In June 1189, Count Raymond V of Toulouse—in his capacity as margrave of Provence—and Adémar signed an agreement whereby the former renounced his rights in the Diois in return for the latter's fealty and homage.
[7] This is probably the occasion on which Adémar broke with the lords of Baux, and alluded to in the poem "Leus sonetz si cum suoill" by the Raimbaut de Vaqueiras.
In 1191, Countess Beatrice of Albon, who was married to Hugh III, Duke of Burgundy, signed a pact with Guillaume de Clérieu l'Abbé against Adémar.
[11] In 1193, on the occasion of the consecration of the church of Montmeyran by Bishop Falco of Valence, the count of Valentinois granted it and its prior, Ponce, some of his vassals, without effecting the freedoms and exemptions they enjoyed under him.
When he made a donation to the priory of Rompont on 31 January 1202, the day of his son Guillaume's birth, he asked God to preserve his child's life so that he could work for the glory and good of the church.
