He played a key role in the Battle of Lincoln Fair in 1217. He attempted to rival Hubert de Burgh, and as a result fell from power in 1224. His "heraldic device" is now popularly said to have been a griffin, although his coat of arms as depicted by Matthew Paris in his Chronica Majora was Gules, a cinquefoil argent.

The Famille de Mont held the castle at Mont-le-Grand near Rolle. Better known in English records as Ebulo de Montibus, Ebal II de Mont had travelled to England by 1246. A household knight of King Henry III of England, granted much land in England. By 1256 he was part of the Savoyard circle of the Lord Edward, later King Edward I of England. Recorded as a Steward in the household of King Henry III of England from 12th November 1256 until 26th May 1263.

Edward I, also known as Edward Longshanks and the Hammer of the Scots, was King of England from 1272 to 1307. Before his accession to the throne, he was commonly referred to as The Lord Edward. The first son of Henry III, Edward was involved from an early age in the political intrigues of his father's reign, which included an outright rebellion by the English barons. In 1259, he briefly sided with a baronial reform movement, supporting the Provisions of Oxford. After reconciliation with his father, however, he remained loyal throughout the subsequent armed conflict, known as the Second Barons' War. After the Battle of Lewes, Edward was hostage to the rebellious barons, but escaped after a few months and defeated the baronial leader Simon de Montfort at the Battle of Evesham in 1265. Within two years the rebellion was extinguished and, with England pacified, Edward joined the Ninth Crusade to the Holy Land. He was on his way home in 1272 when he was informed that his father had died. Making a slow return, he reached England in 1274 and was crowned at Westminster Abbey.

Eleanor of Provence was a French noblewoman who became Queen consort of England as the wife of King Henry III from 1236 until his death in 1272. She served as regent of England during the absence of her spouse in 1253.

Robert Fitzwalter was one of the leaders of the baronial opposition against King John, and one of the twenty-five sureties of Magna Carta. He was feudal baron of Little Dunmow, Essex and constable of Baynard's Castle, in London, to which was annexed the hereditary office of castellain and chief banneret of the City of London. Part of the official aristocracy created by Henry I and Henry II, he served John in the wars in Normandy, in which he was taken prisoner by King Philip II of France and forced to pay a heavy ransom.

Henry III, also known as Henry of Winchester, was King of England, Lord of Ireland, and Duke of Aquitaine from 1216 until his death in 1272. The son of King John and Isabella of Angoulême, Henry assumed the throne when he was only nine in the middle of the First Barons' War. Cardinal Guala declared the war against the rebel barons to be a religious crusade and Henry's forces, led by William Marshal, defeated the rebels at the battles of Lincoln and Sandwich in 1217. Henry promised to abide by the Great Charter of 1225, a later version of the 1215 Magna Carta, which limited royal power and protected the rights of the major barons. His early rule was dominated first by Hubert de Burgh and then Peter des Roches, who re-established royal authority after the war. In 1230, the King attempted to reconquer the provinces of France that had once belonged to his father, but the invasion was a debacle. A revolt led by William Marshal's son, Richard Marshal, broke out in 1232, ending in a peace settlement negotiated by the Church.

John was King of England from 1199 until his death in 1216. He lost the Duchy of Normandy and most of his other French lands to King Philip II of France, resulting in the collapse of the Angevin Empire and contributing to the subsequent growth in power of the French Capetian dynasty during the 13th century. The baronial revolt at the end of John's reign led to the sealing of Magna Carta, a document sometimes considered an early step in the evolution of the constitution of the United Kingdom.

Following his initial victories over royal forces, he became de facto ruler of the country, and played a major role in the constitutional development of England.

He was High Sheriff of Essex and of Hertfordshire in the years 1265–67, and as such became involved in the Second Barons' War (1264–1267).
