In order to appease his nobles, John agreed to meet at Runnymede (a field near Windsor Castle) on June 15, 1215. Even as he agreed to meet, however, John did not intend to keep his word.
Presented with the Magna Carta, he agreed to its terms for one purpose only: to buy time. A contemporary chronicler, Roger of Wendover (a monk who worked at St. Albans Abbey), tells us what happened:
King John, when he saw that he was deserted by almost all, so that out of his regal superabundance of followers he scarcely retained seven knights, was much alarmed lest the barons would attack his castles and reduce them without difficulty, as they would find no obstacle to their so doing; and he deceitfully pretended to make peace for a time with the aforesaid barons...
As the king and his nobles met, John continued to recognize he was in no position to bargain. Roger of Wendover continues:
...At length, after various points on both sides had been discussed, king John, seeing that he was inferior in strength to the barons, without raising any difficulty, granted the underwritten laws and liberties, and confirmed them by his charter...
King John granted rights because he perceived he had no other choice. But another powerful man - Pope Innocent III - had a different reaction to the barons’ demands.
