King John in June 1215 was forced to put his seal to "The Articles of the Barons" by a group of powerful barons who could no longer stand John's failed leadership and despotic rule. The king's Great Seal was attached to it on 15 June 1215. In return, the barons renewed their oaths of fealty to King John on 19 July 1215. A formal document to record the agreement was created by the royal chancery on 15 July: this was the original Magna Carta. "The law of the land" is one of the great watchwords of Magna Carta, standing in opposition to the king's mere will. The Magna Carta of 1215 contained clauses which in theory noticeably reduced the power of the king, such as clause 61, the "security clause". This clause allowed a group of 25 barons to override the king at any time by way of force, a medieval legal process called distraint that was normal in feudal relationships but had never been applied to a king. After a few months of half-hearted attempts to negotiate in the summer of 1215, open warfare broke out between the rebel barons and the king and his supporters.. How many months passed between the sealing of The Articles of the Barons and the barons' renewal of their oaths?
