10 More Historical Myths That Needs Debunking

History is full of details that feel true because they are neat, dramatic, and easy to picture: Cavemen communicate in a series of shrugs and grunts. Medieval people cowering at the edge of a flat Earth. George Washington never telling a fib. Einstein failing math in school.

These portrayals are immediately taken at face value. The problem is that the most memorable version is often the least accurate one.

Here we debunk 10 historical myths—some of them so often repeated, we naturally believe they're true. We discuss what likely happened instead.

1. Cave people were stupid.

Prehistoric humans, including those living in the Paleolithic era, had brains the same size and cognitive capacity as modern humans. Now that fact alone does not mean that ancient humans were as smart as modern humans. But they had more than enough brain capacity to invent clever tools and jewelry.

Here's what "cavemen" created: sophisticated tools and weapons made of stone and bone, artwork showing symbolic thought (e.g., cave paintings preserved at Lascaux and Chauvet in France, Spain, Indonesia, and many countries around the world), jewelry, complex social structures, trade networks, and burial practices. The grunting, dim-witted caveman image is a cultural stereotype, not a scientific fact.

2. The Romans invented gladiator games.

Most historians believe gladiatorial combat originated with the Etruscans or Samnites (pre-Roman Italic peoples), possibly as a funerary ritual. Among historians, the exact origin is still contested.

The Romans adopted, expanded, and popularized the combat practice into the large-scale, state-sponsored public spectacle we associate with the Colosseum (~80 CE). They knew it was "good business" to appease the populace with grand entertainment via the gladiator games. But they didn't invent the game concept from scratch.

3. Marie Antoinette said, “Let them eat cake.”

This line is often used as proof that Marie Antoinette was heartless, lacking awareness, or both. The story goes when told the poor had no bread to eat, the queen replied, “Let them eat cake.” The phrase in French, "qu'ils mangent de la brioche" (roughly translated, "let them eat brioche"), was a rhetorical trope used in French writing to demonstrate the cluelessness of aristocrats towards the suffering of the poor—not a real quotation from any specific royal.

So, there is no solid evidence that Antoinette said the line. The quote was likely attached to her, probably during and after the French Revolution, because it matched what her enemies wanted people to believe. Antoinette was the target of fierce public hatred and propaganda before her husband King Louis XVI was executed in January 1793. She was executed in October 1793.

A similar phrase appears, before Marie Antoinette became queen, in Jean-Jacques Rousseau's Confessions, written around 1765-1767. Rousseau credits the line to "a great princess," not identifying who it was. When he wrote his autobiography, Marie Antoinette was still a child in Austria. She arrived in France in 1770, becoming queen in 1774.

4. People during the Middle Ages drank mostly Beer and wine.

A popular claim says medieval people drank beer or wine all day because water was too unsafe. It sounds plausible, especially in towns with poor sanitation. Alas, that claim is false.

People of this era did drink plenty of ale, beer, wine, and cider, often at lower strength than many modern versions—especially amongst the nobles and clerics living in monasteries. Alcoholic drinks provided calories, flavor, and safety benefits. People did not know at the time how pathogens work in causing diseases and that the processes of brewing and fermentation kill off harmful germs.

Yet people also drank water. The truth depended on the region, class, season, and local conditions. Poor peasants couldn't afford extravagant amounts of beer or wine, unless they knew how to make it themselves. Wells, springs, rivers, and collected rainwater were common drinking sources for the poorer populations. Medical and household texts from the period mention water in ordinary ways—not to avoid it. So people drank plenty of water or extended their alcoholic drinks by diluting with water.

5. All people living in the middle ages believed the earth was flat.

The “flat medieval Earth” myth is one of the most frequent errors modern people repeat about the past. Many educated people in medieval Europe knew the Earth was spherical. Ancient Greek thinkers had argued for a round Earth—that knowledge did not simply vanish during medieval times.

Medieval scholars discussed the Earth’s shape, astronomy, and geography in ways that assumed it was globular. Theologians, academics, and sailors did not all share the same level of knowledge. But the idea that most everyone living during this era believed ships would fall off the edge of the world is false.

6. Columbus proved the Earth was round

Closely related to the flat Earth myth is the claim that Christopher Columbus sailed west to prove the planet was round. He did not. Educated Europeans already knew the Earth was round.

The real debate involved the size of the Earth and the width of the Atlantic Ocean. Columbus underestimated how far west Asia was from Europe. His voyage succeeded, from his point of view, because the Americas lay in the way, not because he had correctly solved the math.

