A Meeting in the Mud
On June 15, 1215, King John of England met a group of rebel barons in a meadow called Runnymede, on the banks of the River Thames. Surrounded by tents, guards, and the weight of near civil war, John affixed his seal to a document that would be known as Magna Carta.
It was not the first written law in the world, nor was it a constitution, but it was a binding agreement that placed limits on the king’s power and outlined specific rights for free men.
A King Under Pressure
John had earned the anger of the nobility by imposing exorbitant taxes and manipulating legal systems for profit. His military failures, including the loss of Normandy in 1204, worsened his position. To fund his campaigns, he charged huge fees for marriages, inheritances, and even access to royal justice.
He fell out with Pope Innocent III over the appointment of an archbishop, resulting in England being placed under a church interdict and John’s excommunication. In 1215, barons seized London and forced John into negotiations at Runnymede, mediated by Archbishop Stephen Langton.
The Document Itself
The charter was written in Latin, about 4,000 words long, and divided into 63 clauses. It promised the protection of church rights, limits on feudal payments to the Crown, and safeguards against illegal imprisonment.
Clauses 39 and 40 are among the most quoted: they protect the right to a lawful judgment and declare that justice will not be sold, denied, or delayed. At least 13 copies were made and sealed by royal scribes. Only four survive today—held by the British Library, Lincoln Cathedral, and Salisbury Cathedral.
Aftermath and Survival
King John never signed Magna Carta. Within weeks, he had it annulled by Pope Innocent III, claiming he had been coerced. War resumed almost immediately. John died in October 1216 of dysentery. His successors reissued the charter in slightly altered forms to regain political stability.
It was revised and reissued multiple times in the 13th century. A 1297 version was later purchased at auction for $21.3 million and is held at the U.S. National Archives. The British Library reunited the four 1215 copies in February 2015 for the first time in 800 years.
At a muddy riverside meadow in June 1215, King John faced off with rebel barons backed by armed knights.
Under threat of deposition, he sealed a detailed charter limiting royal authority.
It was a tense standoff that produced one of history’s most enduring documents…🧵👇 pic.twitter.com/g3u86j88uc
