If you love bizarre historical facts that sound made up, you’re in the right place—these evidence-backed stories show how truth can outpace fiction and remind us the past was every bit as strange as the present.
7 Bizarre Historical Facts That Really Happened
1) The Dancing Plague of 1518
In Strasbourg, dozens began dancing in the streets and wouldn’t stop for days. Contemporary city records mention overworked bodies, rented musicians, and frantic council attempts to “cure” the outbreak by providing more music—an idea that likely made things worse. Explanations today range from mass psychogenic illness to ergot-contaminated rye. Whatever the cause, it reveals how communities interpreted crisis through the medical and religious beliefs of their time.
2) A Medieval Trial… for a Pig
In 1386 at Falaise, France, a pig was tried in a secular court after killing a child and was publicly executed. Surviving legal documents and accounts describe the full procedure—costs, witnesses, and even clothing for the condemned animal. Animal trials were rare but real, and they show how medieval justice tried to map human responsibility onto a world filled with hazards that modern people would treat as accidents.
3) The Cadaver Synod (897 CE)
Pope Formosus’s corpse was exhumed, dressed in papal robes, and placed on trial. A deacon answered for the dead pontiff while judges interrogated the body. After a posthumous conviction, his ordinations were annulled and his remains briefly discarded in the Tiber. The episode, documented in papal chronicles, reveals how vicious political rivalries spilled into ritual and law during a turbulent period in Rome.
4) The Great Molasses Flood of 1919
When a massive storage tank burst in Boston, a sticky wave up to 25 feet high ripped through streets at an estimated 35 mph, killing 21 and injuring scores more. Newspapers printed dramatic photos of toppled rail cars and ruined buildings. A landmark court decision later blamed poor construction and shoddy maintenance, and the case helped push forward engineering standards and building-safety reforms.
5) The Year Without a Summer (1816)
Mount Tambora’s colossal eruption launched sunlight-reflecting aerosols into the stratosphere. The following year saw failed harvests, food riots, and June snow in parts of North America and Europe. Stuck indoors by chill and gloom, a group at Lake Geneva held a ghost-story contest that nudged Mary Shelley toward Frankenstein. Climate can nudge culture in surprising ways.
6) Australia’s “Great Emu War” (1932)
To protect Western Australian wheat fields, officials brought soldiers with machine guns to cull fast-moving emus. The birds scattered, absorbed fire, and outpaced vehicles over rough terrain. The operation was quietly abandoned, leaving behind headlines and a lasting lesson: logistics, not firepower, often decides outcomes in the field.
7) Victorian Postmortem Portraits
Because early photography was expensive, some families took a first-and-only photo after a loved one died, posing them as if resting or alive. Albums and studio records confirm the practice. To modern eyes it can feel eerie; to grieving families it was a tender record in an age of high child mortality and scarce images.
How Historians Verify the Strange
When a story sounds unbelievable, researchers look for primary sources: city council minutes, parish books, court ledgers, shipping manifests, newspaper archives, and scientific reports. They compare independent accounts written by people with different motives, check dates against weather and astronomical records, and note how language changes across copies. The result is not just a fun anecdote but a window into law, faith, technology, and risk in earlier centuries.
Why These Tales Endure
- They flip expectations: Courts trying animals or syrup causing a deadly flood challenge our sense of “normal.”
- They’re well documented: Surviving paperwork and photos help separate legend from fact.
- They connect past to present: Public health, engineering, propaganda, and climate still shape our lives.
