Geoffrey V of Joinville

Geoffrey V (French: Geoffroy), nicknamed le Trouillard, was the Lord of Joinville from 1190 until his death in late 1203 or early 1204.

[1] Following the death of Theobald, who had taken a vow to go on a crusade, Geoffrey of Joinville joined Geoffrey of Villehardouin, Matthew II of Montmorency and Simon IV of Montfort-l'Amaury approached Duke Odo III of Burgundy, asking him to fulfill Theobald's vow and lead a crusade.

Geoffrey of Villehardouin in his account make no mention of the lord of Joinville after the failed negotiation with the count of Bar.

His younger brother Robert, lord of Sailly, who was in Champagne preparing for his crusade in 1201, joined the army of Walter III, Count of Brienne, but died in Apulia en route in 1203.

His shield hung in the chapel of Krak des Chevaliers alongside those of other crusaders until, fifty years later during the Seventh Crusade, probably in 1253–54, his nephew John retrieved his shield and brought it back to hang in the church of Saint-Laurent in Joinville.

A legend dating at least to 1498 and current at the court of Duke René II of Lorraine states that he obtained his nickname from having killed a Genoese pirate with a trouille, perhaps a fishing spear.
