A king out of money and out of allies
John had lost Normandy in 1204, taxed his barons heavily through scutage and arbitrary feudal fines to try to win it back, and been excommunicated by the Pope in a separate quarrel over who should be Archbishop of Canterbury. By 1215 a coalition of northern barons had taken up arms, renounced their homage, and occupied London itself, leaving John with almost no leverage left to bargain from and few loyal garrisons south of the Trent.
Runnymede was chosen because it belonged to neither camp: a flat water meadow between the royal garrison at Windsor and the rebel base at Staines, easy to reach by boat and impossible to fortify overnight. Negotiations over the charter's exact wording had been running for weeks before the sealing itself, conducted through intermediaries who shuttled drafts back and forth between the two armed camps.
Archbishop Stephen Langton had spent years in exile after his own dispute with John over the Canterbury appointment, and it was Langton, more than any baron, who is thought to have shaped the charter's language into something resembling a statement of legal principle rather than a mere list of grievances, drawing on earlier coronation charters and canon-law drafting he had studied in Paris.

Sixty-three clauses, most of them forgotten
Most of the document is not the ringing stuff of later legend. It fixes fish weirs on the Thames and the Medway, standard widths of cloth, the weights used for wine and ale, and the rights of the City of London to elect its own officials free of royal interference. It reads, in large part, like a settlement between a king and his wealthiest tenants over specific grievances of taxation, wardship and inheritance fees rather than a philosophical charter of liberty.
Two clauses outlasted the rest: no free man to be imprisoned, dispossessed or exiled except by lawful judgement of his peers or the law of the land, and to no one will the king sell, deny or delay right or justice. Those two lines are what later centuries, especially seventeenth-century parliamentarians battling the Stuart kings, built an entire tradition of due process and habeas corpus on top of, often reading far more into them than the barons of 1215 had intended.
A council of twenty-five barons was written in to police John's compliance, with the explicit power to seize his castles, lands and possessions if he broke the terms — a mechanism so hostile to royal authority that it, more than any single clause, guaranteed John would try to escape it the moment he found room to manoeuvre against the coalition that had forced his hand.
To no one will we sell, to no one will we deny or delay, right or justice.
Dead within the year
Pope Innocent III annulled the charter in late August, calling it 'illegal, unjust, harmful to royal rights and shameful to the English people' — he considered John his vassal, having accepted England as a papal fief the year before, and treated the barons' coercion of him as invalid under canon law. The First Barons' War broke out within weeks and dragged on past John's death from dysentery in October 1216, with French prince Louis invited by rebel barons to claim the throne itself.
The charter survived anyway, because John's nine-year-old son Henry III's regents, led by the elderly William Marshal, reissued a shortened version to win back baronial support and starve the French invasion of its domestic backing, and it was reissued again in 1225 as a condition of a new tax grant from Parliament. Those later reissues, not the 1215 original, are what entered English statute law and were still being cited in courtrooms centuries afterward.
Four parchment copies of the 1215 sealing are known to survive, held today at the British Library, Lincoln Cathedral and Salisbury Cathedral, each written in the cramped abbreviated Latin of a chancery clerk working against the clock rather than for posterity, and none of them identical in every clause to the others.
What everyone says
King John signed Magna Carta.
What the evidence says
Medieval kings authenticated documents with a wax great seal, not a signature, and John may have had limited need or occasion to write his own name at all. What survives from Runnymede are sealed copies distributed to cathedrals and county sheriffs, not a single signed original.
Twenty-five men and a broken promise
The security clause naming twenty-five barons as enforcers was the charter's most radical mechanism: if John broke the terms, any four of them could demand redress, and if he ignored that, the whole council could distrain his castles and lands with the backing of the wider baronage, a standing threat of legal rebellion written into the settlement itself.
Clause 39, on lawful judgement of peers, and clause 40, on selling or delaying justice, drew almost no comment in 1215 itself, buried among clauses about fish weirs and knights' fees. Their afterlife came later, cited by Edward Coke against the early Stuarts and eventually quoted in the American colonies as ancestors of due process and jury trial.
Pope Innocent III's bull annulling the charter, issued from Anagni within ten weeks of the sealing, condemned it as extracted by force from a vassal of the Holy See, which is precisely why the twenty-five-baron council never got the chance to test its power before war made the whole document moot.
