A few years after the major anti-Piedmontese revolt, in 1811, the priest Vincenzo Raimondo Porru published a timid essay of Sardinian grammar, which, however, referred expressively to the Southern dialect (hence the title of ) and, out of prudence towards the king, was made with the declared intention of easing the acquisition of Italian among his fellow Sardinians, instead of protecting their language. The more ambitious work of the professor and senator Giovanni Spano, the "Ortographia sarda nationale" ("Sardinian National Orthography"), although it was officially meant for the same purpose as Porru's, attempted in reality to establish a unified Sardinian orthography based on Logudorese, just like Florentine had become the basis for Italian.
