 by Spanish colonists. The first New York City parade — now the largest in the world — was held in 1762 by Irish soldiers serving in the British Army. Ireland did not start its own parades until 1903; until 1970, Irish law actually closed pubs on St. Patrick's Day.
St. Patrick's Day Traditions
St. Patrick's Day customs blend genuine Irish heritage with American invention. Wearing green is universal — the color is associated with Ireland (the "Emerald Isle") and the shamrock. Parades fill major cities; the New York City parade marches up Fifth Avenue and draws 2 million spectators. In Chicago, the Chicago River is dyed bright green every St. Patrick's Day morning — a tradition started in 1962. Many cities host pub crawls and outdoor parties. Traditional Irish foods (corned beef and cabbage, Irish soda bread, shepherd's pie) are served, along with green beer, Guinness stout, and Irish whiskey. The shamrock — a three-leaf clover — is the symbol of the day, said to have been used by St. Patrick to explain the Holy Trinity.
