Are you wearing any green today? Did you remember that today was St. Patrick’s Day? Just under 10% of the U.S. population claims at least some Irish ancestry, according to the most recent data from the American Community Survey. Less than one in 10 and yet, we’re about to see a whole lot of celebrating today. So how, exactly, did this become a thing?

Modern celebrations of the day, at least here in the States, are likely to be characterized by commercial lucky charms, a dyed green river and many, many glasses of green beer—all of which has very little to do with the historical figure of the saint.
 Of course, that’s par for the course with most of our holidays in America (Cinco de Mayo, anyone?)

St. Patrick had been Patron Saint of Ireland who had died around the fifth century. Since around the ninth or 10th century, people in Ireland have been observing the Roman Catholic feast day of St. Patrick on March 17. But the first St. Patrick's Day parade took place not in Ireland but in America. Records show that a parade was held on March 17, 1601 in a Spanish colony that’s now St. Augustine, Florida.

It wasn’t until the early 18th century that many of today’s traditions were kicked into high gear. Since the holiday falls during Lent, it provides Christians a day off from the prescriptions of abstinence leading up to Easter. And then around the 1720s, the church found it “got kind of out of control,” one historian tells TIME. But what about those lucky shamrocks? Modern legend has it that St. Patrick used the three-leafed plant to explain the Holy Trinity while preaching, but despite attempts to link the real-life figure to the practice, historians agree it’s just a fable.

The big parades and feasting on corned beef and cabbage? Those were American—not Irish—creations. And while North America is home to the largest productions, St. Patrick’s Day is celebrated around the world in locations far from Ireland, including Japan, Singapore and Russia. We may think of it as one big, boozy party but back in its homeland, St. Patrick’s Day has traditionally remained a spiritual and religious occasion. In fact, up until the 1970s, Irish laws mandated that pubs be closed on March 17th.

U.S. allies are resisting the Trump administration’s pressure to join an international coalition to reopen the critical Strait of Hormuz. The strait closure has become the main crisis in the war for the White House. As long as the Iranian blockade holds and Gulf oil remains trapped, the president can’t end the war and declare victory even if he wants to. Trump criticized allies who rebuffed his calls to help secure the Strait and postponed a planned summit with Chinese leader Xi Jinping, saying he wanted to be in the U.S. as the war continues.

And despite more than two weeks of relentless airstrikes, the Washington Post reports that U.S. intelligence assessments say that Iran’s regime likely will remain in place for now, weakened but more hard-line, with the powerful Islamic Revolutionary Guard Corps security forces exerting greater control. Western officials and analysts who study Iran said they see little near-term prospect of a “regime change” end to the 47-year-old Islamic republic or the rise of a more democratic government. The latter is a goal cited by Israeli Prime Minister Benjamin Netanyahu and sometimes by President Donald Trump, who has said he’ll know the war is over “when I feel it in my bones.”

American forces have struck more than 7,000 Iranian targets and damaged or destroyed more than 100 vessels since the war began, U.S. Central Command said. Saudi Arabia’s forces have intercepted nearly 100 drones in the last 24 hours and the United Arab Emirates reopened its airspace after a brief shutdown amid continuing Iranian attacks on infrastructure across the Gulf region. And still, oil prices continue to push higher.

It’s interesting, of course, but did we need to know? This announcement, that an extensive investigation by Reuters identified the legendary artist who goes by Banksy as Robin Gunningham—a man from Bristol who changed his name to David Jones and is linked to the influential company Pest Control, which authenticates his work. Apparently, it was a 26-year-old police report from New York, which helped confirm their suspicions.

Banksy’s iconic and provocative stencil paintings featuring social commentary have become some of the 21st century’s highest value artworks. Those who know his real identity, such as his former manager, Steve Lazarides, who subsequently fell out with the artist, have repeatedly preserved his anonymity. Reuters defended its investigation, saying that there was a public interest in understanding the identity and career of any public figure who influenced discourse.

Banksy’s lawyer, Mark Stephens, didn’t confirm the accuracy of the report. When Reuters reached out to him with questions, he said Banksy “does not accept that many of the details contained within your enquiry are correct.” He also said it’s important for Banksy to stay anonymous because he has “been subjected to fixated, threatening and extremist behavior” for his controversial work, which often reflects social justice efforts. And for many commenters, the bigger story is not whether Reuters may be right, but whether Banksy can ever really be “unmasked” in a way fans will accept. The artist’s anonymity has become central to the mythology around his work.
