Every year on March 17th, people around the world don their best green outfits, raise a pint of Guinness, and celebrate Saint Patrick’s Day.But behind the parades, shamrocks, and rivers dyed green lies a fascinating history rooted in religion, culture, and plenty of Irish charm. Saint Patrick, the patron saint of Ireland, wasn’t actually Irish—he was born in Roman Britain around the late 4th century. Kidnapped by Irish raiders as a teenager, he was brought to Ireland as a slave. After escaping, he later returned as a missionary, spreading Christianity and, according to legend, using the three-leafed shamrock to explain the Holy Trinity. March 17th marks the date of his death, and over the centuries, it became a feast day honoring his work.
