Longest War In The History

My grandfather used to tell me about a fight he had with his neighbor over a fence that was two inches out of place. They didn’t speak for seventeen years. Seventeen years. And all because of a misaligned wooden plank. I always laughed, thinking that was the definition of stubborn, petty humanity—until I learned about the real longest war in history.

The War That Didn’t Bother to Fight

Turns out, grandpa was an amateur. The Three Hundred and Thirty-Five Years’ War between the Netherlands and the Isles of Scilly (a tiny archipelago off England) lasted from 1651 to 1986. That’s over three centuries. You’re probably thinking: Wait, what did they even fight over?

Believe it or not, it started by accident during the English Civil War. The Dutch, allied with the Parliamentarians, demanded reparations from the Royalist-held Scilly Isles. When the Royalists refused, the Dutch declared war. Then the Royalists surrendered a few months later. But here’s the kicker—nobody remembered to sign a peace treaty.

For 335 years, the Netherlands and Scilly were technically at war. No battles. No casualties. Just an awkward, bureaucratic zombie war that sat in a dusty file cabinet. I love that. Can you imagine getting a tax bill with a footnote that says, “Oh, and you’re still at war with a bunch of islands”?

The Runner-Up: The Arauco War (But That’s Boringly Real)

If you want a war where people actually died—constantly—look at the Arauco War between the Spanish Empire and the Mapuche people in Chile. It started in 1536. It lasted over 300 years. The Spanish tried to conquer them; the Mapuche said, “Nah, we’re good.” By the time it fizzled out in the 19th century, Chile was an independent country, and the Mapuche were still fighting for their land. Spoiler alert: they lost most of it.

But that one’s grim. Let’s stick with the funny, bureaucratic version of the longest war, okay?

The Peace Treaty That Finally Arrived

In 1986, a historian named Roy Duncan noticed the Scilly–Netherlands war was still technically active. He contacted the Dutch ambassador. A peace treaty was signed on April 17, 1986, with no hard feelings and a lot of embarrassed laughter. The Dutch ambassador joked, “It must be a comfort to the Scillonians to know we could have attacked at any moment.” Talk about holding a grudge for the ages.

The war officially ended, but the islanders celebrated with free beer and a ceremony. I mean, can you blame them? They’d been under threat of a Dutch naval invasion for three and a half centuries—but only on paper.

What This Says About Us

We humans have a talent for absurdity. We’ll declare war over a trade dispute, then forget about it while our grandkids are playing video games. The longest war in history wasn’t a clash of empires; it was a cosmic oversight. A printer jam in the peace process. It’s a reminder that most conflicts—personal or global—are often about neglect more than malice.

Think about your own grudges. That argument you had with a friend three years ago? That’s your own personal Scilly War. You didn’t mean to keep it alive; you just never bothered to bury it. And guess what? You can end it with a simple phone call—or a peace treaty signed over coffee.

The Ironic Twist

Here’s the truly wild part: during that 335-year “war,” the Netherlands and Scilly never once fired a shot at each other. But people died in real wars that only lasted a few weeks. The lesson? Prolonged conflict is usually a sign of inertia, not strength. We keep fights alive because it’s easier than admitting we forgot to apologize.

So next time you’re a month into a silent treatment with someone, remember the Scilly Islands. They waited 335 years to shake hands. Don’t be like them. (Unless you’re waiting for free beer—then maybe it’s worth it.)

Take it from my grandpa: he built a new fence after seventeen years, and they ended up being friends again. It wasn’t war; it was just two stubborn people who forgot to say, “This is stupid.” The longest war in history teaches us that most battles are only as real as the paper they’re written on—or the silence we let fester. So go make peace. Your neighbors are probably nice. And if they aren’t? Well, at least don’t wait until 1986.
