10 Things You Probably Didn’t Know About St. Patrick’s Day

Every year on March 17th, millions of people around the world celebrate St. Patrick’s Day with parades, music, Irish food, and enough green clothing to make a shamrock jealous. Even people who couldn’t locate Ireland on a map suddenly discover that their great-great-uncle once knew someone named O’Something.

But St. Patrick’s Day has a long and interesting history, and some of the facts behind the celebration may surprise you.

Here are ten things you may not know about St. Patrick’s Day—along with a few observations that might make you look at the holiday a little differently.

1. St. Patrick Wasn’t Actually Irish

One of the most famous symbols of Irish culture wasn’t born in Ireland at all.

St. Patrick was born in Britain sometime in the late 4th century. As a teenager he was kidnapped by Irish raiders and taken to Ireland as a slave. After several years he escaped, eventually returned as a missionary, and became one of Ireland’s most influential religious figures.

So technically, St. Patrick’s Day celebrates a British man who moved to Ireland and became famous there.

Which means the holiday may be the earliest recorded example of someone moving to a new country and becoming more patriotic than the locals.

2. The Original Color of St. Patrick’s Day Was Blue

Today, everything associated with the holiday is green—shirts, hats, rivers, and occasionally beverages of questionable origin.

But historically, the color associated with St. Patrick was actually blue, often called “St. Patrick’s Blue.”

Green became associated with the holiday later because of Ireland’s nickname, “The Emerald Isle,” and the use of shamrocks as a symbol of Irish identity.

Of course, if we still celebrated with blue beer instead of green beer, people might start asking more questions.

3. The First St. Patrick’s Day Parade Was Held in America

You might assume the first St. Patrick’s Day parade took place in Ireland.

Surprisingly, it didn’t.

The earliest recorded St. Patrick’s Day parade was held in St. Augustine, Florida, in 1601, organized by Irish settlers.

Which means America has been celebrating the holiday enthusiastically for more than 400 years—often with considerably more enthusiasm than Ireland itself.

4. Ireland Once Banned Alcohol on St. Patrick’s Day

Given the modern reputation of the holiday, this fact may come as a shock.

For many years in Ireland, St. Patrick’s Day was considered a religious holiday, and pubs were legally required to remain closed.

Yes, there was a time when St. Patrick’s Day involved church services rather than pub crawls.

History has a sense of humor.

5. Chicago Dyes Its River Green Every Year

One of the most famous St. Patrick’s Day traditions in the United States takes place in Chicago, where the Chicago River is dyed bright green each year.

The tradition began in 1962 when city officials used a dye originally intended to trace pollution leaks in the river.

Someone realized it looked festive, and the rest is history.

Fortunately, the modern dye used today is environmentally safe—though it still makes visitors wonder if the river is experiencing some kind of seasonal identity crisis.

6. There Are No Snakes in Ireland

Legend says St. Patrick drove the snakes out of Ireland.

In reality, Ireland never had snakes to begin with due to its climate and geographic isolation.

Which means the story is symbolic rather than literal.

Still, if someone ever claims to have seen a snake in Ireland on St. Patrick’s Day, it may be wise to ask how many green beverages they’ve had.

7. The Shamrock Was Used as a Teaching Tool

The shamrock became associated with St. Patrick because he supposedly used it to explain the concept of the Holy Trinity—three parts forming one whole.

Today, people wear shamrocks as a symbol of Irish pride.

It’s also a helpful reminder that sometimes the simplest illustrations can leave the strongest impression.

8. Corned Beef and Cabbage Isn’t Traditional Irish Food

In the United States, corned beef and cabbage is a classic St. Patrick’s Day meal.

However, the dish became popular among Irish immigrants in America, who substituted corned beef for the more traditional Irish bacon because it was more affordable and easier to find.

In Ireland, the traditional meal would more likely involve bacon and cabbage.

But let’s be honest—most people celebrating St. Patrick’s Day today are just happy if someone else does the cooking.

9. Over 13 Million Pints of Guinness Are Consumed on St. Patrick’s Day

Guinness estimates that more than 13 million pints of their famous stout are consumed worldwide on March 17th.

That’s a lot of stout.

It also explains why many people discover the next morning that they may have been slightly more enthusiastic about celebrating Irish culture than originally intended.

10. Everyone Becomes a Little Irish on St. Patrick’s Day

Perhaps the most charming tradition of the holiday is that everyone, regardless of heritage, feels welcome to celebrate.

On St. Patrick’s Day you’ll hear people proudly say things like:

“I’m Irish today!”

Even if their ancestry includes absolutely no connection to Ireland whatsoever.

But that’s part of the magic of the holiday. It’s a celebration of culture, community, and a little bit of fun.

And if you happen to see a leprechaun guarding a pot of gold at the end of a rainbow, please let me know.

I may have a few questions for him.
