20 Mysterious Events Historians Still Can’t Explain

One of the most popular mysterious events ever recorded was the two missing sons of England’s King Edward IV. Edward V and his brother Richard were last seen alive in 1483 inside the Tower of London. Suspicions of their disappearance were directed towards their uncle, Richard III, based on a dispute over the throne. At the same time, though, there are also speculations that one or both of them escaped the Tower and lived under assumed names, away from the throne.

If you think you can dance all night long, well, these people beg to differ. In a weird turn of events, an estimated 50 to 400 people from the city of Strasbourg began dancing uncontrollably and weren’t able to stop at all. This phenomenon went on for days until many dancers collapsed from extreme exhaustion; later popular accounts claimed dozens died, though contemporary 1518 records do not confirm any fatalities. And this outbreak, dubbed the dancing mania, still occurred on different occasions between the 14th and 17th centuries. For the love of dancing? Mass psychogenic illness? Nothing is confirmed even now!

After making sure over 100 English colonists were able to settle on Roanoke Island off the coast of North Carolina in 1587, John White sailed home to gather supplies. But imagine his surprise when he sailed back three years later to find a deserted island with only one word carved on a post as a clue. “Croatoan” is what it says. White’s hunch is that they must have moved to nearby Croatoan Island, but due to several weather disturbances, he never had a chance to check it.

The American vessel Mary Celeste was found seaworthy but disheveled, with water in its hold and rigging in disarray, sailing through the Atlantic in December 1872. So, what seems to be the problem? No one was aboard; it was a complete ghost ship. Its passengers and the captain’s family were missing, along with a single lifeboat. The strangest part was that despite all this, the ship’s log looked completely normal, showing no sign of trouble before it was found abandoned. Several theories were proposed, but nobody could pinpoint exactly how the passengers vanished in the middle of the sea.

Not one but three lighthouse keepers on the remote Flannan Isles in Scotland vanished from their stations in December 1900. The scene was left in disarray, with two of the three keepers’ oilskins missing, and records show that they had worked up until December 15. Officials closed the case, attributing it to a storm accident, but their disappearance still remains a mystery.

The infamous killer known as Jack the Ripper murdered and mutilated the bodies of at least five women in London in 1888 and was never identified or caught. He was famous for his record of being able to dodge the police, and up until now, he has plagued everyone with the thought of whether they must have just passed by him randomly on the streets. He was active in London, England, but I’m still spooked by the possibility of meeting him even though I’m basically 7,000 miles away, by the way.

The Siberian Forest saw millions of trees flattened for miles as a massive explosion tore through it on the morning of June 30, 1908. It was recorded as the largest impact event in history. However, it left quite a mystery since there was no crater of a size consistent with an explosion that massive. The only viable explanation experts can offer is that an asteroid might have exploded above the surface, but it’s still only a mere speculation.

Having enough hours of sleep is good, but being asleep for years and unable to move may not be the best thing to desire, but that is what happened to a number of people who got the sleeping sickness or encephalitis lethargica. Between roughly 1915 and 1930, over a million people were struck with this disease, and about half a million died. Up until today, there has been no viable explanation, but only theories about a virus or immune response that messes with the brain.

Edmund Hillary and Tenzing Norgay are recognized as the first people to reach the summit of Mount Everest in 1953. But there’s a mystery that still fascinates climbers today because in 1924, George Mallory and Sandy Irvine vanished high on the mountain. No other evidence was found that they had reached the summit before dying, though Mallory’s body was found in 1999, and part of Irvine’s remains turned up in 2024. The camera they likely had with them, which may hold the answer, is still missing.

The Peking Man fossils were once considered one of archaeology’s greatest discoveries. It was found near Beijing in the 1920s; this discovery offered a rare glimpse into our early human ancestors. But when World War II reached China, the fossils were packed up and sent away to the U.S. for protection. Unfortunately, they never made it to their destination, and no one has seen them since.

The disappearance of the Sodder children remains one of America’s most enduring mysteries. After a fire destroyed the family’s West Virginia home on Christmas Eve in 1945, five children out of ten were never accounted for. Searchers never found anything that could lead to where the children had gone. With no physical evidence, suspicions grew around the circumstances surrounding the fire, and later reports of possible sightings led the family to believe the children may have been kidnapped instead.

The Amber Room looks exactly how it sounds: an architectural masterpiece made almost entirely of amber and earned the nickname “the Eighth Wonder of the World.” Built in the early 1700s, the room was looted from Russia by Nazi Germany during World War II, and it was displayed in Germany for a time. But as the war was coming to a close, the room also vanished with no real lead as to what had happened to it.

In 1959, nine experienced hikers camped in Russia’s Ural Mountains and cut their way out of their tents in the middle of the night. They ran into sub-zero temperatures without bringing most of their gear and were found frozen to death. While hypothermia claimed most of their lives, a few had unexplained injuries that sparked countless theories.

Even if you were not alive yet at the time, you may still be familiar with then-President John F. Kennedy’s assassination. The case still came as a shock to everyone as the events unfolded messily, even after the shooting in Dallas. The suspect, Lee Harvey Oswald, was arrested, but before he could appear in court, nightclub owner Jack Ruby shot him during a live television broadcast. The Warren Commission officially concluded that Oswald acted alone, and Ruby was convicted of killing him, yet decades later, the case continues to raise questions that may never be fully answered.

Much like the Jack the Ripper case, the Zodiac Killer’s identity was never discovered. Active in California during the late 1960s, the killer claimed responsibility for several murders and challenged police with a series of coded letters sent to newspaper outlets. Some of those messages have been solved over the years, but others remain a mystery. Still, no leading clues about their identity have ever been discovered.

Being hijacked on a plane is one of my biggest nightmares. Unfortunately, this happened in November 1971 when a man who called himself Dan Cooper hijacked a flight headed for Seattle from Portland and claimed to have a bomb on him. He collected a ransom worth $200,000 and escaped by parachuting from the plane after releasing the passengers. Investigators searched for him but found nothing but a small portion of the ransom money in a river.

Jimmy Hoffa was known as the powerful and mob-connected leader of the Teamsters union when he suddenly disappeared on July 30, 1975. He was last seen in Oakland County, Michigan, and then seemed to vanish without a trace. Although he was declared legally dead years later, no one has ever found his body or determined who was responsible for his disappearance. Investigators have searched everywhere from Detroit to a New Jersey landfill, but every search has led to nothing.

Aliens might be real after all (I’m kind of hoping they are)! For just over a minute in the late 1970s, the Big Ear radio telescope at Ohio State University detected a signal that immediately caught the attention of many. It was so unusual that it earned the name “Wow! signal.” Scientists regarded this as an intriguing, unexplained signal rather than proof of extraterrestrial life, and spent years listening and hoping to hear it again, but it never happened the second time.

One routine flight became one of aviation’s greatest mysteries, enough to have TV shows get inspired by it. Malaysia Airlines Flight 370 left for Beijing with 239 people on board before disappearing less than an hour later. The aircraft changed course after its transponder stopped transmitting and was later tracked only through satellite signals. Although search teams spent years looking across the Indian Ocean, they recovered very little evidence to explain what happened.

I know the song Havana by Camila Cabello and witnessed how it took the world by storm in 2017, but the Havana Syndrome here actually came a year before the song, so it’s safe to say it’s a different one. The first instances came from Havana (yes, the actual place), where American diplomats described hearing a strange sound before developing symptoms such as dizziness and nausea. Then it happened again later in China. Experts still have no explanation for what caused the illnesses. I believe they just needed to hear the song by Camila, though, and dance it all out. Kidding!
