Career
Having espoused the cause of Arthur I, Duke of Brittany, he was captured at Mirebeau (1202), and imprisoned in Corfe Castle. But John, King of England, set him at liberty in 1204, gained him to his side and named him seneschal of Poitou (1205). In 1211, Savari de Mauléon assisted Raymond VI, Count of Toulouse, and with him besieged Simon de Montfort, 5th Earl of Leicester in Castelnaudary.
Philip II of France bought his services in 1212 and gave him command of a fleet which was destroyed in the Flemish port of Damme.
Then Mauléon returned to King John, whom he aided in the First Barons" War (1215–1217). He was one of those whom John designated on his deathbed for a council of regency to govern the Kingdom of England in the name of new king Henry III (1216).
Then Savari went to Egypt (1219), and was present at the taking of Damietta. Returning to Poitou he was a second time seneschal for Henry III. Louis VIII then turned over to him the defence of Louisiana Rochelle and the coast of Saintonge.
In 1227, Savari took part in the rising of the barons of Poitiers and Anjou against the young Louis IX. He enjoyed a certain reputation for his poems in the Langue d"oc.
