The Magna Carta of 1215 is generally viewed as the foundation stone of English liberty. In the City of Lincoln, one of the four surviving copies is securely displayed in the new David PJ Ross Vault in Lincoln Castle.
But today, it is recognised that the Magna Carta was just a starting point - viewed at the time as short-term pragmatism. The City of Lincoln is currently celebrating the Forest Charter of 1217 (also displayed in the vault), which restored common law to land previously designated as Royal Forests.
In 1965, Patrick Wymark starred as King John in "Left Handed Liberty", a play commissioned by the Corporation of the City of London to celebrate the 750th anniversary of Magna Carta. Playwright John Arden realised during his research that there was a hidden story about Magna Carta - what it really meant to King John and his Barons - and what that tells us about freedom today.
