And at that point, now the king realizes he's locked out of London, he's going to have to start to negotiate with these guys. So they agree, the rebels and King John, that they're going to get the Archbishop of Canterbury, Stephen Langton, to be the arbitrator between the two sides. So in June 1215, based in part on that previous thousand year before document, the Charter of Liberties, the barons put together what's called the Articles of the Baron, kind of their wish list in this new relationship that they're going to have with the king. And that's going to be modified, it goes through a whole bunch of different edits in the negotiation process, but basically at the end of the day we get the Magna Carta, that's right, the Magna Carta is called the Great Charter, the Great Charter is the Magna Carta. And in this new relationship, the king's going to give up some stuff, and the rebels are going to put down their weapons, and they're going to renew the oath to the king, at least that's what they all say they're going to do. But at the basic root of the Magna Carta is in so much all of this talk about liberty, and there's certainly a few passages in there that are going to evolve into this concept of due process, that when I get arrested there needs to be due process, you know, kind of procedures that you go through, of habeas corpus, that you can't arrest me without reason, and certain other rights that are going to evolve. But really the document is addressing what these barons' concerns are, inheritance, tax, land, real estate, kind of the nitty gritty of common law, let's put it that way.
