Magna Carta, agreed in 1215 between King John and his barons, addressed royal power, taxation, and legal procedure. It was not a complete declaration of modern universal democracy. The text was reissued and reinterpreted many times. Its symbolic significance grew, exerting a lasting influence on discussions of the rule of law and limits on power.
Background
Magna Carta originated as an unsuccessful attempt to achieve peace between royalist and rebel factions in 1215, as part of the events leading to the outbreak of the First Barons' War. England was ruled by King John, the third of the Angevin kings. Although the kingdom had a robust administrative system, the nature of government under the Angevin monarchs was ill-defined and uncertain. John and his predecessors had ruled using the principle of vis et voluntas, or "force and will", taking executive and sometimes arbitrary decisions, often justified on the basis that a king was above the law.
Many contemporary writers believed that monarchs should rule in accordance with the custom and the law, with the counsel of the leading members of the realm, but there was no model for what should happen if a king refused to do so.
John had lost most of his ancestral lands in France to King Philip II in 1204 and had struggled to regain them for many years, raising extensive taxes on the barons to accumulate money to fight a war which ended in expensive failure in 1214. Following the defeat of his allies at the Battle of Bouvines, John had to sue for peace and pay compensation. John was already personally unpopular with many of the barons, many of whom owed money to the Crown, and little trust existed between the two sides.
Great Charter of 1215
John met the rebel leaders at Runnymede, a water-meadow on the south bank of the River Thames, on 10 June 1215. Runnymede was a traditional place for assemblies, but it was also located on neutral ground between the royal fortress of Windsor Castle and the rebel base at Staines, and offered both sides the security of a rendezvous where they were unlikely to find themselves at a military disadvantage. Here the rebels presented John with their draft demands for reform, the 'Articles of the Barons'. Stephen Langton's pragmatic efforts at mediation over the next ten days turned these incomplete demands into a charter capturing the proposed peace agreement; a few years later, this agreement was renamed Magna Carta, meaning "Great Charter".
By 15 June, general agreement had been made on a text, and on 19 June, the rebels renewed their oaths of loyalty to John and copies of the charter were formally issued.
Although, as the historian David Carpenter has noted, the charter "wasted no time on political theory", it went beyond simply addressing individual baronial complaints, and formed a wider proposal for political reform. It promised the protection of church rights, protection from illegal imprisonment, access to swift justice, and, most importantly, limitations on taxation and other feudal payments to the Crown, with certain forms of feudal taxation requiring baronial consent. It focused on the rights of free men—in particular, the barons. The rights of serfs were included in articles 16, 20 and 28.
Its style and content reflected Henry I's Charter of Liberties, as well as a wider body of legal traditions, including the royal charters issued to towns, the operations of the Church and baronial courts and European charters such as the Statute of Pamiers. Magna Carta reflected other legal documents of its time, in England and beyond, which made broadly similar statements of rights and limitations on the powers of the Crown.
Magna Carta's influence on English medieval law
The Great Charter was referred to in legal cases throughout the medieval period. For example, in 1226, the knights of Lincolnshire argued that their local sheriff was changing customary practice regarding the local courts, "contrary to their liberty which they ought to have by the charter of the lord king". In practice, cases were not brought against the King for breach of Magna Carta and the Forest Charter, but it was possible to bring a case against the King's officers, such as his sheriffs, using the argument that the King's officers were acting contrary to liberties granted by the King in the charters.
