At first, the interpretation of the Whig of the Magna Carta and its role in the history of the Constitution dominated in the 19th century. The constitutional history of England, published in the 1870s by historian William Stubbs, was the flood mark from this point of view.  Stubbs argued that Magna Carta had been an important step in the organization of the English nation, and he believed that the barons of Runnymede represented not only the nobility in 1215, but also the people of England as a whole, who opposed a tyrannical ruler in the form of King John.   The barons conquered London in May 1215, forcing King John`s hand and eventually leading him to negotiate with the group, and the Magna Carta was created as a peace treaty between the king and the rebels. One of four copies received from the Magna Carta of 1215 with the famous clause „we will not sell to anyone, to anyone who denies or delays the law or justice.“ Magna Carta Libertatum (medieval Latin for „Magna Charter of Freedoms“), usually Magna Carta (also the Magna Charter; The „Great Charter“) is a royal charter  of the rights that King John of England approved on 15 June 1215 at Runnymede near Windsor. [b) First conceived by the Archbishop of Canterbury Stephen Langton to make peace between the unpopular king and a group of rebellious barons, he promised the protection of church rights, the protection of barons from illegal detention, access to swift justice and restrictions on feudal payments to the Crown, which were to be implemented by a council of 25 barons. Neither side supported his commitments and the Charter was annulled by Pope Innocent III, which led to the First Barons War. John held a council in London in January 1215 to discuss possible reforms and supported talks at Oxford in the spring between his agents and the rebels.  Both sides asked Pope Innocent III to support the dispute.  During the negotiations, the insurgent barons produced a first document, which historians have described as the „Charter of Unknown Freedoms“ which, for much of its language, was based on the Charter of Freedoms of Henry I; seven articles of this document were later published in the „Articles of the Barons“ and in the Charter that followed.    1213 a group of rebellious barons met with Bishop Stephen Langton and the Pontifical Legate (representative of the Pope) to express their grievances against the king.
