Magna Carta

What happened

In 1215 the barons of England forced King John to seal Magna Carta, the 'Great Charter,' which limited royal power, required the king to consult his barons before levying certain taxes, and guaranteed free men protection from arbitrary imprisonment and the right to a fair trial.

Why it matters

Though it failed in the short term, Magna Carta became an enduring symbol of the rule of law and the principle that even a king is subject to it — an inspiration for constitutions and rights for centuries to come.
