Henry Symeonis: The Man Everyone Forgot (But Couldn't Forget!)

Once upon a time, in a place called Oxford, there was a rich man named Henry Symeonis. He lived a long, long time ago, way back in the year 1225! But Henry wasn't famous for building a giant castle or discovering a new planet. He's famous for something super weird: a grudge that lasted for over 550 years! That's longer than your great-great-great-great-great-grandparents have been alive!

At a famous school called the University of Oxford, students who graduated had to make a special promise. They had to swear they would NEVER make up with Henry Symeonis. It was like a rule that said, 'Don't be friends with Henry!' Even when people forgot who Henry was or why they were mad at him, they still had to make this promise. It was a very strange rule that lasted for ages!

After a while, the people at Oxford completely forgot why they were supposed to be mad at Henry Symeonis. They didn't even know who he was anymore! It was like forgetting your best friend's name. But the promise to stay mad at him stayed! This happened for so long that by the year 1600, nobody remembered Henry at all. It's like a secret that was lost and then found again!

For hundreds of years, Henry Symeonis was just a name on an old promise. Nobody knew his story! But then, in the year 1912, some clever people started digging through old books and papers. They found out who Henry was and why he was part of this super-long grudge. It's like finding a hidden treasure map that tells you a forgotten story!
