The 1215 charter wrested from King John by English barons at Runnymede — annulled within weeks but reissued repeatedly, and eventually read as the founding text of the principle that the ruler is bound by law. Magna Carta's actual clauses mostly addressed narrow feudal grievances; its civilizational significance lies in the later centuries that reimagined it as the foundation of due process, constitutional government, and the rule of law.
In June 1215, a group of English barons forced their king to press his seal onto a document at a meadow called Runnymede. Within ten weeks, Pope Innocent III declared it 'null and void and of no validity forever.' Within three years, a revised version had been reissued to hold together a kingdom at war. Within four centuries, an English lawyer named Edward Coke had transformed it into the foundation of English liberty. Today only three of its sixty-three clauses remain on the English statute books. The gap between the document and the myth it became is itself the story worth telling.
