More than 100 St. Patrick's Day parades are held across the United States; New York City and Boston are home to the largest celebrations. Since around the ninth or 10th century, people in Ireland have been observing the Roman Catholic feast day of St. Patrick on March 17. Interestingly, however, the first parade held to honor St. Patrickâs Day took place not in Ireland but in the United States. On March 17, 1762, Irish soldiers serving in the English military marched through New York City.
