You’ve probably seen the movie The Duchess. Keira Knightley wears the massive hats, and Hayley Atwell plays the "best friend" who supposedly swoops in and steals the Duke. It’s a great drama.
But history is rarely that simple.
When people talk about Elizabeth Cavendish Duchess of Devonshire, or "Bess" as her friends called her, they usually treat her like a villain. The interloper. The woman who broke a marriage. Honestly? That’s a massive oversimplification of a woman who was actually one of the most intellectually curious and resilient figures of the Georgian era.
The Myth of the Homewrecker
Let’s be real. In the 1780s, if you were a woman without a husband and without money, you were basically invisible.
Bess didn't just walk into Devonshire House and decide to cause chaos. She was desperate. Her first marriage to John Thomas Foster was a total train wreck. He was abusive, he was unfaithful, and when they finally separated, he took her sons away. She didn't see her children for 14 years. Think about that for a second.
When she met Georgiana and the Duke in Bath in 1782, she was broke and broken.
People love to say she "lured" the Duke. But if you look at the letters, the bond between Bess and Georgiana was just as intense—if not more so—than her relationship with the Duke. Georgiana once wrote to her, "Do you hear the voice of my heart crying to you?" This wasn't just a mistress situation. It was a three-way emotional survival pact.
Life in the "Throuple"
The ménage à trois lasted for 25 years. That’s not a fling. That’s a life.
While the Duke (William) and Bess had two children together—Caroline St Jules and Augustus Clifford—they were all raised under the same roof as Georgiana’s kids. It sounds scandalous to us, but in the upper-class Whig circles of the time, "discretion" was the only real rule.

- The Duke: Quiet, obsessed with his dogs, and emotionally detached.
- Georgiana: Brilliant, charismatic, but drowning in gambling debt.
- Bess: Practical, cultured, and the glue that actually kept the household running.
Bess wasn't just a mistress; she was Georgiana’s closest confidante and the Duke’s constant companion. When Georgiana died in 1806, she actually made Bess her executrix. You don’t do that for someone you hate.
Why Elizabeth Cavendish Duchess of Devonshire Matters Beyond the Scandal
Most people stop the story when Bess finally marries the Duke in 1809. They think, "Oh, she won." But she only had two years as the official Duchess before William died in 1811.
What she did next is what actually makes her a legend.
She left England. London society was brutal to her after the Duke died—they called her a social climber and treated her like a pariah. So, she went to Rome.
The Archaeology Queen of Rome
While everyone else was busy gossiping, Elizabeth Cavendish Duchess of Devonshire was funding major archaeological digs. She wasn't just a "lady of leisure." She actually paid for the excavation of the Column of Phocas in the Roman Forum.
Before her, that area was basically a cow pasture called the Campo Vaccino.

She didn't just throw money at the dirt, either. She was deeply involved. She hung out with Cardinal Ercole Consalvi and the sculptor Canova. She published a fancy edition of Horace's Fifth Satire and translated books. She essentially reinvented herself as a powerhouse of the arts and sciences.
She proved that her identity wasn't just "the other woman." She was a scholar.
The Roman Legacy Nobody Talks About
Bess spent the last decade of her life in Rome, and she was genuinely respected there. In London, she was a scandal. In Rome, she was a patron.
She even helped restore diplomatic relations between the Vatican and the British Royal Family. That’s a huge deal for someone who started as a penniless exile. When she died in 1824, she was wearing a locket with a strand of Georgiana’s hair.
She never stopped loving the woman she supposedly "betrayed."

What We Can Learn from Bess
History is written by the people who survive, but it's also shaped by the people who are easiest to label. Bess is the "mistress" because it makes for a better movie.

But if you actually look at her life, she’s a study in resilience.
She navigated a world that gave her zero options. She survived the loss of her children, the loss of her reputation, and the death of her two closest friends. Instead of fading away, she built a whole new life in a foreign country and left a physical mark on one of the most famous historical sites in the world.
The next time you hear about the "scandalous" Duchess of Devonshire, remember the woman in the Roman dust, directing workers and translating Latin. She was way more than just a third wheel.
Actionable Insights for History Buffs:
- Check the Primary Sources: If you're near a major library, look for The Two Duchesses (published in 1898), which contains the actual letters between Bess and Georgiana.
- Visit the Forum: If you ever go to Rome, find the Column of Phocas. It’s not just a Roman monument; it’s a monument to Bess’s second act.
- Read Amanda Foreman: For the most balanced take, Foreman's biography of Georgiana is the gold standard for understanding the dynamics of Devonshire House.
The reality is that Elizabeth Cavendish Duchess of Devonshire lived a life of extreme highs and lows. She wasn't a saint, and she wasn't a monster. She was a woman who did what she had to do to survive—and then she decided to thrive.
