What happened in this minute

Faced with rebellious barons, John agreed to a charter limiting arbitrary imprisonment, fixing feudal payments and promising justice that would not be sold or delayed.

The original agreement failed within months; the pope annulled it and civil war followed. It survived because it was reissued repeatedly, and because clause 39, on lawful judgement by peers, was read by later centuries as a general principle rather than a baronial privilege.

Its afterlife is larger than its text. Most of the charter concerns fish weirs, forests and widow's dowries; three clauses remain on the English statute book.

Questions and answers

What did Magna Carta actually guarantee?
Mostly specific feudal limits, but clause 39 promised no free man would be imprisoned or dispossessed except by lawful judgement of his peers or the law of the land.
Was it signed?
It was sealed, not signed. John applied his great seal at Runnymede on 15 June 1215.
Why does the page show a midday time?
No hour was recorded. The Museum uses a midday UTC marker and labels such times as approximate.
