VIII. Simon IV de Montfort
Born around 1160 and died in 1218 at the siege of Toulouse during the
Albigensian Crusade. Married Alice de Montmorency, date of birth
unknown, died1221. Simon de Montfort IV was count of Montfort and
through his mother also claimed the English earldom of Leicester, to
which his right was intermittently recognized by King John. He was a
participant in the Fourth Crusade (1202–4) and later led the crusade
against the Albigenses. After defeating Peter II or Aragon and Raymond
VI of Toulouse in 1213 he was proclaimed lord of Toulouse and Montauban
by the Crusaders (1215). In 1217 Raymond recaptured some of the
territory he had lost and in 1218 Simon was killed while besieging
Toulouse. He married Alice de Montmorency, daughter of Bouchard IV de
Montmorency and Laurentia of Hainault. Bouchard IV de Montmorency was
the son of Mathieu I of Montmorency and Alice (Aline) who was herself
the illigitamite daughter of Henry I of England and most probably
Sybilla Corbet. Thus Alice de Montmorency is the great great great
granddaughter of William the Conqueror through an illigitimate daughter
of WIlliam’s son, Henry I. Alice was quite a remarkable woman in her
own right, sharing her husband’s religious fervor and often accompanying
him on his crusades. She was present or nearby during many of the
battles, including the seige of Toulouse in 1217-18 where Simon met his
death. The following children are recorded: Amaury; Guy; Amicia; Simon
V, born around 1208; Robert; Petronilla.
IX. Simon V de Montfort
Youngest
surviving son of Simon IV de Montfort and Alix de Montmorency. His
paternal grandmother was Amicia de Beaumont, the senior co-heiress to
the Earldom of Leicester and a large estate owned by her father Robert
de Beaumont, 3rd Earl of Leicester in England, but King John of England
would not allow a French subject to take ownership of such an estate in
England. As a boy, de Montfort accompanied his parents during his
father's campaigns against the Cathars. He was with his mother at the
siege of Toulouse in 1218, where his father was killed after being
struck on the head by a stone from a siege engine. On the death of their
father, de Montfort's elder brother Amaury succeeded him. Another
brother, Guy, was killed at the siege of Castelnaudary in 1220. As a
young man, Montfort probably took part in the Albigensian Crusades of
the 1220s. In 1229 the two surviving brothers (Amaury and Simon) came
to an arrangement whereby Simon gave up his rights in France and Amaury
gave up his rights in England. Thus free from any allegiance to the King
of France, de Montfort successfully petitioned for the English
inheritance, which he received the next year, although he did not take
full possession for several years, and was not formally recognised as
earl. Simon was a distant cousin of King Henry III; his ancestor Simon
I de Montfort was father of Bertrade de Montfort who herself was a
paternal great-grandmother of King Henry II.
