St. Patrick's Day is best known for parades, beer, and turning rivers green, but the holiday has a long history that's more somber than its current incarnation.

Saint Patrick St. Patrick was born around 387 C.E. in Scotland, and turned to God once he was kidnapped by slave traders and brought to Ireland to be a shepherd.

"The love of God and his fear grew in me more and more, as did the faith, and my soul was rosed, so that, in a single day, I have said as many as a hundred prayers and in the night, nearly the same," he wrote, according to Catholic Online. "I prayed in the woods and on the mountain, even before dawn. I felt no hurt from the snow or ice or rain."

He joined the priesthood after his escape at the age of twenty, and eventually became a bishop. Patrick was tasked with the mission of bringing Christianity to Ireland, where he was enormously successful in converting much of the mainly Druid and pagan population.

History St. Patrick's Day originated as a Roman Catholic holiday recognizing St. Patrick, and was brought to America by Irish immigrants as a way of affirming their identity. It's since been adopted by Americans of all backgrounds.

NEW YORK CITY

<em>Photo Credit: Stuart Monk / Shutterstock</em>    New York hosts the country’s and the world’s largest <a href="http://www.nycstpatricksparade.org/home.html" target="_hplink">St. Patrick’s Day celebration</a>, with more than two million people gathering for the city’s grand parade on March 17. The march up Fifth Avenue starts at 11 am on 44th Street and lasts about six hours, ending at 79th, with a stop at the St. Patrick’s Cathedral along the way. There are no floats or cars allowed in the parade, which features bands, bagpipes, and dancers, and typically between 150,000 to 250,000 participants. The tradition itself dates back to 1762, making the NYC St. Patrick’s Day Parade older than the U.S. itself.

DUBLIN

<em>Photo Credit: Aitormmfoto / Shutterstock</em>    Of course, Dublin hosts one of the biggest St. Patrick’s Day celebrations, with a four-day festival filled with boat races, the Irish Beer & Whiskey Festival, music and street performances, and a spectacular parade. This year the festival runs from March 14 through March 17. The parade, which takes place on St. Patrick’s Day, attracts about half a million spectators to watch the procession from Parnell Square to St. Patrick’s Cathedral.

CHICAGO

<em>Photo Credit: Thomas Barrat / Shutterstock</em>    The city of Chicago truly commits to <a href="http://www.chicagostpatsparade.com/parade-and-river-dyeing.html" target="_hplink">St. Patrick’s Day </a>by dyeing the Chicago River green every season. The tradition dates back to 1961, when the chairman of the annual parade saw green dye in the river (which at the time was used to identify a sewage problem) and got the idea to use it for the upcoming holiday. On the Saturday before St. Patrick’s Day, this year falling on March 14, more than 400,000 people gather along the Chicago River to watch 45 pounds of environmentally-safe vegetable dye turn the murky river a bright shade of green. After the morning's dyeing ceremony, even more spectators gather for the city’s parade at noon. The parade lasts about three hours, with dancers and bands making their way up Columbus Drive through Grant Park.
