History’s Greatest Unanswered Questions

Unsolved World History is an independent history blog by Kylie Lang about the mysteries the past left behind: lost civilizations, vanished people, strange objects and events nobody has ever fully explained.

It digs into the strange, the unexplained, and the stories that never got a proper ending. From cities swallowed by the jungle to ships that sailed off the map, every piece lays out the evidence, the theories, and the clues that still don’t add up. Whether you’re here for a good old-fashioned mystery, a forgotten figure, or a fresh take on something you thought you knew, this is the place for history’s loose ends.

ABOUT THE AUTHOR

Kylie Lang

HISTORY WRITER AND FOUNDER OF TALES OF THE MIDDLE AGES

History's unanswered questions have always pulled me in. Give me a sealed tomb, a message nobody can read, or a ship that sailed off the map, and I'm hooked.

I'm a British writer who has lived in rural France since 2016, surrounded by castles, churches, and ruins that are older than most countries. Every one of them has a story that someone forgot to finish. In 2024, I founded Tales of the Middle Ages, where I write about the real people, battles, and scandals of medieval Europe. Unsolved World History is where I chase the stories that still don't have an ending.

Here, you'll find lost cities, vanished explorers, codes that have beaten the cleverest minds for centuries, and objects that simply shouldn't exist. I go back to what the records and the archaeology actually say, lay out every theory worth your time, and tell you which one I'm inclined to believe. Some of them are wonderfully bonkers. Trust me.

If you've ever lain awake wondering what really happened to the Roanoke colonists, or who carved the first stone circles, pull up a chair. You're in good company.
