Tyrannicide Brief: he sent Charles I to die

Read Tyrannicide Brief: Story of the Man Who Sent Charles I to the Scaffold by Geoffrey Robertson. Charles triggered the tragic civil wars (from 1642) when 1 in 10 Eng­lish­men died. But in 1649, Parliament struggled to find a law­yer with guts to pro­secute a king who claimed to be above the law.

In the end, they chose the radical lawyer John Cooke (1608–60) whose Pur­it­an consc­ience, pol­itical vis­ion and love of civil liberties made him stand out. Cooke might have been just an average lawyer but he was an impressive reformer. Robertson said that in the 1640s, Cooke had been the first to assert that poverty was a cause of crime. Cooke was already arguing for: a nat­ional health service; a national legal serv­ice; end most capital punishment; probation for those who stole out of hunger; and an end to the use of Latin in court.

Cooke was a criminologist who wrote frequently. Ev­ery­thing that came off the presses in this 1640-60 era was collected and placed in a special room in the British Library, in­cluding all the transcripts of the trials and public­at­ions. Robertson gave the Puritans the credit for the good years, all the more note­wor­thy because they had suff­ered the king’s destruction of their relig­ious beliefs. Some left for the USA, but those who remained for­ged a belief in the literal Bible and in Magna Carta, civil liberty and bills of rights. Robertson was most impressed with their fierce belief in civil lib­er­ties, but I was not. Where was the historical evidence?

What the Puritans achieved in the 1640s was the abolition of Star Ch­am­ber. They created the principle of no taxation without repres­en­t­­­at­ion, and were keen on the separation of church and state. They fought in the civil wars that the king started. The king was also guilty, as Cooke later showed, of supervising torture of prisoners of war, and of encouraging plunder by the royalist forces.

In 1649, after Oliver Cromwell's army took Charles I pris­­on­er, the new regime had to decide what to do with the king. They could have killed Charles, but a fair trial was seen as more ethical. Cooke was asked to prosecute him, esp after other suitable lawyers hid away from their Inns of Court.

In Par­liament's brief to Cooke, the judge had to end the immunity of the head of state. But the divinely appointed king WAS the law, so prosecuting him seemed impossible. Thus Cooke had to invent the crime of Tyranny (aka War Crimes today). He put Charles on trial in Jan 1649, charging him with abolishing peop­les’ civil liberties and with mass murd­er­ing citizens. In Westmin­ster Hall, as this improbable trial was starting, the king was brought in and Cooke delivered the charges.

John Cooke

The king did the right thing at his trial, asking by what lawful auth­ority the state disregarded sov­ereign imm­unity and put a king on trial? Cooke answered that, be­cause there were certain crimes that were so heinous they dimin­ished the whole state, a king COULD be put on trial.

The decision to execute the king was the judges to make, but perhaps they didn’t predict that the executed royal would become a martyr. King Charles I was taken to the scaf­f­old and beheaded later in Jan 1649, and for the next ten years he was remembered kindly. Executing him only inflamed the civil war further.

Cromwell appointed Cooke as a reforming Chief Justice in Ireland where of course he made very progressive rulings. Naturally the wealthy land-owning lords hated Cooke.

In 1653, at the head of an army, Oliver Cromwell marched into Parliam­ent and dis­mis­sed the members.

King Charles II returned from France in 1660 and the monarchy restored. Cooke was the very first to be arrested, suff­ering a rigged trial at the Old Bailey when Charles II avenged his father. The ex-judge was taken to Charing Cross and made a very fine gallows speech: 'We are not traitors; we would have secured the lib­erty of the people and the whole groaning creation if the country had not pref­er­red servitude to freedom.' He was hung, drawn and quartered.

Cooke and other regicides were executed. Cooke’s heart and genit­als were fed to street dogs, and his head was shown at West­min­ster Hall. Samuel Pepys travelled to see some of Cooke's colleagues executed, but found that the exec­ut­ions had been sus­pended. App­ar­ently Charles II’s advisors saw the crowd turning nasty. They would have to detain republicans without trial, despite the fact that habeas corpus laws were in place. So it was decided to put all the repub­lic­ans on off-shore islands (eg Jersey) where habeas corpus wouldn't reach. Does this remind us of Guantanamo Bay?

