Dan Snow and historian Dr. Rebecca Warren dive deep into the roots, process, and aftermath of this seismic rupture in British history.

Key Discussion Points & Insights
1. The Origins of the Crisis
[04:19 - 07:05]
- Longstanding Tensions: Charles I ascended the throne in 1625. Friction with Parliament escalated, resulting in his ruling without them for 11 years.
“King Charles I comes to the throne in 1625, falls out with Parliament really badly, rules without them for 11 years until 1640, has to call Parliament again because he needs some money.” (Rebecca Warren, 04:22)
- Civil War Erupts: Attempts at reconciliation break down. The result is civil war beginning in 1642—an outcome at first unimaginable for most participants.
“Nobody fights the Civil War… thinking they want to cut the head of the King… What they want to do is to force the King into a position where he will reform … and reach a settlement with them.” (Rebecca Warren, 05:09)
- Fractures Within Parliament/Army: After Parliament’s victory, the anti-royalist alliance splinters. Parliamentary moderates want a settlement, while elements within the army demand justice and distrust both Charles and Parliament.
2. The Legal Quandary of Trying a King
[07:05 - 11:52]
- Who Can Judge the Sovereign?: The era’s legal theory placed the King above the law—as the “font of justice.” The trial posed unprecedented legal and constitutional challenges.
“The essential understanding … at this time is that all justice comes from the King … So treason is against the sovereign, but he is the sovereign.” (Rebecca Warren, 07:17)
- Army’s Intervention: In December 1648, the army purges Parliament (“Pride’s Purge”) to exclude those who might settle with Charles.
- Shifting the Concept of Sovereignty: Parliament’s legal workaround reframed sovereignty as residing with “the people” (represented by Parliament), and the king as their servant.
“The argument is somewhat turned on its head to say, actually the sovereign is the people and the people are represented by Parliament…” (Rebecca Warren, 08:53)
- A Forgotten Revolution: Rebecca and Dan underscore the radical nature of these ideas, even if later sidelined by the restoration.
“It is a truly, I think, revolutionary argument and a truly revolutionary moment…in 1660, the monarchy is restored and everybody kind of clamped down on this idea.” (Rebecca Warren, 10:00 & 10:49)
3. Setting Up the Trial
[11:52 - 14:01]
- Westminster Hall: Chosen for its legal resonance, site of many prior treason trials (e.g. William Wallace, Guy Fawkes).
- Who Sits in Judgment?: Commission of 135, though only about 50–60 actively attend; legal heavyweights largely absent, mid-ranking figures like John Cook (prosecutor) and John Bradshaw (president) preside.
“One of the difficult things for Parliament is that some of the senior legal minds…have scuttled off…they don’t want to be associated with this…” (Rebecca Warren, 12:32)
4. The Trial: Day by Day
Day 1: 20th January 1649
[16:10 - 17:54]
- Charles appears dressed in black, refuses to recognize the court’s legitimacy or plead. He’s accused of tyranny, maliciously levying war, inviting foreign activism, and placing self above the realm’s welfare.
“He point blank refuses to recognise the legality of the court.” (Rebecca Warren, 17:28)
Day 2 & 3:
[18:31 - 21:30]
- Charles maintains silence; the court struggles, as trials require a plea. They hope to extract participation, but he refuses, denying the court—and thus Parliament—the legitimacy they crave.
Day 4: Hearing Witnesses
[24:23 - 25:18]
- Witnesses are privately heard to add a semblance of legal process.
Day 5: Verdict
[25:18 - 26:03]
- With Charles refusing to plead, evidence is read publicly, then he’s found guilty.
“There are only so many days you can spin that out.” (Rebecca Warren, 25:47)
Day 6-7: Final Appeals and Sentence
[26:08 - 27:52]
- Close friends’ last-ditch appeals fail. On January 27th, the death sentence is pronounced—Charles is “dead in law” and not permitted to speak further.
5. Execution and Legacy
Execution Day: 30th January 1649
[33:49 - 40:14]
-
Dressing for Martyrdom: Charles wears two shirts to avoid shivering, maintaining stoic martyr imagery.
-
Final Hours: Walks through his art-filled gallery en route to the scaffold. Parliamentary leaders rush to pass stopgap legislation to prevent immediate proclamation of Charles II.
-
The Execution: On the scaffold, Charles proclaims innocence, reaffirms Christian faith, and reportedly says, “I go from a corruptible crown to an incorruptible one.” He is executed with a single blow.
“He says…‘I go from a corruptible crown to an incorruptible one.’” (Rebecca Warren, 38:46)
-
Public Reaction: An audible groan rises from the crowd; some try to collect relics, dips in royal blood.
“Such a groan went up as this young lad had never heard before and hopes never to go again.” (Rebecca Warren, 40:14)
-
Burial: Quiet, at Windsor; Anglican rites forbidden, but Bishop Juxon refuses to improvise substitute prayers—showing the deep and unresolved religious rift.
6. The Political and Symbolic Aftermath
[41:46 - 44:41]
- Martyrdom and Myth: “Icon Basilike” (allegedly by Charles, likely written by John Gauden) cements the cult of the martyred king. The myth endures long after the monarchy’s return.
“[The book] goes through 35 editions in the first year…This creation of this myth of the martyr king really takes off.” (Rebecca Warren, 42:29)
- Why Restoration? Despite the myth, Rebecca argues restoration was spurred more by political pragmatism and a lack of workable alternatives than royalist sentiment per se.
“What matters more is that the model of a king and parliament as the right way to govern…is really the only one that everybody understands.” (Rebecca Warren, 44:26)

On historic erasure:
“It really does show how history is written by the victors, that this was managed to be… squashed out of our history.”
