You probably think of May Day in one of two ways. Maybe you picture kids in flower crowns dancing around a wooden pole with ribbons. Or, maybe you see grainy footage of tanks rolling through Red Square or massive worker protests in downtown Chicago. It’s weird. How did a day about spring flowers become the global epicenter of labor strikes and political upheaval? Honestly, the history of May Day is a messy, beautiful, and sometimes violent collision of ancient pagan rituals and gritty industrial revolution politics. It isn't just one holiday. It’s two different worlds fighting for the same calendar square.
Early humans were obsessed with the seasons. Obviously. When the sun finally started sticking around after a brutal winter, people threw a party. This is the "Beltane" side of the story. In Gaelic traditions, May 1 marked the halfway point between the spring equinox and the summer solstice. They lit massive bonfires. They drove cattle between the flames to "purify" them. It was about fertility—not just for people, but for the soil and the livestock.
Then the Romans showed up with Floralia. This was a festival for Flora, the goddess of flowers. It was basically a week of theatrical performances, bright clothing, and throwing beans and lentils at people for good luck. You can see where the May Pole comes from here. It’s a literal phallic symbol. It’s about the earth waking up and getting reproductive. For centuries, this was just how Europe spent the first of May. It was a day for "bringing in the May," where villagers would go into the woods at night and return with hawthorn blossoms.
The Haymarket Affair and the Radical History of May Day
Everything changed in the late 19th century. If you lived in 1880s America, work was hell. We’re talking 10 to 16-hour days in dangerous factories. No weekends. No safety nets. Children losing fingers in looms. By 1884, the Federation of Organized Trades and Labor Unions (which later became the AFL) decided they’d had enough. They passed a resolution stating that "eight hours shall constitute a legal day's labor from and after May 1, 1886."
They gave the bosses two years to comply. They didn't.

When May 1, 1886, rolled around, more than 300,000 workers across the U.S. walked off the job. Chicago was the heart of it. It was a massive general strike. For a few days, it was peaceful. Then, on May 3, police fired into a crowd at the McCormick Reaper Works, killing several people. This sparked a protest meeting the next day at Haymarket Square.
It was raining. The crowd was actually thinning out when the police moved in to disperse the meeting. Suddenly, someone—to this day, nobody knows who—threw a dynamite bomb into the police ranks. The explosion killed officer Mathias J. Degan and eventually seven others. The police opened fire.
The aftermath was a total witch hunt. Eight anarchists were arrested and tried, despite there being zero evidence linking them to the bomb. Four were hanged. One committed suicide in his cell. This event didn't just fade away; it became a global symbol of the struggle for workers' rights. In 1889, a group of socialist and labor parties in Paris (the Second International) officially declared May 1 as International Workers' Day to commemorate the "Haymarket Martyrs."
Why the U.S. Doesn't Celebrate on May 1
Wait. If the history of May Day as a labor holiday started in Chicago, why do Americans celebrate Labor Day in September?
It was a deliberate move to kill the radical vibes.
President Grover Cleveland was terrified that a May 1 holiday would become a yearly rally for socialism and anarchy. It was too "red." So, in 1894, he signed legislation making the first Monday in September the official Labor Day. He chose a date that was already being used by the Knights of Labor, which felt more "American" and less "revolutionary." Later, during the Cold War, the U.S. took it a step further. In 1958, President Eisenhower declared May 1 "Loyalty Day" to counter the massive May Day parades happening in the Soviet Union.
It’s a bit ironic. The rest of the world celebrates a holiday born in America, while Americans celebrate a substitute holiday designed to make them forget the original one.
The Rebirth of the Maypole
While the labor movement was getting tear-gassed, the old-school pagan May Day was having a bit of a mid-life crisis. In the Victorian era, people got nostalgic. They started reviving "Old English" traditions. This is where the modern, sanitized version of the Maypole comes from.
It wasn't always just for kids. In the 1600s, the Puritans absolutely hated May Day. Oliver Cromwell basically banned Maypoles, calling them "heathenish vanities." He thought the whole thing was an excuse for lewd behavior in the woods. He wasn't entirely wrong, but the ban didn't last. When the monarchy was restored, the Maypoles came back, bigger than ever. In London, a massive 134-foot Maypole was erected in the Strand.
Today, you see this split personality everywhere. In Oxford, England, thousands of people gather at 6:00 AM to hear the Magdalen College Choir sing from the top of a tower. Then they all go to the pubs. Meanwhile, in Berlin or Paris, May 1 is still a day for massive street protests, often ending in clashes with police.

Modern May Day: Climate and Immigration
The history of May Day isn't stuck in the 1800s. It keeps evolving. In the 21st century, it has become a massive day for immigrant rights, especially in the United States.
Remember the "Day Without an Immigrant" in 2006? Millions of people marched to protest harsh immigration laws. They chose May 1 specifically to reclaim the radical labor roots of the day. They connected the struggle of the 1886 factory worker to the struggle of the modern undocumented farmworker or delivery driver.
It’s also becoming a day for climate activism. The logic is simple: you can’t have labor rights on a dead planet.
Understanding the Nuance
You'll hear people say May Day is "Communist." That's a huge oversimplification. While the Soviet Union certainly co-opted the day for military displays, the origins are much broader. It’s about the "Three Eights": eight hours for work, eight hours for rest, eight hours for what we will.
It’s also not just a "European" thing. In many parts of the world, May 1 is a public holiday where families just go to the park. It’s a day of rest. It’s one of the few global holidays that isn't tied to a specific religion, which gives it a unique, secular power.
If you look at the research by historians like Eric Hobsbawm, you see that May Day was the first "international" holiday created from the bottom up. It wasn't handed down by a king or a pope. It was demanded by people who were tired of being treated like machines.
Actionable Ways to Observe May Day Today
Knowing the history of May Day is great, but the day is meant to be lived. Whether you lean toward the floral side or the labor side, here is how you can actually participate in the tradition without it feeling like a history lecture.
- Support Local Labor: May 1 is a great time to tip your service workers extra or look into local union efforts. If there's a strike happening in your area, stop by with some coffee or water. It’s a direct nod to the Haymarket legacy.
- Plant Something: Lean into the Beltane roots. If you have a garden, May 1 is the traditional time to get your summer crops in the ground. If you live in an apartment, get a new houseplant. It's about acknowledging the change in season.
- Leave a "May Basket": This is a dying tradition that deserves a comeback. People used to leave small baskets of flowers or treats on neighbors' doorknobs, ring the bell, and run away. It’s a simple, low-stakes way to build community.
- Check Your Work-Life Balance: The core of the 1886 movement was about time. Use May 1 as a hard reset. Turn off your Slack notifications. Don't check your email. Reclaim your "eight hours for what we will."
- Educate on the Haymarket Eight: Most people have no idea that the "weekend" and the "8-hour day" were paid for in blood. Take ten minutes to read the final speeches of August Spies or Albert Parsons. It’s heavy stuff, but it puts your 9-to-5 into perspective.
The first of May is a weird hybrid. It’s a day of tension. It’s the tension between the beauty of nature and the harshness of industry. It’s the tension between resting and fighting. But maybe that’s exactly why it has survived for thousands of years. We need the flowers, but we also need the rights to be able to enjoy them.
