The story of the Mary Celeste is really spooky. The Mary Celeste was a ship found adrift in the Atlantic Ocean in 1872. The ship was in good condition, but all of its crew had vanished without a trace. There were no signs of a struggle, the cargo was intact, and there was food and water still on board. It's a mystery that has never been fully solved. Some theories suggest mutiny, but there was no evidence of it. Others think that some supernatural force might have been involved, which makes it a very scary and unexplained event in history.
The tale of Genghis Khan's conquests can be considered scary in a way. Genghis Khan led the Mongol Empire to conquer vast territories. His armies were known for their brutality. They would often massacre entire cities. People lived in fear as his forces approached. For example, when his army reached the city of Nishapur, they killed almost every inhabitant, leaving the city in ruins. The scale of destruction and the fear that his name inspired across Asia and Europe make this a very dark and scary part of history.
