Magna Carta

The original document is in Latin so this can only be a fairly rough approximation of the actual content. The text used is the first version in the Gutenberg collection. - Magna Carta is the most significant early influence on the long historical process that has led to the rule of constitutional law today. Magna Carta was originally created because of disagreements between the Pope, King John and his English barons over the rights of the King. Magna Carta required the king to renounce certain rights and respect certain legal procedures and to accept that the will of the king could be bound by law.
