Who doesn't like a good mystery? And if the mystery isn’t a work of fiction but the result of a true story, even better! The great unsolved enigmas of history are absolutely fascinating. Some have been solved over time, but there are still many old secrets for which neither scientists nor historians have found an explanation—yet. Time-travel with us as we uncover 10 of the biggest historical mysteries that will probably never be cracked!

Bermeja Island is mentioned in navigation texts written by European travelers and appears in cartography from the 16th to 19th centuries. Old maps place it off the north coast of the Yucatán Peninsula; however, multiple searches over the years have yielded no concrete evidence of its existence.

So, what happened to Isla Bermeja? Was it a cartographic error? Did it sink due to a tidal wave? Because of its geopolitical significance, some have even suggested that it was blown up by the CIA! A 2009 study by the Autonomous University of Mexico concluded that Isla Bermeja does not exist today, nor were any traces found at its supposed coordinates. Yet, it will forever remain a mystery that will surely keep many entertained.

In 1977, Ohio State University’s Big Ear radio telescope, used in the search for extraterrestrial intelligence, detected a signal now known as the Wow! signal. While reviewing the data, astronomer Jerry R. Ehman noticed a sequence represented as "6EQUJ5." Baffled by the anomaly, he circled it and wrote "Wow!" in the margins.

The signal lasted 72 seconds and, unfortunately, has never been repeated. To this day, no one can fully explain the phenomenon, although some suggest it may have come from a man-made source. Still, the Wow! signal remains one of the strongest candidates for potential extraterrestrial contact ever detected.

How is it possible for an entire village to vanish without a trace? Believe it or not, this is said to have happened nearly a century ago. According to lore, a small Inuit village in Canada was well known among fur trappers who visited regularly to trade. But in 1930, something very strange supposedly occurred.

A hunter named Joe Labelle claimed he visited the village one day and couldn’t find a single person. Reports said there were guns and food left behind, and even claims that the graves in the cemetery were empty. A thorough investigation, however, found no conclusive evidence of what happened to the villagers. Some witnesses from nearby towns even reported seeing a huge green light. Theories ranged from mass migration to extraterrestrial abductions. The Royal Canadian Mounted Police has since dismissed the case as an urban legend. Some still believe the story to be true.

We know thousands of shipwreck stories, but this one is quite unique. The MV Joyita, designed to be nearly unsinkable, was found adrift in the South Pacific, practically unharmed, but the crew had disappeared completely.

In October 1955, the American merchant vessel left the port of Apia in Samoa with 16 crew members and 9 passengers bound for the Tokelau Islands. After days without news, a rescue mission was launched. Five weeks later, the Joyita was spotted more than 600 miles west of its intended route. The vessel was partially submerged, and there was no sign of the passengers or crew. Four tons of cargo and all three life rafts were missing. They were never seen again.

Do you know where one of the best-preserved mummies was found? Hint: not in Egypt. Xin Zhui, the Marquise of Dai during the Western Han Dynasty in China, was discovered in her tomb at Mawangdui 2,000 years after her death, along with hundreds of valuable documents and artifacts.

What makes this mummy so extraordinary is how well-preserved her body is. Her organs and veins remain intact, and she still has hair and even eyelashes. Scientists analyzed the fluid present in the coffin and discovered it was acidic and contained salt and magnesium. They believe this mysterious liquid may have been responsible for preserving Xin Zhui so well. What they don’t know is whether it was intentionally poured into the coffin or came from the body itself.

The United States has its fair share of presidents who died while in office, but none of our 45 presidents have ever disappeared without a trace. Did you know that this actually happened in The Land Down Under?

Harold Edward Holt was the Prime Minister of Australia from 1966 until his presumed death in 1967. He loved the ocean and spearfishing. During a weekend trip with friends, Holt visited the remote Cheviot Beach to take a swim. Rough sea conditions that day caused him to be swept away by the waves, and he never reappeared. Despite an intensive search, his body was never found, which has given rise to numerous conspiracy theories. Ironically, Australians built the Harold Holt Memorial Swimming Centre in Melbourne in his honor.

Many famous criminals have managed to remain unidentified for decades, but the D.B. Cooper case is something else entirely. In 1971, Cooper boarded a flight from Portland to Seattle. Shortly after takeoff, he showed a flight attendant a device he claimed was a bomb and demanded four parachutes and $200,000 in cash.

The crew landed to meet Cooper’s demands in exchange for the passengers and then took off again. As the plane flew over southwestern Washington, Cooper jumped into the cold, rainy night carrying his haul. His whereabouts and true identity were never discovered, although it is likely he didn’t survive the jump. In 1980, some of the ransom money was found near the Columbia River. Although the FBI officially closed the case in 2016, amateur sleuths continue to try to crack it.

Can you imagine an epidemic where the main symptom is uncontrollable dancing? Sounds like science fiction, doesn’t it? Yet this really happened during the Middle Ages. In 1518, a dancing plague struck Strasbourg, Alsace, in what is now France. This strange condition affected up to 400 people, making them dance frantically for weeks. It is said that some even died of heart attacks, exhaustion, or strokes.

