The Magna Carta was originally intended as a peace treaty between the king and his barons, but it became the cornerstone of liberty in the English-speaking world.
English kings became more powerful and influential after 1066, through the Norman system of centralised government and the acquisition of Normandy.
John of England
King John was a skilled politician and a forceful administrator but his cruelty and deceit made him unpopular. He was suspicious of others.
He also sought to force loyalty from his chief subjects through coercion. He took hostages from the nobles—usually their wives and children.
However, John had lost most of the Plantagenet or Angevin Empire (Normandy, Anjou, Maine and Brittany) to Philip II of France.
John needed more money for armies to recover these French possessions so he frequently levied heavy taxes upon his subjects.
Philip II defeated the English at the Battle of Bouvines in 1214.
The barons had enough so they rebelled on 3 May 1215 and captured London. John had no choice so he accepted their demands. They forced John to sign the Magna Carta (Great Charter) on 15 June 1215 at Runnymede, near Windsor. The Magna Carta limited his authority, and protected others from abuses of royal power.
It explained the barons’ feudal obligations and freedom of the Church.
Certain taxes should be levied only with the common consent of the country.
No free man would be punished or imprisoned without prior judgment according to the law of the land.
Justice would not be denied, delayed or sold. Free men should have the right to judgement by their peers.
A committee of 25 barons would monitor the king’s actions and reprimand him book if he broke any of the provisions in the charter.
The Magna Carta gave a voice, a sense of community among the barons, and accepting responsibility for the whole realm.
John had no intention of keeping his promise as he regarded the Magna Carta as unacceptable, so he appealed to Pope Innocent III to declare the charter illegal. He even promised to go on a Crusade. The Pope agreed so John declared war on his barons three months later.
Magnates appeal to France to provide a competent ruler, so dauphin Louis (later Louis VIII) invaded. John was unable to fight off the French and Louis was proclaimed king in May 1216. Louis ruled on right of his wife, Blanche of Castile (a granddaughter of Henry II).
John was forced to flee from London and travelled from one safe haven to another. (He lost the crown jewels en-route at a marshy area, known as the Wash, when the tide came in unexpectedly.)
John died from dysentery on 18 October 1216 after consuming peaches and beer. England’s senior noblemen appointed regents who ruled until Henry III came of age. Henry was hastily anointed and crowned at Gloucester on 28 October.
The Magna Carta was re-issued in 1216 to regain control. The barons saw no point in supporting a foreign king, so Louis was forced to concede defeat and withdraw in September 1217.
It was again re-issued in 1217 and 1255, and it eventually became part of the English constitution. It was a stabilising force in an increasingly unstable political situation.
The Magna Carta was not the birth certificate of freedom, but signified the death of despotism .
