What happened
Facing a rebellion by his barons, King John met them at Runnymede, a meadow beside the Thames, and on 15 June 1215 added his seal to the charter later known as Magna Carta. The National Archives holds John's own announcement of 19 June 1215, declaring that durable peace had been restored between him and the barons and freemen of the realm, witnessed at Runnymede. Its 63 clauses protected the freedom of the church, limited the king's ability to levy taxes without consultation, and guaranteed free men the right to justice and a fair trial. The National Archives describes the change bluntly: by sealing the charter, John forever changed the nature of kingship in England, since no king could any longer be seen as ruling purely on his own impulse.
Why it matters
The National Archives notes that in the century after Magna Carta, Parliament became a fundamental part of political life and it was no longer acceptable for a king to tax his people without consulting it first. Magna Carta's core idea, that the sovereign is subject to the rule of law, became a foundation of English and later Anglo-American legal and constitutional thought, cited centuries later in disputes far beyond England's borders.
How we know
Four original 1215 copies of Magna Carta survive today, two at the British Library and one each at Lincoln and Salisbury cathedrals, alongside King John's own follow-up charters and letters preserved in the National Archives.