This matters because the myth gives Columbus credit for proving something that was not seriously in dispute among educated navigators. It also hides the more significant consequences of his voyages, including colonization, violence, forced labor, and the reshaping of the Atlantic world.

7. George Washington admitted to cutting a cherry tree because he never told a lie.

After given a hatchet as a gift, young George hacked off his father's precious English cherry tree because he wanted to use the tool. When asked by his father who cut off the tree, George admitted to the deed, although he was scared, saying, "I cannot tell a lie. I cut the tree." His father was so moved by his son's honesty, he relented from punishing George.

This legend was first written in a biography of the first U.S. president, The Life of Washington, by Mason Locke Weems (1806, 5th edition), seven years after Washington had died. Weems was known to embellish, exaggerate, and even, invent stories to illustrate concepts and character traits in his writing. The author claimed to have heard the cherry tree tale from a family friend of the Washingtons. But the story has not ever been verified and is mostly considered a fabrication of Weems' imagination.

8. Einstein failed math as a child.

This assertion is totally false. Albert Einstein showed strong mathematical ability early in life. He taught himself advanced topics as a teenager, having mastered calculus by age 15. He had no failures in school mathematics—and was quite brilliant at math and physics.

The myth may have grown from confusion over grading systems, or from the implication that Einstein did not always thrive in rigid school settings.

9. Germans invented the first working blimp.

The first powered, steerable airship is credited to Henri Giffard, a Frenchman, in 1852. Giffard made a steam-powered dirigible—a cigar-shaped hydrogen balloon with a steam engine—closer to the blimp design we have today. He flew his airship 17 miles (27 km) from Paris to Trappes.

Ferdinand von Zeppelin, a German, received more accolades for his rigid airship in 1900, which became the dominant design, the Zeppelin. But he wasn't first in creating a working blimp. The German claim is a common misconception.

10. Americans invented the first personal computers.

American computer models, the Hewlett-Packard 9100A (1968), Kenbak-1 (1971), and Altair 8800 (1975), are often cited as the first PCs. However, the Italian company Olivetti released the Programma 101 in 1965, which some historians believe to be the earliest "desktop personal computer."

Notwithstanding, this assertion that Programma 101 is the oldest PC is contested—a matter of definition and debate among historians. Both early competing computer models, the Hewlett-Packard 9100A and Programma 101, have no microprocessors nor operating systems—they look like glorified cash registers (my biased opinion).

The Altair 8800, an American model, does use an Intel 8080 microprocessor but had no operating system. Bill Gates and Paul Allen went on to write a programming language interpreter named Altair BASIC (1975) for this model, making it easier to write instructions in BASIC for the computer instead of in raw binary code.

Operating systems as we know it today wouldn't evolve until the middle to late 1970s when Gary Kildall invented the CP/M (Control Program for Microcomputers) and in the 1980s, MS-DOS was developed for computers and popularized by Microsoft. Later in 1980s and 1990s, Apple OS and Windows were introduced as operating systems with graphical user interfaces.

So, this last myth may actually be true, depending on the criteria of what constitutes a personal computer, e.g., presence of microprocessor, operating system, disk storage, monitor for output, keyboard for input, etc.

Final Remarks

Most historical myths do not survive because people are foolish. They survive because they are useful. A myth can make the past easier to remember—by glorifying or villifying certain people and elevating or concealing certain events. The trouble starts when the shortcut replaces the history.

Here are a few common warning signs:

• The story is too perfect

  If a quote or anecdote fits a famous person’s reputation too well, check and verify the source.

  
  

• The image feels theatrical

  Costumes, paintings, and movies often shape memory more than evidence does.

  
  

• The myth flatters the present

  Stories that make earlier people look stupid can hide what they actually knew.

  
  

• The detail has no clear source

  A claim repeated everywhere is not the same as a claim supported by evidence.

  
  

Good history often makes the story less tidy, but much more interesting. Cavemen showed ingenuity. The Romans knew how to put on a good show. Marie Antoinette was more than a fake quote. Washington's reputation was built from propaganda, as well as from his military and presidential roles.

The best way to handle history is to ask questions when a story feels too clean. Ask where the detail came from. Ask who benefited from repeating it. Ask whether art, politics, translation, or entertainment changed the memory. The real version is usually stranger, more random, and more imperfect than the myth.
