The dialect has its roots in 1372, when Catalan-speaking colonists were allowed to repopulate Alghero and expel the native population, after several revolts.

[1] Algherese is a regional dialect spoken by anywhere from 20,000 to 30,000 individuals, most of whom reside in the town of Alghero, located in the northwest of Sardinia.

[1] The origins of the language can be traced back to 1372, when Catalan invaders repopulated the city of Alghero after exiling the indigenous populations in Sardinia.

However, in an attempt to reverse the trend, the Regional Council of Sardinia officially recognised "Algherese Catalan" as a separate language in 1997, in order to promote its use and circulation.

[9] The following figures were obtained from the Enquesta d'usos lingüístics a l'Alguer ("Survey of linguistic usage in Alghero", EULAL) of 2004[10] and the Els usos lingüístics a l'Alguer of 2015 (EULA 2015),[11] both of which were studies conducted in the town of Alghero about the general use of Algherese in several media.

(f.) The Premi Rafael Sari, organised by the Obra Cultural de l'Alguer,[17] is a series of prizes awarded in September each year to the best literary works of poetry and prose written in Algherese Catalan.

Notable poets include Rafael Sari, Pasquale Scanu and Maria Chessa Lai.

In 2015 Carla Valentino published an Algherese translation of Antoine de Saint-Exupéry's The Little Prince.
