Saint Patrick, who lived during the fifth century, is the patron saint and national apostle of Ireland. Born in Roman Britain, he was kidnapped and brought to Ireland as a slave at the age of 16. He later escaped, but returned to Ireland and was credited with bringing Christianity to its people. In the centuries following Patrick’s death (believed to have been on March 17, 461), the mythology surrounding his life became ever more ingrained in the Irish culture: Perhaps the most well known legend is that he explained the Holy Trinity; the Father, Son and Holy Spirit using the three leaves of a native Irish clover, the shamrock.
n 1848, several New York Irish Aid societies decided to unite their parades to form one official New York City St. Patrick’s Day Parade. Today, that parade is the world ‘s oldest civilian parade and the largest in the United States, with over 150,000 participants. Each year, nearly 3 million people line the 1.5-mile parade route to watch the procession, which takes more than five hours. Boston, Chicago, Philadelphia and Savannah also celebrate the day with parades involving between 10,000 and 20,000 participants each.
