Magna Carta and the Barons wars
Magna Carta was signed in the "First 200 years" of Belchamp Walter History.
Using Thomas Wright's H and T of Essex as a starting point for the history of Belchamp Walter there seems to be little mention of Magna Carta. However, the "players" in the Barons wars do have some connection to the area. Wright was not particularly helpful in the understanding of this period.

William de Beauchamp of Bedford - a Magna Carta Baron
De Beauchamp took part in the 1210 expedition to Ireland and the 1214 expedition to Poitiers before joining the rebellious barons in 1215 at the beginning of the First Barons' War, entertaining them at his seat of Bedford Castle; as such, de Beauchamp was one of the rebels excommunicated by Pope Innocent III.
There were two de Clare Barons in the Council of 25 Barons that were appointed under clause 61 to monitor King John's future conduct. Robert de Vere, 3rd Earl of Oxford was another Baron
The Demese Lord for Belchamp Walter was supposedly Aubrey de Vere and the villages of Clare (the home of the de Clare's), Castle Hedingham (the home of the de Vere's) are both neighbouring villages.
Magna Carta Libertatum (Medieval Latin for "Great Charter of Freedoms"), commonly called Magna Carta (also Magna Charta; "Great Charter"), is a royal charter of rights agreed to by King John of England at Runnymede, near Windsor, on 15 June 1215.
