“Sometimes it’s because somebody’s so bad that they really make a dent in history,” Nancy Goldstone, author of “The Rival Queens,” a biography on de Medici, said. Goldstone talked to IndieWire via Zoom and explained that de Medici was not only a fierce strategist, but a brutal and bloody queen with a bevy of murders under her hat. “The Serpent Queen” attempts to showcase de Medici’s (Samantha Morton) ruthlessness, as well as highlight the humor in a story of an unappealing young Italian woman sent to France to become Queen. Filled with fourth-wall breaks, and a joke that feels pulled directly from Martin Scorsese’s “Goodfellas,” “The Serpent Queen” almost feels like the anti-historical drama. But sometimes fact and fiction collide — below, look at five elements “The Serpent Queen” returns to and how true (or not) they really are.

Unlike other Starz historical series where the goal is to show the two leads hopping into bed together, “The Serpent Queen” situates the relationship between young Catherine (Liv Hill) and Henry (Alex Heath) as one-sided. Catherine admits she fell in love with Henry, but the future King is enamored with the older Diane de Poitiers (Ludivine Sagnier). This is all true. Henry was a nice guy for the time period, per Goldstone. He was kind, attractive, and not brutal or mean. He also did come to trust Catherine very heavily. “She [Catherine] eventually wormed her way into being a friend,” Goldstone said. The biggest divergence from history with regards to the series’ central love triangle is Catherine’s relationship with Diane. The series presents it as two women in a power struggle. And while Goldstone said the two certainly weren’t friendly, each knew they needed the other to get ahead. Diane didn’t want Henry overthrown because of an illegitimate marriage, so she regularly forced him to do his “kingly duties” with Catherine — Catherine would bear 10 legitimate children for Henry. And Catherine understood Henry’s devotion to Diane so would feign being nice to her. In fact, it was this pseudo friendly relationship between the pair that made way for Catherine to become a power player in France. “When Henri dies,” said Goldstone, “The Guises [a prominent French noble family] they’re going to come in and take over. They have a choice. They can go with Diane, who has done so much for their family, or they can go with a little mouse, Catherine, who isn’t going to seem to be any trouble at all. But Diane is domineering and assertive. So they get rid of Diane and they put Catherine in there, and that’s her first step in coming forward in power.” Shanna Besson 3. Did Diane de Poitiers groom a young Henry II? Henry and Catherine’s ages aren’t mentioned in “The Serpent Queen,” but the pair married in 1533 when both were just 14 years old. In Kathleen Wellman’s book “Queens and Mistresses of Renaissance France,” Henry and Diane de Poitiers became romantically involved the year after he married Catherine de Medici; Henry was 15 and Diane was 35. But Goldstone said it’s not an example of what in present day we would understand as grooming. Though the two met when Henry was just 7, he idealized her as a representation of the ideal woman as well as his mother who had died, rather than a lover. “Diane was such a big thing,” said Goldstone. “In his mind, he kind of confused her with his mother and, of course, she was really beautiful. It wasn’t grooming, it was more on his side looking for his dead mother.” 4. Did Catherine’s court include little people and people of color? It’s unclear if the series takes liberties with Catherine’s court — including women of color like maid Rahima (Sennia Nanua) — but Catherine de Medici did routinely have little people in her court, as well as astrologers like Ruggieri (Enzo Cilenti). Goldstone noted Catherine de Medici was also a proponent of Nostradamus, the infamous astrologer who claimed to predict all manner of future events.
