The five Arab districts -Alhauet, Xarc, Benizamid, Algarb, and Portmany- are reorganized and divided into the "quartons" Pla de la Vila, Santa Eulalia or Del Rey Balanzat, Portmany, and Las Salinas. The first was divided into four parts which were added to the rest forming the four fiefs to be divided among the conquerors. Mongrí was given two districts. Benizamid and Algarb for having provided twice as many troops as the others, while Xarc fell to the Prince of Portugal, and Portmany to the Count of Rosselló (Nuño Sans).
