The origins of St. Patrick’s Day 

March 17th marks the feast day of St. Patrick, the patron saint of Ireland, who is credited with bringing Christianity to the Emerald Isle in the 5th century. Born in Roman Britain in the late 4th century, he was abducted at the age of 16 and brought to Ireland as a slave. After escaping, he returned around 432 CE with the mission of converting the Irish to Christianity. By the time of his death on March 17, 461, he had founded monasteries, churches, and schools and numerous legends emerged about him.

Myths and traditions

As with much of Ireland’s history, St. Patrick’s Day is rich with myths and traditions that only add to the day’s appeal.  On March 17th it is customary to wear shamrocks, which can be found growing wild throughout Ireland. According to legend, St. Patrick used the three-leafed shamrock to explain the Holy Trinity to the Irish people, symbolizing the Father, the Son, and the Holy Spirit. He said the three leaves stand for the three beings of God, and the stem shows how they are united into one. The tradition of wearing Shamrock on Saint Patrick’s Day can be traced back to the early 1700’s.

One legend that is heavily debated is that of the snakes. Legend has it that he banished all snakes from Ireland, symbolizing the defeat of paganism in his mission to spread Christianity. However, this tale is likely more myth than reality, as scientists argue that post-glacial Ireland never actually had snakes. Rather, the story embodies his victory over the serpent-like forces of evil and ignorance, reflecting the larger conflict between paganism and Christianity in Ireland during his era.

 

Going green

According to folklore, wearing green renders you invisible to leprechauns —mischievous fairy creatures known for pinching anyone they can see. This lighthearted belief inspires people to wear green, whether it’s through simple accessories or elaborate costumes.

In reality, green’s significance as an Irish color is known to have political origins that trace back to the Great Irish Rebellion of 1641. During this uprising, Catholic local leaders opposed the English crown and adopted a green flag featuring a harp as their emblem. Green made a reappearance during the Irish Rebellion of 1798. Before these rebellions, blue was the color traditionally associated with Ireland.

Why St Patrick’s Day became a global celebration

St. Patrick’s Day evolved into a global celebration through a combination of Irish immigration, cultural pride, and the diaspora’s efforts to maintain connections to their heritage. It began to transform in the 18th century, particularly in the United States.

As millions of Irish immigrants made their home in America, they sought to assert their identity in this new land, giving rise to the first parades in cities such as New York and Boston. These festivities highlighted Irish culture, nurturing community spirit and pride in the face of discrimination. Over time, the festivities evolved into more secular and fun occasions, celebrating Irish ancestry through music, dance and parties.

St. Patrick’s Day around the world

Today, St. Patrick’s Day is marked globally, transcending cultural boundaries and celebrated by millions regardless of their ancestry. In fact, it can be hard to avoid!

Major US cities like New York, Boston and Chicago host some of the largest and most famous parades, drawing thousands of spectators. The Chicago River is famously dyed green to kick off the city’s festivities, in Sydney Australia the Opera House is lit up green and in Rio de Janiero Brazil, the 98-foot-tall Christ the Redeemer statue is lit green atop Sugarloaf Mountain. Buenos Aires, Pisa, Tokyo and Kuala Lumpur all light their iconic buildings.

Some of the more bizarre celebrations around the world include partaking in a vegetable food fight, featuring the ingredients of an Irish stew, at the huge New Orleans’ St Patrick’s day parade, and in New London, Wisconsin, leprechauns change all the signs in the city to “New Dublin” for the day.

Given that St. Patrick was a significant figure in Christianity, many still observe his feast day as a religious occasion. Attending mass and reflecting on the saint’s contributions to the spread of the Christian faith in Ireland remains important for many believers.
