Simon de Montfort, 6th Earl of Leicester
Simon de Montfort, 6th Earl of Leicester (– 4 August 1265), sometimes referred to as Simon V de Montfort to distinguish him from his namesake relatives, was a nobleman of French origin and a member of the English peerage, who led the baronial opposition to the rule of King Henry III of England, culminating in the Second Barons' War.
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.
During his rule, Montfort called two famous parliaments.
The first stripped the King of unlimited authority, while the second included ordinary citizens from the towns.
For this reason, Montfort is regarded today as one of the progenitors of modern parliamentary democracy.
As Earl of Leicester he expelled Jews from that city; as he became ruler of England he also cancelled debts owed to Jews through violent seizures of records.
Events in London and Worcester, for instance, led to massacres.
After a rule of just over a year, Montfort was killed by forces loyal to the King in the Battle of Evesham.

Amaury de Montfort (priest)
Amaury de Montfort( 1242 or 1243 – 1301) was the third son of parliamentary pioneer Simon de Montfort, 6th Earl of Leicester, and Eleanor of England, daughter of King John.
Amaury entered the priesthood as a young man, and held the positions of Treasurer of York Cathedral, canon of Rouen, Évreux, London and Lincoln.
He served as a papal chaplain as well.
After the deaths of his father and older brother Henry de Montfort at the Battle of Evesham in 1265( by men under the command of then Prince Edward, later Edward I, aka Edward Longshanks), Amaury fled to France with his mother, younger sister, and surviving brothers.
Amaury de Montfort soon began studying medicine and theology at the University of Padua.
His older brothers, Guy de Montfort, Count of Nola and Simon de Montfort the Younger were seeking their fortunes in Italy.
A tragic turn of events lead to the bloody 1271 confrontation between Guy and Simon and their cousin Henry of Almain( also Edward's cousin, by virtue of his father, Henry III being the elder brother of both Eleanor of England and Henry of Almain's father, Richard, Earl of Cornwall).
Henry, whom the de Montfort sons considered a traitor to their father's ideals, was attacked during mass at Viterbo, and murdered on the altar steps, resulting in the excommunication of both de Montfort sons.
While Amaury was not in Viterbo, and was not involved in the murder, Edward swore vengeance upon all of Simon de Montfort's sons, Amaury included.
Simon the younger died that year, reportedly of a tertian fever, while Guy managed to appeal to the pope( with the aid of his father- in- law), resulting in his return to the church.
In 1275, after the death of his mother at Montargis Abbey, Amaury, by then a Papal Chaplain, accompanied his younger sister Eleanor de Montfort on a winter sea voyage to Wales and her new husband, Llywelyn ap Gruffudd( the grandson of Llywelyn Fawr).
Intercepted at sea by mercenaries in the employ of now King Edward I, both Amaury and Eleanor were taken captive.
Following two paragraphs taken mainly from" Chronica, ascribed to William Rishanger, a monk of St. Albans", ed. Henry Thomas Riley[ 1865], 87, 99.
While Eleanor's captivity was gentle and relatively short- lived( she was married to Prince Llywelyn at King Edward's expense in 1278), Amaury was held' without rigour' in Corfe Castle and later in Sherborne Castle.
After requests from the Pope, Prince Llywelyn and Archbishop John Peckham of Canterbury, Amaury was released after swearing at London not to return to England unless invited by the king.
Upon his release in mid April 1282, Amaury returned to France, never again to see his sister, who died in childbirth that very year, mere months before the death of her husband Llewylyn and the annexation of North Wales to the English crown.
Amaury after some years renounced his clerical career and became a knight, apparently dying soon afterwards in Italy, possibly after 1301
Henry de Montfort
Sir Henry de Montfort (November 1238 – 4 August 1265) was the son of Simon de Montfort, 6th Earl of Leicester, and with his father played an important role in the struggle of the barons against King Henry III.
Henry's mother was Princess Eleanor of England, a daughter of King John, whose marriage to Simon further increased the foreign influence begun by the king, which was to result in great hostility by those very barons who later revolted against the king.
