The 1297 feoffment of Sardinia by Pope Boniface VIII led to the creation of the Aragonese Kingdom of Sardinia and a long period of war between the Aragonese and Sardinians, ending with an Aragonese victory at Sanluri in 1409 and the renunciation of any succession right signed by William II of Narbonne in 1420. During this period the clergy adopted Catalan as their primary language, relegating Sardinian to a secondary but nonetheless relevant status with regards to the official acts and the Realm's law (the was extended to most of the island in 1421 by the Parliament). Agreeing with Fara's , the Sardinian attorney Sigismondo Arquer, author of in Sebastian Münster's Cosmographia universalis (whose report would also be quoted in Conrad Gessner's "On the different languages used by the various nations across the globe" with minor variations), stated that Sardinian prevailed in most of the Kingdom, with particular regard for the rural interior, and Catalan and Spanish were spoken in the cities, where the ruling class eventually became plurilingual in both the native and the Iberian languages; Alghero is still a Catalan-speaking enclave on Sardinia to this day. This sociolinguistic situation was reported by various authors, including the ambassador Martin Carillo (supposed author of the ironic judgment on the Sardinians' tribal and sectarian divisions: «» "few, thickheaded, and badly united"), the anonymous , a passage of which reads: «» ("they speak Catalan very well, as though I was in Catalonia"); and, finally, the rector of the Jesuit college of Sassari, Baldassarre Pinyes, who wrote in Rome: «» ("as far as the Sardinian language is concerned, Your Paternity, know that it is not spoken in this city, nor in Alghero, nor in Cagliari: they only speak it in the towns").
