In 1209, both William IV and Alfonso died and Garsenda became the natural guardian of their son and heir,
Raymond Berengar V. Initially her brother-in-law,
Peter II of Aragon, assigned the
regency of Provence to his brother
Sancho, but when Peter died in 1213 Sancho became regent of
Aragon and passed Provence and Forcalquier to his son
Nuño Sánchez. Dissension broke out between the Catalans and the partisans of the countess, who accused Nuño of attempting to supplant his nephew in the county. The Provençal aristocracy originally took advantage of the situation for their own ambitious ends, but eventually they lined up behind Garsenda and removed Nuño, who returned to Catalonia. The regency was passed to Garsenda and a regency council was established consisting of the native nobles. of the Sabran family, as used by William and Rostaing, hereditary constables of the
County of Toulouse (late 12th century) It was probably during her regency (1209/1213 – 1217/1220) that Garsenda became the focus of a literary circle of poets, though the
vida of
Elias de Barjols refers to his patron as Alfonso. There is a
tenso between a
bona dompna (good lady), identified in one
chansonnier as
la contessa de Proessa, and an anonymous troubadour. The two
coblas of the exchange are found in two different orders in the two chansonniers, called
F and
T, that preserve them. It cannot be known therefore who spoke first, but the woman's half begins ''Vos q'em semblatz dels corals amadors
. In the poem the countess declares her love for her interlocutor, who then responds courteously but carefully. Under some interpretations the troubadour is Gui de Cavaillon, whose vida'' repeats the rumour (probably unfounded) that he was the countess' lover. Gui, however, was at the Provençal court between 1200 and 1209, pushing the date of the exchange forward a bit. Elias de Barjols apparently "fell in love" with her as a widow and wrote songs about her "for the rest of his life", until he entered a monastery.
Raimon Vidal also praised her renowned patronage of troubadours. ==Retirement and later life==