Doctors and authorities tried all kinds of measures to stop the spread. They even banned music for a while! To this day, scientists are not certain what caused this bizarre condition: it may have been food poisoning from toxins in the ergot fungus, or perhaps a case of stress-induced mass hysteria.

The Voynich manuscript is a codex written roughly 500 years ago in an unknown language and writing system by an anonymous author. Known as Voynichese, the manuscript was named after Wilfrid Voynich, a Polish bibliophile and antiquarian who purchased it in 1912.

Radiocarbon testing has shown that it dates to the early 15th century. Many cryptographers and codebreakers have attempted to decipher its roughly 240 pages without success. The manuscript contains diagrams and illustrations of unknown plants and astrological symbols. Some believe it may be a made-up language, a secret code, a work of fiction, or even a hoax. If you think you can solve this mystery, the Voynich manuscript is available for viewing at Yale University’s Beinecke Rare Book and Manuscript Library.

Similar to the Voynich manuscript, the Phaistos Disc is a fired clay disc believed to have been created during the Bronze Age. It was discovered by an Italian archaeologist in the basement of a palace in Crete, Greece, in 1908.

What makes this disc fascinating is that it contains a mysterious message. Stamped into the clay is a set of signs, forming a text that many scientists have tried to decipher—without success. It is considered an early attempt at printing, a technological innovation that would not become widespread for several centuries. While enthusiasts still hope the enigma can be solved, this is unlikely unless other documents are discovered to provide context.

Wacky history

Cods and pigs: 10 strangest "wars" that actually happened

Not all conflicts are fought for power or territory—some "wars" erupted over pies, buckets, and even unsuspecting animals. Human history, it seems, can be incredibly unpredictable. From bizarre misunderstandings to centuries-long stalemates over trivial disputes, here are 10 of the strangest "wars" ever fought.

In 1838, French pastry chef Remontel demanded compensation after his shop in Mexico was looted by soldiers. France sent warships to collect, escalating into an all-out war.

When Mexico refused to pay, France blockaded Veracruz and bombarded the city. The war only ended when Britain mediated, leading to Mexico paying 600,000 pesos to avoid further conflict.

A land dispute over a strip of land called the Toledo Strip caused Ohio and Michigan to nearly go to war in the 1830s. The states armed militias but only exchanged minor skirmishes.

The conflict only ended when the federal government intervened, awarding Ohio the disputed land and giving Michigan the Upper Peninsula as compensation.

In 1925, a Greek soldier chased his stray dog across the Bulgarian border and was shot, sparking hostilities. In response, Greece invaded, capturing several villages before the League of Nations intervened.

Greece was ordered to withdraw and pay reparations to Bulgaria. Despite its absurd start, the conflict helped prove the effectiveness of international diplomacy in averting larger wars.

A 20th-century conflict, the Cod Wars were disputes between Iceland and the UK over fishing rights in the North Atlantic. Iceland extended its fishing boundaries several times, angering British trawlers.

Despite no deaths, the confrontations involved ramming ships and cutting nets. Iceland eventually prevailed, asserting control over its waters and reshaping international fishing agreements.

In 1932, Australia deployed soldiers to manage an emu overpopulation wreaking havoc on crops. Using machine guns, they expected an easy victory but were surprisingly outwitted by the agile birds, accomplishing nothing.

The campaign failed spectacularly, and emus remains a humorous symbol of nature’s resistance to human efforts, even to its military might! The government later turned to fencing to manage the problem without making fools of themselves.

In 1325, rival Italian city-states Bologna and Modena clashed when Modenese soldiers stole a bucket from Bologna's city well. A large battle ensued, resulting in well over 2,000 deaths.

Eventually, Modena triumphed, and the bucket is still displayed as a trophy in the city. While the origins of the conflict might seem bizarre, it highlights the intense (and sometimes absurd) rivalries between independent cities in medieval Italy.

In 1859, on the still undefined U.S.-Canada border, a stray pig innocently crossed the border to eat vegetables from a neighboring farm, prompting an angry farmer to shoot it. This led to a feud with his neighbor that escalated into a military standoff between American and British forces, which lasted months.

The "war" only ended when the border issue was peacefully resolved through international arbitration. Fortunately, there were no casualties, except for the poor pig.

This conflict between the Netherlands and the Isles of Scilly began during the English Civil War. According to local historians, the small archipelago declared war on the Netherlands but never bothered to sign a peace treaty afterward.

Despite no fighting, it technically lasted over 300 years due to the forgotten declaration of war. In 1986, a peace treaty was finally signed, bringing an end to one of history’s most prolonged and bloodless "wars."

Since the 1970s, Denmark and Canada have engaged in a playful "war" over Hans Island, with each side leaving flags and bottles of whisky or schnapps during their visits.

The dispute was finally resolved in 2022, with the island being split between the two nations. This resolution also resulted in Canada and Denmark sharing a land border, meaning neither country borders just one other—the United States in the case of Canada, and Germany in the case of Denmark.

In 1784, the Holy Roman Empire and the Dutch Republic clashed over trade rights, with the Dutch winning the conflict by firing only one shot. The only casualty? A kettle of soup.

Apparently, when the bullet ricocheted off the metal container, the captain became so nervous that he immediately surrendered. While this incident wasn’t the last conflict between the two states, it remains a humorous example of history’s quirks.
