King John signs the Magna Charta 1215

On the 15th of June King John, at the urging of his half-brorther William Longespee,agrees to sign the Magna Carta at Runnymead. Afterwards at least 13 copies were made and sent to various parts of the country.1 The document was repudiated by him almost immediately and was described by Pope Innocent III as "not only shameful and demeaning, but illegal and unjust". The resulting animosity led to the First Baron's War.2
