Matthew II of Montmorency

Matthew II or Mathieu II (died 24 November 1230), called the Great or the Great Constable, was lord of Montmorency from 1189 and Constable of France from 1218 to 1230.

He was the son of Bouchard V de Montmorency, who died in Jerusalem in 1189 and Lauretta (Laurence) de Hainaut (died 1181), daughter of Baldwin IV of Hainault. His paternal grandparents were Matthieu I of Montmorency, Constable of France and Alice FitzRoy, illegitimate daughter of King Henry I of England.

He participated in the French conquest of Normandy by Philip Augustus, where he distinguished himself during the siege of Château Gaillard in 1204. He played a vital role in the Battle of Bouvines in 1214, where he captured twelve enemy banners (in memory of this feat, the shield of Montmorency includes an additional twelve eagles or sixteen altogether instead of four previously ).

In 1215, he joined the Albigensian Crusade and became here, as Constable of France, head of the French Army in 1218. In the service of King Louis VIII of France, he conquered La Rochelle and several other cities from the English in 1224. When the King died in 1226, he protected the interests of the infant dauphin and the Queen-Regent Blanche of Castile.

He died in 1230, returning from a campaign against Anjou.
