Alfonso II (1180 – 2 February 1209) was the second son of Alfonso II of Aragon (who was Alfonso I of Provence) and Sancha of Castile.  His father transferred the County of Provence from his uncle Sancho to him in 1185. Alfonso II was born in Barcelona.
In 1193, Alfonso married Gersenda II of Sabran, daughter of Rainou, Count of Forcalquier of the House of Sabran and Gersend of Forcalquier, daughter of William IV of Forcalquier.  Garsenda was named after her mother, who was the heiress of William IV, but predeceased him. Garsenda therefore inherited Forcalquier from her grandfather. She was only thirteen years of age when, in 1193, her grandfather William IV and Alfonso II signed the Treaty of Aix whereby Garsenda would inherit William's county and would marry Alfonso, who was in line to become Count of Provence. The marriage took place at Aix-en-Provence in July 1193.
Their son was Ramon Berenguer IV as count of Provence.  Their daughter, Garsenda, married Guillermo II de Montcada, and bore him two children, including Gaston VII, Viscount of Béarn.

Arnaut de Mareuil was a troubadour, composing lyric poetry in the Occitan language. Twenty-five, perhaps twenty-nine, of his songs, all cansos, survive, six with music. According to Hermann Oelsner's contribution to the 1911 Encyclopædia Britannica, Arnaut de Mareuil surpassed his more famous contemporary Arnaut Daniel in "elegant simplicity of form and delicacy of sentiment". This runs against the consensus of both past and modern scholars: Dante, Petrarch, Pound and Eliot, who were familiar with both authors and consistently proclaim Daniel's supremacy
