After betraying Leonidas by revealing the secret path at Thermopylae, Ephialtes fled to Thessaly, a region in northern Greece known for its pro-Persian stance. He likely stayed near or with the Persian army until their defeat at Plataea. This area initially offered him protection due to its political alignment.
Following his flight, the Amphyctionic League, an alliance of Greek city-states around Delphi, placed a bounty on Ephialtes’ head. His betrayal branded him infamous across Greece, making his life increasingly dangerous. The league sought to punish him for enabling the Persians to outflank the Spartans.
Later, Ephialtes moved to Antikyra, located on the northern shore of the Gulf of Corinth. This city was part of the Amphyctionic League, so he likely underestimated the risk. At Antikyra, he encountered Athenades, an exiled Thracian who recognized Ephialtes. Despite some unclear personal motives, Athenades assassinated him.
Herodotus reports that Athenades killed Ephialtes due to a personal grudge unrelated to the betrayal itself. However, the Spartans honored Athenades for avenging Leonidas and avenging the Greek defeat at Thermopylae. This suggests that Ephialtes’ death was seen as retribution within Greek society.
Herodotus briefly mentions this episode in his *Histories* (7.213–214) and notes alternative stories that claim other Greeks betrayed the path. He rejects these tales as less credible, partly because only Ephialtes had a bounty and because his killer received praise.

What Happened to Ephialtes After He Betrayed Leonidas?
After betraying King Leonidas at Thermopylae, Ephialtes’ fate took a dark and winding path, filled with flight, bounty, and ultimately, assassination. His story is a cautionary tale of betrayal that didn’t pay off in the long run and remains a vivid account in the annals of Greek history.
So, what really happened to the man who betrayed Leonidas? Let’s unpack this in detail.
Running for His Life: Flight to Thessaly
Immediately after the Battle of Thermopylae, Ephialtes skips out of the spotlight and heads north to Thessaly. Why Thessaly? Because it was one of the most pro-Persian regions in Greece at the time. It’s like going to a neighborhood that’s on your side after causing a huge mess. Smart move, right?
This move suggests Ephialtes likely stuck with the Persian army right up until their nail-biting defeat at Plataea. After that showdown, the Persian forces retreated through Thessaly, which temporarily made it a relatively safe haven for someone like Ephialtes who was on Persia’s side.
The Price on His Head: The Amphyctionic League’s Bounty
But safety didn’t last long. Ephialtes’ act of betrayal didn’t go unnoticed. The Amphyctionic League, a coalition of cities around the sacred site of Delphi, put a bounty on his head. Picture it: a network of Greek city-states actively hunting down one man.
This bounty was probably a big deal back then. It turned Ephialtes from a shadowy informant into a marked man. Things were definitely heating up for our infamous traitor.
False Sense of Security? Moving to Antikyra
In a move that seems a bit like poking the lion, Ephialtes later relocates to Antikyra—ironically a member city of the very Amphyctionic League hunting him. Strange choice, don’t you think?
Maybe Ephialtes thought enough time had passed or he believed he could blend in, but fate had other plans. Here’s the twist: another Greek, Athenades, also a fellow native of Trachis (just like Ephialtes), spots him.
The Deadly Confrontation and Motive
Athenades didn’t just recognize Ephialtes—he murdered him. Talk about a sudden end!
Herodotus—the ancient historian who gives us the clearest glimpse into these events—mentions that Athenades had a personal grudge against Ephialtes, though he never reveals what that was. I guess even ancient scandals had their mysteries.
Despite the personal grudge, the Spartans totally approved of Athenades’ action. They honored him for delivering vengeance against the man who betrayed their king. Vengeance was served cold, And served well.
Alternative Accounts: Was Ephialtes the Only Traitor?
Here comes a plot twist worthy of a historical novel. Herodotus also refers to an alternative story from the 5th century BCE where two unrelated Greek men allegedly revealed the clandestine path to the Persians.
However, Herodotus dismisses this as less believable. Why? Because Ephialtes was the only one with a bounty on his head, and his killer was honored—evidence pointing to his betrayal being uniquely infamous.
Interestingly, one of those other men was also from Antikyra—Ephialtes’ eventual place of death. Coincidence? Maybe. But this does show how murky and complex history can be.

The Historical Source: Herodotus’ Histories
If you want to dig into the primary source, most of what we know about Ephialtes comes from a concise but powerful slice of history in Herodotus’ Histories, specifically chapters 7.213-214.
Herodotus provides an invaluable window into the complexities of betrayal, loyalty, and revenge in ancient Greece. Without him, Ephialtes’ story might be just a footnote lost in time.
Why Does Ephialtes’ Fate Matter Today?
Ephialtes serves as an example of how betrayal, while it might yield short-term gains, often ends poorly. His story is not just about ancient wars but about trust, loyalty, and the consequences of crossing those lines.
Imagine if we applied this to modern life: would leaking secrets at work or betraying friends ever lead to a good end? Most likely not. Ephialtes’ outcome—a bounty, a life of fear, and violent death—reminds us that actions have consequences.
In this way, Ephialtes is more than a historical figure. He’s a reminder that treachery rarely leads to safety or honor.
Final Thoughts
So, after betraying Leonidas and the brave 300, Ephialtes runs north, tries to hide in enemy territory, becomes a marked man with a price on his head, and finally meets a violent end at the hands of someone with a personal vendetta. The Spartans, ever proud, honored his killer as a hero, sealing Ephialtes’ place in history as the ultimate traitor whose betrayal led to his downfall.
Isn’t it fascinating how one man’s choice changed the fate of an entire battle and ended with him living like a hunted fugitive? It’s a stark warning wrapped in an epic tale.
Next time you hear the name Ephialtes, remember: betrayal might open a door, but it often leads right into a trap.
