# Simon de Montfort (died 1188)

Simon de Montfort (died 1188), sometimes known as Simon IV de Montfort, was lord of Montfort-l'Amaury from 1181 to 1188. He was the son of Simon III de Montfort, Count of Évreux and Lord of Montfort-l'Amaury. On his death, Simon III left the comté of Évreux to his elder son Amaury V, and his French properties in Montfort-l'Amaury and Rochefort-en-Yvelines to $Simon.^{:340}$

Montfort married Amicia, daughter of Robert de Beaumont, 3rd Earl of $Leicester.^{:340}$ They had two sons and a daughter:

* Simon de Montfort, 5th Earl of Leicester
* Guy de Montfort, Lord of Sidon
* Petronilla (Pernel) de Montfort, wife of Barthélemy de Roye [fr]

## Note

$^A$ His son the 5th Earl is also sometimes known as Simon IV. The discrepancy in numbering arises from confusion between Simon III de Montfort (died 1181) and his son (the subject of this article, died 1188). The latter was historically unknown, and Simon III was believed to be the father (not the grandfather) of the 5th Earl, who is therefore known as Simon IV in some sources and Simon V in others.
