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 (Father, Son and Holy Spirit) using the three leaves of a native Irish clover, the shamrock.
In modern-day Ireland, St. Patrick’s Day was traditionally a religious occasion. In fact, up until the 1970s, Irish laws mandated that pubs be closed on March 17.
Beginning in 1995, however, the Irish government began a national campaign to use interest in St. Patrick’s Day to drive tourism and showcase Ireland and Irish culture to the rest of the world.
Today, approximately 1 million people annually take part in Ireland ‘s St. Patrick’s Festival in Dublin, a multi-day celebration featuring parades, concerts, outdoor theater productions and fireworks shows.

It’s amusing how a religious holiday can be turned into green beer, frat boys, and numerous other annoyances.
