Magna Carta is seen by many historians as one of the most important documents in history because it established first in 1215, the principle that everyone is subject to the law, even kings and queens and it guarantees the rights of individuals, the right to justice and the right to a fair trial. It is significant because it put England on the way to democracy. Over time the powers of English kings were curtailed especially in the 17th Century. Furthermore, Magna Carta is often cited as having strongly influenced the American Bill of Rights in 1791 and the Universal Declaration of Human Rightist 1948. You can see it at Salisbury Cathedral, Lincoln Castle and the British Library London.
