This Day in History — John Scopes Is Found Guilty
On this day in 1925
On July 21, 1925, a Tennessee jury found substitute teacher John Scopes guilty of teaching evolution in nine minutes of deliberation — ending a trial that had transformed a small Appalachian town into the center of a national debate over science, faith, and academic freedom.

"Sometimes a trial is strictly about one defendant on the stand. Other times, the defendant is merely the catalyst for a battle over the soul of a culture."
On this day in 1925, 24-year-old high school coach and substitute teacher John T. Scopes was found guilty of violating Tennessee's Butler Act, which made it a crime to teach human evolution in any state-funded school. The verdict took the jury roughly nine minutes to reach. It had taken the country considerably longer to arrive at the moment.
The trial itself had been cooked up weeks earlier over cold drinks at Fred Robinson's Drugstore in Dayton, Tennessee. Local businessmen, eager to boost their quiet town's struggling economy, had read an ACLU notice offering to support any teacher willing to challenge the Butler Act in court. They convinced the mild-mannered Scopes — who was filling in as a substitute biology teacher — to serve as the test case. Scopes was so uncertain whether he had even covered the evolution chapter that he had to check his own textbook notes before agreeing.
What followed was anything but quiet:
A Media Blitz: Chicago's WGN Radio broadcast the proceedings live — the first national broadcast of a trial in American history. Hundreds of journalists descended on Dayton. The town transformed overnight: souvenir vendors, street preachers, and at least two performing chimpanzees set up on the courthouse lawn, one of them dressed in a fedora and spats and presented to crowds as evolution's "missing link."
The Courtroom Moves Outside: On July 20, the day before the verdict, the heat inside the packed courthouse reached over 100 degrees and Judge Raulston grew concerned the weight of the spectators might collapse the second-floor floorboards. He moved the trial's most pivotal session outdoors onto the courthouse lawn — and it was there, under the shade of oak trees and in front of thousands of onlookers, that Clarence Darrow called William Jennings Bryan to the witness stand.
Darrow's Gambit
Bryan was no ordinary prosecutor. A three-time Democratic presidential nominee and one of the most celebrated orators in America, he had agreed to join the prosecution as a defender of the faith. Darrow's move — calling Bryan as an expert witness on the Bible itself — was legally unprecedented and tactically brilliant. For two hours, under the open sky, Darrow pressed Bryan on the literal interpretation of scripture: the age of the Earth, the story of Jonah, the date of the great flood. Bryan struggled. The crowd, initially sympathetic to him, grew restless.
The next morning, July 21, Judge Raulston struck Bryan's testimony from the record entirely, ruling he had gone too far in permitting it. Then came Darrow's final maneuver: he asked the jury to return a verdict of guilty.
Under Tennessee law, only a not-guilty verdict would have allowed Darrow to make a closing argument — which would have triggered Bryan's right to respond with the elaborate closing speech he had been preparing for weeks. By requesting guilty, Darrow denied Bryan his platform. The jury complied in roughly nine minutes.
Scopes was fined $100 — the minimum allowable amount. He then rose and made the only statement he had offered during the entire proceedings: that he intended to continue opposing the law in any way he could, that any other action would violate his ideal of academic freedom, and that he considered the fine unjust.
Five days later, William Jennings Bryan took a nap in Dayton after an enormous dinner and never woke up. When reporters told Clarence Darrow that Bryan had died of a broken heart, Darrow replied: "Broken heart nothing — he died of a busted belly."
The Aftermath
The ACLU appealed. Two years later, the Tennessee Supreme Court upheld the Butler Act's constitutionality but overturned Scopes's conviction on a technicality — the judge, not the jury, had set the fine. That technicality prevented the case from ever reaching the U.S. Supreme Court, exactly as the state intended.
The Butler Act remained on Tennessee's books until 1967. By then, the Scopes Trial had already become one of the defining cultural landmarks of the twentieth century — not for what it decided legally, but for what it exposed about the fault lines running through American life.
"The verdict came, the gavel fell,
Yet questions lived beyond the cell…
For laws may silence lessons taught,
But cannot stop the march of thought."
History reminds us: the Scopes Trial was not simply a legal dispute over a single biology lesson. It was a mirror held up to a nation in the middle of deciding what kind of country it wanted to be — and the reflection it caught, of science and faith and power and ridicule colliding in a sweltering Tennessee courtroom, has never fully faded.
