King John sealed Magna Carta at Runnymede on 15 June 1215 the way a man signs a ransom note, under duress, with every intention of tearing it up the moment the immediate danger passed. He very nearly managed it. Within ten weeks he had persuaded Pope Innocent III, his own feudal overlord in a technical but real sense since John had submitted England as a papal fief in 1213, to annul the charter outright as an affront to royal dignity extracted by force. The barons who had cornered him at Runnymede went back to war almost immediately, the conflict historians call the First Barons War, and John died in the middle of it in October 1216, his charter formally void, his kingdom in the hands of a French prince the rebels had invited to take the throne instead. By the strict letter of what actually happened in 1215 and 1216, Magna Carta failed. It bought peace for perhaps ten weeks and did not survive its own author. What makes the story interesting is not the charter's death. It is how many times afterward somebody found it useful to bring back. John's nine year old son Henry III inherited a civil war, not a settled kingdom, and his regency government reissued the charter within weeks of John's death, stripped of its most extreme anti-royal clauses, for a straightforwardly tactical reason: it was the cheapest way to peel the moderate barons away from the French pretender and back onto the young king's side, and it worked. The charter got reissued again in 1217, alongside a newly separated Charter of the Forest, and a third time in 1225, this time in Henry's own adult name on reaching his majority, a text considered final enough that it was later entered onto the statute rolls as the authoritative version. Edward I confirmed that same 1225 text in 1297 as the Confirmatio Cartarum, folding it into the accumulating body of English statute law nearly a century after Runnymede. Most of the sixty three clauses John sealed addressed narrow, dated feudal grievances, relief payments owed on inheriting a father's land, the width of cloth sold at market, fish weirs on the Thames, and have been dead letters for centuries; only a handful remain on the statute book today. What survived every one of those repeals is a single structural idea buried inside the original bargain: that the king himself is bound by law and can be held to it by his own subjects, stated plainly enough that later centuries, arguing about entirely different grievances against entirely different monarchs, kept reaching back to 1215 and finding a phrase already built for the job. The document that could not survive its own author has, four separate times now and counting, survived everyone else who tried to bury it too.