Conclusion The key years 1640-60 was an era when extra­ordinary prog­ress was made in human rights. The sovereignty of parl­iament, indep­end­ence of the jud­ges, separation of church and state all go back to this short, important era.

The Hon Michael Kirby believed that the King Charles' trial was by legal stand­ards a dis­creditable affair. This seemed indisputable, until Robertson dug out a very old edition of the State Trials. Rob­ert­son was surpris­ed to find that Charles’ trial was far from discreditable - on the con­trary it app­eared for its time as an oasis of just­ice and fairness."

Rob­ert­son said Cooke's trial was actually the dis­cred­it­able affair. The defendants had been locked up for months in plague-filled prisons, and were brought to the Old Bailey in leg-irons to be viciously taunt­ed by pro-Charles II judges. The Cooke events, Robertson proposed, showed that a person was more likely to get a fair trial in a repub­lic­an court, than in a monarchical court. And provided a model for modern trials of criminal national leaders. 

The devil sits with 11 men: 9 regicides and 2 chaplains who supported Charles I's execution

Robertson showed that some important 1640s men have been white­washed out of history by British historians, both conservative and liberal, for pol­itical reas­ons. These extra­ord­inary men, who had taken on King Charles I, were later ex­ec­ut­ed at the Old Bailey in 1660. Thus Robert­son concluded that the king’s execution was necessary to est­ab­lish Parl­iament's sovereignty and that the regic­ide trial victims should be seen as national heroes. I can agree with his first conclusion but his second conclusion sounds like a barrister, not like an historian

In 1587, law, history and fact had been twisted to argue that a Scottish monarch owed the English monarch a duty of obedience. It had allowed Mary to be found guilty of treason against her Tudor cousin, Elizabeth I.

Now law, history and fact were being twisted again to argue that a king could commit treason against his people. It smacked of victors’ justice. The Scots had sent official delegations to plead for his life. So had the French. The Dutch had done so too: Mary, Princess of Orange, was Charles’s eldest daughter. But their pleas had been to no avail.

Why did Robertson call his book Tyrannicide Brief?

Boa noite minha querida amiga Helen. Obrigado pela excelente matéria e aula de história. Desejo uma excelente noite de quarta-feira em Melbourne e para todos os seus familiares e um grande abraço do seu amigo carioca.

I am really very surprised that ideas like poverty causing crime,probation for those stealing out of hunger and a national health service were around in the 1600s. I wouldn't have guessed those ideas would exist until at least the 1800s.
I am also appalled that these ideas are STILL not fully accepted 400 years on.
The most powerful country in the world doesn't afford it's citizens health care, people are still punished for crimes committed in poverty: a small boy killed when his mother stole diapers comes to mind.

I haven't thought about Geoffrey Robertson in some time.
Thank you

I enjoyed learning more English history. That would be the Geoffrey Robertson, former husband of Kathy Lette? I used to love the way he pranced in the television show, Hypotheticals.

Thank you. You noted that the authorities who ordered beheading were afraid: worried how the people of London would react when the grim ritual of the execution was enacted. Already there had been widespread anger expressed against the King's trial.
So I don't suppose we will ever know what proportion of the population supported or opposed execution - Royalists and all the nations you mentioned opposed killing the king; most Puritans, Cromwell, the army, judges and Parliamentarians supported it.
The tide turned, of course. Charles' executioner beheaded the King in 1649 and 6 months later, the executioner was in turn executed.

Tyrannicide is the killing or assassination of a tyrant or unjust ruler, often for a perceived common good, and often by the tyrant's subjects. Since The Tyrannicide Brief is about John Cooke, a heroic, conscientious, reforming lawyer, selected by parliament to prosecute the trial of Charles I, we can assume the book's title was not being brutal about Cooke, the court and the entire execution process.

it was an important part of history for the entire British Empire, and possibly left a legacy for other parts of the world as well. Are you familiar with Geoffrey Robertson, an Australian barrister-broadcaster-academic who has done most of his famous work in the UK.

