On May eighteenth, nineteen twenty-seven, the deadliest school massacre in American history was carried out not with a gun, but with hundreds of pounds of dynamite. Last week we talked about history’s quiet birthdays and slow-burn revolutions—the moments that hum before they roar.
But May eighteenth is a day of roars. Some are the sounds of celebration, of empire, of mountains literally exploding. And some, like the bombs planted by a disgruntled school board member under a school in Bath, Michigan, are the sounds of a community, and a country, being torn apart.
It’s a day of shocking contrasts, a day that asks what we build, and what we choose to destroy. It’s a day that feels like a microcosm of history itself. And what a day it is. On this same date in nineteen eighty, the ground in Washington state didn't just shake—it dissolved.
A five-point-one magnitude earthquake triggered the catastrophic eruption of Mount St. Helens, a volcanic explosion so violent it sent ash eleven miles into the sky and completely remade the landscape for hundreds of square miles.
It was nature's raw, untamable power on full display. Then you have the manufactured power. On May eighteenth, nineteen seventy-four, India detonated its first nuclear device, codenamed "Smiling Buddha." With that single, secret test, India joined the world's most exclusive and terrifying club, forever changing the strategic map of Asia and announcing its own arrival as a global power, on its own terms.
The day is also about the power of the state over the individual. In nineteen seventeen, the U.S. Congress passed the Selective Service Act. In a moment, the nation went from a volunteer army to conscription, authorizing the government to draft millions of men to fight in World War One.
It was a decision that fundamentally reshaped the relationship between the American citizen and the state, and the echoes of that debate—about duty, liberty, and sacrifice—are still with us. But it’s not all explosions and legislation.
May eighteenth has its quiet revolutions, too. In eighteen fifty-two, Massachusetts passed the first law in the nation mandating school attendance for all children. Think about that. The idea that education wasn't a privilege for the wealthy, but a fundamental right and a public necessity… that was born right here.
Just seventeen years later, in eighteen sixty-nine, Robert Tanner Freeman walked across a stage at Harvard and became the first African American to graduate from a dental school in the United States. A single diploma that represented a crack in a wall that had seemed impenetrable.
And of course, it's a birthday. It's the birthday of the king of country, George Strait, born in nineteen fifty-two. And the birthday of the great filmmaker Frank Capra, born in eighteen ninety-seven, a man who built his career telling stories about the power of the common person to stand up to corrupt systems.
It's even the day, in nineteen fifty-three, that the incredible Jacqueline Cochran became the first woman to break the sound barrier, her plane roaring past Mach one. But I want to go back. Back past the twentieth century, past the nineteenth.
I want to put two emperors side-by-side, both of whom made a world-defining choice on May eighteenth, separated by nearly fifteen hundred years. On May eighteenth, eighteen-oh-four, in the soaring grandeur of Notre-Dame Cathedral in Paris, Napoleon Bonaparte is about to become Emperor of the French.
The French Revolution had promised liberty, equality, and fraternity, but it descended into terror and chaos. Into that power vacuum stepped this short, unbelievably ambitious Corsican general. And he won. He won on the battlefield, he won in the political arena, and now, he was ready for his coronation.
But this was not going to be just any coronation. The Pope, Pius the Seventh, was there, as tradition demanded. But as the moment arrived to place the crown on Napoleon’s head… Napoleon took it. He took the crown from the Pope’s hands, turned his back on the altar, and crowned himself.
The sheer, unmitigated audacity! Then he crowned his wife, Josephine. The message was not subtle. It was a thunderclap. My power does not come from God. It does not come from the Church. It does not come from ancient tradition. It comes from me.
From my will, my ambition, my victories. It was the ultimate act of self-creation. And it set Europe on a course for more than a decade of war, conquest, and bloodshed, all while spreading the ideals of the revolution—and the Napoleonic Code—across the continent.
It was the birth of a modern kind of power, rooted in personal charisma and military might. Now. Let's rewind. All the way back. One thousand, four hundred and seventy-two years earlier. The year is three thirty-two CE. The emperor is Constantine the Great.
He has consolidated the Roman Empire under his rule, he has legalized Christianity, and he has just founded a new capital city in the east, a "New Rome" that will bear his name: Constantinople. Building a city is one thing. Building a vibrant, stable, world-leading metropolis is another.
You need people. Lots of them. And you need them to feel secure. You need them to feel that the state… that the Emperor… is on their side. So what does Constantine do on May eighteenth, three hundred and thirty-two? He doesn't stage a lavish ceremony.
He doesn't declare a new war. He institutes a policy of free daily bread for the citizens of his new capital. Let that sink in. This isn't just a handout. This is statecraft of the highest order. This is a social contract written in flour and water.
It’s an early form of a social safety net, a public welfare program designed to ensure stability, prevent riots, and bind the people of the city to their ruler not just through fear or spectacle, but through a tangible, daily benefit.
It’s a promise. The promise that in this city, under this emperor, you will not starve. It was a policy that would last, in some form, for centuries. So here we have it. Two emperors. Two May eighteenths. Two acts that define an empire.
Napoleon, at the dawn of the modern age, seizes a crown in an act of supreme ego, declaring his power is his own. His legacy is one of brilliant, bloody, transformative conquest. Constantine, in the twilight of the ancient world, gives away bread, an act of supreme pragmatism, declaring his power serves the stability of his people.
His legacy is a city that would be the heart of an empire for another thousand years. One man’s power is a performance, for himself. The other's is a tool, for his society. One is about personal glory. The other is about public good.
Both are forms of leadership. Both are empire-building. But they are building two profoundly different kinds of worlds. And the fact that both of these defining acts happened on the same calendar day… it’s a beautiful, jarring reminder that at every turn, history presents us with a choice.
So what does this one day, this May eighteenth, tell us? It tells us that history is not one thing. It is creation and it is destruction, sometimes in the same moment. It’s the day a mountain explodes and the day a man graduates against all odds.
It’s the day a nation decides it can draft its sons for war, and another state decides it must educate its children for peace. It’s the day a man plants bombs in a school and the day an emperor gives his people bread. May eighteenth isn't just a date.
It’s a collection of blueprints. A blueprint for empire. A blueprint for social welfare. A blueprint for terror, and a blueprint for resilience. Looking back at this one day, this one chaotic, brilliant, tragic cross-section of human history, the question it leaves us with isn't about the past.
It's about which of those blueprints we are still using today.
