St. Patrick’s Day is celebrated annually on March 17, the anniversary of his death in the fifth century. The Irish have observed this day as a religious holiday for over 1,000 years. On St. Patrick’s Day, which falls during the Christian season of Lent, Irish families would traditionally attend church in the morning and celebrate in the afternoon. Lenten prohibitions against the consumption of meat were waived and people would dance, drink and feast–on the traditional meal of Irish bacon and cabbage.
Saint Patrick, who lived during the fifth century, is the patron saint of Ireland and its national apostle. 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 of St. Patrick is that he explained the Holy Trinity (Father, Son and Holy Spirit) using the three leaves of a native Irish clover, the shamrock.
Since around the ninth or 10th century, people in Ireland have been observing the Roman Catholic feast day of St. Patrick on March 17. The first St. Patrick’s Day parade took place not in Ireland but in America.

The parade, and a St. Patrick’s Day celebration a year earlier were organized by the Spanish Colony's Irish vicar Ricardo Artur.
More than a century later, homesick Irish soldiers serving in the English military marched in New York City on March 17, 1772 to honor the Irish patron saint. Enthusiasm for the St. Patrick's Day parades in New York City, Boston and other early American cities only grew from there.
Over the next 35 years, Irish patriotism among American immigrants flourished, prompting the rise of so-called “Irish Aid” societies like the Friendly Sons of Saint Patrick and the Hibernian Society. Each group would hold annual parades featuring bagpipes (which actually first became popular in the Scottish and British armies) and drums. Continue reading from History Channel