Watching Geoffrey Robertson on tv was always an impressive experience, but this was the first book I have read of his. I am recommending this barrister's book to you because he wrote about the 1649 trial as the world's first prosecution of a king for tyranny. Even though I oppose capital punishment totally, I think his legal analysis was very important.

Hels said...

Andrew
the very same couple, yes :) The only thing that surprised me about Kathy's career was that she wrote and published more international bestsellers than Shakespeare.
If she was writing about history, I imagine she'd choose feminist and/or social history.

River said...

Probably not a book that I would want to dive in to.

This book grew out of a commentary the author offered on a lecture this reviewer gave on the defects of King Charles' trial. He was intrigued as to why Cooke was not celebrated as one of England's most famous advocates. At first, Robertson was inclined to ascribe this to the truth that, in any great historical cause, victors tend to put their spin on history.
But then Robertson saw qualities in Cooke that deserved a biography. The result is readable, recounting the beginnings of limited government in English speaking countries. Robertson showed the trial of King Charles was the forerunner to the modern efforts to make tyrannical rulers accountable to the people they have oppressed.

Hels said...

River,
me either, usually. I hate death sentences by accident, disease or war, let alone by lawful execution. But I was very interested to see what an Australian-British barrister would write about a king committing treason against his people.

Hels said...

Justice Michael Kirby
the book certainly did recount the beginnings of limited government in English speaking countries, including Australia. Since the Governor General carries out the monarch's royal duties in Australia, would Robertson have approved of overthrowing the lawful Australian prime minister, Gough Whitlam?

It was a fascinating period in history. "Uneasy lies the head that wears a crown,'

roentare said...

I knew very little about this period of history, so I found your review both fascinating and informative. It certainly sounds as though Robertson presents a strong case, although I am not sure I would go as far as calling the regicides national heroes.

Oh the politics of it all, Hels. People were barbaric in those days.

The immense pressure carried by politicians and church leaders etc meant they had to make permanent decisions that influenced the entire nation. It could not have been easy!

But in this case the most responsible people were VERY uneasy because they didn't know who supported them, who opposed them and who wanted them dead. Even the judges who tried Charles I and had him executed may have feared they too would be dead, as soon as community views swung around the other way.

And not just kings. Sir Thomas More (1478-1535) was a lawyer, scholar, Parliamentarian and Chancellor under King Henry VIII. He was executed in July 1535 for refusing to accept Henry as the Supreme Head of the Church of England!

Hels said...

Margaret
barbaric is the word that comes to mind when we think of King Henry VIII, yes. When his wife Anne Boleyn gave birth to a daughter but suffered multiple miscarriages, Henry didn't get a son. So he had his wife accused of treason and incest, and had her beheaded in 1536. What a beast :(

After King Charles I was executed in 1649, legislation changed radically. Parliament abolished the monarchy and the House of Lords, transforming England into the Commonwealth of England Republic. But how long did these legislative changes last?
Not long! King Charles II returned from exile in 1660, ending 11 years of military rule in an event called the Restoration. The strict Puritanical laws of Cromwell's Commonwealth ended and the English public celebrated passionately.

Mandy said...

What a fascinating article. You make such a good point about the establishment of tyranny laws and the later evolution to war crimes legislation. It's also so interesting how much of our current rights and freedoms stems from the Charles I trial

Jo-Anne's Ramblings said...

I found this interesting, as I didn't know most of this and as you know I like learning about history

Hels said...

Jo-Anne
me too :) But I love history blogs in particular because they are more honest than our school and university teachers when analysing British history.

Hels said...

Mandy
I am not sure that our current rights and freedoms stem directly and exclusively from King Charles' trial and execution. But I do believe the issues raised then DID create critically important debates openly for the first time.

How did I miss so many interesting posts? I particularly found this interesting as Cooke was a Puritan, and of course so many Puritans came to Massachusetts. And that's where the American Revolution more or less started. I'm not sure they were Puritans then, but I k now a lot of their laws were still in that state (having grown up there.) I didn't know these Puritans were into so many other fights. Thanks for sharing this.
