Here's an excerpt from Wiki-pedia:
"Magna Carta Libertatum<span> (</span>Medieval Latin<span> for "the Great Charter of the Liberties"), commonly called </span>Magna Carta<span> (also </span>Magna Charta; "(the) Great Charter"),[a]<span> is a </span>charter<span> agreed to by </span>King John of England<span> at </span>Runnymede<span>, near </span>Windsor, on 15 June 1215.[b]<span>First drafted by the </span>Archbishop of Canterbury<span> to make peace between the unpopular King and a group of rebel </span>barons<span>, it promised the protection of church rights, protection for the barons from illegal imprisonment, access to swift justice, and limitations on </span>feudal<span> payments to </span>the Crown<span>, to be implemented through a council of 25 barons."</span>
