Magna Cartas brought together for 800-year anniversary

Magna Carta, written in 1215, laid the foundations for democracy in Britain.

It established the principle that nobody, not even the monarch, is above the law, and it paved the way for the British justice system.

Now, 800 years since its creation, the four remaining original versions are being brought together for the first time at the British Library.
