Latest / Nero: Mad Tyrant or Misunderstood Emperor? — Fexingo History / Nero and Britannicus: The Poisoned Prince
Transcript
- Lucas: Luna, we've talked a lot about Nero's ambitions — his artistic tours, his building projects, his handling of the Great Fire. But today I want to go back to the very beginning of his reign, to a moment that set the tone for everything that followed: the death of his stepbrother Britannicus. Luna: Britannicus — that's Claudius's son by Messalina, right? Lucas: Exactly. And he was the rightful heir. Born in 41 AD, he was named Britannicus after Claudius's invasion of Britain. For the first years of his life, he was being groomed as the next emperor. But then Claudius married Agrippina the Younger, and she brought Nero — then called Lucius Domitius — into the imperial family, pushing Britannicus aside. Lucas: If today's conversation is giving you a clearer picture of how power really worked in imperial Rome, that's exactly what we're here for. And the way these episodes stay ad-free is listener support — you can find us at buy me a coffee dot com slash fexingo. It's a small gesture that keeps this going. Luna: Yeah, it's a way to keep the history flowing without interruptions. Lucas: So Britannicus was a constant threat to Nero's position, even after Nero became emperor in 54 AD. He was only about thirteen when Nero took power, but he was a living symbol of the Claudian line. And there were people in the Senate and the Praetorian Guard who saw him as a possible alternative to Nero, especially if things went wrong. Luna: So he was a rallying point for opposition. Lucas: Exactly. And Agrippina, Nero's mother, was acutely aware of this. She had already sidelined Britannicus's tutors and replaced them with her own loyalists. But the real crisis came in early 55 AD, just months into Nero's reign, when Britannicus suddenly died during a dinner party. Lucas: The accounts we have — from Tacitus, Suetonius, and Cassius Dio — all agree it was poison. The story goes that Nero hired a notorious poisoner named Locusta to prepare a fast-acting toxin, and it was administered to Britannicus in his wine. The boy collapsed immediately, and Nero calmly remarked that it was just an epileptic seizure — Britannicus was known to have epilepsy. Luna: Wait — Locusta? That's the same woman who later helped Nero poison Agrippina? Lucas: The same one. She was a professional poisoner, a kind of specialist in political assassinations. She'd already served time for poisoning but was kept on retainer by the imperial household. After Britannicus's death, Nero rewarded her with a full pardon and even had her train apprentices. Lucas: But here's the thing: the murder of Britannicus wasn't just about eliminating a rival. It was a signal. Nero was showing that he would not tolerate any challenge to his authority — even from a fourteen-year-old boy. And it drove a wedge between Nero and his mother. Luna: Why between them? Agrippina was the one who pushed Nero forward. Lucas: Yes, but she had also been using Britannicus as leverage. Tacitus says that after Nero became emperor, Agrippina began to threaten him — hinting that she could support Britannicus if Nero didn't do what she wanted. So by killing Britannicus, Nero was cutting off her ability to manipulate him. It was a direct challenge to her influence. Lucas: And the aftermath is telling. Britannicus was given a public funeral, but the body was cremated hastily, and the rites were minimal. No procession, no eulogy — just a quick disposal. That suggests the court was trying to avoid drawing attention, but it also fed the rumors of foul play. Luna: Did anyone openly accuse Nero? Lucas: Not directly. The sources say that the Senate and the people largely accepted the epilepsy story, at least publicly. But privately, everyone knew. And there was one figure who made his feelings clear — Seneca, Nero's tutor and advisor. He's said to have written a pamphlet, now lost, called 'On the Death of Claudius' that satirized the old emperor's deification. But about Britannicus, he was silent. That silence spoke volumes. Lucas: What's fascinating is the contrast with Nero's later crimes. The murder of Britannicus was his first major act of dynastic violence, and it was cold, calculated, and effective. But it also set a precedent. Once you've killed your own stepbrother, it becomes easier to kill your mother, your wife, anyone who stands in your way. Luna: So in a way, Britannicus's death was the point of no return for Nero. Lucas: I think so. It established his ruthlessness and his willingness to use poison — the most insidious of weapons. And it isolated him from the one person who had always protected him: his mother. Within a few years, Agrippina herself would be dead, and Nero would be truly alone. Luna: Let's talk about Locusta for a second. What do we know about her? Lucas: She's a shadowy figure, but she appears in multiple sources. She was a poison specialist, probably from Gaul or somewhere in the western provinces. She was condemned to death earlier in Claudius's reign but was reprieved and kept in custody — useful for when the imperial family needed someone with her particular skills. After Britannicus, Nero had her freed and even gave her a villa in the countryside. Lucas: Her story is a reminder that imperial politics often relied on specialists who operated outside the law. She's a kind of dark mirror to the doctors and architects we've talked about in other episodes — a professional whose craft was death. Luna: And she wasn't the only one. There were whole networks of poisoners in Rome. Lucas: Absolutely. But Locusta is the most famous because she was directly employed by the emperor. She even survived Nero's fall — we hear of her later training new poisoners under Galba. So she was a kind of institution in her own right. Lucas: Back to Britannicus: his death had long-term consequences. It solidified Nero's position, but it also alienated the Claudian loyalists, some of whom later joined the Pisonian Conspiracy. And it made the Praetorian Guard more wary — they had to decide where their loyalties lay. Luna: How did the Praetorians react? Lucas: Initially, they were bought off. Nero increased their pay and distributed donatives. But the memory of Britannicus lingered. When Nero finally fell in 68 AD, one of the first things the new emperor Galba did was to execute Locusta and dismantle her operation — as if to symbolically sever Nero's legacy. Lucas: So Britannicus is a tragic figure — a boy who was born to be emperor but was shoved aside and killed before he could even become a man. His story is often overshadowed by Nero's more spectacular crimes, but it's the key to understanding how Nero held power in those early years. Luna: It really sets the stage for everything that came after. Lucas: Exactly. And it shows that from the very start, Nero was willing to do whatever it took to secure his throne — even if it meant poisoning his own family.
