Charles II was bored. He was broke. He was arguably the most charismatic man to ever sit on the English throne, and honestly, he was a bit of a disaster when it came to his personal life. History books usually give him the nickname "The Merry Monarch." It sounds fun. It sounds like he just threw a lot of parties after the grim, soul-crushing years of Oliver Cromwell’s Puritan rule. But the reality of King Charles II mistresses is a lot messier, more expensive, and infinitely more politically dangerous than the "merry" label suggests. These weren't just "side pieces." They were power brokers who controlled access to the King, influenced foreign policy with France, and cost the taxpayer a literal fortune.
We aren't talking about a few quiet flings here. Charles had at least 14 acknowledged illegitimate children. He had a wife, Catherine of Braganza, who sadly couldn't provide an heir. This void was filled by a rotating cast of women from every social strata imaginable. From the aristocratic Barbara Villiers to the "Protestant whore" Nell Gwyn, these women created a shadow court.
Why the King Charles II mistresses held all the cards
If you wanted a job in the 1660s, you didn't go to the King first. You went to his bedroom door. Specifically, you went to whoever was currently occupying it.
The most terrifying of them all was Barbara Villiers, also known as Lady Castlemaine. She was high-born, incredibly beautiful, and had a temper that could level a building. For the first decade of the Restoration, she was the "uncrowned queen." She didn't just want the King’s affection; she wanted his money and his political submission. She was known to scream at Charles until he gave in to her demands. Once, when she feared she was losing her grip on him, she allegedly threatened to print his private letters and burn his palaces down. Charles, being Charles, usually just bought her more jewelry to shut her up. He gave her the Title of Duchess of Cleveland. It wasn't just a name; it came with lands and a massive income.
Then you have the international drama. Enter Louise de Kérouaille. She was a French spy. Basically.
Sent by Louis XIV to keep the English King leaning toward French interests, Louise was the total opposite of Barbara. Where Barbara was loud and violent, Louise was "the baby face" who used tears to get her way. The English public hated her. They saw her as a Catholic threat and a puppet of the French crown. She was the one who managed to stay in favor the longest, eventually becoming the Duchess of Portsmouth.
The People's Favorite: Nell Gwyn
You can't talk about this era without Nell. She’s the legend. She started out selling oranges in the theater and ended up in the royal bed.
- The "Protestant Whore" Incident: This is a real thing that happened. A mob once surrounded her carriage in Oxford, thinking it was the Catholic Louise de Kérouaille inside. Nell stuck her head out the window and shouted, "Pray, good people, be civil; I am the Protestant whore!" The crowd cheered. She was hilarious.
- The King's dying wish: Charles actually cared about her. On his deathbed in 1685, one of his last recorded requests to his brother, the future James II, was "Let not poor Nelly starve."
- The Chelsea Pensioners: Legend says she persuaded Charles to build the Royal Hospital Chelsea for wounded soldiers. Whether she did or not, she remains the most sympathetic figure of the bunch.
The Economics of Royal Infidelity
It’s easy to look at this as a soap opera, but the financial impact was staggering. Charles was constantly asking Parliament for money. Parliament was constantly asking why that money was being spent on diamonds for the Duchess of Cleveland’s children.
The King was essentially subsidizing a parallel royal family. His illegitimate sons were given dukedoms—Grafton, Richmond, St Albans, Monmouth. These titles weren't just honorary; they involved massive transfers of wealth and land that stayed in those families for centuries. If you look at the British aristocracy today, many of the top-tier dukes are direct descendants of King Charles II mistresses.
It created a massive PR problem. While the King was negotiating the Treaty of Dover (a secret deal where he took French money to eventually convert to Catholicism), his mistresses were flaunting wealth that the average Londoner—still recovering from the Great Fire of 1666 and the Plague—couldn't fathom. It was a recipe for revolution, yet Charles somehow survived it. He had a knack for being likable even when he was being completely irresponsible.
The Sad Reality of Catherine of Braganza
We have to mention the actual Queen. Catherine was a Portuguese princess who arrived in England not speaking the language and finding out her husband’s head mistress (Barbara Villiers) had been appointed as her "Lady of the Bedchamber."
Imagine that for a second.
Catherine initially refused. She fainted when Barbara was presented to her. She cried. She fought. But Charles was firm. He insisted his mistress be part of the Queen's inner circle. Eventually, Catherine gave up. She even became somewhat friendly with some of them. She suffered multiple miscarriages, which made her position precarious because she couldn't provide a legitimate heir. This meant Charles’s brother James was next in line, which everyone hated because James was an overt Catholic.
The presence of the mistresses wasn't just a personal insult to Catherine; it was a constitutional crisis in the making.
What happened to the kids?
The children of these mistresses didn't just disappear into the background.
- James Scott, Duke of Monmouth: The son of Lucy Walter (a pre-Restoration mistress). He eventually led a rebellion to try and take the throne from his uncle. It ended with his execution.
- The Duke of Richmond: Son of Louise de Kérouaille.
- The Duke of St Albans: Son of Nell Gwyn.
These men became the backbone of the "new" nobility. They were the physical evidence of the King’s inability—or refusal—to follow the moral codes he was supposed to uphold as the Head of the Church of England.

How to trace this history today
If you’re interested in the tangible legacy of these women, it’s surprisingly easy to find. You don't need a time machine. You just need a ticket to a few National Trust sites or a walk through London.
First, check out the portraits. Peter Lely, the court painter, spent half his career painting these women. You can see them in the National Portrait Gallery. They all have that specific "Lely look"—heavy-lidded eyes, voluminous hair, and a look of total boredom that was very fashionable at the time.
Second, look at the geography of London. The area around Pall Mall and St. James's was the playground for these women. Nell Gwyn’s house was at 79 Pall Mall. She famously refused to be a tenant of the King, demanding the freehold because she "had always conveyed her favors on the freehold." He gave it to her.
Lessons from the Restoration Court
The era of King Charles II mistresses teaches us that power is rarely where it looks like it is. On paper, Charles was the absolute monarch. In reality, he was managed, manipulated, and navigated by a group of highly intelligent, often desperate women who knew that their security depended entirely on their ability to keep the King’s attention.

It wasn't just about sex. It was about survival. In a world where women had no legal rights, no right to own property independently, and no political voice, the "mistress" route was a valid, albeit risky, career path.
Actionable ways to explore this further:
- Visit Ham House: This is one of the best-preserved 17th-century houses in Europe. It gives you a real sense of the claustrophobic, opulent, and gossip-fueled atmosphere of the Restoration.
- Read the Diary of Samuel Pepys: Honestly, if you want the "tea" from 1660, Pepys is your guy. He was obsessed with Lady Castlemaine. He writes about her laundry hanging out to dry and how much he wanted to just look at her. It’s the closest thing to a 17th-century tabloid.
- Track the Dukedoms: Research the current Duke of Richmond or the Duke of Buccleuch. Their family trees lead straight back to the bedrooms of Whitehall Palace.
- Study the "Popish Plot": Look into how the mistresses were used as scapegoats during the anti-Catholic hysterias of the 1670s. It shows how the personal lives of the royals were weaponized for political gain.
The story of Charles II isn't a romance. It’s a study in power, excess, and the complicated ways that human desire shapes the borders and laws of nations. Most people think of kings as untouchable figures, but Charles’s life shows they were often just men trying to keep several very powerful, very angry women happy at the same time. He failed at it constantly. And that makes the history much more interesting.
