That same year, he had joined in Henry the Young King's revolt against his younger brother, Richard, Count of Poitou and Duke of Aquitaine.

(Another planh for Henry, Si tuit li dol e.l plor e.l marrimen, formerly attributed to Bertran, is now thought to be the work of Rigaut de Berbezill).

In his punitive campaign against the rebels, Richard, aided by Alfonso II of Aragon, besieged Hautefort and gave it to Constantine de Born.

He gave them senhals (nicknames): Henry the Young King was Mariniers (Sailor), Geoffrey of Brittany was Rassa, and Richard, Oc-e-Non (Yes-and-No).

He had contact with a number of other troubadours and also with the Northern French trouvère, Conon de Béthune, whom he addressed as Mon Ysombart.

Be.m platz lo gais temps de pascor, which revels in warfare, was translated by Ezra Pound: ...We shall see battle axes and swords, a-battering colored haumes and a-hacking through shields at entering melee; and many vassals smiting together, whence there run free the horses of the dead and wrecked.

When Richard was released from captivity after being suspected of Conrad's murder, Bertran welcomed his return with Ar ven la coindeta sazos.

NSBM band М8Л8ТХ,in collaboration with Famine (K.P.N),released the 2015 EP "Coup de Grâce" (Russian: Удар Милосердия) in his honor.

As a result, Dante Alighieri portrayed him in the Inferno as a sower of schism, punished in the ninth bolgia of the eighth circle of Hell (Canto XXVIII), carrying his severed head like a lantern.

In her epic poem Cœur de Lion (1822), Eleanor Anne Porden portrays him fomenting discord in the Third Crusade and, because of his remorse over his involvement with Richard's imprisonment, becoming a hermit.

His memory was better served by Ezra Pound, who translated some of his songs and also based several original poems around him and his works, notably Na Audiart (1908), Sestina: Altaforte (1909), and Near Périgord (1915).

Via the influence of Pound's Na Audiart, he is also mentioned in Sorley MacLean's poem, A' Bhuaile Ghreine (The Sunny Fold).

He was the subject of a 1936 play Bertran de Born by Jean Valmy-Baisse, to which Darius Milhaud wrote incidental music.
